Publisher: 1991Dissertation note: R ice polishing is the finally ground powdered material obtained in the polishing of kernels of rice after the hulls has been removed. Rice polishing furnishes almost equivalent energy as other cereals and at the same time is a good source of protein and water soluble vitamin especially Thiamine and Niacin. Its fiber content is comparatively higher than the cereal grains. It also contains a considerable amount of oil which is Viable to become rancid, if stored for longer period, so its oil should be extracted to improve its quality and to store it for a longer period. Rice polishing (sol. ext.) at present is not utilized efficiently for feeding of poultry due to presence of certain growth inhibitory factor.
The present study was planned to replace maize with rice polishing (sol. ext.) at different levels in the broiler rations and to find out suitable treatments of autoclaving to reduce/remove the growth inhibitory factors. Two experiments were conducted using day old "Indian River" broiler chicks as experimental birds.
In the first experiment the replacement of maize with rice polishing (sol. ext.)at different levels was studied. Growth rate, feed comsumption, efficiency of feed utilization and dressing percentage of chicks were recorded.
There was a non significant difference in weight gain of chicks fed rations containing 0, 10, 20 & 30 percent rice polishing (so!. ext.). However, the feed utilization was reduced significantly (P < 0.01) as the level of rice polishing (so!. ext.) was increased in the rations.
In the Experiment II, effect of different treatments on the nutritive value of rice polishing (sol. ext.) was studied. Treatments included autoclaving for 30 minutes, autoclaving for 60 minutes and autoclaving for 30 minutes with 20 percent moisture. autoclaving treatments significantly (P < 0.01) improved the growth rate and feed efficiency of chicks as compared to the control ration (without autoclaving). Best weight gain and feed efficiency was found in the chicks fed ration containing rice polishing (sol. ext.) autoclaved for 60 minutes. This indicated that autoclaving had reduced/removed the antinutritional/growth inhibitory factor(s) present in the indigenous rice polishing. The autoclaving with 20 percent moisture was in effective to further improve the nutritive value of rice polishing for broilers.
CONCLUSION:
The findings indicate a significant growth depression along with poor utilization of feed by chicks fed rations containing higher levels of rice polishing (sol. ext.).
Autoclaving treatments improved the nutritive value of rice polishing (sot. ext.), as indicated by better growth rate and feed utilization of the chicks. Autoclaving with increased, moisture was ineffecting in further improving the nutritive value of rice polishing for broilers.

Publisher: 1991Dissertation note: Minerals are the essential nutrients having significant role in the animal nutrition because of both their excess and deficiency produce detrimental effect en the productive and reproductive performance of the animals. In the present study the levels of macro and micro mineral elements were studied in crossbred and non-descript cattle of Punjab and Sind provinces of the country. For this purpose M6 blood samples from both the local breeds been' randomly collected from districts of Lahore, Gujranwala, Gujrat, Sargodha, Jhang, Faisalabad, Okara and Sahiwal of Punjab province and Karachi , Hyderabad and Tharparkar of Sind province. These areas were included in the study because of higher population of dairy cattle. The blood samples were collected from four different classes of cattle i.e.. calves, heifers, dry pregnant and lactating non pregnant. The serum was separated from the blood samples. Ser4Jm samples were analysed f or calcium, phosphorus, sodium, potassium, magnesium, zinc, copper, manganese and iron. Sodium and potassium were analysed on flame photometer while calcium magnesium, 7)n4 copper, manganese and iron were analysed on atomic absorption spectrophotometer. Double beam spectrophotometer was used for the estimation of phosphorus. The data thus obtained was subjected to statistical analysis using complete randomize design arid the differences in the means were tested using DMR test.
The mean values of serum minerals in crossbred cattle of Punjab province were Calcium 7.04 mg/100ml, phosphorus 2.94 mg/100 ml, sodium 125.17 meq/L, potassium 4.67 meq/t, magnesium 2.49 mg/100 ml, zinc 0.81 ppm, copper 0.69 ppm, manganese 0.45 ppm and iron 1.26 ppm. Highly significant difference (P<0.0l) in the values of serum minerals of crossbred cattle were found among districts while difference among various classes of crossbred cattle were non significant (P>0.05). The mean values far non descript cattle of Punjab and Sind provinces were, calcium 6.83 mg/100 ml phosphoras 2.83 mg/100 ml. sodium 130.10 meq/L, potassium 4.96 meq/L.. magnesium 2.55 mg/ 100 ml, zinc 0.86 ppm, copper- 0.72 ppm, manganese 0.47 ppm and iron 1.32 ppm.. Highly significant difference (P<0.01) was found among various classes in different districts of Punjab and Sind province. The variation in the mineral status of the animals under study might be due to many factors Like breed of animals, plane of feeding practices, composition of soil, source and supply of water and climatic conditions of the region etc.
The serum mineral values observed f or crossbred and non--descript cattle of Punjab and Sind provinces of the country were relatively lower than the exotic breeds reported in the literature. While comparing the serum mineral values of crossbred with non-descript cattle, lower values for most of the minerals were found in crossbred cattle except calcium and phosphorus.
Severe deficiency of serum phosphorus, zinc and copper was observed in both breeds of cattle of Punjab and Sind provinces of the country, while a mild deficiency of serum sodium and manganese was recorded. Crossbred animals were found more prone to mineral deficiencies as compared with the non-descript animals.

Publisher: 1985Dissertation note: An experiment was designed to study the effect of Sodium hydroxide treatment on the nutritive value of rice straw and its effect on growth rate, feed consumption feed efficiency and digestibility when fed to sheep. Sixty four lambs were included in the trial and randomly divided into four groups having four replicates in each group. Four rations A, B, C and D untreated and treated with 2%, 4% and 6% NaOH were prepared and alloted randomly to four groups of lambs. The experiment lasted for 84 days.
There was a significant improvement (P<O.05) in the weight gain and feed efficiency of lambs fed ration containing rice straw treated with 6% NaOH as compared with lambs fed ration containing untreated rice straw. Significant difference (P<O.05) in feed consumption were also observed between the lambs fed treated and untreated rice straw. The lambs fed ration containing untreated straw consumed significantly (P<O.OS) less feed than the lambs fed ration containing rice straw treated with 4%, & 6% NaOH. The digestibility trial revealed that the lambs fed ration containing rice straw treated with 2%, 4% and 6% NaOH had significantly higher (P<O.05) values of digestibility of dry matter, crude protein, crude fibre, ether extract and nitrogen free extract than the lambs fed ration containing untreated rice straw. However, non-significant difference (P<O.05) in digestibility were observed between the lambs fed rations treated with sodium hydroxide at different levels.
The study indicated that nutritive value of rice straw was improved by the treatment of sodium hydroxide at a significant level(P>0.05) for fattening the animals. Treatment with 6% Sodium hydroxide was proved significantly better (P>0.05) as lambs fed ration D containing rice straw treated with 6% NaOH gained more weight showed better feed efficiency and digestibility.

Studies On The Chick Growth Inhibition Of Rapeseed Meal
by Zaboor Khan, M | Muhammed Yaqoob Malik | Nisar Ahmed | Saghir Ahmed Jafri.
Material type: ; Format:

; Literary form:
not fiction
Publisher: 1984Dissertation note: Rapeseed meal is one of the by-products of the oil industry obtained after the extraction of oil, generally by expeller method. The meal i. a good source of vegetable protein which could be incorporated in different poultry feeds. The use of rapeseed meal as a vegetable protein source in poultry feeds is limited due to its growth inhabitary effects. The meal contains a sulfur containing glucoside called 'Goitrin' which during digestion by an endogenous enzyme, 'myrosinase'is hydrolyzed to volatile, 'isothiocyanate', an antinutritional factor for poultry.
The present study was designed to determine the effect of growth-inhabiting factor in indigenous rapeseed meal on the growing chicks and to improve its nutritive value for poultry feeding, through different mechanical and chemical treatments like solvent extraction, autoclaving, water treatment and ferrous sulphate treatment.
For this purpose two experiments were designed. In both the experiments day old 'Indian Rivers" broiler chicks were used as experimental animals. In the first experiment effect of feeding different levels of rapeseed meal on the growth rate, feed consumption and feed utilization of the chicks were determined. Effects of rapeseed meal on the internal organs, dressed weight and dressing percentage of the chicks were also studied.
Feeding different levels of untreated rapeseed meal in lieu of soybean meal in 1st experiment showed non-significant differences in weight gain, feed utilization, dressed weight, dressing percentage and weights of internal organs amongst the groups and replicates except the thyroid gland. This might be on account of the lower content of 'Allyl-isothiocyanate the antinutritional factor present in the indigenous rapeseed meal. However, there was a slight depression in the growth rate of the chicks fed rations containing different levels of rapeseed meal.
It was observed that feeding of rapeseed meal at more than JLO% of the ration significantly increased (P/O.OJ) the weight of thyroid glands. There was almost a proportionate increase in the weight of thyroid glands of the chicks fed rations with increasing levels of rapeseeed meal.
The second experiment was designed to study the effect of different mechanical and chemical treatments on the nutritive value of rapeseed meal. For this purpose, 'apeseed meal after autoclaving, solvent extraction, water and ferrous sulphate treatments was incorporated at 20% level in the experimental rations.
The treatments of the meal did not improve the weight gains, feed utilization and dressed weight of the chicks as compared with untreated rapeseed meal. This might be due to the reason that the indigenous rapeseed meal contained a lower level of glucosinolate, the antinutritional factor responsible for growth inhabition in chicks and thus the effect of different treatments to reduce the level of the glucosinolate of the meal was not significant. There was, rather more depression in growth rate and feed utilization of the chicks fed rations containing water treated rapeseed meal. This might be attributed to the formation of more toxic compounds during the microbial fermentation in water treatment of the meal.
Conclusion
Results of the experiments indicated almost a proportionate decrease in the growth rate and feed utilization of the chicks fed rations containing different levels of rapeseed meal. However, there was no significant difference in the weight gain, feed consumption and feed efficiency of the chicks, fed rations containing different levels of rapeseed meals.
There was no effect of different mechanical or chemical treatments of rapeseed meal on its nutritive value except water treatment, which, rather produced adverse effects on the growth rate and feed utilization of the chicks. This might be due to the fact that the indigenous meal contained a lower level of 'Allyl-isothiocyanate' the antinutritional factor responsible for growth inhabition of the chicks.
Recommendations
Based on the results of the present study it is recommended that rapeseed meal upto a level of 10% could be incorporated in broiler rations without impairing the growth rate and feed utilization of the chicks.

Publisher: 1991Dissertation note: To determine the mineral status of indigenous cattle about 300 blood samples were collected from Lahore, Gujranwala, Sheikhupura, Sahiwal, Okara, Faisalabad, Sargodha, Jhang and Gujrat districts of Punjab, and Hyderabad, Mirpurkhas and Karachi districts of Sindh because of having high population of cattle. The blood samples were collected from four different groups of cattle (1) calves (2) heifers (3) dry pregnant (4) lactating non pregnant. The serum was separated from blood samles by centrifugation. Serum sample were analysed for Calcium, Phosphorus, Magnesium, Sodium, Potassium, Zinc, Copper, Manganese, Iron and Cobalt. (Calcium, Phosphorus and Magnesium were analysed on spectronic 20. Sod)1I1 and Potassium were analysed on flamphotometer. Zinc, Copper, Manganese, Iron and Cobalt were analysed on atomic absorption spectrophotometer)The data thus obtained was subjected to statistical analysis by using complete randomized design and the differences in means were tested by using (LSD Test) least significant difference test.
The mean values of serum mineral in cattle of Punjab were, Calcium, 9.34+ 0.41 mg/100 ml, Phosphorus 4.660.25 mg/100 ml, Magnesium 2.02±0.23 mg/100 ml, Sodium 290.61 11.8 mg/l00 ml, Potassium 18.55±0.56 mg/100 ml, Zinc l.06±0.09 ppm, Copper 1.05±0.14 ppm, Manganese .56±0.04 ppm, Iron 1.38±0.06 ppm and Cobalt 0.089±0.007 ppm. The mean value of serum mineral in cattle of Sindh were Calcium 8.83±0.43 mg/100 ml, Phosphorus 4.48±0.23 mg/l00 ml, Magnesium 2.08+0.21 mg/100 ml, Sodium 273.43±18.69 mg/100 ml, Potassium 18.21±0.72 mg/100 ml, Zinc 0.96+0.12 ppm Copper 0.96±0.11 ppm, Manganese 0.54±0.05 ppm, Iron 1.2±0.157 ppm and Cobalt 0.085.±0.009 ppm. Nonsignificant difference in values of serum minerals in cattle (P> 0.05) were found within different groups and between provinces, while significant differences were found between districts (P< 0.05). This variation may be due to different plan of nutrition composition of soil water and climate etc.
The serum Calcium values were almost normal but mild deficiency was found in cattle of Gujrat, Gujranwala, Sheikhupura, Jhang districts of Punjab while Karachi and Mirpurkhas districts of Sindh. The serum Phosphorus level was low in cattle of Punjab and Sindh and acute deficiency was observed in Faisalabad, Gujrat, Shéikhupura and Jhang districts of Punjab, Karachi and Mirpurkhas districts of Sindh. The serum Magnesium values showed deficiency in Sheikhupura, Sargodha and Jhang districts of Punjab and Karachi district of Sindh. The serum Sodium values were almost normal in cattle of all districts. The serum Potassium values were normal in cattle of all districts except Sargodha in Punjab. The serum Zinc values were low in animals of all districts and severe deficiency was found in cattle of Okara, Sahiwal and Sheikhupura districts of Punjab and Karachi Hyderabad, and Mirpurkhas districts of Sindh. The serum Copper values of animals were found low in Okara, Lahore and Sheikhupura districts of Punjab and Karachi and Mirpurkhas districts of Sindh. The serum Manganese values were found deficient in districts of Gujranwala, Gujrat, Sahiwal, Sheikhupura and Jhang in Punjab and Hyderabad district of Sindh. The serum Iron values were normal in animals of both provinces of Punjab and Sindh except Lahore,, Sargodha, Jhang and Sheikhupura districts of Punjab and Hyderabad district in Sindh. The serum Cobalt values were found low in cattle of Sahiwal, Okara and Sheikhupura districts of Punjab and Karachi and Mirpurkhas districts of Sindh. The overall mineral status of cattle of Punjab province was slightly higher than Sindh except Magnesium mineral and the difference was nonsignificant while between the groups of animals were found non significiant. The variation in serum mineral values in cattle might be due to plan nutrition, low mineral status of soil, composition of water and climate etc.

Publisher: 1995Dissertation note: A study was undertaken to find out the appropriate level of matri (Lathyrus sativus linn) as vegetable protein source in broiler ration. Seven experimental rations containing 0, 10, 15 and 20 percent treated and untreated matri were tried on two hundred and ten day old broiler chicks for the period of 50 days. The chicks were randomly divided into seven groups of thirty chicks each. The birds reared on starter ration upto 28 days of age and on finisher ration for rest of the experimental period. The results showed that the starter ration A (control) containing no matri was best in promoting weight gain, feed consumption and feed utilization. The ration B containing 10% matri (autoclaved) gained more weight and consumed more feed and was better in feed efficiency. Finisher ration A (control) containing no matri was the best in promoting weight gain and the ration B containing 10 percent matri (autoclaved) stood second in number as for as weight gain, feed consumption and feed efficiency was concerned. At the end of the experiment dressing percentage and economics of different rations were also calculated Dressing percentage values were statistically non-significant so far as the cost per Kg live weight wasconcerned, ration B was cheaper while ration A was the cheaper while ration A was the cheapest as compared to all other rations. It was concluded that the ration containg 10% matri can safely be used in broiler ration without showing any deleterious effect on growth and feed consumption.

Publisher: 1994Dissertation note: A study was undertaken to investigate the effect of different levels of diethyistilbestrol on the performance of broiler chicks. The performance of the broilers were studied under the headings of weight gain, feed consumption, feed efficiency, dressing percentage, market finishing and carcass quality, Tenderness and juiciness, residual effect of the hormone, economics and mortality.
Four different levels 0mg, 10mg, 15mg and 20mg of diethyistilbestrol hormone were tried on one hundred and eighty day old broiler chicks, divided into four different experimental groups A, B, C and 1). 1-lormone was implanted at the age of 29 days and the birds were kept for further two weeks after the implantation of the hormone upto the age of 42 clays.
Non significant difference was noticed among weight gain, feed consumption and feed efficiency of chicks before the implantation of the hormone upto 28 days of age but presented significant difference among weight gain and feed efficiency after the implantation of the hormone (from 29-42 days of age). Feed consumption showed non significant difference but Dressing percentage, Marketing finishing and carcass quality and tenderness and juiciness presented significant differences after implantation of the hormone.
It was concluded that hormone implantation significantly affected the growth rate, feed efficiency, dressing percentage, market finishing and carcass quality, tenderness and juiciness of the meat and 15 rng level of the hormone proved best for implantation which
was comparatively cheaper and cost per kg. of live weight was decreased at this level. Therefore, net profit per chick was greater. No residual effect of the hormone was detected in the meat.

Publisher: 1994Dissertation note: A research study was conducted to find out the effect of virginiamycin, oxytetracycline and Furazolidone as a growth promoter in broiler rations.
Two hundred and forty day old broiler chicks were divided into four groups of 60 chicks each. Each group was further subdivided into three replicates of 20 chicks each.
Two experimental rations (starter and finisher) were prepared and fed to experimental chicks upto 50 days of age.
Virginiamycine, oxytetracycline and Furazolidone were mixed to experimental rations at the level of 10 mg/kg feed. The effects of these additives on weight gain, feed consumption, feed efficiency, mortality, weights of internal organs and residual effect on meat were recorded.
Feed and water were given libitum. Continuous light was provided for 24 hours.
The results revealed non-significant differences among weight gain, feed consumption and feed efficiency of the chicks fed on starter ration.
However the results obtained from 29-50 days showed significant difference (P <0.05) in weight gain, feed consumption and feed efficiency. The best weight gain was obtained with oxytetracycline supplementation followed by virginiamycine, furazolidone and the controlled group. Maximum feed was consumed by the birds fed on control ration. The best feed efficiency was noticed with birds fed on ration supplemented with oxytetracycline.
The results obtained from 0-50 days showed highly significant difference (P < 0.01) in weight gaiu of the birds. Feed consumption and feed efficiency also showed significant difference (P<0.05).
The maximum weight gain was noticed with birds fed on oxytetracycline supplementation followed by virginiamycine and furazolidone supplementation, while the least weight gain was shown by the birds fed on control ration.
Maximum feed was consumed by the birds fed on control ration and the least feed consumption was observed with birds fed on oxytetracycline supplementation followed by virginiamycine and furazolidone. The poor feed efficiency was observed with the birds fed on control ration.
Dressing percentage and weight of internal organs showed statistically non-significant.
The residual effect of antibiotics was not found in the chicken meat.
From the present study it was concluded that the addition of antibiotics in the broiler rations proved economical as compared to control.

Effect Of Different Antioxidants In Rice Polishing On The Performance Of Broiler Chicks
by Aziz, M | Prof. Dr. Nisar Ahmad Mian | Dr. Talat Naseer Pasha | Prof. Dr.
Material type: ; Format:
print
Publisher: 1997Dissertation note: The oxidation of rice polishing and complete feed, can significantly decrease nutritional value. The end result is a loss in nutrient quality, impairmeI of health of birds, reduction in performance and increased production cost.
The detrimental effects of oxidation can be minimized by adding antioxidants to rice polishing. Quality antioxidants interrupt the reaction and control subsequent losses in nutrient value. Antioxidant protect the quality of rice polishing and feed as formulated by the nutritionist to achieve maximum growth and feed efficiency.
An investigation was undertaken to study the comparative value of various antioxidants to minimize (Peroxide value, free fatty acid number) the effect of oxidation in rice polishing on the performance of broiler chicks. Six experimental rations viz, A, B, C, D, E and F were prepared for the said purpose. Ration A served as negative control (Fresh rice polishing without antioxidant), Ration B served as positive control (Rancid rice polishing without antioxidant). Ration C (Feedox) 125 gm/ton of rice polishing, Ration D Santoquin 500 gm/ton of rice polishing, Ration E Oxistat 125 gm/ton of rice polishing, Ration F Butylated hydroxy toluene (BHT) @ 500 gm/ton of rice polishing.
One hundred and eighty, day old broiler chicks were randomly divided into six groups having thirty birds in each group and which were further subdivided into three replicates comprising of ten birds in each. The body weight, feed consumption and feed conversion ratio were recorded at the end of each week. Pancreas weight, dressing percentage, mortality percentage and comparative study of antioxidants were determined at the end of experiment. However, the peroxide value of rice polishing at fresh, rancid and on weekly basis was analyzed. The experiment lasts for six weeks.
The weight gain of the birds fed on various experimental rations A, B, C, D, E and F from 5-6 weeks of age were 645.0, 538.33, 655.33,709.17,663.33 and 643.0 gms respectively. Significantly more weight gain (709.17gm) was observed in the birds fed on ration D containing santoquin. Overall total weight gain of birds fed on experimental rations A to F were 1628.8, 1343.7, 1484.2, 1608.8, 1508.1 and 1471.1 gms respectively. However, the results revealed non-significant differences among weight gain of birds.
The results of feed consumption indicated that birds fed on different experimental rations A, B, C, D, E and F from 0-6 weeks of age were 3063.77, 3082.0, 3277.2, 3247.13, 3360.0 and 3223.33 gms respectively. However, apparently the birds fed on ration E containing Oxistat antixodant consumed more feed as compared to other rations.
The data on feed efficiency showed that birds fed on different experimental rations A, B, C, D, E and F from 5-6 weeks of age were 2.558, 2.756, 2.473, 2.334, 2.590 and 2.540 respectively. Significantly (P< 0.05) better feed utilization was observed in birds fed on ration D containing Santoquin as compared to chicks fed on ration E containing Oxistat and B containing rancid rice polishing, but there was no difference in the birds fed on ration E, A, F and C. However, the feed efficiency of birds from 0-6 weeks of age fed on experimental rations A to F were 1.969, 2.209, 2.122, 1.943, 2.133 and 2.191 respectively which revealed non-significant difference among the rations.
Present results revealed that weight of pancreas of birds fed on different experimental rations A, B, C, D, E and F from 0-6 weeks of age were 2.692, 3.735, 3.064, 2.89, 3.232 and 2.839 gms respectively. Significantly more weight of pancreas was observed in the birds fed o ration B containing rancid rice polishing. However, non-significant difference were noticed in the birds fed on other experimental rations.
The peroxide value in rice polishing at first and the end of 6th week of experiment of rations A, B, C, D, E and F 0.8, 61.2, 2.1, 1.4, 2.4 and 2.5, at 6th week 10.3, 80.7, 6.3, 3.3, 5.9 and 7.6 respectively.
It was concluded that Santoquin was the best antioxidant in controlling the oxidation process in rice polishing as compared to other antioxidants, i.e., Oxistat, Feedox and BHT used in the present experiment.
RECOMMENDATIONS
1. For further study various antioxidants with various levels and various sources of fat containing ingredients (rice polishing) at various levels of inclusion should be tested.
2. This type of study should be performed with fresh ingredients.
3. Different methods i.e. control of air, moisture, temp. Of storage period, light etc. should adopted to minimize the development of rancidity.
4. Storage duration of rice polishing should be at least six weeks.
5. Storage of feed should be at controlled environment.
6. Processing of rice polishing should be in such a way that lipase enzyme not become active.
7. Santoquin (Ethoxyquin) antoxidant proved to be best in controlling oxidation process in rice polishing i.e. peroxides formation than Feedox, Oxistat and BHT antioxidants.

Publisher: 1997Dissertation note: Methionine is one of the dietary essential amino acid. In formulating poultry rations methionine is generally deficient and thus supplemented to fulfill the requirement. The level of melhioiiine, recommended by NRC for maximum growth and feed effIciency, estimated as 0.5% in starter and 0.42% finisher rations, respectively. in the body niethionine can also be synthesized from homocysteine through transmcthylation reaction. For methionine to be synthesized, methyl groups are required. Cholinels known as a methyl group donor in the body. But it has to be activated and converted to betaine before methyl groups are liberated. Betafin (Betain Anhydron), a commercial product is available, used to spare choline and methionine in poultry rations.
The experiment was designed to evaluate biological availability of Belafin for methioiiine sparing in broiler chickens. For this purpose 250 day 01(1 chicks were taken, divided into five groups, i.e. (A, B, C, I) and E), then these were further subdivided into five replicates each. Five starter and finisher rations (A) Adequate methionine (B) low methionine LM (C) LM + choline (D) LM + Betafin 1:1 and (E) LM -I- I3etafin 1:2; formulated and fed to their respective groups. The experiment lasted for 42 days in two phases i.e. (Starter and Finisher).
The parameter studied were (1) Feed intake (2) Weight gain (3) Feed conversion ration FCR (4) Mortality (5) Dressing percentage (6) Economics.
Average feed intake per bird was 3942±63.08, 3609±44.75, 3439.21±28.28, 3763.36±58.04 and 3775.46±48.35 (P <0.05), weight gain 2127.59±23.59, 1732.78±4 1.32, 1720.00±34.96, 1911.02±47.16 and 1890.76±39.75 grams (P <0.05), FCR 1.84 ±0.0322, 2.08±0.032, 1.99±0.026, 1.99±0.024 and 1.99±0.025, (1'<0.05), Dressing percentages were observed non-significant (P>0.05), for groups i.e. (A, B, C, D and E) respectively. The adequate methionine (A) feed had higher price per unit, but had significantly higher weight gains and better feed efficiency.

Publisher: 1999Dissertation note: The study was designed to compare the efficacy of different feed additive anticoccidials and coccidiosis vaccines A total of 240 day-old-broiler chicks were purchased and raised for 42 days in good husbandry and hygienic conditions. The birds were randomly divided into eight groups i.e. A, B, C, D, E, F, G and H Comprising of 30 birds each. Groups A was uninfected unmedicated control while group B was infected unmedicated control. Groups C, D, E and F were given commercial feed having anticoccidials Coxistac, Sacox, Elancoban and Avatec respectively. Groups G and H were given unmedicated feed and were vaccinated at day 3 and 10. All the groups except that of group A were given primary and challenge doses of infection on day 22nd and 35th . The oocysts count was done on 5th 6th and 7th day after each infection. The feed consumption and weight gain were recorded weekly. Record of mortality was kept and postmortem of dead birds was also performed. The data collected was subjected to statistical analysis using Two Way Analysis of Variance and Least Significant Difference (LSD) test, to detect the differences between treatments and means.
It was concluded that Sacox (salinomycin sodium) as anti-coccidial in feed revealed significant (P< 0.05) difference among all the treatments in terms of weight gain, feed efficiency (FCR), oocyst count and reduction in mortality. The results of other anti-coccidials were not satisfactory, while both the vaccinated groups i.e. group G and H performed well in terms of oocyst count and decrease in mortality but their weight gain and feed efficiency were not good.
The results of this study will help to the feed millers in choosing the best feed additive anti-coccidial, while the farmers will get choice amongst anti-coccidial drugs or vaccines.

Publisher: 2000Dissertation note: Canola a genetically improved variety of rapeseed after extraction of oil, as a meal, is the best supplement protein source among the vegetable protein sources which can be incorporated in different classes of poultry rations.
The present experiment was conducted to study the long term effect of canola meal feeding on the performance of 216 layer chicks from 19th 29th weeks. The birds were divided into six main groups, having 36 layers each and further sub-divided into 3 replicates of 12 layers each. Each replicate was treated as an experimental unit. All the managemental programs like, feeding, watering, vaccination, lighting and temperature were provided according to the recommended requirements for Babcock B300 layers.
Six experimental rations, A, B, C, D, E and F were prepared containing 0, 5, 7.5, 10, 12.5 and 15% canola meal in the layer mash, while with the same designation of rations, 0, 9, 12, 15, 18 and 21% canola meal containing starter and grower rations were fed during the previous phase of the project (Phase-I). The rations were formulated and provided according to the Babcock B300 strain requirement.
In this project, effect of feeding different levels of canola meal was checked in lieu of soybean meal on feed consumption, feed efficiency (Kilogram of feed per dozen eggs) egg production, weight of twelve eggs, egg shell thickness, chemical composition of eggs, organoleptic evaluation and economics.
Feed consumption, per dozen egg weight and egg production were significantly lower (P<O.01) with rations containing different canola meal levels as compared to soybean meal diet. While best feed conversion ratio (kilograms of feed per dozen eggs) was observed with canola meal containing ration that is significantly lower (P<O.01) as compared to soybean meal containing diet. Egg shell thickness was also significantly higher (P <0.01) with rations containing canola meal as compared to soybean meal.
Chemical composition and organoleptic evaluation of the eggs from the hens fed on soybean meal or canola meal containing ration did not show any pronounced effect. While the economics of the experimental rations indicated that rations contain canola meal were cheaper as compared to soybean meal containing rations. The overall picture of the whole experiment revealed that canola meal can replace completely soybean meal in laying phase. But it has little problem of poor feed intake which was may be due to picking problem of the birds due to smaller particle size of canola meal.
RECOMMENDATIONS
Based on the present study following are the recommendations:
1. With the energy compensation of the layer ration canola meal can be incorporated upto 15% dietary level.
2. A wide range of glucosinolates is present in canola quality of rapeseed i.e. 1-3O.smol/gm DM meal. It is very critical for formulation.
3. Canola meal should be incorporated in layer mash ration after pelleting in order to avoid the low feed intake problem.
CONCLUSIONS
Results of the present study reveals that canola is one of the best vegetable protein sources that can replace completely soybean meal in the layer diets with respect to the performance of the birds upto 30th week of age.

Comparative Effect Of Raw & Stabilized Rice Polising On The Performance Of Broiler Chicks
by Dawood Ahmad | Dr . Nisar Ahmad Mian | Dr . Muhammad | Dr . Talat Naseer Pasha.
Material type: ; Format:

Publisher: 1999Dissertation note: Owing to cheap and abundant availability of rice polishing in Pakistan, researchers are attempting to enhance its inclusion level in poultry ratio. It also compares well with cereal grains in chemical composition. But the prevalence of rancidity due to high fat and other toxic factors limiting its use in poultry. Hence rice polishing was subjected to extrusion cooking for stabilizing the fat and improving its quality. The extrusion cooking of rice polishing was done at National Feed Mill, Sheikhupura.
Present experiment was conducted to observe the comparative effect of Raw and stabilized rice polishing on the performance of broiler chicks. Seven experimental rations (Starter and Finisher) were prepared designated as A, B, C, D, E, F and 0. All rations were isocaloric and isonitrogenous. Starter and Finisher ration "A" was kept as control containing no rice polishing. In rations B, C, and D raw rice polishing was used at levels 20, 25 and 30% respectively while in rations E, F and 0 stabilized rice polishing was used at the same levels. Starter rations were fed for 28 days and finisher ration from 29 days to 42 days.
Two hundred and ten (210), one day old broiler chicks were randomly divided into 7-groups having thirty chicks in each groups and which were further sub-divided into three replicates comprising ten chicks in each.
Results of present study indicated that maximum weight gain was observed in birds fed on ration "E" whereas second best was observed in chicks fed on ration "B". The birds fad on rations E, F and 0 (extruded rice polishing) gained better weight than those fed on rations B, C and D (raw rice polishing) at same levels and of control ration.
Best feed utilization per unit gain was observed in chicks fed on ration "E" and it began to decline as level of rice polishing (raw and extruded) raised to 30%. Overall feed efficiency of birds fed on rations containing (extruded rice polishing) was better than those fed on ration containing raw rice polishing and at the same levels.
During the whole experimental period, 4% mortality was observed In birds fed on different rations. This was due to heat stress .e. due to high ambient temperature (June, July months). The average dressing percentage was 55.20, 56.00, 54.5, 54.40, 54.77, 56.07 and 54.34 respectively. A non-significant difference was observed regarding dressing percentage. The average pancrease weight also showed a non-significant difference among treatments. However, a slight increase in pancrease weight was observed in birds fed on rations containing raw rice polishing. This might be due to secretion of bile (Lipase Enzyme). With respect of cost per kg live weight gain, the rations containing extruded rice polishing were observed slightly economical as compared to ration containing raw rice polishing.
RECOMMENDATIONS
As extrusion processing holds great promise as a mean to improve efficiency of nutrient utilization, it is therefore recommended that the use of extruded feedstuff, especially for non-traditional, feed ingredients should be promoted in poultry ration. The level of extruded rice polishing can be raised safely upto 25%.

Publisher: 2000Dissertation note: The study was conducted to determine the effects of different commercially available antifungal compounds on feed quality and broiler performance. Six experimental rations i.e. A, B, C, D, E and F were prepared for this trial. Ration A was positive control (containing no antifungal compounds), ration B (containing 0.5 kg Mycostat / ton), ration C (containing 0.5 kg Mycocurb\ ton), ration D (containing 15% moisture without any antifungal compounds), ration E (containing 1 .0 kg Mycostat / ton with 1 5% moisture) and ration F (containing 1 .0 kg Mycocurh/ ton with 15% moisture).
These experimental rations were stored for one month. During storage period the representative feed samples were collected from all the rations and were analysed for mould growth and aflatoxins level.
A total of 240 day-old-broiler chicks were randomly divided into 6 groups having 40 birds in each group and which were further subdivided into 4 replicates comprising of 10 birds in each. The body weight, feed consumption and feed conversion ratio were recorded at the end of each two weeks. Mortality percentage and comparative economic study of antifungal compounds were determined at the end of experiment. The experiment was completed in six weeks.
The results of feed consumption indicated that birds led on different cxperimen(af rations A, B, C, D, E and F from 0-6 weeks of age were 3173, 3230, 3215, 2310, 1972 and 2243 gnis respectively. However, apparently the birds fed on ration B containing Mycostat consumed more Iced as compared to other groups.
The weight gain of the birds fed on various experimental rations A, B, C, D, E and F from 0-6 weeks of age were 1710, 1770, 1 760, 965, 845 and 980 gms respectively. However, apparently more weight gain was observed in the birds fed on ration B containing Mycostat.
The data on feed efficiency indicated that birds fed on different experimental rations A, B, C, D, E and F from 0-6 weeks of age were 1.855, 1.82, 1.83, 2.392, 2.34 and 2.283, respectively. However, better feed utilization was observed in birds fed on ration B containing Mycostat as compared to chicks fed on other rations.
The feed mould count values for groups D, E and F were 4.0 10E4, 1.1 10E4 and 1.0 10E4 respectively, and the Aflatoxins levels for groups D, E and F were (G1<0.1, G2<0.1, B1-33.5 B2-2.4), (GI<0.l, G2<O.1, B1-26.5, B2-1.9) and (G1<0.1, G2<0.l, B1-35.5, B2-2.5) respectively.
It is concluded that Mycostat is comparatively better antifungal compound commercially available as compared to Mycocurb in terms of improving the performance of the broiler birds.

Effects Of Phytase On The Performance Of Broilers Fed On Sorghum Based Diets
by Manzoor Ahmed | Prof. Dr. Nisar Ahmad Mian | Mr. Anjum Khalique | Mr. Athar.
Material type: ; Format:

Publisher: 2001Dissertation note: In Pakistan, sorghum (jawar) occupies 4th place with a production of 218.6 thousand tons (Economic survey of Pakistan 2000-200 1) after wheat, maize and rice. Its use is limited in poultry feed because it contains antinutritional factor i.e. tannin, phytic acid (68% of Total phosphorus). The low tannin sorghum varieties can replace maize up to 50%, and sorghum high in tannin can replace maize up to 25% in poultry diet.
While considering different nutrients for broiler feed formulation minerals are also very important. Among minerals phosphorus plays an important role for poultry production. Balancing the phosphorus in compound feed is difficult task because less than one third of the phosphorus in the feedstuffs of plant origin is biologically available to monogastric animals (NRC, 1994). The organic phosphorus exists in the bran of grain, consisting mainly of phytic phosphorus,
Phytase is an enzyme that liberates P from vegetable materials, destroys the antinutritional properties of phytate. Phytase was one of the first enzyme to be described in the literature. As early as 1907 the release of phosphorus from an organic phosphorus containing substrate was described by Suzuki and others (Maga 1982). The enzyme "phytase" is now known to cause the release of phosphate from phytic acid by catalyzing a series of hydrolysis reactions.
Keeping in view the above facts an experiment was conducted to study the effects of phytase on the performance of broiler fed on sorghum- based diets.
Two hundred broiler chicks were purchased from Big Bird Poultry Breeders and divided in to five groups. These groups were further subdivided in four replicates, having ten chicks in each. The chicks were kept in starter batteries for the first four weeks and then shifted to grower batteries till the end of experiment (six week). Five starter and five finisher rations (sorghum based) A, B, C, D, and E were prepared. "A" was control having 0.45 and 0.35% AP in starter and finisher rations respectively. While B, C, D and E supplemented with phytase enzyme (600 FTU/kg of feed) having 0.40, 0.35, 0.30 and 0.25% AP in starter and 0.30, 0.25, 0.20 and 0.15% AP in finisher rations respectively. Light, feed and fresh clean water was provided round the clock.
The parameters studied were weight gain, feed consumed, feed conversion ratio, dressing percentage, mortality, phosphorus availability and economic. The data thus collected was subjected to statistical analysis. The results indicated that the weight gain of chicks fed on rations B and C were comparable to ration A (control). The chicks fed on rations D & E significantly (P<O.05) showed poor perfonnance as compared to those fed on rations A, B and C. Significantly (P<O.05) more feed was consumed by chicks fed on ration B as compared to those fed on D and E. However, nonsignificant difference was observed between feed consumption of chicks fed on rations A, B and C. Non-significant differences were observed in feed conversion ratio of chicks fed on different experimental rations (Starter & Finisher). However, the feed conversion ratio of chicks fed on ration "C" was comparable to the chicks fed on ration "A"(Control). The dressing percentage of the chicks showed improvement with supplementation of phytase enzyme but the difference were non-significant between chicks fed on different experimental rations. Phytase supplementation significantly (P<O.05) improved the availability of P in chicks fed on rations B, C, D, & E as compare to those fed on ration A (control). The total cost incurred on one kg live weight for chicks fed on rations A, B, C, D and E were Rs. 31.98, 30.58, 31.86, 33.18 and 33.76, respectively. While net profits per one-kg live weights were Rs. 16.02, 17.41, 16.14, 14.82 and 14.24 respectively. Maximum profit was observed in birds fed on ration "B" supplemented with phytase enzyme. Overall it was found that by using phytase enzyme in broiler ration more profit could be earned.
RECOMMENDATION
1. By the use of phytase in poultry feed phosphorus availability could be increased.
2. Use of phytase enzyme is economical.
3. By the use of phytase enzyme 0.1% available phosphorus can be decreased in the broiler ration.

by Farhan Ahmad | Dr. Anjum Khalique | Dr. Azhar | Prof. Dr. Talat Naseer Pasha.
Material type: ; Format:

Publisher: 2003Dissertation note: The objectives of this study were, to produce phytase on large scale and to make sure its effectiveness in utilization of phytate P in diet of growing pullets. The fungal species Aspergilus niger was used as fermentation organism, for the production of extra cellular high active phytase enzyme on defatted rice bran through solid state fermentation (SSF). Cultivation conditions for phytase production including substrate; water ratio, temperature, were optimized. Phytase production was found maximum after 96 hrs of incubation, at 40% moisture level. The developed conditions were then utilized for production of phytase on large scale basis. After production, the activity of enzyme was measured. Then this phytase was supplemented to layer grower negative control diet (NPP 0.3 1%) in different proportions i.e., 0, 1000, 1500 and 2000 tg/kg of diet to increase the bioavailability of phosphorus. Rice polishing was used as a major ingredient, as it contains high phytate contents. During experiment, feed intake, weight gain and FCR of birds were measured on weekly basis. Excreta were collected at the end of experiment to determine the effect of phytase on P availability. Also samples of toes were collected and percentage toe ash was measured.
The total feed consumption from 9-18 wk of pullets fed on diet A, B, C and D was 2919.7, 2861.9, 2913.6 and 2930.9g respectively. Weigh gain was 743.15, 718.37, 749.70 and 768.OOg respectively and FCR was 3.93, 3.99, 3.89 and 3.81 respectively.
The results showed that when low P diet (0.31% NPP) was supplemented with different levels of phytase, there was slight improvement in the performance of birds with the addition of phytase in respect of feed consumption, weight gain and FCR. Group "D", fed with diet containing 0.31% non phytate phosphorus (NPP) plus phytase (2000 igfKg of diet) showed best performance than all other groups. Group "B", fed with diet containing 0.3 1% NPP plus phytase (1000 j.tg/Kg of diet), showed poorest performance. While the performance of group "C", fed with diet containing 0.3% NPP plus phytase (l500.ig/Kg of diet) was almost similar to control group (A) fed with diet containing 0.4% NPP without phytase. The data was subjected to statistical analysis, using completely randomized design (CRD). The statistical analysis revealed non-significant difference (P> 0.05) among all treatments in respect of feed consumption, weight gain and FCR. The results were non-significant; it indicates that even lowest level of phytase (1OO0tg/Kg of diet) with 50% DCP was sufficient to maintain optimum performance of pullets. It also indicates that further investigations are required to decrease the DCP level below 50% with addition of different levels of phytase.
Phosphorus availability percentage of groups A, B, C and D was 42.67, 50.00, 54.68 and 60.67% respectively. While percentage of toe ash was 11.9, 11.2, 12.1 and 12.7% respectively. The results of P availability measured from the P intake through feed and P voided through feces showed that there was significant linear increase (P < 0.05) in percentage of P availability with increase in level of phytase. In group D (2000ig phytase 1Kg of diet) there was highest availability of P while in control group there was lowest availability of P.
In respect of toe ash there was significant difference (P < 0.05) among different experimental pullet groups. Highest toe ash percentage was in D (2000.tg phytase /Kg of diet) group while lowest in group B (l000.tg phytase /Kg of diet). Toe ash percentage of group C (1 500.tg phytase 1Kg of diet) was slightly better than group A (control). Statistically groups A and C were better then group B, but non-significant among each other. Toe ash was higher (P < 0.05) in group D than all other groups except group C.
Conclusion
- We can reduce 50% of inorganic source of phosphorus i.e. DCP with the addition of phytase, in the diet of growing pullets, with out any adverse effect on the performance of pullets.
- Other benefit of phytase supplementation is that we can improve availability of P and ultimately can reduce P in feces of birds and thus can reduce the environmental pollution.
- Further investigations are required to reduce DCP level more than 50% or even up to 0 levels with the addition of phytase.

Publisher: 2005Dissertation note: Aflatoxins, the flungal toxic metabolites produced by Aspergillus flavus and Aspergillus parasiticus are potent toxin as natural contaminants ol' lce(l stulis. Aflatoxin effects all species of animal and poultry resulting. depressed growth. production and immunity against diseases. The research study was conducted 0 study the adsorption potential of Yeast sludge against atlatoxins in broiler chicks. For this two hundred and forty day-old broiler chicks were randomly divided into twenty four units each containing 1 0 chicks and these twenty lour units erc divided into six treatments.
Six experimental rations (starter and finisher) A (100 ppb allatoxins). AI (100 ppb aflatoxins + 1% yeast sludge). B (200 ppb aflatoxins). B 1 (201) pph aflatoxins + 1% yeast sludge). C (300 ppb afiatoxins). Cl (300 pph aflatoxins 1% yeast sludge) were prepared and 1d to the experimental chicks Iron) six to forty-two days of age. The aflatoxins produced by Aspergillus parsilicus Ii 0111 own laboratory. The data thus collected in terms of weight gain. feed consumption. FCR, serum total protein, serum albumin, alanine transaminase (ALT). aflatoxin concentration in liver and mortality were analyzed statistically. The results of this study showed that weight gain, feed consumption and FCR were not significantly different as compared to groups which were supplemented with yeast sludge, but total serum protein, serum albumin, antibody titer of' ND and aflatoxin concentration in liver were high in groups supplemented with yeast sludge as compared to groups which were fed diets containing only aflatoxins and were not supplemented with yeast sludge.
The results revealed that the ration with 1% yeast sludge supplementation and having 100 ppb aflatoxins showed less mortality, ALT activity and aflatoxins concentration in liver and high serum total protein, serum albumin and antibody titer of ND as compared to groups which were not supplemented with yeast sludge. In case of 200 ppb aflatoxins and 1% yeast sludge results showed less mortality. ALT activity and aflatoxins concentration in liver and high serum total protein. Serum albumin and antibody titer of ND as compared to groups which were not supplemented with yeast sludge.
In case of 300 ppb aflatoxins and 1% yeast sludge results showed less mortality, ALT activity and aflatoxins concentration in liver and high serum total protein, serum albumin and antibody titer of ND as compared to groups which were not supplemented with yeast sludge.
The present research indicates that use of yeast sludge against aflatoxins showed best results, however 1% yeast sludge contains a very limited amount (0.26)% of Mannan oligosaccharide as aflatoxin adsorbent. So, there is a need to use higher levels of yeast sludge or improve its adsorbing ability such as centrifugation and ultrasonication. This research is the first step in this field and it is recommended to launch a full fluged project to reveal the other beneficial characteristics of yeast sludge such as immune boaster, probiotic activity, provision of highly digestible inorganic material, blocking colonization of pathogens, provision of nutrients that cannot be used by pathogens and stabilizes pH in the rumen etc.

Publisher: 1983Dissertation note: The iodine which is so necessary for normal thyroid function is obtained from the food we eat, and to a much less extent: , from the water we drink4 Iodine deficiency is the commonest cause of goitre. Deficient dietary intake is the most important single cause of iodine deficiency, and its role is especially important in districts with a high prevalence of simple goitre. The best known areas of high prevalence of iodine deficiency in the world are mountanious, e.g. the Alps, the Himalayas and the Andes, but high prevalence was also found in certain low lying areas. In countries where most of the population receive iodized salt and where iodine-containing foods are widely distributed, this condition is becoming less common.
Pakistan is one of the developing countries of the world which faces malnutrition as a serious public health problem. Trace mineral imbalance and deficiency are one of the causes of malnutrition in people of the country. Surveys carried Out in recent years have shown goitrous areas particularly North-West of Pakistan. Iodine prophylaxis has been introduced in some of such areas with success and the disease has been practically controlled.
The present study was therefore designed to determine the iodine status of the people of Lahore city and collect information of the factors that interfere with the availability and utilization of iodine.
A total number of 1,000 patients of thyroid dysfunction were selected at random at the Atomic Energy Medical Centre, Mayo Hospital Lahore. The observations on the incidence of iodine deficiency and its relation to age, sex, type of thyroid diseases and financial status of the patients were recorded.
The map of Lahore city was divided into five experimental areas and the numbers of patients from each area were counted.
Clinical tests showed a wide variety of thyroid problems including iodine deficiency goitre, simple goitre, Hyperthyroidism, Hypothyroidism, puberty goitre, thyroid cancer,etc. Some patients were proved to be normal.
Results of the survey showed that there was a highly significant (P/ 0.01) occurrence of thyroid patients in the experimental area II, i.e. North West of Lahore city. It showed the highest frequency of 42.1% of thyroid patients, as compared to other experimental areas I, III, IV and V having 19.3, 18.8, 9.0, 10.8% frequency respectively.
Comparison of different thyroid diseases showed that there was highest profusion of iodine deficiency goitre in the patients. There was highly significant (PLO.01) occurrence of iodine deficiency goitre of 37.0% as compared to simple goitre, hypothyroidism and miscellaneous thyroid diseases, which were 14.2, 13.5, and 4.2% respectively. Prevalence of iodine deficiency goitre was also significantly (PLO.05) higher i.e. 37.0% in occurrence as compared to hyperthyroidism)i.e. 27.0%. Only 4.1% patients were found normal.
It was revealed that there was highly significant (L 0.01) occurrence of iodine deficiency goitre in the patients of the experimental area II as compared to the experimental areas IV,V,III and I.
The survey revealed that there was highly significant (L 0.01) occurrence of the patients having thyroid problems from 30-40 years of age as compared to the patients of thyroid dysfunction from 0-10, 10-20, 20-30, 40-50 and 50-above years of age.
It was observed that there was a much higher occurrence,i.e 76.2 % of thyroid complaints in females than in males.i.e 23.8%. The results showed that there was a higher occurrence of iodine deficiency goitre in females, i.e 30.2% as compared to males,i.e 6.8%. )
The survey revealed that thyroid dysfunction was prevalent in the patients belonging to the three categories of incomei.e upper class, middle class and lower class. But there was no significant difference between the three classes.
Out of a total number of 50 samples of drinking water from the five experimental areas 30 samples were found deficient in iodine,i.e having lower than 40 microgram of iodine per liter. 20 Samples were found normal in iodine level having more than 40 microgram of iodine per liter of water. The highest iodine level of 44.0 microgram per litre of water was found in the experimental area V and the lowest iodine level,i.e 20.0 microgram per litre of water was found in the experimental area II, having the highest thyroid dysfunction rate of 40.3% of the patients.
There was highly significant (P/_0.01) occurrence of iodine deficiency in the blood of the patients having thyroid dysfunction. Iodine deficiency in the blood was highly significant (P/_0.01) in the patients of group II as compared to the patients of group III.
The results of water test and blood test were in agreement with the findings of the general survey of the patients suffering from thyroid dysfunction. The experimental area II had the highest number of patients suffering from thyroid dysfunction, i.e 42.1% and the larger number of patients having deficiency of blood iodine was also observed in the same' area,i.e 70%. The lowest iodine level of 20.0 microgram per litre of water was also found in the same experimental area.

Publisher: 2006Dissertation note: An experiment was conducted to determine the apparent metabolizable energy (AME) and true metabolizable energy (TME) of indigenous vegetable protein sources in cockerels by force feeding method. Six indigenous vegetable protein sources viz. soybean meal, canola meal, rapeseed meal, guar meal, sunflower meal and linseed meal were used. Thirty five 18 weeks old broiler breeder cockerels were used in such a way that five birds were force fed 25 gm of each feedstuff for estimation of AME and TME. Five birds were kept fasted to serve as negative control for determination of metabolic faecal and urinary endogenous energy excretions. The pre-feeding fasting period was 24 hours and excreta was collected over a period of 24 hours. The gross energy of test ingredients and the excreta was measured by using adiabatic oxygen bomb calorimeter. Proximate analysis for moisture, crude protein, ether extract, crude fiber, ash and nitrogen free extract were carried out. All had almost similar dry matter and ether extract values. Sunflower meal and canola meal had less CP% because of presence of sulphur containing amino acids. The observed AME values for soybean meal, canola meal, rapeseed meal, guar meal, sunflower meal and linseed meal were 2556, 1920, 1887, 1847, 1629 and 2061 Kcal/Kg, respectively. Soybean meal had the highest value 2556 Kcal/Kg and sunflower meal had the lowest value 1629 Kcal/Kg. The observed TME values for soybean meal, canola meal, rapeseed meal, guar meal, sunflower meal and linseed meal were 2694, 2053, 2022, 1992, 1764 and 2198 Kcal/Kg, respectively. Soybean meal had the highest value 2694 Kcal/Kg and sunflower meal had the lowest value 1764 Kcal/Kg. Endogenous energy ranged from 2.93 Kcal/gm to 2.95 Kcal/gm with the average of 2.94 Kcal/gm. It was also found that crude fiber has indirect relationship with both AME and TME. While, it has also come to notice that ether extract has direct relationship with gross energy of the feedstuff.

Publisher: 2007Dissertation note: Buffalo breeding, an important form of livestock production, is practiced throughout the world and makes an important contribution to overall global agricultural production. The buffalo is an important provider of milk and meat in our country. Cottonseeds and its by-product, e.g., cottonseed cakes are mostly used as protein source in livestock rations. In the present study gossypol contents of cotton seed cake in the experimental rations was determined. Moreover, the effects of diets containing cotton seed cake on the semen quality in buffalo breeding bulls were investigated. For the determination of free gossypol contents seven samples of cotton seed cake used in the experimental rations were collected. These samples were analyzed for the free gossypol contents using American Oil Chemist's Society Official Method, Ba 7-58.
To study the effects of gossypol on semen quality, fifteen adult buffalo breeding bulls were randomly divided into three equal groups named A,B and C. Bulls in group A were fed control ration "A" (without gossypol). Animals in group B were fed ration "B" which contained 15% cotton seed cake (containing free gossypol contents of 0.525 g/kg of ration), and those in group C were given ration "C" containing 30% cotton seed cake (which contained free gossypol @ 1.05 g/kg of ration). Experimental rations were fed to the buffalo bulls of respective groups according to their requirements as per NRC recommendation. The amount of free gossypol fed to the experimental animals of group B and group C were 5.25 and 10.5 g/bull/day.
In addition, buffalo bulls in all the three groups were given good quality chaffed green fodder and clean water ad-libitum.
Experimental animals in all groups were fed ration "A" for one month (pre-treatment period). The experimental rations were fed to buffalo bulls of respective groups for a period of two months from June to July, (treatment period). Experimental animals in each group (A, B and C) were fed with experimental ration "A" (without gossypol) for another two months period from August to September (post-treatment period). Body weight measurements were taken at monthly interval and semen samples were collected on weekly intervals and evaluated for physical characteristics of semen quality during the course of study.
The amount of free gossypol of cotton seed cake
averaged 0.35 ± 0.0 1345 percent whereas in rations A, B and C, it was 0, 52.5 and 105.0 g/kg respectively.
The gossypol contents of cotton seed cake presenf in the experimental rations did not cause any sign of gossypol toxicity. Moreover, among the groups, the mass motility, individual motility, motility after dilution, motility after freezing, sperm concentration and live% were not affected but volume, p11 and body weight of buffalo bulls was affected significantly. Among the periods, pH, motility after freezing and live spermatozoa percent differed significantly but volume, mass motility, individual motility, motility after dilution did not differed significantly.

; Nature of contents: ; Literary form: Publisher: 2007Dissertation note: A trial was conducted to determine the effect of supplementing sodium bentonite, to find the effectiveness of sodium bentonite on the growth performance of Sahiwal male calves. Twelve animals of almost same age and weight were selected from the available stock at Animal Nutrition Centre, Rakh Dera Chahl, Lahore. These animals were divided into three groups and fed a standard ration "A" according to their nutrient requirements. Rations of group B and C were supplemented with sodium bentonite at the rate of 2.5 and 5.0 per cent while group A served as control. The trial was run for a period of 90 days with normal managemental practices. During the experimental period body weight gain and feed consumption of the individual animals was recorded. At the end of the experiment the data were analyzed statistically. The result of the experiment suggested that addition of sodium bentonite had statistically non-significant effect on the body weight gain, feed consumption, and feed conversation ratio and rate of passage of digesta through the gastro-intestinal tract. Based on the results of this trial it could be inferred that supplementation of sodium bentonite may have some beneficial effect on the performance of calves. However, use of this clay over extended period of time needs to be investigated for any adverse effect in future

Publisher: 2009Dissertation note: Use of bovine somatotropic hormone (bST) for increased milk production has been widely investigated in dairy cattle, whereas very little work has been done in buffaloes. To observe the effect of bST on buffalo for long term duration study was planned with the objectives to investigate the effects of long term use of bST on milk production, milk composition, reproduction, hematological and biochemical parameters in Nili-Ravi buffaloes. For this study 30 lactating Nili-Ravi buffaloes with similar milk production and stage of lactation were selected and randomly divided in to two groups A and B with 15 animals in each group. The group A (0 bST) served as control while animals in group B (+bST) were given injection of bST (250 mg Boostin-250/animal) at 14d interval. Nutritional requirements of experimental animals were met through available green fodder (45-50kg/day) supplemented with concentrate ration @ half of milk production. The milk production was significantly (P<0.05) increased by 18.04 % in treated group compared with control. The results showed that there was no significantly variations in parameters like milk composition, dry period and lactation length, calving interval in both the groups. The postpartum estrous period and service period were significantly (P< 0.05) improved which reflected positive effect of bST on reproductive parameters. However, the difference in services per conception was non-significant. Small variations were found in the prevalence of contagious and non contagious diseases in both experimental groups during the study period. The differences among body weights, hematological and biochemical parameters were also non-significant expect blood urea nitrogen (p< 0.05). The proceeds over a lactation period of 305 days was PKR. 4227.0 with the use of bST.
Second trial was conducted to study the effect of dose interval of bST in Nili-Ravi buffaloes. For the proposed study 21 Nili-Ravi lactating buffaloes with similar milk production and stage of lactation were randomly divided into three groups A, B and C with 7 animals in each group. The group A was injected with full dose of bST hormone (250 mg/animal) with trade name of Boostin-250 at an interval of 14 days, while animals in group B were given injection on alternate days with divided dose of 36 mg/animal. Group C was kept as control. Duration of study was 5 months and the animals were kept on green fodder supplemented with concentrate ration half of milk production. The concentrate ration had 17.2% CP and 72.0% TDN. The milk production increased by 18.35% and 15.27% in-group A and B compared with group C (control) but increase was non-significant (P>0.05) . Similarly data revealed that dose interval had no affect on milk contents, reproductive and hematological parameters in all the experimental groups.
In a third trial feed digestibility and efficiency for milk production was studied. For the study fourteen Nili-Ravi buffaloes at their mid lactation with almost same level of milk production were randomly divided into two groups A and B with seven animals in each group. The group A was kept as control, while group B was injected bST hormone (250 mg/animal) at an interval of 14 days and continued for 60 days. The nutritional requirements of animals in both the groups were met through TMR according to NRC recommendations. The milk production was increased by 7.0% in. treated group (B) as compared with control group (A) and the increase was statistically non-significant (P>0.05). However, the feed efficiency for milk production was significantly improved (P< 0.05) in treated group. The differences in milk composition (Fat, SNF, TS and Protein percent) body weight gain digestibility of dry matter and other nutrients in treated and control groups were found non-significant (P>0.05).
The fourth trial was conducted to determine the effect of energy on milk production and its quality under the influence of bST hormone in Nili-Ravi buffaloes. Multiparous (n12) buffaloes with mid lactation and similar level of milk yield were selected and randomly divided in to three groups i.e. A, B and C with four animals in each group. All the experimental animals were injected bST with trade name of Boostin - 250. The dose level was 250 mg per animal and injection was given at fortnightly interval during study period. The nutritional requirements of three groups animals were met through TMR with varying levels of energy (15% low and 15% above the recommendations of NRC). The milk yield was significantly higher (p<O.O5) on medium and high energy ration but the difference of milk yield was non significant (p>O.O5) between medium and low energy diets. The milk components and body weight gain were similar on all rations, while feed efficiency and nutrient intake (except ether extract) in low energy diet was significantly higher (p<O.O5) from two other rations. It may be concluded that 15% higher energy than recommended by NRC favoured milk production in Nih Ravi buffaloes when they were injected bST hormone.
Conclusion
On the over all there was consistency of results for milk production and milk composition with reference to available literature. However, some reproductive parameters including postpartum estrus and service period were significantly improved with the use of bST hormone. This effect has not been reported in the previous literature which needs to be further investigated and verified. Similarly the dose level in buffaloes needs to be further studied.

Publisher: 2010Dissertation note: The cost of feed, as percentage of total production costs, accounts for about 5 0-60% of ruminant feeding systems. According to estimates, Pakistan is deficient by 40 and 80 percent in forage and concentrate feeds. For economical production of balanced feed for livestock, poultry, fish and pet animal, non-conventional feed resources need to be explored to find solution to the existing gaps. For this purpose the present study was conducted to determine the nutritional profile, processing and utilization of rumen contents in buffalo feed. The study was conducted in three phases. In phase one, bovine rumen contents were collected from the slaughter house near Bakar Mandi and were analyzed at Nutrition laboratory, UVAS, Lahore. In phase two, rumen contents were ensiled with wheat straw, with and without addition of 5% molasses for a period of 60 days at Ravi Campus, Pattoki. Proportion of rumen contents and wheat straw were 1:1 on DM basis. Wheat straw was also treated alone by reducing its DM to 43% with water and by addition of 5% molasses. The pH of silages of rumen contents and wheat straw, with and without molasses were 4.8 and 4.92, respectively. The silage containing rumen contents and wheat straw showed a little increase in C.P. In phase three, a metabolic trial was conducted at Buffalo Reaearch Institute, Pattoki, in which 15 male buffalo calves were fed the diets having total mixed ration (TMR) (Ti), TMR with 43% DM in wheat straw (T2), 50% TMR plus 50% ensued wheat straw and rumen contents (T3), TMR with 5% molasses in wheat straw (T4), and 50% TMR plus 50% ensued wheat straw with rumen contents and molasses (T5). The data thus obtained was statistically analyzed using one way analysis of variance (ANOVA) technique. The significant differences between means were tested by Duncan's Multiple Range test. Among the treatments containing ensued rumen contents, DM intake, DM and nutrient digestibility as well as N retention were significantly (P<O.05) higher for silage without molasses treatment. However, the digestible energy (D.E) was significantly (P<O.05) higher for silage treated with molasses. When means were compared there were significant differences among all treatments for DM intake, DM, CP, CF, cellulose and hemicellulose digestibility, D.E and N retention but not for T5 and T3, T4 and T2 and T2 and Ti in case of DM intake and EE, NDF and ADF in case of digestibility. It was concluded that rumen contents could replace 50% of conventional TMR without any adverse effects on digestibility and health of buffalo calves.

Publisher: 2009Dissertation note: Many reports have illustrated the limitations of feed stuffs in meeting the mineral needs of poultry and other monogastric species. Many feed millers base their estimates of requirements on the NRC. However, the commercial feed industry has adjusted these levels based on their own 'gut feel' rather than on any scientific basis. So, when poultry feed is formulated on this basis, it may not fulfill the bird's nutritional requirement due to their tabulated values instead of actual, resulting in some nutritional disorder and many other related problems.
Therefore it becomes more imperative that we must have nutrient profile of our local feed stuff. The present study has been designed to ascertain mineral profile of the poultry feedstuffs (cotton seed meal, wheat bran, corn gluten meal 60% and corn gluten meal 30%) locally available to the industry and prepare a document on the basis of data analyzed which will be used as a ready reference through out the country. Evaluation of the minerals (Ca, Na, K, P) bioavailability of these ingredients and commercial broiler starter feed in broiler was also be determined. For this purpose poultry feed ingredients and commercial broiler starter feed were procured from a commercial feed mill. For bioavailability of minerals a total of 200 day old Hubbard broiler chicks were used and allocated to five (5) dietary treatments (A, B, C, D and E) in such a way that each treatment was replicated 4 times with 10 chicks in each replicate. Diet A was of corn- soybean meal. Diet B, C, D and E was contain cotton seed meal, wheat bran, corn gluten meal 60% and corn gluten meal 30 %, respectively. The data obtained was subjected to statistical analysis using Analysis of Variance Technique. The difference among the treatment means was tested through Duncans's Multiple Range (DMR) Test.
The maximum Ca bioavailability was observed in group B (61.56±5.51%) which was commercial feed, followed by group C (46.30 ±4.29) containing cotton seed meal, E (41.61±8.05) containing corn gluten meal 60%, A (37.60±5.0) containing control(corn- soybean meal), D (35.12±9.20) which was wheat bran and F (22.3 1±8.04) containing corn gluten meal30%. There was a significant (P<0.05) difference in bioavailability of Ca in group A between the groups B and F, respectively.
The maximum P bioavailability was observed in group A (58.48± 3.59) which was control feed, followed by group D (52.32±3.09) containing wheat bran, B (49.06±5.81) containing control feed, E (45.94±7.12) containing corn gluten meal 60%, C (40.45±4.55) which was cotton seed meal and F (38.68±8.3 1) containing corn gluten meal 30%. There was a significant (P<0.05) difference in bioavailability of phosphorus in group A among the group B C, E and F, respectively.
The maximum Na bioavailability was observed in group B (77.50± 5.86) which was commercial feed, followed by group C (75.03±3.28) containing cotton seed meal, F (73.62±4.75) containing corn gluten meal 30% feed, D (73.10±4.5 1) containing wheat bran, A (65.05±7.16) which was control diet and E (58.40±7.34) containing corn gluten meal 60% respectively. There was a significant (P<0.05) difference in bioavailability of Na in group A among the groups B, C, D, E and F respectively.
The maximum K bioavailability was observed in group A (94.17± 0.85) which was control feed, followed by group B (93.98±0.51) containing commercial feed, E (93.05±1.05) containing corn gluten meal 60% feed, D (91.62±0.84) containing wheat bran, F (90.69±0.69) which was corn gluten meal 60% feed and C (90.26±1.07) containing cotton seed meal respectively. There was a significant (P<0.05) difference in bioavailability of K in group A among the groups C, D, E and F, respectively.

Publisher: 2010Dissertation note: The study was conducted to determine the relative bioavailability of minerals in different cereals grain commonly used in broiler ration. For this purpose experiment was conducted in the Poultry Experimental Shed, University of Veterinary and Animal Sciences, Lahore, 200 day old broiler chicks and were randomly distributed into five equal treatment groups A, B, C, D & E containing commercial control diet, maize, wheat, rice tips, rice polish respectively. Each treatment had 4 replicates having 10 chicks each. Birds were placed on floor for first 10 days then were shifted to cages on ii day with replicate groups were fed on experimental feed. Feed and water were provided ad libitum. Body weight and feed consumption were recorded weekly and FCR and weight gain was also calculated accordingly.
The experiment was ended at day 21, all birds were weighed and feed consumption was recorded to calculate weight gain and FCR. Two birds per replicate were randomly selected and 5m1 blood was taken from wing vein prior to slaughtering. After slaughter, organ weights, left tibia bone were taken. Blood samples, left tibia bone ash, and excreta samples were collected for analysis of macro minerals (Ca, P, K and Na).
Data when statistically analyzed showed that there was a significant differences (P<0.05) among body weights, Birds fed wheat showed the highest (P<0.05) body weight compared to control diet. Feed consumption & FCR values showed significant difference (P>0.05). Organ weight revealed that liver & heart weights were non-significant (P<0.05) among different treatment groups however significantly (P>0.05) highest weights were observed for birds fed diet containing control diet.
Amount of available Ca in plasma was significantly higher (P>O.05) when rice tips was fed as compared to phosphorus which showed significant (P>O.05) differences among treatments and the amount of available minerals Ca, P, Na and K in bone ash were also significant (P<O.05) among birds fed control, maize, wheat ,rice tips, rice polish. The amount of available macro minerals (Ca, P, Na and K) in feed showed a significant difference (P<O.05) when birds were fed wheat, rice tips and rice polish. The amount of macrominerals (Ca, P, K and Na) in excreta significantly showed (P<O.05) difference among all treatments. The bioavailability of macrominerals (Ca, P, K and Na) showed significant (P<O.05) among treatments groups. However bioavailability of phosphorus showed non-significant (P>O.05) difference of group fed control diet and rice polish. The results showed that among energy sources wheat, rice tips and maize minerals contents are compare with rice polish.

Publisher: 2010Dissertation note: Pakistan's economy is mainly based on agriculture and livestock production. Fodder crops cover 16 to 19% of the total cropped area in the country. The country is still deficient in total digestible nutrients (28.62 million tons) and digestible protein (1.76 million tons), which is still not sufficient to meet the feeding requirement of livestock in the country. The shortage of fodder is a major limiting factor for livestock growth. A study was planned to focus on nutritionally improved high yielding sorghum variety (JS2002) on two different topographically sites viz Okara and Bhakar districts. Initially the soils of the selected sowing sites were analyzed for its type and pH before sowing.
The chemical composition of sorghum fodder was determined to assess the nutritive value at different cutting stage of growth in district Okara and Bhakar. Sorghum samples were analyzed for proximate analysis, macro minerals and In-situ digestibility using fistulated animals. The results of present study showed that average dry matter, moisture, crude protein, crude fiber, ether extract, ash, NDF and ADF values from all the cuts of sorghum fodder were 24.29%, 75.56%, 8.5 1%, 28.26%, 2.34%, 7.5%, 62.95%, 61.04%, 38.41%, percent respectively from district Okara and were 23.48%, 76.53%, 7.95%, 27.5 1%, 2.23%, 8.25%, 61.04%, 37.04 percent respectively from district Bhakar. The dry matter, crude fiber, NDF and ADF also increase as plant gets maturity.
The average In-situ digestibility at 24 hrs and 48 hrs from all the cuts of sorghum fodder were 67.53%, 78.5 1% and 67.16%, 77.90% from Okara and Bhakar respectively. In-situ digestibility decreases as fiber increases.
The average Ca, P. Na, K values from all the cuts of sorghum were 0.40%, 0.11%, 0.05%, 1.86% in Okara district and were 0.32%, 0.14%, 0.03%, 2.02% for Bhakar district. The average yield of sorghum fodder was 21.73 t/ha in Okara and was 18.41% in Bhakar districts.
A significant difference was seen in nutritive value of sorghum fodder from all the cuts from Okara and Bhakar districts. This differenc3e might be due to the temperature fluctuations, water availability and soil fertility.
It was concluded that topographically the Okara district is better for growing sorghum fodder.

Publisher: 1990Dissertation note: The cigarette smoke condensate (CSC) and total particulate matter ('1PM) of cigarette smoke is sternly toxic to health and may produce several pathologies. In our study, we have focused on the toxicological effects of CSC and '1PM on different events of angiogenesis using chicken chorioallantoic membrane assay (CAM). CSC and 1PM from four different commercial filtered cigarettes were applied to the CAMs on day 4 of incubation. Macroscopic vascular transformations were evidently observed among all treated CAMs. Applications of CSC disk caused sturdy obliteration of main blood vessels, while whole architecture of the secondary and tertiary vasculalure was completely destroyed. Likewise, application of '1PM from all brands of cigarette caused disproportionate thinning of all primary and secondary blood vessels. Reduction in the total area and diameter of primary, secondary and tertiary blood vessels were observed after treatment with CSC and TPM. 1-listological evaluations revealed loss of ectodermal and mesodermal integrity in botl'i types of treatments. Scanty capillary plexuses formation, deterioration of extracellular matrix and delayed migration of blood vessels were prominent findings among all treated groups. Results obtained from CSC treated groups were more localized, while generalized results were prominently recorded in 1PM treated groups. Special considerations of CSC and 1PM should he given while smoking during pregnancy and after surgery because it may severely affect the process of angiogenesis, which is vital in maintenance of pregnancy and wound healing.

Publisher: 2011Dissertation note: There has been a gradual decline in per capita availability of proteinous food particularly of animal origin for human consumption in our country. The feasible solution of the problem is to increase the production of meat. The potential of buffalo as a food animal to meet present and future demands of rapidly growing population deserves special attention because of its capacity to economically convert course roughages and other cereal by products into meat.
Pakistan is second largest buffalo holding country in the world having 29 million buffalo. Traditional system of buffalo meat production is inefficient; animals destined for slaughter are mostly culled and old stock. Male calves are not reared specifically for producing meat but they are kept only for milk let down in villages and are slaughtered even at 6-7 days of age in pen-urban areas. So far very little work has been done to evaluate the tremendous meat production potential of buffalo calves with a particular plan of nutrition.
Present study consisted of a feeding trial of about three months in duration. Fifteen Nih Ravi calves of approximately the same age and weight were selected for the subject study. The animals were randomly divided into three equal groups which were reared on three different feeding regimes. Group I was fed TMR ad-libitum and 2 kg of green fodder. Group II was fed available green fodder ad-libitum and concentrate ration
@ 1% of body weight. Group III was fed Lucerne hay ad-libitum and concentrate ration @ 1% of body weight. . Weighed quantity of feed was offer to every animal on individual feeding basis in a group and refusal was also recorded individually.
The results of study revealed that animals fed on TMBR performed better as compared to other feeding regimes. Among three feeding groups, highest (124.60 ± 7.82 kg) weight gain was observed in TMBR group while, lowest (108.20 + 5.80 kg) weight gain was found in Hay group. As far as feed intake is concerned, highest (777.42 + 8.87 kg) feed intake was observed in fodder group while, lowest (755.10 ± 16.61 kg) feed intake was found in TMBR group. Out of three feeding groups, calves fed on TMBR showed best feed conversion ratio (6.07 ± 0.47) while, the feed conversion ratio in calves fed on hay and fodder was 7.04 ± 0.39 and 7.01 ± 0.32 respectively. Economic analysis per kg weight gain revealed that TMBR group had the lowest cost of production in rupees (101.43 ± 7.92) per kg weight gain, where as highest cost of production (130.40± 7.40) was found in hay group. Analysis of variance of serum chemistry means revealed that no significant differences were found in total protein, urea, glucose, and creatinine values for all three feeding regimes.
On the basis of results of this study it is concluded that TMBR can be utilized as an alternate for our conventional feeding practices as it can meet all nutritional requirements of the animal. It is easy to handle, transport and store besides having a longer shelf life.
It is suggested that further trials with TMBR be carried out on different age and sex groups of buffalo and cattle in order to evaluate its effects on the performance of the animals.

Publisher: 2011Dissertation note: Buffalo is an important animal which contributes approximately 50% meat in Pakistan. Traditional system of meat production is inefficient. About 50 % of the male calves die during the first week of their life. Some calves are raised to 60-80 kg on extremely poor and unbalanced diets and only a few are raised to about 200 kg of live weight with very low average daily gains. Most of the meat produced in the country comes from end of career, or emergency slaughtered animals. To improve meat production in country calves are required to be fattened through feed lot system. Energy-rich sources available in Pakistan include cereal grains (wheat, maize, barley, oats, sorghum, and rice), wheat bran, rice polishing and molasses etc. At the same time fats and oils are also rich source of energy and infrequently used in animal feeding. Molasses, a by product of sugar industry, is an excellent and cheaper source of energy. An objective of the study was to compare efficiency of energy sources for meat production. For this purpose, a fattening trial was conducted on 15 Nili-Ravi buffalo calves of approximately the same age and weight to study the comparative efficacy of three different energy rations. Animals were divided into 3 groups of 5 calves each. Animals were offered three different rations. The experiment was carried out for 90 days. Group A was fed TMR having molasses as energy source, group B was fed TMR having com grain as energy source and group C was fed TMR with rumen protected fat as energy source. Daily feed consumption, body weight gain, feed conversion ratio, economics and blood parameters (blood glucose, total protein, urea and creatinin) were studied. The Data obtained was analyzed under CRD through ANOV A and the difference among treatment means were tested with LSD. The average weekly growth rate of group A, B and C was 6.23±0.187, 6.l85±O.l87 and 6.08±0.187 respectively. The average daily growth rate of group A, Band C was 0.89, 0.88 and 0.87 kg respectively. Total Mixed Ration taken by group A, B and C was 2064.5 kg, 2546.01 and 1993.7 kg respectively. The average daily feed intake was 4.59 ±O.l06, 5.66±0.106 and 4.43±0.106 kg per day of group A, B and C respectively. Group A, C had non significant difference (P>0.05) from each other while group B was significantly different from group A and C. The feed conversion ratio of group A, B and C was 5.16 ±0.25, 6.40±0.25 and 5.10±0.25 respectively. The results showed that calves fed ration C has highest FCR than ration A and B. The results of the study revealed non significant difference in the concentration of serum urea, creatinine, glucose and serum total protein among the experimental animals. The cost of one kg live weight for group A was Rs 78.73 while Rs 102.78 and Rs 129.1 for group Band C. The results showed th~t ration A was more economical than ration Band C. The findings of this study showed the benefit of utilization of different energy sources in the fattening ration of calves. Due to higher prices and demand of cereal grains, other cheaper sources such as molasses can be used for fattening as energy source. If there is unavailability of molasses and cereal grains then bypass fat (Berga fat) can be used for fattening purpose. The study revealed that each energy sources is equally effective.

; Nature of contents: ; Literary form: Publisher: 2011Dissertation note: Livestock is contributing about 53 per cent of agricultural value added and 11.4 per cent to the national GDP with a total animal heads of 157.3 million but feed availability of crude protein (CP) and total digestible nutrients (TDN) is deficient by 38.10 and 24.02%, respectively. However, a decline in domestic feed resources and the need for Pakistan's livestock production to become internationally competitive are strong reasons for promoting the use of alternative locally available and cheap sources of feed ingredients, such as citrus pulp from fruit processing industry which do not attract competition in consumption between humans and livestock. The primary objective for the use of these by-products is to reduce the feed cost and consequently cost of producing a unit of the product like milk or meat as well as to fulfill the nutrients demands of animals. Citrus pulp is a by-product widely available in Pakistan and is mainly discarded as waste. Its cost is relatively low compared to its nutritive value but is seldom used as ruminant feed. The large amounts which are available during the harvesting season can be ensiled in combination with dry roughage, to get the required moisture level of it. So in the present study citrus pulp with wheat straw was ensiled and the silage was fed to Sahiwal calves to observe its intake, weight gain as well as economics. Results of the present study revealed that the optimum level of 20% citrus pulp in feed gave good results while intake and weight gain decreased for 30% citrus pulp in feed. Average total weight gain were 27.5, 37.5, 28.75 and 23.75kg for ration A, B, C and D, respectively (containing 10, 20 and 30 citrus pulp, respectively). Average daily gain for group A, B, C and D were 0.44, 0.60, 0.46 and 0.38kg, respectively and the difference was statistically significant (P < 0.05). When average daily feed intake for each calf was calculated on dry matter basis it showed 4.40, 4.50, 3.39 and 3.13kg respectively for group A, B, C and D which was not significantly different between diets. By ascertaining the cost of the feed for ration groups it showed significance difference having average cost of production per animal per kg body weight 37.07, 23.80, 21.68 and 25.58 Rs for group A, B, C and D, respectively.

Publisher: 2010Dissertation note: The production of single cell protein on agricultural wastes is amongst the potential non-conventional protein source for humans in protein deficient countries like Pakistan. Microorganisms in single cell protein have high protein contents and short growth times which lead to rapid biomass production. Moreover, microorganisms are able to utilize cheap sources of nitrogen and abundant carbon sources. Thus, the resulting biomass is usually economical having high potential as a supplement as well as protein fortificant to provide balanced nutrition.
The peels used for yeast biomass production study resulted in variable composition. Orange peel contained significantly highest (38.66 %) moisture content as compared to other peels. Regarding dry matter, the maximum DM (80.66 %) was present in potato peels while, crude protein contents were higher (10.13 %) in orange peels. In biomass production, the maximum growth (5.29 %) of Saccharomyces cerevisiae was obtained on potato peels while, lowest growth (0.3 %) of Saccharomyces cerevisiae was observed on apple peels. Both apple and potato peels nitrogen free extract were statistically non-significant.
Proximate composition of experimentally produced yeast biomass was comparable with commercial yeast. Biological evaluation of single cell protein (SCP) diet in Sprague Dawley rats was conducted and compared with casein diet to determine the SCP protein quality. The values for SCP protein quality for parameters of TD, NPU, BV, NPR, FER and PER were 93.68 %, 67.02 %, 70.56 %, 4.55 %, 3.62 % and 2.19 % respectively, which were significantly lower as compared to casein diet. Although the scores for biological parameters of SCP diet were lower as compared to casein diet, yet the differences in actual values for both the diets was not much which indicates the overall good quality of SCP protein.
SCP also showed excellent water holding capacity (303.40±0.30 %) and oil absorption capacity (196.50±0.20 %). Similarly, foaming capacity, loose bulk density and packed bulk density were observed as 10.60±0.20 %, 0.65±0.01 % and 0.66±0.01 %, respectively. It also showed good gelling capacity as 0.7 g/20mL of yeast biomass resulted in complete gelling of the solution.
Yeast was used to fortify flour at various concentrations to prepare and evaluate protein enriched sugar-snap-cookies. The cookies, thus prepared, were subjected to physical and sensory evaluation to find out the most appropriate level of SCP fortification for cookies development. The spread factor and diameter of cookies decreased while cookie thickness increased with SCP fortification. There was not much difference in most sensory scores attributed to all fortified cookies with the exception of texture and taste which deteriorated with fortification. Although taste and texture scores were less yet the cookies fortified with up to 4% of SCP were well in high acceptable limit.
In a nutshell, potato peels can serve as a good vehicle for production of single cell proteins. Experimentally produced yeast was chemically comparable with that of commercial yeast; however its growth production varies with carbohydrates present in the industrial waste peels. The overall protein quality of SCP protein was found to be very good and thus can be used in various food formulations to enhance protein quantity and quality. Cookies fortified with up to 4% SCP were found to highly acceptable and thus recommended for fortification.

Publisher: 2011Dissertation note: There are certain growth promoters like antibiotics, probiotics, prebiotics and organic
acids etc. which can improve feed efficiency in chickens. The use of antibiotics as growth
promoter creates a huge problem for environmental conditions and health of consumers around the world. The use of organic acids as acidifiers is recommended as an alternative to antibiotics to control certain types of acid intolerance bacteria and growth-promoting agents in poultry production. Many studies have been done to study the effects of organic acids on performance of broilers and layers; however, little research has been conducted to study the impact of these growth promoters on quail growth performance. This study was planned to test the effect of organic acid acidifiers i.e. Salkil®® and Sal Curb Dry® on the quail production performance and their effect on blood calcium, phosphorus, cholesterol and quail carcass traits at Avian Research and Training Centre, Lahore. The analysis of feed, blood and meat was performed in laboratory of Department of Food and Nutrition, University of Veterinary and Animal Sciences, Lahore. One standard (control) quail feed will be prepared (NRC 1994). Two different levels each of Salkil® acidifier i.e. 1 g/kg and 2g/kg of feed and of Sal Curb Dry® acidifier i.e. 1 g/kg and 2g/kg was incorporated in the standard feed to prepare five experimental feeds. A total number of 400 un sexed day old quail chicks were equally divided into five groups having 80 chicks in each group with four replicates having twenty chicks each. The group offered standard feed has served as control. The rest four experimental feeds with two different levels of SaIki!'!!) and with two different levels of Sal Curb Dry® were allotted to four different groups. At the end of
experimental trial which was of 28 days body weight, feed consumption, feed
conversion ratio, giblet weight, serum calcium and phosphorus, carcass traits ( analyzed for
meat moisture %, crude protein % and crude fat %) and blood cholesterol level was analyzed. To test the blood cholesterol level, two birds from each replicate were taken at random and blood samples were collected in heparinzed vacutainers from jugular vein after slaughtering. Dressing percentage was also recorded along with economics value of quail meat. The values of weight gain in group A, B, C, D, E and F was found 140.783 ±6.24,
147.5Sbc ±3.45, 151.56c ±4.84, 143.92ab± 4.98 and 147.88bc ±5.17 respectively .. The group C which was fed Salkil® 2g/kg of feed showed maximum weight gain followed by group E, B, D and A respectively. When the data was statistically analyzed on weekly basis there was non- significant (p>0.05) difference among different treatments groups except at second week. The values of feed conversion ratio in all the five groups were 2.859b ±O.l3. 2.769ab ±O.l90, 2.734a ±O.12, 2.S17ab ±0.093 and 2.772ab ±0.14 respectively. The treatment groups which received the acidifiers significantly (p<0.05) improved the FCR. The values for giblet weight in the above mentioned groups were 9.l7a±0.58, 9.25a ±0.33, 9.44a ±0.26, 9.23a ±0.41 and 9.45a ±0.51 gm respectively. The values for calcium were found to be 10.98a±1.01, 11.33a±0.62, 10.33a±0.S7, lO.95a±1.13 and 11.22a±1.39 mg/dl respectively while for Phosphorous 5.01 a ±0.37, 4.99a ±0.71. 5.2Sa ±0.49, 5.0Sa± O.SI and 5.21 a ±0.21 mg/dl respectively. The values for serum cholesterol
level in the five groups 130c ±5.00, 125bc ±6.00, 113a ±6.00, 127bc ±7.00 and 121 b ±7.27 rng/dl respectively. Serum cholesterol level in group A is significantly higher. The average meat moisture. crude protein did not differ significantly but use acidifiers significantly decreased the fat deposition in meat.

Publisher: 2011Dissertation note: Prebiotics (including galacto-oligosaccharides) are regarded as non-digestible food ingredient that beneficially affects the host by selectively stimulating the growth and/or activity of one or a limited number of bacteria in the colon, and thus improve host health. They impart several important physiological effects depending on the composition and/or balance and activities of beneficial microflora i.e. Bifidobacterium and Lactobacillus. Recent findings propose that mal-nutrition and its synergistic relationship with preventable infectious diseases causes 21% deaths around the globe and disability adjusted life years in children's below five years of age. Children who are fed on infant formula are more susceptible to infectious diseases than breast fed children. Keeping in view the need for the improvement of child health through improving the immunity, the present research project was designed. The study was conducted in three different phases. In the first phase, characterization of galacto-oligosaccharides (GOS) was done. During the second phase blending of oligomate with all-purpose wheat flour at 12, 24, 36 and 48% (w/w) levels were done to prepare prebiotic fortified-wheat-flour cookies at 1, 2, 3 and 4 %. The cookies thus prepared were physically and organoleptically evaluated for the selection of optimum level of prebiotic fortification and the best treatment selected along with control was used for efficacy studies. During third stage, efficacy of GOS fortified cookies were evaluated on selected normal 2-5 years young children. During efficacy study 40 healthy children were recruited and divided into two groups. First group was taken as control and was given unfortified cookies whereas second group was given galacto-oligosaccharides fortified 8 cookies per day. Each individual subject was given GOS for 40 days. Urine and stool samples were collected at 0, 20 and 40 days of study for analysis. Weekly follow-up visits were scheduled and consisted of a detailed physical examination and other health and diet related information through pre-structured interviews and body measurements. The data obtained was statistically analyzed to check statistical significance and to compare means. Significant results were obtained for physical and chemical properties of oligomate. Physical and chemical analysis of cookies also showed significant results however within the treatment non-significant results were observed as well as the storage study also showed non-significant results. The analysis of variance shows the mean squares for colony forming units. The mean squares (2.53) and p-value (0.014*) for groups on various diets showed significant results. However, Mean squares for interval and the interaction between groups and study interval showed non-significant
The means show significant results for groups with respect to study interval. The highest mean value is seen for fortified cookies (8.48a) showing that the colony forming units have been significantly increased and the lowest was seen for control group (7.82c) in which opposite results were seen that is the colony forming units decreased instead of increasing. These results were in line with the study of Piirainen et al. (2008) who evaluated the effects of galacto-oligosaccharide.

; Nature of contents: Publisher: 2011Dissertation note: Genetics of prolificacy in sheep and goat emphasize the importance of main genes which have been made known to affect litter size and rate of ovulation through various mechanisms. Natural mutations in prolific sheep and goat breeds have shown that the transforming growth factor beta (TGF-?) super family ligands such as bone morphogenetic protein 15 is crucial for ovulation and as well as for increasing litter size. Keeping in view the importance of prolificacy in sheep and goat, a research project was planed to identify the polymorphism, its association with fecundity and uncovering the nucleotide picture of BMP15 fecundity gene in sheep and goat breeds of Pakistan. In the research finding, various polymorphism, insertion and deletion of nucleotides in goat and sheep breeds of Pakistan were identified and associated with fecundity and secondly, some novel polymorphism in Pakistani goat and sheep breeds were identified which are different from the goat and sheep breeds of the world. This is the first report of the whole nucleotide of BMP15 gene in the sheep. A lot of work has been reported on these genes but total nucleotide picture in the sheep is not reported. Sequences of Bmp15 gene from sheep and goat breeds of Pakistan has been submitted to the NCBI GenBank database libraries,USA under accession numbers JN655669, JN655670, JN655671 and JN655672. It will result in fast vertical expansion of small ruminants to increase the mutton production and uplift the socio economic condition of small ruminant's farmers in the country.

Publisher: 2012Dissertation note: Fodder and forage production in Pakistan is seasonal and this leads to erratic supply of feedstuffs to the animals. After a rich legume season, a depression period occurs, which is replaced by non-legume forages and followed again by a scarce fodder supply season. These changes in the forage supply have unfavorable effect on livestock performance. The key solution to this problem is the conservation of forages for the time, when there is feed scarcity. Keeping in view the existing availability of green fodders and silage additive products, the methods of developing alternative means to ensure availability of quality feed to animals having high nutritive value.
The Experiment was carried out at Livestock Production Research Institute, (LPRI), Bahadurnagar, Okara. Two types of corn silages were prepared, one was be untreated corn silage (Control as diet-b) and other corn silage was treated with inoculants; a commercial product "Sil-All" by ALL-TECH, (diet-a). Eighteen healthy lactating Sahiwal cows at the same milking stage were randomly distributed to two groups A and B (9 each) and were fed individually. Data was collected during the feeding experiment of 60 days duration on feed intake, daily milk production, milk composition, silage composition and body weight gain. Sahiwal cows belonging to all groups were offered concentrate according to milk production @ 1 Kg for each 3 liter of milk produced. Milk samples were analyzed for Lactose, Fat, SNF and Protein using "Milk-O-Scan" in the Dairy Laboratory of LPRI, Bahadurnagar, Okara. The feed samples were analyzed in the laboratory for Dry Matter, Crude Protein, Ether Extract, Crude Fiber, ADF, NDF and Ash contents. The data thus obtained was analyzed through Paired Sample T-test.
Daily silage intake in Sahiwal cows was 30.12±0.601 and 26.29±0.614 kg fed on inoculated silage and untreated corn silage, respectively. Inoculated silage intake was higher (P < 0.05) in Sahiwal lactating cows than cows on untreated corn silage. Milk production was higher in cows of group A fed with inoculated Silage. The results showed that Sahiwal cows fed on inoculated corn silage and untreated (control) corn silage produced 6.11±0.40 and 5.94±0.28 liters milk daily, respectively. It is also evident from the data that the cows on inoculated silage diet produced milk significantly higher (P < 0.05) than the cows under control.
Mean milk fat contents were 5.65±0.11 and 4.95±0.03 % in the milk of Sahiwal cattle fed on inoculated and untreated corn silage diets, respectively. The results showed that the cows under inoculated silage feeding produced significantly more milk fat than the cows under control. Higher (P < 0.05) milk fat contents were recorded in cows on inoculated silage than on control. Mean milk protein in the milk of Sahiwal cows fed on inoculated and untreated corn silage were 3.11±0.02 and 2.85±0.05 %, respectively. Lactose content were also higher (4.62±0.04 %) in cows on treated corn silage diet as compared to cows on control diet (4.22±0.03 %). Significantly higher (P < 0.05) solids not fat contents were recorded in cows on inoculated silage diet than the cows on untreated corn silage diet (7.72±0.14 %).
Sahiwal cows given inoculated corn silage diet had higher (329.09±5.028 kg) body weight than the cows under control (322.96±5.08 kg). A non-significant difference (P>0.05) was observed among treatment. Sahiwal cows showed a fortnightly weight gain of 01.029±0.017 and 00.712±0.010 Kg per cow fed on inoculated and untreated corn silage, respectively.
Silage pH was also improved in the diet containing inoculated silage (3.90±0.05) than the untreated silage showing a pH level at 4.08±0.35 in the untreated corn silage, showed non-significant difference (P>0.05).Dry matter contents in the inoculated corn silage had higher (30.40±0.60 %) DM % while untreated corn silage had the lowest (28.14± 0.84 %), statistically significant (P < 0.05). Mean crude protein level was 6.27±0.33 and 5.39±0.28 % in the diets having inoculated corn silage and untreated silage, respectively.
Highest value (9.17±0.75 %) of Ether Extract was recorded in inoculated corn silage diet, while untreated silage diet showed lowest (7.69± 0.24 %) value, and significant difference (P <0.05) was observed. Inoculated corn silage diet had highest (25.17±0.35 %) crude fiber level, while untreated corn silage diet showed lowest (24.51±24.51 %) crude fiber level. Inoculated silage diet had the highest (53.41±0.79 %) NDF, while untreated silage diet showed the lowest (49.34± 0.58 %) feed NDF. A significant difference (P<0.05) was observed in the inoculated diet as compared to untreated silage. The inoculated silage diet had the highest (30.23±1.00 %) ADF, while untreated silage diet had the lowest (28.26± 0.63 %) level showed a significant difference (P<0.05).The diet untreated had the highest (9.16±0.82 %) ash level while the level of Ash contents was lowest (7.69± 0.24 %) in the inoculated diet.
The results of the trial indicated significantly higher daily intake and increased milk production in Sahiwal cows was recorded when fed on inoculated silage diets. Milk constituent (Fat, Protein, Lactose and SNF) were also improved significantly in cows under inoculated corn silage diets. Sahiwal cows given inoculated corn silage diet had higher body weight than the cows under control. The composition of inoculated silage diet (DM, CF, NDF, ADF and Ash %) was also improved significantly as compared to untreated silage diet. On the basis of results presented in the study it is concluded that the use of additive or inoculant like Sill-All can be used to enhance milk production and overall performance of dairy cows.

Publisher: 2013Dissertation note: Poultry is the second largest industry of Pakistan and a significant proportion of poultry products (meat and eggs) originates from the rural poultry production system which is an important source of livelihood for about 80% of the rural households in Pakistan. The quest for greater production through the use of exotic breeds has created difficulties for backyard production systems and is dangerous on economic, social and scientific grounds. This practice is also resulting in rapid erosion of indigenous genetic resources.
The commercial sector itself may require access to indigenous genotypes as its genetic base is quite narrow and for catering the future needs industry may require improvement in many other characteristics (for instance, adaptability and disease resistance) in addition to just egg and meat yield enhancement. Unfortunately, in many countries the indigenous breeds have not been studied for their potential uses and benefits and have been indiscriminately cross bred with exotic breeds. Therefore, it is crucial to study and characterize the indigenous breeds and generate necessary information to be used in future to reap maximum benefits. The generated knowledge would provide useful information essential for conservation of indigenous genetic resources.
The knowledge about the morphological attributes of native chickens has not been adequately documented on technical and scientific grounds. Keeping this in view the present study was planned and data on qualitative and quantitative traits regarding the morphology were collected on Aseel and Naked-neck chickens using a specially designed performa.All recorded data were entered in MS Excel 2010 spreadsheets. The qualitative parameters were expressed as percentages and quantitative parameters were expressed as mean ± standard error.
A great variation in plumage colors and patterns was observed in both Aseel and Naked-neck chickens. The Aseel chickens possessed a pea comb whereas Naked-neck chickens possessed single comb. Also it was interesting to note that about 10% of Aseel hens possessed spurs however spurs were absent in Naked-neck females. On the basis of quantitative traits,it was found that the Naked neck chickens were smaller in size than the Aseel chickens regarding body weight (Aseel: 1938.7±36.9 g in females and 2317±98.4 g in males; Naked neck: 1160.4±19.3 g in females and 1415±22.2 in males), shank length (Aseel: 8.1±0.1 cm in females and 10.3±0.1 cm in males; Naked neck: 7.5±0.05 cm in females and 8.6±0.1 cm in males), shank circumference (Aseel: 44.2±0.5 mm in females and 52.4±1.1 mm in males; Naked neck: 36.5±0.7 mm in females and 41.4±0.5 mm in males), and keel length (Aseel: 15.1±0.1 cm in females and 16.0±0.2 cm in males; Naked-neck: 14.1±0.2 cm in females and 14.7±0.1 cm in males).
The information about indigenous Aseel and Naked-neck chickens documented in the present study can be used as reference in future for conservation and breed improvement programs.

Publisher: 2013Dissertation note: Fungus is an important concern in poultry feeds because it can grow at any level of their production right from when grains are in field until the finished product is transported and stored. Therefore it is an immense need to protect raw feedstuff as well as finished feed from the attack of fungus. Aflatoxin is one of the toxins produced by fungi and it causes morbidity and mortality in poultry. In the past different compounds have been employed in order to chelate toxins produced by different types of fungi. Humic acid is produced during the normal decaying process by fermentation of organic materials particularly the plants. Humic acid as a toxin binder is a recent advancement that have got the potential to bind aflatoxins produced by A. flavis and A. Parasiticus. The present study was conducted in order to evaluate efficacy of humic acid to chelate aflatoxin B1.
The study was completed in two phases. In first phase aflatoxin B1 was produced while in second phase the toxin thus produced was employed through feed to commercial broiler chicks. A total of 450 birds were used in five different treatments including positive and negative control. There were 90 birds in each treatment and each treatment was comprised of three replicates of 10 birds in each. In positive control three levels of aflatoxin B1 including 100 ppb, 200 ppb and 300 ppb were added into rations without addition of humic acid. In negative control plain feed was offered without supplementation of humic acid and aflatoxin B1. In rest of three treatments different levels of humic acid including 0.1 percent, 0.2 percent and 0.3 percent were used through feed against three levels of aflatoxin B1 including 100 ppb, 200 ppb and 300 ppb. The parameters including feed intake, body weight gain, feed efficiency, giblet weight, keel length, shank length, dressing percentage, tibial toe ash, gross lesions on carcass, mortality and AFB1 concentrations in serum and liver extracts were studied. The experiment was planned under completely Randomized design with factorial arrangement. The data thus collected on different parameters were subjected to statistical analysis through analysis of variance (ANOVA) technique. The difference among treatment means were compared through Duncan's Multiple Range (DMR) Test at P?0.05.
During first week, birds in all experimental groups showed non-significant difference in terms of feed intake, weight gain and FCR as all the birds in different treatments received plain feed without supplementation of either humic acid or aflatoxin B1. During second week, feed intake, weight gain and FCR were minimum in control group consuming different levels of aflatoxin B1 only, while it was maximum among the birds in group 'B' consuming only plain feed with a non-significant difference in the birds receiving different levels of humic acid. It was observed that with increasing level of humic acid feed intake, weight gain and feed efficiency were linearly improved. Similar pattern was observed in terms of the parameters under discussion during 2nd to 4th week. While during last two weeks of experiment all of the birds in different experimental groups were again put on plain feed without supplementation of aflatoxin or humic acid. During this time period the birds in positive control that had consumed different levels of aflatoxin B1 showed variable levels of improvement in terms of feed intake, weight gain and FCR. Non-significant difference (at P?0.05) was observed among the birds consuming different levels of humic acid as compared to control group consuming plain diet.
Mortalities were maximum in groups 'AD', 'BD' and 'CD' with the highest in 'CD' consuming 300 ppb of AFB1. Dressing percentage was best in 'AK3' and followed to BK2, B, BK1 and CK3. This showed growth stimulant activity of humic acid in addition to anti-AFB1 activity.
Results of giblet weight showed non-significant difference among different groups under study except positive control consuming AFB1. Maximum values were observed in groups 'B' and 'CK3' followed by 'AK2' and 'CK3' while minimum was observed in group 'CD'. Results of heart weight were non-significant among different experimental treatments except 'CD' consuming 300 ppb of AFB1. Results regarding liver weight showed significant difference among the birds in positive control consuming different levels of AFB1. Maximum liver weight was observed in group 'CD' consuming 300 ppb of AFB1. During last two weeks when all of the birds were receiving only plain diet again as withdrawal strategy, the birds in positive control that had consumed purified AFB1 during 2nd to 4th week, showed a reversal effect by exhibiting improvement in giblet weight.
Results obtained regarding ND titres showed maximum titres in group 'AK2', 'B' and 'BK2' while were minimum among the birds in group 'CD' consuming 300 ppb of AFB1. Results were significant with control group consuming different levels of AFB1. The results during last two weeks showed that the birds in different groups consuming different levels of humic acid and particularly in 'CD' that had consumed 300 ppb of AFB1 only during time period of 2nd to 4th weeks showed a reversal effect in developing ND titres. The difference was non-significant (at P?0.05) with control consuming plain diet only.
During the time period of active intoxication of birds with purified AFB1, the results obtained regarding concentration of AFB1 in liver extracts showed non-significant difference among different groups consuming humic acid while significant as compared to control group 'CD' consuming 300 ppb of AFB1. This demonstrated AFB1 chelating activity of humic acid. The results were also significant as compared to group 'B' consuming plain diet only. Maximum concentration was found in group 'CD' consuming 300 ppb of AFB1. After 28th day until 42 days of experiment all of the groups showed a clearance effect of AFB1
Conclusions:
Findings of the current study revealed that addition of increasing levels of humic acid improved the growth and performance of commercial broiler chicks as compared to control group suggesting its potential role in chelating Aflatoxin B1 challenge of different magnitude when given through feed. Therefore, humic acid is recommended for its use as Aflatoxin B1 binder through feed at an inclusion rate of 0.2% of the ration.
