14. A Study On The Effects Of Different Photperiods On The Performance Of Coturnix Coturnix Japonica (Japanese Quails)

by Khalid Mahmood | Ch Muhammad Saleem | Dr Muhammad Aslam Bhatti | Dr Saghir.

Material type: book Book; Format: print ; Literary form: not fiction Publisher: 1985Dissertation note: The study was aimed to find out the effect of different photoperiods on body weight gain, feed consumption, feed conversion ratio, age at first egg laid, mortality and dressing percentage of Japanese quails (coturnix coturnix Japonica) . The photoperiods provided were natural day light, 6 hours light and 18 hours darkness, 10 hours light and 14 hours darkness and 14 hours light and 10 hours darkness to groups A, B, C and D respectively. One hundred and eighty, one day old quail chicks were divided into four groups comprising 45 birds each. These groups were further sub-divided into three replicates of 15 birds each. They were provided 25 sq. inches floor space per bird and fed ad-libiturn on a ration containing 26% protein throughout the study period of 70 days. Feeding, watering, environmental and manage mental conditions were made identical for all the birds. The average live weight of the quails recorded at the end of the 10th week was 161.25 gms., 134.52 gms., 165.59 gms., and 186.33 gms., with feed consumption of 870, 699, 882, and 1031 gms., for the groups A, B, C and D respectively. A highly significant difference was observed for weight gain among all the groups except groups A and C. For feed consumption a highly significant difference (P/0.0l) was observed in groups B and D while the difference in groups A and D was significant (PL0.05) and no significant difference was noticed in groups A and C, because of almost equal hours of light. The feed conversion ratio was 5.68, 5.53, 5.60 and 5.79 for groups A, B, C and D respectively, and no significant difference was observed among all the groups. The age in days at which the first egg laid was 55, 69, 58 and 51 in groups A, B, C and D respectively. The mortality percentage was 16.00, 33.55, 13.33 and 11.00 and the mean dressing percentages recorded at the end of experiment were 62.5, 63.0, 62.7 and 64.0 for groups A, B, C and D respectively. No significant difference was observed for dressing percentage in all the groups. CONCLUSION From the results of the present study it was concluded that Japanese quails can be reared economically and efficiently under natural day light throughout the year in Punjab for table purpose. It is advisable to market the broiler quails at 6 weeks of age as keeping them longer is uneconomical. However, if the quails are to be kept for breeding purpose, at least 14 hours continuous light per day should be given in order to attain early sexual maturity and onset of egg production. It is suggested that the study should be extended upto two successive generations to assess the productive potential of Japanese quails in detail under local environmental conditions of Pakistan.

by Muhammad Azam Chaudhri | Dr Nisar Ahmad | Dr Muhammad Yaqoob Malik | Mr Muhammad.

Material type: book Book; Format: print ; Literary form: not fiction Publisher: 1989Dissertation note: A research project was undertaken to study the effect of different dietary energy and protein ratios on the performance of broiler chicks. The performance of chicks were studied under the headings of weight gain, feed efficiency, feed consumption, dressing percentage and economics. Four starter rations containing calorie protein ratios of 167, 149, 136 and 123 and four finisher rations containing calorie protein ratios of 199, 178, 159 and 145 were tried on one hundred and twenty day old broiler chicks of both sexes for a period of 50 days. The starter rations were fed up to 28 days of age and remaining 22 days the finisher rations were fed. The results showed that the starter rations containing calorie protein ratios of 136 and finisher ration containing calorie protein ratio of 159 were best in promoting weight gain, feed utilization and were economical as compared to other calories protein ratios. Different calorie protein ratios did not influence the dressing percentage of broiler chicks. It was concluded that careful combinations of energy and protein in poultry feed formulations Availability: Items available for loan: UVAS Library [Call number: 0886,T] (1).

16. Effect Of Light Restriction On Performance Of Baroilers Fed Conventional And Non Conventional and Non Conventional Growth Promoters

by Shafique-ur-Rahman | Dr. Athar Mahmood | Prof.Dr | Dr. Farina Malik Khattak.

Material type: book Book; Format: print ; Literary form: not fiction Publisher: 2006Dissertation note: This study was performed to investigate the effects of light restriction and non conventional growth promoters on growth performance of broilers. For this purpose one hundred and eighty broiler chicks were grown in an open sided house for a period 42 days. Chicks were randomly distributed into four groups (A, B, C and D) each containing five replicates with nine birds each. Groups A and B were reared under continuous light, groups C and D received restricted light of 20 hrs light and 4 hrs dark.. Groups A and C were fed with diet containing conventional growth promoter. Zinc bacitracin at dose rate of 0.5 grams per kilogram of feed was used as a conventional growth promoter. Groups B and D received non conventional growth promoters. Botanical growth promoter 1 (B.G.P 1) was used as non conventional growth promoter dose rate was 1 gram per kilogram of feed. Body weight gain and feed intake was recorded weekly. At the end of the experiment mortality, microbial count and economics of the project was calculated. Data revealed that birds in all groups had non significant (P>0.05) weight gain, feed intake and FCR when compared with each other. Microbial count was higher in groups fed with conventional growth promoters than non conventional growth promoters. Mortality in control group A was highest (8.8%) as compared to group B, C and D which was 4.4. 6.6 and 0% respectively. Rectal temperatures of all treated groups were similar (37oC) to those of control birds. This study clearly indicated that non conventional growth promoter can be used in place of conventional growth promoters and restricted lighting reduces mortality and electricity cost.

17. Comparative Growth Performance Of Different Broilers Strains

by Syed Ansar Hussain Shah Naqvi | Dr.Farina Malik | Prof.Dr.Muhammad Akram | Prof.Dr.Talat.

Material type: book Book; Format: print Publisher: 2007Dissertation note: This present study was performed to investigate the comparative growth performance of different broiler strains. The experimental birds from four different strains viz Arbor acre (AA), Hubbard (RB), Hybro (FlY), and Starbro (ST) were randomly divided into 4 treatment groups each having 14 birds to evaluate the best performing strain under the local environmental condition. All the chicks in each replicate were weighed and placed in individual litter floor pens with the provision of separate feeding and drinking equipment. Ad. Libitum feed and water was offered to the birds in each replicate with the provision of 24hours light. Commercial broiler starter feed was provided from 0-4 weeks and finisher from 5-6 weeks of age. Room temperature and humidity percentage was recorded daily. Body weight, feed intake were recorded weekly. FCR was also calculated on weekly basis. And mortality was recorded as and when occurred. At the end of the experiment two birds' one male and one female from each replicate were randomly selected to study slaughter parameters such as live weight, dressed weight and different organs weight (shank length, head weight, liver weight, gizzard weight, heart weight, intestine weight, intestine length, ceacal weight). The daily temperature range was 24 C to 40 C and the humidity percentage was from 20 to 90 % throughout the experimental period. The overall data showed no significant difference (P<0.05) in weight gain, feed consumption and FCR values of four different broiler strains. However, consistently higher weight gain and feed consumption was observed in birds of strains AA. Where as comparable FCR values were observed in birds of strains AA, RB and HY. However birds in strains SB showed lowest (P>0.05) weight gain and highest FCR. Significant differences (P<0.05) were observed in live weight of male and female birds. Highest (P<0.05) live weight and dressed weight was observed in birds of SB strain. The highest dressing percentage was observed in birds of AA and HY strains. The significant differences (P<0.05) were observed in head weight of female birds from different broiler strains, the head weight of the birds from HB was significantly (P< 0.05) higher compared to lower weight of AA. The significant difference (P<0.05) was observed in shank length of female of the group AA birds. There was no significance difference (P> 0.05) in the liver weight, gizzard weight, intestinal weight, intestinal length, and ceacal weight of birds from different broiler strains. The trial indicated that all the broiler strains such as Arbor acre (AA), Hubbard (RB), Hybro (HY), and Starbro (SB) can be reared profitably and uniformly under our local environmental temperature. It is also evident from the data that each strain has its own peculiar characteristics. AA, I-lB. and MY showed better growth performance, whereas maximum mortality was observed in the birds of SB thus indicating poor resistance to the diseases.

by Muhammad Usman Khan | Dr.Farinea Malik Khattak | Prof.Dr.Muhammad Akram | Prof.Dr.Talat.

Material type: book Book; Format: print Publisher: 2007Dissertation note: Poultry industry of Pakistan contributes a large segment to the national economy with an investment of more than 70 billions of rupees and has become the second largest industry after textile in Pakistan. The present project is designed to study the comparative hatching traits of different broiler strains. There are many commercial poultry companies that rear parent stocks consisting of different broiler parent strains of Hubbard, Hybro, Starbro, Arbor Acres. This sector is presently showing an annual growth rate of about 10-15 percent per annum and playing a vital role in narrowing down the gap between supply and requirement of animal protein foods. The present project is designed to study the comparative hatching traits of different broiler strains Hubbard, Hybro, Starbro, Arbor Acres. A total of 600 eggs comprising 150 each of the 4 broiler breeder strains viz. Hubbard, Hybro, Starbro and Arbor acres were purchased from local companies maintaining parent breeder flocks. These eggs were divided into three replicates having 50 eggs of each. All the eggs were examined on the basis of their size, shape and shell texture for the selection of settable eggs in each replicate. All eggs were weighed and coded and 3 eggs from each replicate were taken for measuring the egg quality characteristics before setting in the setter part of the incubator for the first 18 days. On day 19 all eggs were transferred to the hatcher room. Prior to shift eggs to the hatcher, all eggs were candled to check the fertility. Chicks were collected after 21 days from hatcher. The parameter such as, egg Weight, shell weight, shell thickness, albumen Weight, albumen height, yolk colour, yolk height, yolk diameter, yolk weight, yolk index, meat spot, blood spot, hatchability percentage, chick weight, infertility percentage, dead in germ percentage, dead in shell percentage were studied. The result of present study showed that, the mean egg weight indicated significant differences among different broiler strains. The maximum mean egg weight was recorded in Hubbard strain (68.5 gm ± 4.7).The mean shell weight showed significant difference among different broiler strains. The mean shell thickness showed non-significant difference among different broiler strains. The mean yolk colour, yolk diameter, yolk weight showed significant difference (p<O.O5) among four different broiler strains. The mean yolk height and yolk index showed non-significant difference (P>0.05) among different strains. The mean albumen weight and albumin height indicated significant difference (P<0.05) among four different broiler strains. The meat spot percentage showed that the significantly increased (P<0.05) number of meat spots were observed in eggs obtained from Hubbard strain (1.33 ±4.6) compared to all of other strains. The blood spot percentage significantly (P<0.05) higher number were recorded in starbro strain (1.98 ± 0.56) as compared to all other strains. The hatchability percentage of Hubbard strain (71.63 ± 5.71) was significantly (P<0.05) higher compared to Arbor Acre strain (39.71± 4.91) and Hybro strain (33.57+ 6.22) and the hatchability percentage of Hubbard strain (71.63 ± 5.71) and Starbro strain (68.30± 7.21) were with in same ranges. The mean chick weight indicated significant difference (P<0.05) among different broiler strains. The significantly highest (P<0.05) chick weight was recorded in Hubbard strain (45.17±4.6) as compared to all other strains. The infertility percentage of Hybro strain (1.77±0.20) and Arbor Acre strain (3 9.33±5.42) were significantly (P<0.05) higher compared to infertility percentage of Hubbard strain (14.66±6.67) and Starbro strain (24.50 ±4.26).The dead in shell and dead in germ percentage showed significant difference (P<0.05) among four different broiler strains Based on the finding of this study it may be concluded that the egg quality characteristics like egg weight, shell weight, yolk colour, yolk weight, yolk diameter, albumin weight, albumin height, meat and blood spot percentage have significant differences among different broiler strains. The shell thickness, yolk index, yolk height non-significant difference among four different broiler strains. The Hubbard strain had maximum egg weight, yolk weight, yolk height, albumen height, in comparison to all other three strains. The results with regard to Hatchability traits like chick weight, hatchability percentage, infertility percentage, dead in germ percentage, dead in shell percentage have significant difference among different broiler strains. The Hubbard strain had maximum hatchability percentage and chick weight in comparison to all other three strains. On the basis of this study it may concluded that Hubbard strain have better results as compared to Arbor Acre, Hybro, Starbro strains.

19. Effect Of Vitamin E And Selenium Supplementation On The Performance, Carcass Characteristics And Immune Response in Broilers

by Syed Kaleem -Ul- Hassan | Dr.Abdul Waheed Sahota | Prof. Dr.Muhammad Akram.

Material type: book Book; Format: print Publisher: 2007Dissertation note: The present study was conducted to examine the effect of vitamin E and selenium supplementation on the performance, carcass characteristics and immune response in broilers. For this purpose, 400 commercial day old broiler chicks of Hubbard strain were purchased from a reputed local hatchery. They were maintained in experimental poultry house, Department of Poultry Production, University of Veterinary and Animal Sciences, Lahore during the month of July & August. The chicks were randomly divided into 4 equal experimental groups viz. without supplementation, selenium supplemented, vitamin E supplemented and vitamin E+selenium supplemented, each comprising 100 chicks. The chicks in each group were further randomly sub-divided into 10 replicates of 10 chicks each. All the experimental chicks were initially weighed and individually tagged for identification and kept in 40 pens (10 birds/pen) on littered floor under optimal managemental conditions. The experimental birds were protected against Newcastle Disease through prophylactic vaccination at the age of 4 days (Intraocular route) and then at 21 days (drinking water). Prophylactic vaccination against Infectious Bursal Disease was also performed at 14 and 28 days through drinking water. The birds were given selenium (3mg/kg feed), vitamin E (200 mg/kg feed) and vitamin E+selenium (lcc/10L drinking water) in selenium supplemented, vitamin E supplemented and vitamin E+selenium supplemented groups, respectively, and those in without supplementation were maintained as non-supplemented group. Body weight gain and feed intake were recorded weekly to calculate the Feed Conversion Ratio. At the end of experiment mortality, carcass characteristics, anti-NDV titre were recorded and economics of the project was calculated. The results of this study indicated significant (P<0.05) differences in feed intake and feed conversion ratio due to supplementation with selenium and vitamin E, however, a non-significant effect on body weight gain of broilers was observed due to supplementation. The feed intake in group without supplementation was significantly (P<0.05) different from all other groups, however, non-significant difference was observed in feed intake of groups selenium supplemented, vitamin E supplemented and vitamin E+selenium supplemented. FCR in group without supplementation was significantly poor than those of other groups, however, non-significant difference in FCR of groups selenium supplemented, vitamin E supplemented and vitamin E+selenium supplemented was observed. Results obtained from the study showed significant (P<0.05) differences on carcass characteristics i.e. liver weight and bursa weight, however, non-significant difference in dressing percentage, shank length, keel length, gizzard weight, heart weight, spleen weight and bursa of fabricious diameter due to supplementation of selenium and vitamin E was observed. Statistically significant (P<0.05) difference was found in liver weight of broilers between without supplemented and supplemented groups. The liver weight in group selenium supplemented was significantly greater from group without supplementation, however, non-significant difference was observed in liver weight of groups without supplementation, vitamin E supplemented and vitamin E+selenium supplemented. The bursa weight of the birds in group vitamin E+selenium supplemented was significantly lower from all groups, however, non-significant differences were observed among the birds in groups without supplementation, selenium supplemented and vitamin E supplemented. The results in respect of antibody titres against New castle disease virus vaccine showed that the groups supplemented either with selenium and vitamin E alone or in combination through feed or drinking water gave higher anti-NDV titre than un-supplemented group. The values obtained were 5.30, 6.77, 7.06 and 7.80 for without supplementation, selenium supplemented, vitamin E supplemented and vitamin E+selenium (D), respectively. The economics of production of broilers in different experimental groups indicated that average cost of production remained RS 91.86, 88.21,86.84 and 87.61 in groups without supplementation (A), selenium supplemented (B), vitamin E supplemented (C) and vitamin E+selenium supplemented (D), respectively, showing a higher cost of production in groups B, C and D by RS 3.65, 5.02 and 4.25, respectively in comparison to the control group on account of additional cost of supplementation with selenium, vitamin E and vitamin E+selenium, respectively. The average return came out to be RS 102.042, 104.304, 104.034 and 103.20 in groups A, B, C and D, respectively, and this variation was due to difference in cost of feed intake and weight gain of broilers in different groups. The average profit per bird in groups A, B, C and D was found to be RS 10.182, 16.094, 17.195 and RS 15.586, respectively, indicating a higher margin of profit in groups B, C and D by RS 5.912, 7.013 and 5.404, respectively, in comparison to the control group. CONCLUSION Based on the findings of this study it may be stated that dietary supplementation of selenium (3 mg/kg feed) in broilers may improve feed conversion efficiency. The dietary supplementation with vitamin E (200 mg/kg feed) may increase anti-NDV titres and may enhance economic returns in broilers.

20. A Study On Single Nucleotide Polymorphism Of Chicken Growth Hormone Gene In White Cornish ,Lyall Pur Silver Black ,Aseel and Desi Chicken of Pakistan

by Mr.Imran Zahoor | Dr.Muhamad Akram | Dr.Abdul Waheed Sahota | Prof.

Material type: book Book; Format: print Publisher: 2008Dissertation note: The present study was conducted at Molecular Cytogenetics and Genomic Lab, Department of Livestock Production, University of Veterinary and Animal Sciences, Lahore and School of Biological Sciences, Punjab University, Lahore. For this Purpose twelve chickens, three each of four different breeds (White Cornish, Lyall pur Silver Black, Aseel, Desi,) were selected. LSB birds were collected from Agriculture University, Faisalabad. Where as birds of Desi and Aseel chickens were taken from Mianwali. White Comish birds were obtained from Big Bird Poultry breeders, Lahore. The pituitary gland of all the twelve birds of the above mentioned four breeds were taken out to extract the mRNA that was then converted into eDNA by using RT-PCR. Then that cDNA was amplified through PCR reaction. After amplification, the PCR products were loaded on agarose gel. Then these PCR products were cloned into vector in three steps. Firstly purified Gg GH mRNA was ligated into linearized pET22b. Then it was transformed into E. coli DH5CL with pTZ57R/GgGHG. Positive clones containing recombinant plasmid (pTZ57R/GgGHG) were screened by "Blue-White screening". Cells from a single colony for each of the W1 -W4 were resuspended separately in 50µl of sterile distilled water. This mixture was then used as template for PCR and the Gg GHG coding sequence cloned in plasmid DNA was then amplified and product was run on gel to study the result. These cloned products were used for the sequencing of growth hormone gene. Further results were obtained by using the consensus sequences of growth hormone of four breeds of chicken in ClustalW2 and Bioedit software and it was found that three SNPs were detected in Aseel, and one in each of Desi and LSB while comparing with White Comish. Out of three, first, second and third SNP were detected in Aseel at location of 261, 435 and 551 position of nucleotide in the exon portion of growth hormone gene, and C is replaced with G at location 261 and C is replaced with T at position 435 whereas at position 551, T is replaced by A. At these locations codon changes from CTC to CTG and TTC to TTC and TTC to TAC respectively. Only one SNP was detected in Desi and LSB at location 513 where A is replaced with G in both the breeds and codon change from AAA to AAG. To determine the relationship among all these breed (White Cornish, Aseel, Desi and LSB) a phylogenetic analysis was done. The phylogenetic tree was constructed using the presence and absence of restriction site and/or genotypic frequencies in the cGH motif of growth hormone gene. The phylogenetic consensus tree was constructed using the boostrapped data and neighbour-joining method. The Nei's genetic distance (Da) values of Aseel was 0. 00970, while comparing the genetic distances of White Comish with Aseel, it is found that there was a difference of 0 . 00320 and LSB has similar genetic distances and having no genetic difference among themselves. As LSB was evolved by crossing four different breeds Desi and White Leg Horn for female line and White Cornish and New Hampshire for male line so LSB is placed in-between Desi and White Comish as it has the 25% blood of Desi and 25% blood of White Cornish. Where as Aseel is different that's why it is placed far distant from three other breeds but as Aseel and Desi and LSB also are breeds of Asian origin and they were originated from red jungle fowl that's why Aseel, Desi and LSB (a cross of Desi with other three breeds; mentioned above) are placed more close to each other than White Cornish that is the breed of English class. In the present study, the Amino Acid compositions of the growth hormone of four different breeds of chicken were also studied and it was found that there although there were three mutations in Aseel but out of these three, two showed silent mutation and only one mutation was active. This active mutation cause change in the amino acid composition of the chicken growth hormone of these four breeds of poultry and in this study Phenylalanine is changed into Tyrosine at the location of 184t11 amino acid out of 191 amino acids (full length chicken growth hormone). But one mutation that was found in each of Desi and LSB in their comparison with White Comish were silent as the new sequences does not cause any change in amino acid sequence of growth hormone gene of Desi and LSB. CONCLUSION: In the present study, three SNPs were detected in the Exon region of the mRNA and one amino acid Phenylalanine is changed to Tyrosine, this amino acid change is in the conserved domain so it can be used as a marker for the further breeding program. RECOMMENDATIONS Present study laid the foundation of molecular techniques in the poultry but still 1. There is need of comprehensive study in which atleast 25 bird should be used in each strain. 2. Along with DNA study, there is need to study the phenotypic characters by rearing these strain upto three generations. Availability: Items available for loan: UVAS Library [Call number: 1003,T] (1).

21. Relative Biological Availability Of Feed Grade Dicalcium Phosphate & Monocalcium Phosphate And Their Effects on Productive Performance of Broilers

by Muhammad Asim Shahzad | Dr.Farine Malik Khattak | Dr.Abdul Waheed Sahota | Prof.Dr.Talat.

Material type: book Book; Format: print ; Literary form: not fiction Publisher: 2008Dissertation note: The live weights of different groups (A, B, C, D and E) gave non significant (p<O.05) results but numerically group D and E gave higher values, like wise, dressed weight were higher in group D and E. The dressing % of different groups (A, B, C, D and E) were also non significant (P>O.05). The liver weights of different groups (A, B, C, D and E) at 35 days of age were non significant (P<O.05). However within these groups, birds fed on control diet & DCP imported (group A & D) showed higher liver weights. Similarly there was n0 significant difference (p>O.05) in the heart and gizzard weights of different experimental groups. The result obtained in the course of this study highlighted an invaluable lesson. Regardless of the potential availability of the phosphorus in a feed phosphate, dietary factors and bird condition may result in a dramatically lower effective utilization of the phosphorus. It became evident that the availability of phosphorus was not an inherent property, characteristic of the material being assayed alone, but an experimentally determined value which reflects the absorption and utilization of the phosphorus ingested under the condition of the test.

Material type: book Book; Format: print Publisher: 2010Dissertation note: The study was designed to investigate the relative bioavailability of minerals in different vegetable protein sources commonly used in broiler ration. The study was conducted in the Poultry Experimental Shed, University of Veterinary and Animal Sciences, Lahore. For this purpose 200 day old broiler chicks were purchased and were randomly distributed into five equal treatment groups A, B, C, D & E containing soyabean based control diet, rapeseed meal, sunflower meal, canola meal and guar meal 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 day with in same treatment and replicate groups and 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 terminated 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 (Ca, P, K, Mg, and Na) and microminerals (Mn, Cu, and Fe) analysis. Data when statistically analyzed showed that there was a significant differences (P<0.05) between body weights, Birds fed canola and guar meal showed the highest (P<0.05) body weight compared to control birds. Feed consumption & FCR values showed a non significant difference (P<O.05). Organ weight revealed non significant difference in liver & heart weights (P<O.05), however significantly (P<O.05) highest weights were observed for birds fed diet containing guar meal. Amount of available Ca in plasma was significantly higher (P<O.05) when guar meal was fed as compared to P arid Mg which showed non significant (P<O.05) differences between treatments and the amount of available minerals Ca, P, Mg, K, and Fe in bone ash were also non significant (P<O.05) among birds fed control, rapeseed, sunflower, canola, and guar meal. The amount of available macrominerals (Ca, P, and Mg) in feed showed a significant difference (P<O.05) when birds were fed sunflower meal, control and guar meal. However, Na, and K levels of feed were non significant (P<O.05). The amount of available macrominerals (Ca, K and Na) in excreta significantly showed (P<O.05) difference when sunflower and guar meal were fed while P and Mg showed non significant (P>O.05) difference among all treatment groups, whereas microminerals like Cu, Mn and Fe showed a significant difference (P<O.05) when birds were fed a soya based control diet. The overall bioavailability of macro minerals (Ca, P, Mg, K and Na) and microminerals (Cu and Fe) showed significant (P<O.05) among treatments groups. However Mn showed non significant (P<O.05) difference with highest bioavailability of guar meal. The results showed that among protein source supplements, soybean, sunflower, canola and guar meal showed higher digestibility and minerals content as compared to rapeseed meal.

by Muhammad Karim Khan | Dr.Abdul Waheed Sahota | Prof.Dr.Khalid | Prof.Dr.Muhammad Akram.

Material type: book Book; Format: print ; Literary form: not fiction Publisher: 2010Dissertation note: The present study was designed to explore the photoperiodic effect of intermittent lighting on various economic traits as well as egg quality traits initiating from post peak egg production in quails. This study was conducted at Avian Research and Training (ART) Centre, Ferozpur Road Lahore with both local and imported quails maintained under different continuous and intermittent lighting regimes. The experimental quails were subjected to 05 different lighting regimes viz., A (16L: 8D), B (8L: 6D: 2L: 8D), C (8L: 7D: IL: 8D), D (8L :7.5D: 0.5L: 8D) and E (8L: 16D) from 23 -34 weeks of age. The group E (8L: 16D) served as a negative control and group A (16L: 8D) was a positive control, while, the three intermittent lighting regimes used as experimental treatments were named as B, C and D. From 15th to 221I1 week the quails were maintained on a long day lighting schedule of (16L: 8D) in order to create uniformity among birds. The effect of these above mentioned lighting schedules on early productive performance of this flock of quails was examined in another study. In this trial the same act of treatments was used to investigate its lighting effect on post peak production (from 23 to 34 weeks). The experiment was conducted on 240 adult quails (23 weeks old) under factorial arrangements of 5 lighting regimes x 4 purebred strains x 3 replicates having 4 quails (1 male: 3 female) each. The experimental quails were maintained in a 5 tier quail battery (each tier had 6 decks). The study was conducted under the same manage mental conditions. The weekly data on body weight, egg production, FCR (for egg production and egg weight), egg quality traits (egg weight, shell weight, shell thickness, haugh unit and yolk index were recorded. The data thus collected were statistically analysed using analysis of variance technique and comparison of means was made using DMR test. The results of the present study show that mean body weight under light regimes A, B, C, D and E was recorded as 268.81 (+5.09), 280.70 (+12.3), 267.96 (+2.99), 274.10 (+12.3) and 271.20 (+10.3)gm, respectively. A significant (p<0.Ol) effect of light treatments on body weight was observed. The highest body weight (280.70+12.3gm) was recorded under treatment B (8L: 6D: 2L: 8D)which was found to be significantly better than recorded under other treatments, however, A and C and D and E differed non- significantly from each other. Breed differences in body weight were observed to be significant (p<0.Ol). Significantly (p<O.O5) higher body weight was observed in strain M. Body weight between M and K and S and Z strains varied non-significantly. Light and breed interaction was found to be significant (p<O.Ol). The results on feed intake followed almost a similar pattern indicating significant (p<O.Ol) effect of light treatments, breeds and light into breed interaction. However, feed intake under light treatment A (16L: 8D) was more, which varied non-significantly with light treatment D (8L: 7'/2D: '/2L: 8D). The highest feed consumption (p<O.O5) in strain M, which also ranked best in body weight. A non-significant difference in feed intake of M and Z and S and K strains was observed. The mean egg production of quails under lighting regimes A (16L: 8D), B (8L: 6D: 2L: 8D), C (8L: 7D: 1L: 8D), D (8L: 7V2D: V2L: 8D) and E (8L: 16D) during the experimental period was recorded as 79.49, 74.65, 75.99, 76.33, 75.64 percent, respectively. The effect of lighting treatment was found to be significant (p<O.O5) on mean egg production. The birds in positive control group produced significantly (p<O.O5) more eggs when compared with birds on experimental treatments. The results indicated that light treatments of quails during growing period significantly (p<O.Ol) influenced the feed conversion ratio (feed/dozen egg) of quails during post peak production with significant (p<O.Ol) breed and light into breed interaction. FCR of quails of negative control group E (8L: 16D) was significantly (p<O.O5) better than all other light treatments. The strain Z exhibited better (p<O.O5) FCR than the strains M and S, however a non-significant difference between Z and K strains was recorded. A similar trend for FCR (feed/kg eggs) was observed except that Z strain exhibited better FCR than other three strains. The results showed non-significant close bred strain as well as light into breed effect. Breeds differed significantly (p<O.O5) in egg weight and K strain had greater egg weight than the other strains. The results in respect of yolk index and yolk height showed a similar trend. The yolk index in K strain was found to be better (p<O.Ol) than other strains except M strain. The yolk height was observed to be significantly better (p<O.O5) in strain M when compared with S and K strains, however, a non-significant effect between close bred strain M and K was observed. The results showed that quails subjected to different lighting regimes during the experimental period significantly (p<O.Ol) influenced egg shell thickness. The birds on experimental regime B (8L: 6D: 2L: 8D) produced significantly (p<O.O5) thicker shells than other competitive treatments. Breed and light into breed effect was also found to be significant (p<O.O5). Strain Z had the greatest shell thickness than all other strains. The results of the study in respect of other egg quality traits such as Haugh unit, egg shell weight, yolk diameter and albumen height showed non-significant effect ofdifferent lighting regimes applied during experimental period. The effect of breed and light into breed interaction was found to be non-significant. Availability: Items available for loan: UVAS Library [Call number: 1109,T] (1).

by Dr. Bashir Ahmad Khawaja | Dr. Mohammad Saleem Chaudhary | Dr. Asaf | Dr. Mohammad Aslam Bhatti.

Material type: book Book; Format: print Publisher: 1990Dissertation note: The purpose of the experiment was to study the effect of various floor spaces on growth rate, egg production and hatchability of quail (coturnix coturnix Japonica) in cac7es. One hundred and eighty, one day old quail chicks were purchased from a local commercial hatchery and were divided into four equal groups of 45 chicks i.e. A, B, C, and D. These groups were further sub divided into 3-replicates of 15 chicks each providing floor spaces of 144, 165, 186 and 206 sqcm/bird respectively. The chicks were fed ad-libitum on a commercial ration. The other managemental and environmental conditions iiere similar for all the groups. Experimental chicks were weighed individually at one day old and on weekly basis upto the age of 8-weeks. The average wt. gain observed/quail upto 8-weeks of age for groups 4, B, C and D was 120, 135, 144 and 150 gins respectively. Average feed consumption/quail was found to be 433, 478, 496 and 515 gms respectively. The feed conversion ratio (F. C.R.) was 3.60, 3.54, 344 and 3.43 in groups 4, B, C and D respectively. The total number of eggs produced by the birds of respective groups were 9, 10, 10.5 and 12 eggs/hen in 14 days of laying period. Total number of chicks hatched on 17th day of .incubation in groups A, B, C and D wet-e 120, 130, 138 and 144 respectively. The mortality percentage was 8.88, 4.44, 2..22 and 0.00 in groups A, B, C and D respectively. The average dressing percentage for birds in groups A, B, C and P was 67.45, 67.47, 67.97 and 69.42 respectively. Average heart wt. was apparently more in the birds of group C than those of 4, 8, and P. Similarly group P birds exhibited apparently maximum wt. of liver than the other three groups. The average wt. of gizzard was maximum in group P than rest of the groups. Statistical analysis of the data revealed highly significant effect of floor space on wt. gain, feed consumption, F.C.R., egg production and hatchability. However floor space effect on dressing percentage and giblet weight (liver, heart and gizzard) was statistically non significant. The monetary return per 100 gm of live body wt. was Rs. 1.43, 1.84, 2.07 and 2.18 in the birds of groups A, B, C and I) respectively. Finally it was found that quails can be reared in cages at a density of 206 sq.cm/bird efficiently and economically without any detrimental effect on growth rate, F.C.R., feed consumption, egg production and hatchability in quails.

25. Effect Of Different Light Colours And Patterns On The Performance Of Broilers

by Athar Mahmud | Dr. Ehtisham Pervez | Dr. Javed | Dr. M. Aslam Bhatti.

Material type: book Book; Format: print ; Literary form: not fiction Publisher: 1990Dissertation note: Although poultry industry is dynamic for having tremendous potential to produce quality protein from meat and eggs which has a significant impact on the economy of our country. Yet it is not a stable business because a slight variation in environment upsets its profit margins. Different lighting schedules play a prominent role for rearing the broiler birds. In recent years efforts have been made to develop more efficient lighting schedules so as to save the electricity expenditure and to produce cheaper broiler meat. An experiment therefore, was designed to work out an ideal lighting pattern. In this experiment two hundred and twenty day old chicks were reared together for the first fifteen days, then one hundred and eighty chicks were randomly selected and subjected to different lighting patterns and clours of red, green and normal lights. They were divided in to groups i.e. A,a B,b and C,c exposed to continuous and intermittent pattern of red, green and normal light. The maximum weight gain was obtained by group subjected to green continuous lght and the lowest by group exposed to normal intermittent light. Likewise the maximum amount of feed was consumed by the group provided normal continuous light and minimum by the group exposed to red intermittent light. So far as the FCR is concerned, it was comparatively better in green continuous light group and poorest in normal intermittent light group. Another purpose of this experiment was to observe whether coloured and intermittent pattern of lights have better effects than that of the normal ones. The chicks subjected to green continuous light gave better body weight and FCR as compared to all other treatments. The results of the experiment suggest that we can save both electricity and feed by rearing broilers under continuous green lighting pattern.

26. Evaluation Of Post Peak Production Of Commercial Layers And Fed On Extruded Hatchery Waste Meal

by Rafiullah | Dr. Athar Mahmud | Prof. Dr. Muhammad Akram.

Material type: book Book; Format: print Publisher: 2010Dissertation note: Poultry feed ingredients are very expensive and raises poultry input cost with an inverse impact at final outcome. To decrease the feed cost and to increase farming output, utilization of non conventional feed resources such as hatchery waste meal (HWM) may be used in layer feed and seems a good economic properties. For this purpose the present study was designed to exploit post peak production of commercial layers supplemented with dietary extruded hatchery waste meal and this trail was carried out at poultry experimental farm University of Veterinary and Animal Sciences Lahore. Two experiments were conducted at the poultry experimental farm. In the first experiment raw hatchery was collected from a local hatchery and was dried at oven in 60°C till constant weight was achieved. The dried sample was then cooked by extrusion processes. In the second experiment the dietary inclusion of extruded hatchery waste meal (EHWM) was determined on performance of layer birds. For this purpose two hundred and fifty (250) White Leg horn layers in start of 2nd stage of production (35 weeks old) was procured and divided in to five groups (A, B, C, D and E) in such a way that there were fifty birds in each group. Each group was then further sub divided in to five replicates of ten birds. Group A served as a control. The experimental layers were being kept in cages with the standard norms of husbandry. The duration of experiment was 8 weeks. Four different supplementary levels of extruded hatchery waste meal of groups B, C, D, and E respectively, i.e. 2%, 4%, 6%, 8% were incorporated in layers diet. The parameters studied daily egg production and egg weight, while shell weight, shell thickness, albumen weight, albumen height, yolk weight, yolk diameter, yolk color, and Haugh units were studied on fortnight basis. At the end of the experiment the feasibility of each ration was also calculated. The data thus collected were statistically analyses using analysis of variance technique and comparison of means was made using DMR test. In the present study the high mean egg production was recorded in treatment 4 (53.2±1.15) in which 6% extruded EHWM was used while the lowest mean egg production was recorded in treatment 2 (49.9±1.82) in which 2% of extruded HWM was used. The result of the present study show non-significant (p>0.05) effect of extruded hatchery waste meal on egg production. Highest value of average egg weight (60.4±0.48) was observed in control group while lowest value (59.2±0.53) was observed by using 8% EHWM. Statistical analysis showed non-significant (P>0.05) effect among treatments. Highest value of mean egg shell weight (7.3±0.17) was observed by using 4% extruded HWM. Lowest value of mean egg shell weight (7.2±0.06) was observed by using 8% HWM. The high value recorded for shell thickness was that of treatment 4 (0.33±0.008) by using 6% dietary EHWM, while lowest value was recorded in treatment 5 (0.31±0.002) using 8% dietary EHWM. The result of mean shell weight and shell thickness also showed non-significant differences (p>0.05) among different treatments. The results of albumen weight, albumen height and Haugh units showed non-significant (p>0.05) effect of feeding different dietary levels of EHWM to commercial layers. However the highest values recorded for albumen weight and albumen height were (37.5±0.61) and (8.53 0.134) respectively in control group which was without of dietary EHWM. The highest value observed for Haugh units was (91.8±0.57) that of treatment 3 by using 4% EHWM. However albumen weight, albumen height and Haugh unit showed statistically non significant (P>0.05) effect of EHWM fed on experimental commercial layers. The values for yolk weight, yolk diameter and yolk color were observed in order of merit for treatment, 2 (2% EHWM) (16.0±0.17), treatment 3 (4% EHWM) (38.8±0.11), and treatment 5 (8% EHWM) (5.5±0.15) respectively. Statistically the yolk weight, yolk diameter and yolk color showed non-significant (P>0.05) effect of EHWM on layers performance. The economic feasibility of each ration was calculated at the end of the experiment. The feed cost per kg and the cost of 1 kg eggs were decreased gradually as dietary supplementary level of HW was increased from 2 to 8% in the diet of commercial layers. The most economical ration was that of treatment 5 in which 8%EHWM was used. Availability: Items available for loan: UVAS Library [Call number: 1202,T] (1).

by Muhmmad Iqbal | Dr. Abdul Waheed Sahota | Prof. Dr. Muhammad Akram.

Material type: book Book; Format: print Publisher: 2011Dissertation note: In Pakistan rural poultry has been playing an important role in the production of eggs and poultry meat. During the year, 2010, the contribution of rural poultry in overall production of eggs and poultry meat in the country has been about 32.15 and 15.38 percent, respectively. However, conservation and genetic improvement of native poultry breeds has been the major problem hindering the development of rural poultry. Aseel is a native rural poultry breed which possesses very good meat production character, however very little research work has been conducted to study its growth and carcass traits. Keeping this in view, the present study was planned to evaluate comparative growth and carcass traits of different varieties of native Aseel. For this purpose 96, day-old Aseel chicks, 24 each of 4 different varieties viz Peshawari, Mianwali, Mushki and Lakha were maintained under standard managemental conditions for a period of 15 weeks according to Completely Randomized Design. The data on weekly body weight gain and feed intake were collected and feed conversion efficiency was worked out. At 12 and 15 weeks of age, carcass characteristics such as dressing percentage, shank length and width, breast length and width, intestinal length and weight and giblet weight were studied The average feed intake (g) of four varieties of Aseel varied significantly (p>0.05) from 1 to 15 weeks of age. The average body weight (g) of four varieties of Aseel was significantly differed at 4th, 5th, 6th, 7th, 10th, 13th, 14th and 15 weeks of age. However, non-significant effect was observed at day-old chick and also at 1st, 2nd, 3rd, 8th, 9th, 11th and 12th weeks of age. The average of weekly body weight gain (g) of four varieties of Aseel significantly differed at 4th, 5th, 8th, 9th and 10th weeks of age. However, non-significant effect was observed at 1st, 2nd, 3rd, 6th, 7th, 11th, 12th, 13th, 14th and 15th weeks of age. The average of FCR of four varieties of Aseel was varied significantly (p<0.05) at 1st, 4th, 5th, 8th, 9th and 11th weeks of age, however, non-significant effect was observed in 2nd, 3rd, 6th, 7th, 10th, 12th, 13th, 14th and 15th weeks of age. The average mean of times weekly body weight gain of four varieties of Aseel significantly varied (p<0.05) at 3rd, 4th, 8th, 9th and 10th weeks of age. Non-significant effects was however observed at 1st, 2nd, 5th, 6th, 7th, 11th, 12th, 13th, 14th and 15th weeks of age. The weekly average mean intake of protein, calories, calcium, phosphorus and fiber in four varieties of Aseel significantly differed (p<0.05) throughout the experimental period from 1-15 weeks of age. The results of this study in respect of carcass characteristics indicate that Aseel males had higher live body weight, weight with viscera, dressed weight, shank length, shank width, than Aseel females at 12 and 15 weeks of age. However non-significant differences were observed among the four varieties of Aseel at both 12 and 15 weeks of age in these parameters. The results indicated that males had higher, gizzard weight (with contents), gizzard weight (without contents), breast width, and breast length, than Aseel females at 12 weeks of age. However, non-significant differences were observed between sexes at 15 weeks of age and also among the four varieties of Aseel at both 12 and 15 weeks of age in the above mentioned parameters. Aseel males also exhibited higher intestinal and proventriculus weights than those of Aseel females at 12 weeks of age, however, non-significant differences were observed between sexes at 15 weeks of age in both these parameters. Significant difference in proventriculus and blood weight was observed among the four varieties of Aseel at 12 weeks of age, whereas, non-significant difference was recorded in proventriculus and blood weight at 15 weeks of age. The results indicated non-significant differences between the sexes at both 12 and 15 weeks of age. Aseel males had higher intestinal length and lungs weight, than that of Aseel females at 15 weeks of age, however, non-significant difference in these parameters was observed between the sexes at 12 weeks of age and also among the four varieties of Aseel at both 12 and 15 weeks of age. Non-significant differences were noted in liver, heart, abdominal fat and spleen weight among the four varieties of Aseel at 12 and 15 weeks of age. Similarly, non-significant difference was observed between the sexes in respect of liver weight and also non-significant difference was recorded in intestinal weight between the four varieties at 12 weeks of age. Whereas, significant differences were observed in these parameters among four varieties of Aseel at 15 weeks of age. Significant difference was observed in abdominal fat percentage among the four varieties of Aseel at 12 weeks of age, however, non-significant differences was found among the four varieties at 15 weeks of age. The sexes differed non-significantly in abdominal fat percentage and also non-significant difference was observed in testes and ovary weight among the four varieties of Aseel at 12 and 15 weeks of age.

28. Productive Performance Of Four Close-Bred Flocks Of Japanese Quails With Different Body Weights And Its Effect on Subsequent Progeny Growth

by Ahmed Sultan | Dr. Abdul Waheed Sahota | Dr. Khalid Javed | Dr. Muhammad Akram.

Material type: book Book; Format: print ; Literary form: not fiction Publisher: 2012Dissertation note: In Pakistan, the low live and dressed market weights in Japanese quails has been one of the significant problems badly influencing future development in quail production. No serious attempts have yet been made in the country to improve body weight and meat yield in local quails. The present study of one year duration was therefore, planned at Avian Research and Training (ART) Centre, Department of Poultry Production, Faculty of Animal Production and Technology, University of Veterinary and Animal Sciences, Lahore. The main objectives of the study were to evaluate productive performance, egg quality, hatching performance, slaughter characteristics and blood biochemical profile in four close-bred flocks of Japanese quails with different body weights and examine its effect on the subsequent progeny growth. For this purpose, a total of 432 (108 males and 324 females) adult quails were randomly picked up from 4 close-bred flocks maintained at ART Centre and then were divided into 108 experimental units/ replicates (comprising 1 male and 3 females each). These experimental units were randomly assigned to 12 treatment groups, having 4 close-bred flocks (imported, local 1, local 2, and local 3) x 3 female body size (heavy, medium and small) with randomized complete block design (RCBD) in factorial arrangements having 9 replicates in each treatment. The experimental quails were maintained under standard management conditions in individual compartments in multi-deck cages equipped with separate nipple drinkers and were fed ad-libitum with a quail breeder ration prepared according to NRC standards. The weekly data on productive performance (body weight, egg production and feed intake) were recorded. Feed conversion ratio (g feed/egg and g feed/g egg mass) was worked out. Egg quality characteristics (egg weight, shell weight, shell thickness, haugh unit, yolk index, and blood and meat spots) and hatching traits (dead germ percent, dead in shell percent, infertile egg percent, hatchability percent and mal-positions) were recorded. At the termination of the experiment, two breeder quails from each experimental unit (one male and one female each) were randomly picked up and were slaughtered to record the slaughtering traits (live and dressed weight, dressing percentage, weight of giblets and other visceral organs). Proximate composition (crude protein, ether extract, dry matter and ash contents) of thigh and breast meat was determined. Blood samples from each group were analyzed for blood serum glucose, total protein, albumin, cholesterol and urea. Blood macro mineral profile for plasma calcium (Ca), phosphorus (P), sodium (Na), potassium (K) and magnesium (Mg) was determined. The eggs from each replicate were collected and separately incubated on fortnightly basis to study 3 weeks progeny growth performance (average weight of day-old quail chicks, weekly body weight, weight gain, feed intake, feed conversion ratio (feed/g gain) and mortality rate). At the end of 3rd week, 2 quails (one male and one female each) from each experimental unit were picked up randomly and were slaughtered to record slaughtering traits (slaughter and dressed weight, dressing percentage, weight of giblets and visceral organs). Economics of quail production up to 3 weeks was worked out. The data thus collected were analyzed using analysis of variance (ANOVA) technique with randomized complete block design (RCBD) under factorial arrangement for further interpretation using general linear model (GLM) procedures (SAS, 9.1 version). The comparison of means was made using Duncan's Multiple Range (DMR) test. 6.1. Parent breeder flock In the present study of 31 weeks duration, imported flock of Japanese quails gained significantly higher body weight than local flocks. With respect to body size categories, there was a significant (p<0.05) difference in their mean body weight. The interaction between flocks and body size was also observed to be significant (p<0.05). The heavy weight quails had maximum body weight followed by that of medium and small size quails. The difference in mean egg production percentage, egg number and feed conversion ratio (g feed/egg) were not significant, whereas, egg weight was significantly (p<0.05) higher in 4 close-bred flocks of Japanese quails. Mean feed conversion ratio (g feed/g egg mass) in imported and local-3 flocks of Japanese quails was significantly (p<0.05) different from other local flocks. The body weight categories had significant (p<0.05) effect on egg production percentage, egg number, feed conversion ratio (g feed/egg) and egg weight, however, their effect was not significant on egg mass. The interaction between flocks and body size showed a similar trend. The mortality remained nil in the experimental breeder quails during this study. The significant (p<0.05) differences were noted in egg weight, shell weight, shell thickness, yolk index, dead germ, infertile egg and hatchability percent, whereas, haugh unit value was not significantly different in all the close-bred flocks of Japanese quails. The dead in shell percent in different close-bred flocks was significantly (p<0.05) different in all the parental groups except in H male x H female, M male x H female, S male x M female and S male x S female. With respect to body size categories, differences for egg weight, shell weight, shell thickness, yolk index, haugh unit value, dead germ, infertile egg and hatchability percent were significant (p<0.05). The interaction between flocks and body size was significant in respect of all the above egg quality and hatching traits. Blood and meat spots were found nil and no mal-positions were noted. The minimum dead germ percent was recorded in local-2 and local-3 flocks in S male x H female, however, the highest hatchability percent was recorded in M male x S female parent of local-3 flock. The significant (p<0.05) effect of parental body weight on dead in shell percent was recorded in H male x M female (in imported, local-1 and local-2 flocks), H male x S female (in imported and local-1 flocks), M male x M female (imported and local-1 flocks), M male x S female (imported and local-1 flocks), S male x H female (imported and local-1 flocks). The dressed weight (g) in imported and local flocks of Japanese quails was significantly (p<0.05) different in female quails, whereas, dressing percentage in imported and local flocks of male Japanese quails was not significantly different. With respect to body size categories, there was a significant (p<0.05) difference for dressed weight and dressing percentage in both the sexes. The imported flock of male Japanese quails was significantly (p<0.05) different from all the other local flocks in relative weight of gizzard (with and without contents) .Imported and all the local flocks of Japanese quails were not significantly different in their relative weight of liver in both the sexes. The relative weight of heart and mean weight of intestine in local-3 flock of male Japanese quails were significantly (p<0.05) different, whereas, female birds were not significantly different in this respect from all the local and imported flocks. With respect to body size categories, relative weight of heart, liver, gizzard and intestines in both the sexes were not significantly different. The interaction between flocks and body size was not significant for liver weight, whereas, it was significant (p<0.05) for heart, gizzard and intestinal weight only in male quails. The intestinal length and testes weight in male and mature ovarian follicle number and reproductive tract weight in female quails were not significantly different in imported and local flocks. With respect to body size categories, differences in mean length of intestine and mean weight of testes were not significant in male quails. The similar non-significant difference in reproductive tract weight and number of mature ovarian follicles was recorded in female quails.

CONCLUSION Based on the findings of this study, the following conclusions have been formulated. i. Parent breeder flock a. Effect of close-bred flocks i. Imported flock of quails had significantly (p<0.05) better egg production percentage, egg weight, yolk index, feed conversion ratio-FCR (g feed/g egg mass), shell weight and dressing yield. Feed conversion ratio (g feed/egg) and egg mass were significantly (p<0.05) better in local-1 and local-3 flocks, respectively. Egg shell thickness and haugh unit were better in local-2 flock. ii. Final live body weight was higher in female than male quails and it was also better in local-1 male quails than in other close-bred flocks. iii. Reproductive tract weight and length and mature ovarian follicle numbers were higher in imported flock. Significant variation was recorded in relative weight of giblets, testes and intestines and intestinal length among different close-bred flocks. iv. The imported male flock had significantly (p<0.05) higher crude protein, dry matter and ash contents in breast and thigh meat. v. The mean serum glucose and cholesterol concentrations in local-1 male flock and mean serum albumin and urea levels in local-3 male flock were higher; however, total serum protein was also higher in male imported flock than in other local flocks. vi. Plasma phosphorus and potassium concentrations were not significantly different in male parents, whereas, plasma magnesium concentration was not significantly different in female parents. Plasma calcium was significantly (p<0.05) different in both the sexes. b. Effect of body size i. Egg production percentage, feed conversion ratio (FCR), fertility and hatchability percent, reproductive tract weight and length, mature ovarian follicle number and gizzard weight were better in small parents in comparison to medium and heavy parents, whereas, better egg weight and egg quality traits were recorded in heavy quail parents. Dressed weight and dressing percentage were higher in heavy female parents than in medium and small quails. ii. Crude protein and ether extract contents in breast and thigh meat were higher in heavy female parents, whereas, ash content was higher in thigh meat of heavy female parents. iii. The higher concentrations of serum glucose, total protein, albumin and cholesterol in heavy male quails were detected, whereas, serum urea was higher in medium female parents. iv. Plasma macro minerals profile for all the parameters studied was not significantly different in male parents, whereas, plasma calcium (Ca) was not significantly different in both the sexes. 6.3.2. Progeny flock a. Effect of close-bred flocks i. The day-old and subsequent weekly body weights/weight gain and feed intake were higher in imported than in local flocks. The lower feed intake and better feed conversion ratio-FCR (feed/g gain) and higher mortality rate were recorded in local-3 as compared to other flocks. ii. Dressed weight and dressing percentage were higher in male progeny of imported flock. The liver, heart and gizzard weights were higher in local-2 and local 3 male flocks, whereas, higher weight of intestine was recorded in local-1 male flock. Significant variation in carcass traits between different close-bred flocks was observed. iii. The highest final return per bird of Rs. 5.64 was observed in local-1 flock followed by imported, local-3 and local-2 flocks (Rs. 5.41, 5.15 and 5.14, respectively). b. Effect of parent body size i. The progeny secured from heavy male parent had higher hatch weight, body weight, weight gain, feed intake, dressed weight and dressing percentage than those hatched from medium and small male parents, showing more pronounced effect of male parent on progeny growth and on almost all the other parameters. ii. The liver and gizzard weight and intestinal length were higher in quail progenies secured from small parents than from heavy and medium parents. iii. The highest final return per quail (Rs. 5.92) was recorded in medium weight parent followed by heavy and small parents (Rs. 5.25 and 4.90, respectively). ? SUGGESTIONS AND RECOMMENDATIONS Research The findings of the present study may be helpful in setting up production standards in local quails to be further used as base line data by the research workers and quail breeders for formulating viable future strategy of quail breeding at national level. Extension For the future national quail breeding programs, use of heavy male parents for crossing with medium or small female parents may be considered for better progeny meat yield and higher egg production in the female quail parents. Considerable variations in body weight and other carcass characters in our local quail flocks recorded during the course of this study indicate possibility of further improving their genetic potential. Further research work is needed for improving genetic potential of our local quail stocks. Availability: Items available for loan: UVAS Library [Call number: 1524,T] (1).

Material type: book Book; Format: print ; Literary form: drama Publisher: 2013Dissertation note: The aim of study was to find out the method for disposal of waste material, dead birds and poultry litter and their proper utilization in the poultry industry. Secondly to evaluate the efficacy of composted poultry litter/dead birds in broiler quail ration. The experiment was conducted at Poultry Research and Training Centre and Avian Research and Training Center, UVAS, Lahore in two different phases. The first phase was of 8 weeks duration in which composting of dead birds was doneusing advance windrow pile technique and proximate analysis of the composted material wascarried out. During the second phase, a quail ration was formulated according to dietary recommendations of NRC (1994) with inclusion of 0, 2, 4 and 6% compost and fed to quails,For this purpose, a total of 1200 day old Japanese broiler quails were randomly divided into 4 different experimental groups (A, B, C, and D). Group A was control and group B, C, and D contained 2, 4, and 6% composted ration respectively. The birds in each group were replicated six timescomprising 50 birds in each replicate. After 4 weeks of age three birds per replicate were slaughtered and their slaughtering parameters were recorded. The data thus obtained were analyzed through ANOVA in completely randomized design (Steelet al.1997) and means were compared by Duncan's Multiple Range (DMR) test (Duncan, 1955) using SAS (Statistical Analysis System) version 9.1. In production performance feed intake, body weight, body weight gain and FCR showed positive response when fed different levels of composted diet while mortality % remained unaffected throughout the experimental period. In slaughtering parameters live body weight (g), carcass weight %, dressing Weight %, Giblet weight %, Gizzard weight % and Heart weight % showed positively when fed different levels of composted diet while liver weight % remained unaffected throughout the experimental period.

32. Effect Of Dietary Supplementation Of Different Lutein Sources On Production Performance, Egg Quality And Its Bio-Availability in Eggs of Commercial Layers Categorized in THree Body Weights

by Ahmad Ali Sajjad | Dr. Athar Mahmud | Prof. Dr. Muhammad Akram.

Material type: book Book; Format: print ; Literary form: not fiction Publisher: 2013Dissertation note: The term Designer egg has gained popularity all over the world. Egg which gives some health benefits with the provision of basic nutrients is called designer egg. Lutein a xanthophyll pigment is good for the prevention of age related macular degeneration (AMD).Egg is considered good vehicle for lutein transport as bio-availability of lutein is high through egg. The present study was aimed to produce lutein enriched eggs (designer eggs). Different sources of lutein were used and their effect on production performance and egg quality characteristics was measured. A total number of 432 Hy-line layers categorized into 3 body sizes (Heavy, Medium, Light) were offered 4 different supplementations of lutein (0, free, esterified, free + esterified) replicated 6 times having 6 layers each. Parameters regarding production performance, egg geometry and egg quality were observed.Data were analyzed according to Analysis of Variance (ANOVA) technique through Completely Randomized Design (CRD) using factorial arrangement. Means were compared through Duncan Multiple Range Test (Duncan, 1955) with the help of SAS 9.3. Results of the present study showed significantly higher Haugh unit score (87.17±0.39) in light birds during 3rd week whereas, within lutein sources significantly higher Haugh unit score was observed in layers fed with control diets (85.52±0.48). Significantly (p<0.05) higher yolk pH was observed in layers fed with esterified source of lutein whereas significantly higher (8.26±0.06) albumen pH was observed in birds fed with free source of lutein however, different body sizes could not show their effect on yolk and albumen pH. Significantly higher (62.97±0.22) albumen % was observed during 1st week of study in birds fed with esterified source of lutein whereas body weight categories did not affect the albumen% whereas, yolk % was affected by different body sizes and lutein sources during 1st week of study. Significantly higher mean value (27.48±0.27) of yolk % was recorded in birds fed with combination of free and esters of lutein whereas higher value of yolk % (27.20±0.23) was observed in medium birds. Shell percentage significantly (p<0.05) affected by different body sizes (10.96±0.13) and lutein sources (11.14±0.18) during 1st week of study whereas shell thickness was significantly (p<0.05) affected by lutein sources (0.35±0.004) during 1st week of study. Means of different sources of lutein had significant (p<0.05) effect on yolk color and the highest mean value (11.63±0.15) was observed in birds fed with free source of lutein. Yolk index was significantly (0.36±0.005) affected by different lutein sources however, body sizes did not affect yolk index. As far as egg geometry was concerned egg surface area and egg volume were found to be significantly highest for heavy birds whereas non-significant differences for egg volume and shape index were observed. However, different lutein sources had no effect on egg geometry parameters. Significantly highest egg weight (62.74±0.23) was observed in heavy layers followed by medium (61.56±0.17) and light (60.63±0.17). However, different body weights (narrow ranges) and lutein sources had non-significant effect on production (%), FCR per dozen, egg mass and FCR per kg egg mass.

33. Effect Of Different Levels Of Defatted Algae Supplement Of The Growth Performance, Blood And Tissue

by Ahsan Mustafa | Dr. Abdul Waheed Sahota | Prof. Dr. Muhammad Akram.

Material type: book Book; Format: print ; Literary form: not fiction Publisher: 2013Dissertation note: In Pakistan poultry sector is playing a vital role in bridging the gap between supply and requirement of animal protein food for its ever increasing human population. The contribution of poultry sector in agriculture and livestock is about 6.4 and 11.5 percent, respectively (Anonymous, 2012). Poultry meat contributes about 25.8 percent of the total meat produced in the country. This sector has been growing at an annual rate of 8 to 10 percent, producing 131.4 million eggs and 0.834 million metric tons of poultry meat (Anonymous, 2012). However, despite this tremendous growth rate, this sector is facing many challenges which may badly influence its future pace of development. The most important of these is escalating cost of poultry feed which is considered to be the major cost item involving more than 60 to 70 percent share of production cost (Khan et al., 2010). Many of the traditional protein sources used in poultry diet formulations such as soybean, fish, sunflower meal and groundnut meal are becoming extremely expensive. Rapid growth of human, livestock and poultry population has increased the demand for food and feed which has necessitated that alternative feed resource should be identified and evaluated. Therefore, the search for alternative protein sources has become urgent, and in this context, algae are worthy of consideration. The possibility of using fat-extracted algae (a by-product from bio-fuels production) as a source of protein and other nutrients in poultry feeds appears to be of great significance. The use of algae as a source of nutrients can benefit poultry and bio-fuel industry. Diatoms are a major group of unicellular algae, and are one of the most common types of phytoplankton. They differ from other algae in the presence of substantial amounts of silicon in their cell membranes. The diatom, Nanofrustulum is currently under investigation as a potential source of oil for bio-fuel production. However, effect of dietary inclusion of defatted algae supplements by replacing soybean meal and corn on the performance of broilers has not yet been thoroughly investigated. The present study was therefore under taken at Poultry Research Farm, Department of Animal Science, University of Cornell, USA, to investigate effect of defatted algae Nanofrustulum meal on the growth performance, blood biochemical composition and gross pathology of tissues in broilers. For this purpose, two levels of defatted algae Nanofrustulume 7.5 and 10 percent were used. Four different, iso-caloric and iso-nitrogenous experimental rations were prepared. The diet A was prepared without inclusion of algae (control), whereas in diets B and C the same algae at the rate of 7.5 percent were incorporated to replace soybean meal and soybean meal + corn, respectively. In diet D, algae at the rate of 10 percent replaced soybean meal and corn. Eighty, commercial (Ross), day-old, broiler chicks, 40 each of both sexes, were randomly divided into to 4 treatment groups (A, B, C and D) with two replicates each of 5 male and female birds per treatment. They were initially weighed and wing banded individually for identification and then maintained in thermostatically controlled battery cages. The birds were provided 22 hours light: 2 hours darkness schedule. All the experimental birds were fed a balanced broiler starter ration and water ad libitum until 21 days of age. All the experimental rations were supplemented with additional quantity of potentially limiting amino acids, lysine and methionine. The amount of corn oil in all the rations was adjusted to maintain metabolizable energy contents at 3000 and 3200 Kcal/Kg for the chick starter and grower rations, respectively. The amino acid contents of starter and grower diets were kept higher than NRC (1994) standards. On day 22nd, the birds were transferred to growing cages maintained at room temperature and similarly fed grower diets ad libitum until 42 days of age. The data on feed intake, body weight gain were collected. Feed conversion efficiency were calculated. On day 42nd of the experiment, the experimental birds were fasted for 3 hours and blood samples were collected from the wing vein from randomly selected, 2 birds each of both the sexes per replicate for determination of blood biochemical composition following standard laboratory procedures. Gross pathology of tissues obtained from slaughtered birds was also performed. The study was conducted according to Randomized Complete Block. Design (RCBD). The data thus recorded was subjected to statistical analysis using Analysis of Variance Technique (Steel et al., 1997). The means were compared using Duncan's Multiple Range (DMR) Test (Duncan, 1955). The results of this study showed significant (p?0.01) difference in average feed intake among treatments and between sexes of broilers. In male broilers, the significantly highest feed intake was observed in birds fed diet C followed by those fed diets D, A and B, whereas in female broilers the highest feed intake was recorded by the birds fed diet A and then followed by those fed diets B, C and D. The results further showed non-significant differences in feed intake of male broilers between treatment groups C & A and C & D, whereas significant difference was recorded between group B and C. Significantly lowest feed intake was recorded in female broilers fed diet D which was also significantly different from treatment groups A and B. The results also showed that with increase in inclusion levels of algae in female broilers depression in feed intake increased. The results in respect of average weight gain showed that male and female broilers fed the control diet attained the highest weight gain, followed by those fed diets C, D and B, respectively in male broilers and fed diets C, B and D in female broilers, respectively. The male broilers attained significantly (p<0.01) better weight gain than female broilers. The weight gain in broilers fed the control diet was not significantly (p?0.05) different from those fed diet C. The overall results of the study showed depression in weight gain of birds fed diets containing different levels of algae in comparison to those fed control diet. In the present study, the feed conversion ratio was significantly (p< 0.05) influenced by the diets, however it was not significantly different between sexes. In male broilers the poorest FCR was observed in group D followed by in groups B, C and A. The best FCR in male broilers was recorded in group A which was significantly better than that of treatment groups A and D, however non- significant difference between FCR of groups A and C was recorded. In female broilers, the best FCR was observed in birds fed diet C followed by those fed diets A, D and B, however, non- significant difference in FCR among diets was recorded. Non- significant (P > 0.05) differences in plasma alkaline phosphatase (AKP), alanine transferase (ALT), serum cholesterol, tri glycerides (TG) and non-esterified fatty acids (NEFA) levels among diets and between sexes were detected. Significant (P > 0.05) differences in serum uric acid among diets and between sexes were detected. Female broilers had significantly higher uric acid levels than male broilers. In male broilers fed diet A, plasma uric acid value was observed to be significantly higher than those fed diet D but it was not significantly (P>0.05) different from those fed diets B and C. In female broilers fed diet A, plasma uric acid concentration was significantly higher than those fed diets C and D, however the differences were observed to be non-significant. Significant (P?0.05) difference was observed between uric acid values both in male and female broilers fed diets B and D, however, female broilers fed diet C differed non- significantly (P?0.05) from those fed diet D. On overall basis, there was significant (P?0.05) reduction in uric acid concentration by addition of 7.5 percent algae in the diets. No gross pathological lesions were seen on internal and outer surfaces of gizzard and proventriculus and these were normal in size, however, the internal membrane of gizzard was darker yellow color in birds fed diets containing algae. No lesions were noticed on liver, spleen and intestines and liver and spleen were normal in size. Liver was also of normal color.
