Publisher: 1993Dissertation note: The buffalo is an important animal in the agriculture economy of our country and the most useful animal for many millions of poor people, especially those living in Asia.
So far, no definite studies with regard to the nutritional requirements of the buffalo at various stages of growth and production (meat and milk) have been conducted. The feeding of buffalo in the sub-continent is based on various cereals and cash crops and are generally subjected to various nutritional imbalances, as a result, the genetic potential with regard to growth and production (meat and milk) of buffalo is not fully exploited.
Thus there is a desperate need for determining the specific feeding requirements of the indigenous dairy buffalo. For the purpose digestibility and metabolic studies for various nutritional needs for growth, fattening and production are to be conducted. Thus the present study was designed to study the effect of different plans of nutrition on growth, efficiency of feed utilization and nutrients digestibility in Nili-Ravi buffalo male calves.
Twenty-seven buffalo male calves of 9-12 months of age were randomly divided into nine groups. Three different levels of protein and metabolizable energy (80, 100 and 120% of NRC, 1976 Standards for beef cattle) were incorporated in the nine experimental rations.
After the trial of 140 days, the buffalo male calves gained weight 102.67, 110.64, 90.33, 36.00, 73.33, 127,34, 98.67, 82.34 and 110.34 Kgs. in groups 1-9, respectively. Maximum growth was recorded in group 6 [CP 100% and ME 120% of NRC (1976) Standards for beef cattle). Weight gain was non-significant due to varying levels of protein in the rations while weight gain was significant (P<0.05) due to varying levels of energy in the rations. Maximum growth rate of 909 gms. per day in group 6 (CP 100% and ME 120%) was recorded. The regression equation for weight gain with the relation to protein and energy intake was as follows: Weight gain (WG) = -297.28 + .425 (Pr) ± 63.67 (En)
The feed consumption decreased with the increase of protein level in the rations while feed consumption increased with the increase of ME level in the ration but the effect was statistically non-significant.
Maximum feed was consumed in group 6 (CP 100% and ME 120%). It was observed from the study that dietary protein had significant effect on feed efficiency and it was improved with the increase of dietary protein in the ration. Feed efficiency also improved significantly with the increase of energy in the rations. It was noted from the study that the dry matter intake reduced with the increase of dietary protein but dry matter intake increased with the increase of ME level in the ration. The effect was statistically non-significant. Protein intake was significantly increased with increase of protein level while ME level in the ration had non-significant effect. ME intake was non-significant with the increase of protein level but it was significantly increased with the increase of ME level in the ration.
The digestibility of crude protein and ether extract increased with the increase of protein and energy level in the rations but the differences were nonsignificant. The digestibility of dry matter was increased at varying levels of protein and energy but the differences were significant (P<0.0l). The digestibility of NFE and crude fibre were also increased at varying levels of energy significantly (P<0.01) but these were low at 100% protein level than 80 and 120% protein level. It was observed that the digestibility of all the nutrients increased at high plan of nutrition (protein and energy).
It was concluded that protein requirements of buffalo male calves were the same as recommended for beef cattle NRC (1976) but metabolizable energy requirements were 20% higher than the recommended level for beef cattle, NRC (1976)

Publisher: 1993Dissertation note: A study was under taken to find out the incidence of hydatidosis and to evaluate the efficacy of indirect haemagglutination (IHA) test for the confirmation of natural hydatidosis in sheep slaughtered at Lahore municipal abattoir.
Blood samples from 200 sheep (50 each from hydatidosis affected and free sheep on the basis of postmortem findings and 100 blood samples Elected randomly without considering postmortem finding). The serum from each sample was separated, properly labelled and stored at -20°C.
For the preparation of antigen, crude cyst fluid was aspirated aseptically from hydatid cysts. Blood from healthy sheep was collected in 3.8% sodium citrate solution and red blood cells were separated by centrifugation. A 2.5% red cell suspension was prepared in Phosphate Buffered Saline (PBS). The sheep erythrocytes were sensitized by Hydatid fluid antigen. Optimal dilution of antigen 1:16 was used in Phosphate Buffered Saline (p11 6.4) for sensitizing the sheep erythrocytes. All the sera were inactivated at 56°C for half an hour and serial two f1d serum dilutions were prepared by micropipettes in microtitre U plates and sensitized erythrocytes were added to the plates and incubated at room temperature in a humid chamber for 3 hours. A titre of 1:32 and above was considered as positive. In positive reactions, the cells agglutinated like a carpet at the bottom of the wells where as in negative cases the cells settled as a compact mass in the centre of the wells. By the indirect haemagglutination test Ninety-two percent sheep were found positive for hydatidosis. (Table-4.2). Out of 50 serum samples (Group A2), 46 (92%) were confirmed positive on postmortem while 3 out of 50 (6%) hydatid free samples (Group A3), gave false positive results with IHA test.
It was concluded that indirect haemagglutination test is an accurate, reliable and sensitive test (92%) for the diagnosis of hydatidosis in sheep.
The blood cell counts (TLC, DLC) and blood chemistry (Total protein, A/G ratio) of the samples under investigation were also carried out. From the results it was evident that the hydatid cysts did not affect the blood values of the host significantly. However, only 28% of hydatid positive animals showed eosinophilia ranging from 7 to 23% which was non pathognomonic.
It was thus inferred that blood cell counts and blood c1vmistry of the hydatid cyst patients was of no diagnostic value.

Publisher: 1993Dissertation note: With rapid progress in commercial poultry farming the need to control poultry diseases, spirochaetosis is responsible for heavy economic losses with a mortalitry rate of 60 to 80 percent. (Mc Neil 1949).The disease is caused by Borrelia anserina and is of worldwide in distributed,whereever the tick Argas Percicus, which acts as the intermediate host is present.
This disease has characteristic symptoms of pyrexia, weakness,drowziness, anaemia, diarrhea, emaciation,paralysis, and finally death (Marcos et al 1946) The bfrdswhich survive remain weak,ariaemic, emaciated, and do not thrive well.This disease is of great economic importance in the poultry industry and it causes great financial ioss.It is therefore,inspective that an effective and economical treatment be devised to eradicate this problem.
This experiment.was conducted on 120 A grade day old chicks,which were reared under ideal hygienic condition.At the age of four weeeks the birds were divided into six equal groups, A, B, C, D, E and F with 20 bires in each respective group:
Group A (Non-infected , non-medicated
B (Infected and non-medicated)
C (Infected and medicated with Pencillin)
G (parenterally)
D (Infected and medicated with oxytetracyclin parenterally)
E (Infected and medicated with oxytetracyclin orally)
F (Infected and medicated with Amoxyclin Clomaxal orally)
Except for group A which was the control, all the remaining five groups showed the typical signs of the disease after 48 hours of in oculatiori.
In Group 13, the mortality rate was 40% ,Group C had a 20% mortality rate at 96 hours.Cure was l0O%.Group D had a 25% mortality and 100% cure at 96 hours post inoculation.Group E had a 30% mortality rate which was the highest of all the groups and curative rate 80%.The Group F had a 15% mortality which was the lowest record in all the six groups.It had 100% cuire at 96 hours.
From the results of this experiment it could be concluded that the 1\moxycillin (Clomoxal) was drug of choice. Penicillin G and Oxytetracycline (Terramycin orally ) showed the poorest results.

Publisher: 1994Dissertation note: The present study was conducted to find out the incidence of lungworm infestation, identify the different species and to observe the effect of mixed nematode infections on certain blood parameters in sheep and goats. The study was conducted at Parasitology Laboratory, College of Vety. Sciences Lahore. For this purpose sheep & goats brought to Lahore abattoirs for slaughtering were closely examined before and after slaughter and animals suspected for lungworms were selected for collection of blood and tissue samples. 200 samples of lungs and blood 100 each from sheep and goats were collected for parasitological and haematolog ical examination, respectively.
The results revealed that incidence of lungworms infestation in sheep and goats was 31 and 11 %, respectively. It was observed that Dictyocaulus filaria, Protostrongylus rufescence and Muellerius capillaris infection in lung of sheep was in the order of 22, 8, and 1 % respectively, whereas, the incidence of lungworms infestation in lungs of goats caused by the same species was 8, 3 and 0 %, respectively.
The highest incidence of lungworms infection observed was that of Dictyocaulus filaria in both the sheep and goats, while Muellerius capillaris was found only in lungs of one sheep and infection by this species could not be detected in goats.
The findings of this study showed that average red blood cell count, heamoglobin level and packed cell volume were reduced due to nematode infection in sheep and goats. The results have also indicated that nematode infection in sheep and goats enhanced erythrocyte sedimentation rate. From the results of the present study, it may be concluded that incidence of lungworm infestation in sheep and goats is on the higher side which warrants that suitable treatment and control measures should be adopted to safeguard our valuable livestock from this serious infection. It is also evident from the results that nematode infection adversly affects the components of blood in sheep and goats which may lead to anaemia and loss of growth and production.

Publisher: 1994Dissertation note: The study was designed to look into the immunogenic properties of Eimeria tenella. Two hundred and twenty five day old broiler chickens were reared under controlled conditions. They were equally divided into five groups i.e. A, B, C, D, and E. Group 'A' was kept as uninfected control. Group 'B' acted as infected control, which was infected with 50,000 sporulated oocysts at day 15, 25 and 35 of age. Group 'C' acted as infected and treated, which received sporulated oocysts on day 15, 25 and 35 alongwith 5 days treatment with salinomycine (60 ppm in finished feed) after 3 days of each primary and challenge dose. To group 'D' 1000 live sporulated oocysts were administered orally at day 3 and 10. Similarly, 'E' group received formalin treated 1000 sporulated oocysts orally at day 3 and 10 of age of chickens. Subsequently the members of group D and E received challenge infections of 50,000 Eimeria tenella sporulated oocysts at day 15, 25 and 35.
Immunogenicity was measured by the passage of oocysts per gm of faeces and by comparative weight gains amongst different groups. It was noticed that no coccidiosis could be established in groups A, C and E and the OPG counts remained nil throughout the period of experimnt. Group B showed high counts and group 'D' showed moderate ounts but towards the completion of experiment the OPG counts gradually reduced to 8400 and 6100 respectively, in both group.
Weight gains recorded were 473, 393, 316 and 310 gin. greater in A, E, D, and C respectively, as compared with group B. Group E depicted 1OC% protection and remained second to the uninfected control group A in respect of weight gains. Group 'D', although developed infection but due to acquired immunity became resistant to challenge infections and was placed 3rd in weight gain. Inspite of complete protection in group C due to Salinomycine treatment, the weight gains remained lower than group D and E.

Publisher: 1994Dissertation note: In this study 400 samples of blood obtained from different farms situated around Jaranwala, an important broiler raising area of Punjab, were examined serologically. The Newcastle disease virus titer in most cases were low and non protective against exposure to field strain. The birds had antibodies against pathogens such as Infectious bronchitis virus and Infectious bursal disease virus to which they had not received vaccine indicating the presence of field strain of these viruses in the area. Some of the birds at these farms had antibodies against Hycoplasma galliseplicum, Mycoplasnia svnoviae and Salmonella gallinarum. Poor hygienic conditions coupled with poor ventilation may lead to the rapid dissemination of these pathogens within a community of birds and cause severe economic problems.

Publisher: 1994Dissertation note: Pakistan has a large population of live stock, which plays an important role in the economy of the country. Parasitism adversally effects the growth and production of livestock. Great economic losses have been attributed to the sheep population in our country due to the parasitic infections including cestodes. A study of cestodal infections with taxonomy of the prevalent cestoctes species affecting sheep at different age groups in and around Lahore was conducted. The taxonomical study was conducted in the month of August, September and October, 1993. For this purpose 200 guts (one hurtdered each from below six month and above six month of sheep) were collected from Lahore Abattoir. Parasites were identitied under the microscope by preparing permanent mounts.
The over all incidence of cestodes infection in sheep was 65.5%.
The species of various genera of cestodes observed during the present
study were:
Moniezia pansa (64%), Moniezia benedeni (60%), Avitellina cjj[iur1ctta
(49.50%), Avitellina lahorea (40%), Avitellina sudanea (30%), Stilesia vittata
(30%), Stilesia globiounctata (50%) and Thvsanosoma actinioides (6%).
Monthwise prevalence of cestodes infection was also carried out and it was observed that the highest infection rate was (76%) during the month of August and (66.25%) during the month of September. While the lowest incidence was recorded as (57.14%) during the month of october, 1993.
The taxonomy of the prevalent cestode species was carried out. The effect of age of the animals on the intensity of cestodal infection was also studied. There was a significant difference in the prevalence of cestode infections among the two groups.
The present work was also aimed to verify the efficacy of two commonly available anthelmintics namely albendazole (valbazen) and niclosarnide (mansonil), in naturally infected stceep with Gastrointestinal cestocJes. Fifty sheep positive for cestods infections were randomly divided into two groups A and B, each group comprising of 25 animals. Group. A was given albendazole (valbazen) at a dose rate of 2.5 mg/kg body weight orally while the group B was administered niclosamide (mansonil) at a dose rate of 100 mg/kg body weight orally. The efficacy of both the drugs was evaluated on the bases of reduction of segments and number of eggs per gram of faeces after medication. The egg counts were made on zero, 3rd and 21st day. Both the drugs revealed a progressive decrease in the faccal egg/segment counts. The efficacy of albenclazole on 3rd and 21st day was 96.02 and 99.23% repectively while the efficacy of niclosamide (mansonil) was 100% on 3rd and 21st day.

Publisher: 1994Dissertation note: This study was carried out to investigate whether different dietary levels of vitamin E (recommended, deficient and excess) had any detrimental or beneificial effect on body weight gain, lymphoid organs, haemalotogical values, humoral response to NDV-vacci nation, eel I ular response to tuberculin and phagocytic activity of neutrophils of broiler chickens.
The study indicated that vitamin E supplementation 300 lU/Kg feed had beneficial effects on the weight gain of birds, weight of lymphoid organs such as bursa of fabricius, spleen, thymus and liver; feed intake and feed conversion ratio; serum antibody development against NDV vaccination; phagocytic index and delayed hypersensitivity index. Whereas, vitamin E deficiency adversely affects the body weight gain; weights of lymphoid organs such as bursa of fabricius, spleen, thymus and liver; feed intake and feed conversion ratio, serum antibody development NDV vaccination; Phagocytic index and delayed hypersensitivity index.
No significant effect of vitamin E supplementation/deficiecy was noted on haematological values.
From the results of this study it is concluded that vitamin E is not an immunosuppressive agent when used at recommended leavels or even in excess. Vitamin E deficient level in diet lowersthe immunocompetance of broiler chicken, whereas vitamin E excess level in diet improved immune responses and body weight gain.

Improvement In The Nutritive Value Of Fibrous Crop By-Products By Urea Treatment
by Rafaqat Ali | Dr. Nisar Ahmed Mian | Dr. Muhammad | Dr. Talat Naseer Pasha.
Material type: ; Format:
print
Publisher: 1994Dissertation note: Wheat straw and rice straw are two of the largest annually harvested crop by-products in Pakistan, and are commonly fed to buffaloes as well as cattle as a staple roughage source. These coarse roughages are essentially energy feeds in which the cell wall constituents may be as high as 80 percent of the total dry matter. However, productivity in ruminants given such straw diets is limited, primarily due to energy deficiency. Low digestibility and low nitrogen content of these roughages does not adequately satisfy microbial growth requirements, which are therefore major limiting factors responsible for poor efficiency of nutrient utilization.
In the present study, two fibrous crop by-products - wheat straw and rice straw, were treated with urea (as a source of ammonia), at 50 percent moisture level with or without added urease source at two different temperatures (220C and 390C) for three different periods (14, 21 and 28 days). Digestibilities of the treated and untreated feedstuffs were determined by in sacco technique. All the samples were chemically analysed for proximate as well as cell wall constituents before and after any treatment and after incubation in the rumen.
Increasing duration of urea-treatment invariably increased the crude protein content in all the treatments. At 28 days, difference between crude protein values of samples treated with urea alone or urea along with urease source was not statistically significant. Crude fiber contents of wheat and rice straw was inversely effected both by higher temperature and longer treatment period. Both mineral matter contents and ether extract values were not significantly effected by any of the treatment while NFE values were significantly reduced. Decrease in NDF and hemicellulose values after treatment was observed. Addition of urease hastened the process, though at 28 days, the difference between samples treated with or without the addition of urease was non-significant. Treatments increased the in sacco disappearance of DM, CF, CP, NDF, ADF and hemicellulose. Addition of urease and higher temprature increased the rate of change. Difference between urea treated and urea plus urease treatmed samples was relatively more marked in case of wheat straw than in rice straw, though in both the feedstuffs, it was non-significant at the end of treatment i.e., 28 days.

A Comparative Study Of Helminth And Haemoparasites Of Domestic And Wild Pigeons
by Asma Hussain | Dr. Mubashir Saeed Mian | Dr. Asif Rabbani | Dr. Muhammad | Faculty of Veterinary Sciences.
Material type: ; Format:
print
Publisher: 1995Dissertation note: There is an increasing interest in pigeons and other game and ornamental birds. These birds are generally kept either free roaming or confined in outdoor pens and hence are vulnerable to various parasitic infectious, which greatly effects the productivity of these birds.
The meat production of the pigeons can be improved by controlling disease problems particularly helrninths and blood protozoan infections, so that in near future they may contribute towards narrowing down the animal protein supply gap by substituting poultry meat with squabs.
The present work was planned for the comparative study of helminths and heemoparasites of domestic and wild pigeons. For this purpose 300 each of guts and blood smears were studied. The overall incidence of gastrointestinal helminths and blood protozoans was 77.33% and 31.99% respectively, while 36% of birds had mixed infection. The incidence of gastro-intestinal helminths and blood protozoa in wild pigeons was 89.33 and 20.66 percent respectively and in domestic pigeons it was 65.33% and 11.33% respectively. Whereas mixed infections were 22% and 14% respectively.
The following species of helmitiths and blood protozoa were recorded and identified.
1. Raillietina tetragona
2. Raillietiiia cesticillus
3. Choanolaenia infundibulum
4. Ascaridia colurnbae and
5. Cap illaria obgnata
The two species of blood protozoa recovered were:
1. Aegypanella pullorum and
2. Haeiçotuscumbae
Among the helrninths recorded, cestodes were found predominating as compared with nernatodes in both wild and domestic pigeons. Raillietina cesticillus was the most common cestode species in both Wild and domestic pigeons i.e. 51 and 33 percent respectively while Asci colurnbae predominated the nernatode species i.e. 18 and 15 percent respectively. The Incidence was higher in wild pigeons.
Aegyptianella pullorum was more common blood protozoan i.e. 22 and 11 percent respectively in wild and domestic pigeons. The incidence of Haemoproteus clumbae was 9 and 11 percent respectively.

Publisher: 1995Dissertation note: After an outbreak of a vesicular disease in Lahore District a demoninator based active surveillance was conducted in four villages. During and after the epidemic and the homesteads were visited and interviewed from door to door. The total number of animals kept by the farmers (N = 1537) and the affected number of animals (n= 1384) by age, sex and species were enquired from the farmers and recorded on a questionnaire proforma. The clinical signs of the affected animals and their sequence were recorded.
Epidemiological investigations revealed that morbidity rate of 66.94% (n=867/1537) was higher in buffaloes than cattle which was 48.34% (n=117/242). Young animals of both species were more susceptible than adults. Morbidity rate in young cattle was 50.64% (n=39) in 77 animals but in case of adult cattle amongst the total population of 165 morbidity rate was 47.27% (n=78). In case of young buffaloes 290 (69.37%) out of 418 animals while in case of adult buffaloes morbidity rate was 63.51% (557/877). Case fatality rate was observed higher 42.85% (363/847) in buffaloes than the cattle which was 26.65 % (37/117). Frequency of clinical signs observed was found as depression (63.30%), mucosa diffusely red (61.87%), anorectic (61.48%), muzzle hyperimic encrusted (61.09%), erosions (58.49%), laminitis (56.73%), temperature 101-105°F (54.26%), drooling (53.35%), shivering (44.82%), mistitis (38.51%), temperature 105-107°F (6.18%), polypnea (5.79%), temperature 101-103°F (4.35%), cough (3.38%), diarrhoea (2.40%), subnormal (0.71%) and abortion (0.65%).
In this project 160 animals affected from the disease, 80 of each species, were selected for hematological and serological investigations. Forty healthy animals were observed as control.

Publisher: 1995Dissertation note: The present study was carried out to know the comparative efficacy of different IBD vaccines including Rhone Merleux, Solvay, TAD and CVS in broiler chickens. The evaluation was based on the immune response developed against the vaccine concerned and its assessment through agar gel precipitation test (AGPT) and indirect haemagglutination (IHA) test.
All the birds prior to their vaccination were examined for the presence of passive immunity, both through AGPT and IHA. AGPT could only detect 60-80% birds for maternal immunity, whereas IHA showed the presence of this immunity in all the experimental birds.
All the vaccinated groups were examined for their immune response on 7th, 14th and 21st day post-vaccination. Both AGPT and H-IA showed the decline in immunity on 7th day post-vaccination and then a gradual increase in titres occurred at 14th day of vaccination. The titres attained their peak on 21st day post-vaccination.
With AGPT on 21st day post-vaccination the birds for various vaccines gave precipitin lines respectively as 76, 89, 93 and 100 per cent, for Rhone Merieux, Solvay,TAD and CVS vaccines.
With IHA the highest titres obtained on 21st day post- vaccination was 1:128 for each vaccine, however, the number of birds giving this titre varied being only one bird for Rhone Merleux, Solvay , TAD and 3 birds from CVS. Nevertheless, the next best titre obtained was 1:64 and the number of birds giving this titre was 2, Nil, 2 and 8 birds from Rhone Merieux, Solvay, TAD and CVS. The predominant number of birds, vaccinated against each vaccine developed a titre of 1:16 observed at 14th day and 21st day post- vaccination.
The challenge infection results showed that birds with lilA titres of upto 1:4 developed severe lesions on their bursae, and other parts of the body, alongwith giving less BBR values. In this way the better IHA titre gave protection to the birds against a challenge infection.
All the four vaccines gave identical results for their efficacy against the IBDV infection, however, CVS vaccinated birds developed highest titres in greater number.

Publisher: 1995Dissertation note: Two long acting antibiotic preparations of oxytetracycline and amoxicillin were used in these trials against Haemorrhagic Septicaemia, singly and alongwith a combination of synthetic glucocorticoids (Dexamethasone and prednisolone).
Eighty buffalo calves suffering from Haemorrhagic Septicaemia were selected and treated under field conditions. Weighted clinical score was recorded before and after treatment in each case, on the basis of severity of clinical symptoms. Reduction in this score and recovery or death of animal was also noted.
It was concluded that amoxicillin was more effective than oxytetracycline and the addition of glucocorticoids reduced the convalescence period and also increased the survival rate. Therefore long acting amoxicillin alongwith Dexamethosone and prednisolone is recommended as the successful therapy for Haemorrhagic septicaemia.

Evaluation Of Uretero Jejunocolostomy For Urinary Diversion In The Dog
by Aneeta Hussain | Dr. Mazhar Iqbal | Dr. Muhammad | Dr. Muhammad Arif Khan | Faculty of Veterinary Sciences.
Material type: ; Format:

Publisher: 1995Dissertation note: Urinary diversion is the procedure adopted for urine expulsion in the most natural way, in the absence of the urinary bladder. In the beginning of the twentieth century many surgeons of human side as well as veterinarians used intestines for performing urinary diversion. They adopted many methods for this purpose but only a few were found to be successful. These procedures were used to relieve the animal from malignant bladder carcinomas, severe damage of bladder and urethra during accidents, and extrophy of urinary bladder etc. These diseases mostly cause urinary discomfort, incontinence of urine and painless heamaturia and cystectomy becomes a necessity.
During this study fifteen healthy dogs of either sex were used. Laparotormy was performed under aseptic precautions. The small intestine was exteriorized through. the incision and the terminal portion of jejunum was identified. A 6-8 cm portion of the jejunurn was selected and milked to clear it of from the feacal materials. This portion was isolated from rest of the intestinal tract with the Doyen's intestinal clamps and was cut off with its mesenteric blood supply remaining intact. The continuity of the small bowel was restored by end to end anastomosis. The vent in mesentery was closed by simple continuous sutures. The isolated Jejunal segment was wrapped in a piece of gauze soaked in normal saline.
The urinary bladder was emptied in females by gentle digital pressure and in males by mean of a disposable syringe. The ureters were amputated obliquely down to the trigone area and bladder was excised. Afterwards one end of the Jejunal segment was closed by lambert sutures. A small hole was created on the right side at the upper third portion which cut through the first three layers. From this hole a 2 cm long submucosal tunnel was created going towards the open end of the segment. The cut end of the ureter was sutured to the mucosa of the Jejunal segment using 3/o prolyene simple interrupted sutures. On the left side of the segment the other ureter was implanted similarly.
A longitudinal incision equal to the diameter of jejunal segment was made at the antimesenteric border of the distal portion of colon. The open end of jejunal segment was implanted here using 3/0 chromic catgut via side to end anastomosis with simple I nierrupted crushing sutures, thus creating an intestinal bladder. Finally the abdomen was closed in routine manner. It was concluded on the basis of this study that:
1. Viable segment of small bowel with blood and nerve supply intact can be used as a bladder.
2. Voiding occurs in the most natural possible way without any need of an external reservoir.
3. There was no ascending infection, so kidneys remained normal.
4. Use of antibiotics for rest of the life was not needed.
The successful attempt of making a new bladder strengthened the belief in cases where there was no other way of saving the animal's life except surgical intervention. So the veterinarian should involve himself with the core of his heart in the operative procedure with the aim of achieving good results. Whether he loses or gains, he must have a satisfaction of being loyal to his profession.

Publisher: 1995Dissertation note: Late maturity in buffalo is one of the major problem which limits its overall productive and reproductive performance. Summer anoestrus plays role to delay the onset of puberty. The present study was therefore conducted to induce oestrus in non-cycling buffalo heifers during summer. Eighteen healthy non-cycling buffalo heifers with 431.38±41.5 kg body weight and 1190.44±170.92 days of age were utilized. These animals were randomly divided into three equal groups viz; group A, B and C; each comprising of 6 animals. Heifers in group A were inserted an ear implant containing (3 mg norgestomet) for 9 days and an injection of oestradiol valerate at implant insertion. At implant withdrawal 700 IU of PMSG was administered intramuscularly. Later these animals were inseminated twice at 12 and 20 hours after the onset of oestrus. The heifers in group B were given 2 injections of 500 pg cloprotenol (2 cc estrumate) at 11 days interval and were given fixed time insemination at 72 and 96 hours after second injection. The heifers in group C received no treatment and served as controls. The animals in oestrus from group C were inseminated at 12 and 20 hours after the onset of oestrus. The rectal palpation was performed for ovarian structures twice in a week for two consecutive weeks and at oestrus for follicular development and on day 8 and 10 after oestrus for corpus luteum. Pregnancy was diagnosed on day 60 post insemination. Blood samples were collected on day 8 and 10 after oestrus for progesterone estimation. Progesterone concentration was estimated by enzyme immuno assay technique. All the heifers in group A exhibited oestrus within 49.83 ± 12.65 hours; after PMSG injection. No animal from group B exhibited oestrus whereas only one heifers from control group C exhibited oestrus. The duration of oestrus in buffalo heifers treated with Norgestomet ear implant was 18.00 ± 0.30 hours. The only heifer from group C remained in oestrus for 20 hours. Only one animal (16.66%) conceived at induced oestrus in group A. None of the animal from group B and C became pregnant. Progesterone levels were found to be indicative of ovarian activity in experimental animals. Plasma progesterone concentration of 0.61 ± 0.16 ng/ml was observed on day 8 and 10 in animals showing inovulatory oestrus from group A whereas progesterone values of 5.2 and 0.7 ng/ml were observed in ovulating animals, exhibiting the presence of active corpus luteum. Low progesterone levels of 0.62 ± 0.17 ng/ml were observed in heifers from group B showing the non functional status of the ovarian. Plasma progesterone levels of 5.2 and 7.5 ng/ml was observed on day 8 and 10 after insemination in the only heifers from the control group C. The remaining 5 animals were having smooth ovaries with basal levels of plasma progesterone (0.53_+ 0.9ng/ml). In conculsion Norgestome treatment was found to be effective for induction of oestrus in buffalo heifers during summer. However studies whoud be undertaken to determine the reasons of lower conception rate. Prostaglandin (PGF2a) treatment was found ineffective in noncycling true anoestrus buffalo heifers.

Publisher: 1996Dissertation note: Nature has blessed Pakistan with a large population of livestock which play an important role in the economy of the country. Parasitism adversely effects the growth and production of livestock. Great economic losses have been attributed to the sheep population in our country due to parasitic infections including gastro-intestinal parasitism. A study of gastro-intestinal parasitism with isolation and identification of the parasite species affecting sheep at different age groups in and around Lahore was conducted in the months of July, August, September and October, 1994.
For this purpose 200 G.I. tracts of sheep (One hundred each from below six months and above six months of age) were collected from Lahore Metropolitan Corporation, Abattoir.
The overall incidence of gastro-itestinal parasitism in sheep was found to be 68.5%. Age group wise incidence was found to be 71% and 66% in sheep below and above six months of age respectively. Classwise overall incidence was found to be Sporozoan (51%), Trematodes (21%), Cestodes (62%) and Nematodes (68%).
Age group wise incidence of Sporozoan, Trematodes, Cestodes and Nematodes was found to be 60% and 42%, 12% and 30%, 71% and 53%, 73% and 63% in sheep below and above six months of age.
Month-wise prevalence of gastro-intestinal parasitism was also carried out which was higher in the month of August and lowest in the month of October. Nineteen different species of Parasites were recorded which are detailed as under:
1. Eimeria arloingi
2. Eimeria ninakohlvakimovae
3. Eimerla parva
4. Elmerla intricata
5. Eimeria faurei
6. Paramphistomum cervi
7. Cotylophoron cotvlophorum
8. Moniezia. expansa
9. Moniezia benedeni
10. Avitellina centripunctata
11. Haemonchus contortus
12. Oesophagostomum colunThianum
13. Oesophagostonim venulosum
14. Trichuri
15. Ostertagia circumcincta
16. Ostertagia ostertagi
17. Chabertia ovina
18. Trichostrongvlus colubriformis
19. Nematodirus spathiger
The isolation and identification of various collected parasites was carried out. The relationship between the age of sheep and the occurrence of gestro-Intestinal parasitism was also studied. There was a Non Significant difference in the prevalence of gastro-intestinal parasites among the two groups.
The present project was also aimed to observe the effect of single or multiple parasitism on certain haematological parameters like, estimation of haemoglobin contents, total erythrocytic count, total leukocytic count, erythrocyte sedimentation Rate, packed cell volume and differential leukocytic count.
These heamatological studies were carried out on control (parasitic free) and parasitised sheep of below and above six months of age.
The findings of haematological studies showed that there was decrease in haemoglobin contents. total erythrocytic count, packed cell volume, total leukocytic count and increase in erythrocyte sedimentation rate in both sheep below and above six months of age under the effect of single or multiple gastrointestinal parasitism. The values of differential leukocytic count were variable in both age groups.
Most of the haematological disturbances on various blood parameters in both age group of sheep were proved to be statistically significant.
From the results of the presents study, it has been concluded that the incidence of gastro-intestinal parasitism in sheep below and above six months of age is on the higher side which warrants that certain essential preventive measures must be adopted to safeguard our valuable livestockfrom these serious parasitic infestations. It is also evident from the results that gastro-intestinal parasitism adversely affects the blood components in sheep which may lead to anaemia, loss of growth and loss of production.

Publisher: 1995Dissertation note: The project was designed to study the effect of enzyme (Kernzyme) supplementation on the performance of two broiler strains (Hubbard and Arbor Acres). One hundred and twenty day old chicks of each strains were purchased from respective hatcheries, The starter rations were fed upto 28 days and finisher rations were fed upto 35 days. Non-significant difference was observed between control and enzyme supplemented rations in weight gain, feed consumption and feed efficiency. Whereas significant. difference was observed in weight gain and feed consumption between the broiler strains. While non-significant difference was observed in feed efficiency between the strains. A significant difference was observed between broiler strains, control arid enzyme supplemented rations in dressing percentage. A non-significant difference was observed in chemical composition (moisture, protein and ether extract.), of lean breast meat. between broiler strains, control and enzyme supplemented diets.
The study revealed that Kemzyme supplementation did not. improve the performance of broilers. Whereas Hubbard strain has significantly (P<O.O1) higher weight. gain, feed consumption and dressing percentage than Arbor Acres. While Kemzyine supplementation has significant difference (P<O.05) in dressing percentage.
The economic evaluation of the study revealed that Hubbard was the most economical than Arbor Acres strain. The cost of one kg live weight was lowest for Hubbard i.e. Rs.22.05.
The control ration was the economic ration in this experiment. By supplementing the enzyme, the cost of ration was increased and cost of producing the live weight by enzyme supplemented ration was increased as well. The results of the present study proved that the use of Kemzyme is uneconomical and Hubbard strain is the better strain which behave perfectly well Pakistani environmental condition.

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.

Effect Of Different Levels Of Protein And Salt On Water Metabolism In Broilers And Layer Chicks
by Faisal Gulzar Ahmad | Dr. Nisar Ahmed Mian | Dr. Jaweed Ahmed Qureshi | Dr. Muhammad.
Material type: ; Format:
print
Publisher: 1995Dissertation note: Wet litter in poultry houses is a problem of considerable economic and pathological importance; This is due to the excessive elimination of water in the droppings and that contained in the expired air of the birds. As a result of this excessive moisture the litter becomes wet which in turn encourages the development of various diseases, unnecessary increase in labour and managemental hazards/expenses. Wet litter also encourages fly development, reduces beneficial bacterial population and creates problems in manure handling and removal.
A solution of the problem of wet litter would thus involve determination of those factors responsible for the elimination of excessive amounts of water via renal and alimentary routes. One of these causal factors is diet. The present study was designed to determine the effect of sodium chloride and certain dietary protein levels on water intake, feed consumption, moisture content of various organs as well as that of droppings.
Experiment was conducted at the department of Animal Nutrition, College of Veterinary Sciences, Lahore for a period of 8 weeks. Two hundred and seventy day- old chicks each of broiler and layer were randomly divided into six groups i.e. B1, B2 B3, B4, B5, B6 (Broilers) and L1, L2, L3, L4, L5, L6 (Layers) of 45 birds each. Each group was further subdivided into three replicates of 15 birds each. These groups were assigned randomly to six experimental rations having 20 and 23 percent crude protein and salt supplementation of 0.0, 0.75 and 1.0 percent level. Weekly feed consumption, weight gain and water intake were recorded. Moisture contents of crop, intestine, caecum, carcass as well as that of droppings were determined at the end of 4th and 8th weeks of age. Abdominal fat contents of broilers and layers were also recorded at the end of 4th and 8th weeks of age.
In broilers, the feed conversion ratio was significantly (P<0.05) affected by the level of salt supplementation. At 20 percent crude protein level, F.C.R. improved from 2.60 to 2.41 when the salt supplementation was increased from 0.0 to 0.75 percent. But the best F.C.R. (2.33) was obtained at 23 percent crud protein with 0.0 percent salt supplementation level. However, feed efficiency decreased at both the protein levels when level of salt supplementation was increased to 1.0 percent. The feed consuption within the group was not significantly (P<0.05) affected by the increase in crude protein level from 20 to 23 percent or by increae in the level of salt supplementation both for layers and broilers. In layers, the weight gain, feed consumption and F.C.R. followed a similar pattern as was seen in broilers.
Increase in the level of protein and salt supplementation in the ration increased the water intake of both the broilers and layers, though the difference was statistically non-significant. However, level of salt supplementation had a significant (P<0.O 1) effect on water intake and water-feed ratio.
At 4 weeks of age increase in level of salt supplementation at both the protein levels significantly (P<0.01) increased the faecal moisture percentage. Results of the statisical anlysis of the data at the end of 8 weeks were similar to those obtained at the end of 4 weeks.
It was observed that increased moisture contents of intestines lead to increased moisture in. the faecal material. At the end of 8th week the intestinal moisture content was significantly affected as result of increase in protein and salt levels.
The caecum is the chief site for water reabsorption in birds, and water contents of caecum have direct bearing on the faecal moisture and in turn on the wetting of litter. At 8 weeks of age, borth the protein levels did not exert a significant (P>0.05) effect of protein levels on the caecal moisture contents. Change in the caecal moisture contents as a result of increase in level of salt supplementation was also non-significant (P>O.05). Salt supplementation level significantly (P<0.01) increased the carcass moisture percentage. At the end of 8 weeks all the three factors and their interactions, except breed and salt interaction were significantly (P<0.0 1) different.
At the end of 4th and 8th weeks the abdominal fat contents did not show any significant pattern which could be correlated specifically with salt or protein levels. At the end of 4 weeks all the factors and their interactions except breed and protein interaction significantly (P<0.0 1) affected the abdominal fat contents. At the age of 8 weeks all the factors and interaction had significant (P<0.01) effect on abdominal fat contents.

Publisher: 1993Dissertation note: Cases of rupture of urinary bladder, cystectomy for carcinoma of the bladder or urethra and extrophy of urinary bladder are all important conditions in which urinary diversions is recommended. Many surgeons in madical field as well as Veterinaians have had tried and reported various corrective surgical procedures. In the past several attempts have been made in which the bladder was excised and ureters were implanted in colon (large intestine). But satisfactory results were not obtained because the bacterial count in the colon is much higher which resulted in ascending infection towards kidneys and caused Hydro-nephritis, pylonephritis or gastro-intestinal disturbances (1979, Boree).
Beside these complications, the advantage of this surgery was that the animal would be cured from all those diseases of urinary bladder or urethra which do not respond to other form of therapy. However, the aforementioned problems of pyelonephritis etc. and the life long cover of antibiotics to combat them. Thus compels the clinician to think of some better procedures, a new project comprising ureterojejunostomy and ureterogastrostomy was designed.
Eighteen healthy dogs of both sexes were used for this experimental implantation of ureters in the stomach (pyloric antrum) into the mid and distal jejunum. The urinary bladder was emptied by gentle digital pressure and excised completely after amputating the ureters obliquely down to the trigone area. The cut ends of the ureters were wrapped in sponge moistened with saline. An entrotomy incision about 5 ems long was given on the selected segment of mid or distal jejunum 10 ems cranial to this incision a small nick in between the mesenteric and antimesenteric border was made going through the first three layers. Through the nick 1.5 cm submucosal tunnel was created going towards the entrotomy incision. The ureter was pulled into the lumen of the intestine through this tunnel. The cut end of the ureter was spatulated and sutured to the intestinal mucosa using 3/0 prolyene simple interrupted sutures. The other ureter was similarly implanted on the other side of the jejunum. With the help of a probe the patency of ureter was checked and entretomy incision was closed using 2/0 chromic catgut simple interrupted crushing sutures. Finally the abdomen was closed in routine manner.
In the dogs of group No.3 the ureters were implanted in the least vescular part of the pyloric antrum through gastrotomy incision using the same procedure explained above.
It was concluded on the basis of this study that:
1) Pressure within the jejunum and stomach interfered with drainage and forced air, food particles and organisms up to the renal pelvis.
2) As the stomach and jejunum were acting as reservoir and the urine was in contact with the wall for a longer period, reabsorption of urinary solutes occured and resulted in azotemia.
3) The typical changes were hyperchloraemic acidosis with potassium depletion and this occured in every patient with uretro-jej unostomy and uretero-gastrostomy diversion.
4) When severe the patient developed loss of appetite, weakeness, thirst, listless, coma and died.

Publisher: 1996Dissertation note: The study was designed to find the prevalence and intensity of liver fluke infection in buffaloes in Lahore District. The study period was from April 1995 to July 1995. The data was based on:
Data collected from four Veterinary Hospitals in Lahore District namely, Herbenspura, R.A. Bazar, Shamkey Bhattian and Rukh Chandra indicated that during the study period from 1 April, 1995 to 31 July, 1995, a total of 2184 buffaloes were treated for different diseases in these hospitals. Based on history, clinical symptoms and response to treatment 229 (10.48%) buffaloes were positive for fascioliasis.
Information collected from Municipal Corporation, Lahore abattoirs regarding economical losses revealed that one hundred eight million rupees were lost annually due to damage and condemnation of liver fluke infected livers.
Two hundred faecal samples collected directly from the rectum of buffaloes from various localities at Lahore were examined microscopically by fresh smear and sedimentation methods, which revealed that 75 (37.5%) buffaloes were suffering from fascioliasis.
In order to determine the intensity of Fascioliasis in infected animals, quantitative faecal examination was done (and it ranged from 32.6 to 45.6 EPG indicating that the disease is likely to be pathogenic).
Overall liver fluke infection was recorded by examining forty livers along with their bile ducts collected from slaughtered buffaloes and it was found that 16 (40%) had liver fluke infection.
Identification of live flukes from the infected flukes revealed that 8 (50%) had mixed infection of Fasciola hepatica and Fasciola gigantica, 5 (31.25%) had only Fasciola gigantica infection while 3 (18.75%) had only Fasciola hepatica infection.
It was concluded from the above studies that Fascioliasis in buffaloes in Lahore district is quite prevalent, and it needs to adopt appropriate measures to control the infection.

Publisher: 1997Dissertation note: The project was designed to study the effect of Doxin on the 1.txuxuine system and if any, its toxicity (in normal and excessive doses) in broiler chickens. A total number of' 150 day old broJer chicks were randomly divided into six equal groups, A through F, each containing 25 birds. Group A arid B were kept as control i.e. A was non-medicated (Doxin) and vaccinated against ND while B was non-medicated (Doxin) and non vaccinated against ND. Groups C and E were medicated I)oxin at different levels (0.5gm/I and 4 gm/I) at 1st to 5th day and 22nd to 26th day respectively. Both groups were vaccinated against ND. Groups D and F were medicated Doxin at different levels (0.5gm/i and 4 gm/i) at 1st to 5th day and 22nd to 26th day respectively, both groups were non vaccinated against ND. The experimental period was 42 days. Organ body weight indices, gross lesions on liver, spleen, thymus, bursa of Fabricius and kidneys, determination ol immune response against Newcastle disease, serum total protein, albumin, globulin, A/G ratio, alkaline phosphatase, alanine amino transferase, aspaitate amino transferase, uric acid and urea levels were conducted.
The statistical analysis of organ body weight index for liver showed significant difference between the medicated and nonmedicated (control) groups. The highest. liver body weight index was achieved in the birds of group E. The organ body weight indices of spleen, thymus and bursa of Fabricius are quite irregular. The data obtained by the the analysis of serum statistically indicated that the mean levels of serum total protein and albumin of control and medicated groups were not significantly different from each other. The mean levels of Globulin, A/G ratio of vaccinated and non- vaccinated groups carry statistical significant difference. There was no significant difference in alkaline phosphatase (ALP), alanine amino transferase (ALT) and asparate amino transferase (AST) levels of all medicated and non-medicated groups. The mean levels of urea and uric acid were increased in the medicated groups, highest in the high dose medication. The data obtained by the analysis of antibody titre against Newcastle disease on 0, 14th, 28th and 42nd day of experiment showed that geometric mean HI titres of all medicated groups decreased that of control groups.

Influence Of Various Treatments Of Rice Polishings On The Performance Of Broiler Chicks
by Abdul Majid | Prof. Dr. Nisar Ahmed Mian | Dr. Javaid Ahmed Qureshi | Dr. Muhammad.
Material type: ; Format:

Publisher: 1997Dissertation note: Increasing cost of feed ingredients and use of cereal grains in poultry feed which are also used for the human feeding, makes it imperative to look for alternative sources for feeding poultry to save grains for human consumption and reduce the cost of feed as well. Ingredients which are cheap, not utilized for human feeding and are readily available, merits consideration for poultry feeding. Rice polishing is one of such ingredient.
Rice polishings is an important by-product of rice milling industry. It is a finely powdered material obtained in polishing the rice kernels after removal of hulls and bran. It furnishes almost equivalent energy as other cereal grains and is a good source of protein and water soluble vitamins specially thiamin and niacin. It however contains certain antinutritional factors which, could be eliminated by various treatments yielding it into a useful feed ingredient for poultry feed.
Present experiment was conducted to observe the influence of rice polishings on the performance of broiler chicks after subjecting it to various treatments. Full fat rice polishings was subjected to extrusion cooking and then divided into 4 equal parts. One part was used in ration as such, second treated with 1 percent acetic acid, third treated with 1 percent calcium hydroxide and fourth treated first with acetic aid and then with calcium hydroxide. Five starter and finisher experimental rations designated as A, B, C, D, and E respectively were prepared. Ration A contained no rice polishings and was kept as control. In rations B, C, D and B treated rice polishings at 15 percent level was used substituting wheat. Starter rations were fed for 35 days and Finisher rations for 21 days to 150 Hubbard broiler chicks divided into 15 experimental units of 10 chicks each reared on floor on deep litter system. Each experimental ration was randomly allotted to 3 experimental units of chicks. Results indicated that maximum weight gain was recorded in birds fed on ration C which contained extrusion cooked rice polishings treated with 1 percent acetic acid. Lowest weight gain was recorded in birds fed on ration A (control). Second best result in weight gain was observed in birds fed on ration D which contained extrusion cooked rice polishings treated with 1 percent calcium hydroxide.
Best feed utilization per unit of gain was observed in birds fed on ration C where as poor feed conversion ratio was noted in birds fed on ration E which contained rice polishings first treated with acetic acid and then with calcium hydroxide.
Results indicated that different treatments improved the nutritional quality of rice polishings and resulted into better weight gain. Use of treated rice polishings did not show any detrimental effect on the performance of birds. Difference in feed consumed and conversion ratio towards higher side might have been due to some managemental errors or weather conditions. Extrusion cooked rice polishings treated with 1 percent acetic acid showed significantly improved growth rate and feed utilization in birds per unit of gain as compared to control and other rations containing rice polishings given other treatments.
It was concluded that various treatments improved the nutritional quality of rice polishings and it proved to be a beneficial feed ingredient for poultry feeding substituting wheat without any deleterious effect. Treatment with 1 percent acetic acid or 1 percent calcium hydroxide were equally good and potent methods to overcome the problem of antinutritional factors present in rice polishings.

Publisher: 1998Dissertation note: A study of gastro intestinal helminth parasites of sheep and goats of District Peshawar has been conducted, covering a period of 4 months (May to August, 1998). During this study incidence of GIT. helminths and their impact on production potential (weight gain) of sheep and goats was studied. Random collection of samples were made from Peshawar slaughter house and a total of 40 guts each in sheep and goats were examined and following species of helminths were recovered and identified. Oesophagostomum columbianum, 0. venulosum, Trichuris parvespiculum, Haemonchus contortus, Chabertia ovina, Bunostornum trigonocephalum, Nematodirus spathiger, Moniezia benedeni, Moniezia expansa, Trichuris lani, T. globulosa, Cysticercus tenuicollis.
Only two species of cestodes and nine species of nematodes were recorded during the study. However no trematode specie was recorded. Amongst the nematodes Trichiurisparuespiculum infection was recorded to be the highest in sheep and goats with an incidence of 64.70% and 73.33% respectively. The incidence of Haemonchus contortus was 24.19 and 53.33% in sheep and goats respectively. The worm burden ranged from 1-470 in sheep and 3-141 in goats respectively.
Out of total gastro intestinal tracts examined (40 each in sheep and goats), 73.33% and 60.29% were found positive for mixed infection in sheep and goats respectively.
In order to assess the effect of GIT helminths on live weight gain and its measurement in terms of economics of the above mentioned animals, 0 Hasthnagri sheep and 30 beetal goats were divided into two groups (control vs. treated by Nilzan Plus of ICI). The average daily weight gain in sheep group was 83.78 gms while in goats it. was 85.26 gms per animal. On comparison with treated group, the increase weight gain was 3.03 kg and 2.56 kg in sheep and goats respectively at the end of the experiment. Calculating the increase on live weight basis Rs.234.5 and 158 per animal were earned more in sheep and goats respectively. After deducting the cost of anthelmintic treatment the net gain Rs.222.5 and Rs.146 per animal in sheep and goats. During this study a progressive decrease in faecal egg counts with increasing age was observed both in sheep and goats.
Statistical analysis by using un-paired "t" test confirmed that there was significant differences in weight gain and faecal egg counts, between control and treated groups of sheep and goats.

Publisher: 1998Dissertation note: The phosphorus availability in broiler ration was improved by the supplementation of phytase enzyme. A unit of phytase is defined as the quantity of enzyme that liberates LU. mol of inorganic P/mm. from 5.1 mm sodium phytate at pH 5.5 and 37°C. Six weeks old forty (40) broiler birds were housed in individual cages in a room maintained with standard conditions. Birds were randomly divided into four groups having 10 birds each including control group. The following level of phytase were used 0, 300 U, 600 U, and 900 U. A preliminary period of 7 days was observed to remove the effect of previous diet and then feed intake and production of excreta was measured quantitatively per pen over three consecutive days.
By the supplementation of the different levels of phytase enzyme the P availability was significantly (P<0.01) increased in different groups. Maximum phosphorus availability was achieved in D groups similarly minimum P availability was achieved in A group (control). rphe data was statistically analyzed by using the complete randomized block design highly significant (P<0.01) difference was observed in various rations. For the comparison of means DMR test was applied which showed significantly (P<O.O1) higher P availability in ration D as compared to the remaining rations (A, B and C). The control ration was economical ration in this experiment. By supplementing phytase the cost of the ration was increased. rrhe results of present study proved that use of phytase is uneconomical but maximum phosphorus availability could be achieved by using the phytase enzyme in poultry rations.

Publisher: 1998Dissertation note: This project was designed to investigate the effects of two anticoccidials Ampisol 20% and Esb3 30% with and without supplementation of vitamins (A, D3, E and K3 as "Symodek") on the immune system of broiler chickens. To evaluate such effects the parameters used for study were; effects, on the weights of immuno regulatory organs (bursa of Fabricius, thymus, spleen and liver), organ body weight indices, histopathology of primary lymphoid organs (bursa of Fabricius and thymus), total and differential leukocytic counts, total serum protein, albumin globulin ratio and immune response to Newcastle disease virus vaccination. A total of 120 chicks, divided into 5 equal groups viz A to E were reared for 42 days. Groups A, B, C, and D were medicated with, Ampisol 20%, Ampisol 20% + Symodek, Esb3 30%, and Esb3 30% + Symodek, respectively while group E was kept as control(no drug medication). All the birds were vaccinated with ND virus vaccine on day 7th and day 2 1st. All the medication, was done through drinking water at the recommended prophylactic dosage levels.
The study revealed that Ampisol 20% had favourable effects on the weights of immunoregulatory organs, and organ (bursa of Fabricius, thymus, spleen and liver):bodyweight indices. Esb3 30% had negative effects on these parameters.
Histological studies of primary lymphoid organs (bursa of Fabricius and thymus) revealed no detrimental effects of different medications except in birds of group C and D given Esb3 30% or Esb3 30% + Symodek, where slight degenerative changes were noted in bursae and thymi.
On day 42 the mean TLC values were slightly lower in birds medicated with Esb3 30% as compared to birds which received Ampisol 20%. On day 42 the mean lymphocytic percentages were higher in groups medicated with Arnpisol 20% as compared to those given Esb3 30%. Vitamins supplementation exerted favourable effects on TLC and DLC values. This study further indicated that mean total serum protein (TSP), mean serum albumin, mean serum globulin and mean A/G ratios were higher in birds medicated Ampisol 20%, than those medicated Esb3 30%. Vitamin supplementation had augmenting effects on these values. On day 28, 35 and 42 the antibody titres in birds medicated with Ampisol 20% were higher than those given Esb3 30%. Vitamin supplementation exerted augmenting effects on the antibody titres.
It is concluded that Ampisol 20% had no immunosuppressive effects rather it exerted favourable effects on the weights of immunoregulatory organs, rpp albumin, globulin, A/G ratio, DLC and HI antibody titres against Newcastle disease virus. Esb3 30% moderately depressed the aforesaid components of immune system. The present study also revealed that vitamins (A, D3, E, K3) supplementation to anticoccidials improved the immune response of birds. However, there is a need for further investigation in this regard, with special reference to immune system of broiler chickens.

Publisher: 1998Dissertation note: The main objective of the present study work was to investigate the prevalence of various diseases and economic losses resulting because of various factors among the commercial layer farming in Tehsil Arif Wala. The farms having housed birds 5000 - 15000 were visited in this study work. The project was divided into two portions. The data of retrospective study revealed total mortality of 16.44% ( 58725/357100 ) due to various diseases. Highest mortality was due to gumboro (27.50%) followed bt leukosis (26.38%), Newcastle disease (15.33% observed only in one farm) early chick mortality ( 5.06%), heat stress ( 4. 14 %), coryza (3.09%) and Salmonellosis ( 1.98% ). The diseases in which the mortality was less than 2% were E-coli, Coccidiosis, C.R.D., I.B., Aspergillosis, Enteritis and Pox.
In active surveillance mortality was 27.28% (52019/190700) clue to various diseases. Highest mortality was due to Icukosis (24.57%) followed by Marek's disease (12.98%), early chick mortality (12.75%), gumboro (10.54%), C.R.D. (7.39%), Aspergillosis (7.10%), E-Coli (6.75 %), Coayza (4.81%), saimonellosis (4.33%) and enteritis
(3.86%). The diseases in which the mortality was less than 3% were
Coccidiosis, l.B., and Heat Stress.
In retrospective study economic losses by different factors were chicks ( 25.61%), feed (67.31%) and medicine (7.08%). In active surveillance economic losses due to different factors were chicks (32.29%), feed (62.53%) and medicine (5.18%).
From this study it is concluded that viral infections such as gumboro, leukosis, Marek's and N.D. are important in layers responsible for high mortality and economic losses. Therefore, it is recommended that proper vaccination should be done and propel vaccination schedule should be adopted
The diagnosis of each disease was made by clinical findings and postmortem findings but in case of active surveillance, the diagnosis of Salmonelosis was confirmed by the laboratory tests. A questionnaire was also designed to collect the data from each farm that was related to morbidity rates, mortali rates , vaccination, susceptible age , managemental faults & economic losses for various diseases.

Publisher: 1998Dissertation note: This study was designed to find out the effects on haematology (Hb, TLC and DLC), immune response (against NDV vaccine) and on organ body weight indices (liver, spleen, bursa of Fabricius and thymus) in broiler chickens when given two different HPS vaccines (Formalinized and oil-based HPS vaccines). Morbid livers of chickens affected with naturally occurred hydropericardium syndrome (HPS) were collected from field outbreaks to prepare the HPS vaccines and inoculum. Sixty broiler chicks were divided into three groups (A, B and C), comprising of 20 chicks in each on 10th day of experiment. At 14th day of age, chickens of groups A and B were given f-HPS and o-HPS vaccines, while group C was kept as unvaccinated control. On 28th day of age chickens of groups A, B and C were challenged with HPS inoculum. To study the effects of f-HPS and o-HPS vaccines, blood samples were collected on 12th (pre-vaccination), 26th (postvaccination) and 35th (post-challenge) day of experiment.
Haematological study revealed that f-HPS and o-HPS vaccines had no significant effects on haemoglobin concentration in groups A and B, but its concentration decreased significantly on 35th day in control group-C. Whereas TLC values increased significantly on 26th and 35th day in groups A and B, but decreased significantly on 35th day in group-C. DLC value revealed that there was relative lymphocytosis and heterpenia on 26th and 35th day in groups A and B, whereas eosinophilia on 35th day. While in control group-C there was lymphopenia and eosinopenia along with hetrophHia on 35th day. Antibody titre against Newcastle disease virus vaccine indicated that there was no significant difference in'GMHI titre values among the groups A, B and C. Results of organ body weight indices indicated that in control group-C (unvaccinated) indices of liver, spleen and bursa of Fabricius were significantly higher than those of groups A and B, whereas no effect was observed on thymic body weight index among groups A, B and C.
The results of this study suggested that f-HPS and o-HPS vaccines had no significant effect on Hb concentration, TLC and DLC values. No significant immuno-modulatory effect was noted on antibody titre against NDV vaccine of these HPS vaccines, whereas significant effect was noted on organ body weight indices of livers, spleen and bursa of Fabricius in group-C as compared to vaccinated groups.

Effect Of Replacement Of Maize With The Varying Levels Of Stabilized Extruded Rice Polishing On The Performance Of Broilers
by Aqif Mukhtar, Syed | Prof.Dr. Nisar Ahmad Mian | Dr.Anjum Khalique | Dr.Muhammad.
Material type: ; Format:

Publisher: 1998Dissertation note: As the poultry industry flourished rapidly during the last thirty years, it has now become a major contributor in providing low cost protein of animal origin to our population. But unfortunately poultry industry is continuously suffering loses for the past few years mainly due the fact that the conventional feed stuffs are becoming costly day by day. The serious food shortage and increasing competition between human beings and poultry regarding the consumption of cereal grains demanded that cereals should be now spared for human consumption and exploration of non conventional feed sources should be carried out in order to keep the business of poultry industry running well.
Rice polishing is a by-product of rice milling so it is abundantly available in Pakistan because rice is the third largest crop produced in the country. Rice polishing compares well with the cereal grains in chemical composition. So it contains more fat and protein as compared to maize but high in fiber contents. Due to high fat contents rancidity of Rice polishing can pose some problems if it is fed after prolonged storage, specially in hot weather.
Extrusion cooking is a new technique which stabilizes the high fat diets and make them fit for use in the animal rations. For this reason full fat rice polishing was subjected to Extrusion Cooking which was done at National Feed Mill.
Present Experiment was conducted to replace maize with extruded rice polishing and to see the effects on the performance of broiler chicks. Six starter and six finisher rations were prepared and designated as A, B, C, D, E and F . All rations were isocaloric and isonitrogenous. Starter ration and finisher ration A. were kept as a control containing 35 % Maize and 0% extruded Rice polishing, which was replaced by extruded rice polishing in ration B, C, D, E and F. on protein equivalent basis at 15, 20, 25, 30 and 35% level In this way a complete 100% replacement of maize with extruded Rice polishing was made One hundred and eighty day old chicks were randomly divided into eighteen experimental units of 10 chicks each. Each experimental unit was placed individually. The starter rations were fed up to 28th day of age while the Finisher rations from 29th to 42nd day of age.
Results of the present study indicated that the weight gain up to 25% extruded rice polishing level was promisingly good. Maximum weight gain was recorded in Ration B (15% extruded rice polishing). Second best results were noted in the control ration but the performance of the chicks fed on 20% extruded rice polishing was almost equal to that of control ration. It was noted that the weight gain started to decrease gradually as the level was raised up to 35% of the total with each increasing increment.
Best feed utilization was observed in the chicks fed on ration B, whereas poor utilization of feed was noted in higher levels of extruded rice polishing in the diet having more feed consumption compared to weight gain.
Better performance up to 25% level indicated that Extrusion improved the nutritional quality of rice polishing by stabilizing it and inactivating Lipases. The extrusion also made starch more available for the birds and reduced the anti-nutritional elements of rice polishing. This is evident from the fact that the level of rice polishing effected the health of the chicks.
It was therefore concluded from the present study that extrusion is an excellent technique for converting low quality feed stuffs into feeds with higher nutritional quality. Specially extrusion of low priced feed ingredients such as rice polishing and it replacement with a costly feed ingredient such as wheat or maize holds good economic prospects for feed millers. As extrusion is done on a very limited scale therefore after the present study it was strongly recommended that the use of extruded feed stuffs should be promoted in poultry ration

; Nature of contents: ; Literary form: Publisher: 1998Dissertation note: In the present study, a total of twenty Nili-Ravi buffaloes were divided into two equal groups. In group A ten buffaloes were administered with prostagladin F2 alpha (Lutalyse, Upjohn), 2 hours after calving. In group B, ten buffaloes were not given any treatment and designated as control. The reproductive organs of each experimental buffalo were rectally palpated on day 14 and day 21 postpartum. After that twice a week rectal palpation was carried out until the first postpartum oestrus.
The results of present study revealed that cervical and uterine involution was completed significantly (P < 0.05) earlier in group A as compared to group B (28.90± 1.79 and 35.40±3.95 days). There was no significant difference in the diameter of cervix, gravid and nongravid uterine horn at day 14 postpartum. A significant difference between the groups was obtained on days 21, 25 and 28 postpartum in the diameter of cervix and gravid horn. The corpus luteum (CL) of pregnancy regressed very rapidly following calving. The overall period required for complete regression of corpus luteum of pregnancy was (19.20±4.87 days) in treated group and (18.40±6.07 days) in control groups. The difference was significant.
Follicular activity resumed independently of uterine involution. It was, however, delayed slightly by the retained corpus luteum of pregnancy. The mean postpartum interval of initial follicular development was 21.20±5.71 days in treated and 28.20±8.75 days in control groups, respectively. The difference was statistically significant (P <0.05).
Postpartum oestrus interval was shortened in treated group (79.50±19.83 days) as compared to control group (103.0± 17.45 days) and the difference was significant (P<0.05). So it seems beneficial to administer prostaglandin F2 alpha in postpartum buffaloes to reduce the period for uterine involution and enhance the subsequent reproductive performance.

Publisher: 1998Dissertation note: The present study was conducted to evaluate the efficiency of sesame meal on the performance of Japanese quails. rfhe performance of the birds was studied by using different level of sesame meal in combination soyabean meal in the rations. The growth rate, feed intake, feed efficiency, dressing percentage and mortality was determined. One hundred and eight (180) one day-old Japanese quails were purchased from local hatchery. Quails were randomly divided into six groups and each group having three replicates. Six isocaloric and isonitrogenous rations were prepared in which sesame meal was replaced with soyabean meal fit, 0, 5, 10, 15, 20 and 25% of feed. Weekly feed intake, body weight gain and mortality were recorded. At the end o[' experiment three birds from each replicate were slaughtered to determine the dressing percentage. The data collected was analyzed by applying analysis of variance technique using least significant difference (LSD) test to detect the difference among the treatments and means, were compared by using least significant difference test.
The results showed that the ration D containing 10% soyabean meal and 15% sesame meal was best in promoting weight gain and feed efficiency. The results also revealed non significant difference in terms of feed consumption and dressing percentage.
It was concluded that the ration containing efficient proportion of both the vegetable protein supplements (15% sesame meal and 10% soyabean meal) was better as compared to any other ration combination. This was due to supplementary effect of both the vegetable proteins to each other.
Based on the results of present study it may be recommended that sesame meal could be incorporated in quails ration upto a level of 15% with 10% soyabean meal but the lysine supplementation should be made as per recommended level.

Publisher: 1999Dissertation note: The incidence of repeat breeding is high in cross-bred cows due to low LH level in the blood at the time of estrous. In this study Dalmarelin a GnRH analogue which induces ovulation in cows was used. Nine healthy animals with the history of repeat breeding and clinically normal genital tract were selected at the Livestock Production and Research Institute, Qadirabad, Okara. These animals were injected with dalmarelin (Lecirelin), at the dose rate of 2 ml IM. The injection was given on the zero day of estrous and later animals were inseminated artificially. Two blood samples were collected from these animals, one before the injection and artificial insemination i.e. on the zero day of estrous and the second at 10th day after the injection of Lacirelin for the detection of plasma progesterone concentration. Results indicated that five animals i.e. 55.5% had conceived. Similarly when detected 12 hours after the end of estrous five animals had ovulated out of which three animals were conceived. Finally, these animals were palpated rectally on the 90th day after artificial insemination and five animals with high concentration of progesterone on the 10th day, were, detected positive for pregnancy. None of the control animals ovulated and conceived.

Comparative Nutritional Evaluation Of Poultry By Product Meals Prepared By Two Separate Processes In Broilers
by Aftab Ahmad | Prof.Dr.Talat Naseer Pasha | Dr.Muhammad | Mr.Anjum Khalique.
Material type: ; Format:
print
Publisher: 2000Dissertation note: Protein as a second major factor in formulatiQn of poultry rations after energy. It is supplied by animal and vegetable sources. Animal protein supplement are superior in quality due to its more balanced amino acid profile but are costly. While vegetable proteins are cheaper but lacking in some amino acid and have some antiS nutritional factor. The animal protein supplements available in Pakistan are blood, fish, meat and PBPM. PBPM is abundantly available in Pakistan and it is prepared by using chicken feet, heads, viscera, feather skin and blood. And processing varies from organization to organization. PBPM is prepared by different organization such as M. Artal, BeBeJan and Kakasian.
PBPM has low cost and its CP and ME are comparable to fish meal, but it is low in lysine and methionine. Our present study was to compare the effect of processing of PBPM manufactured by BeBeJan and Kakasian feed industry. Both have different composition and different processing method of PBPM as blood was included in BeBeJan PBPM but it was absent in Kakasian.
The objective of study was to evaluate nutritional profile and quality of commercially available PBPM, the effect of processing on performance of broiler chicks. 240 day old Hubbard chicks were purchased from the local marked and were divided into 8 groups from A to H which were again subdivided into 3 replicates of 10 birds each. Eight experimental starter and 8 experimental finisher rations of A, B, C, 13 and E, F, G, H were prepared. A and E were the control group while B, C and D having 3, 6, 9% PBPM of BeBeJan and F, G, H having 3, 6, 9% PBPM of Kakasian were formulated and starter rations were fed to chicks upto 28 days of age while finisher was provided from 29 to 42 day of age. The feed was supplied to the chicks reared in cages at College of Veterinary Sciences, Lahore. The proximate analysis of the rations was done. And the parameters studied were weekly weight gain, feed consumption, FCR. At the end of the experiment three birds from each group were slaughtered to observe the dressing percentage and weight of internal organs. The economics of the experiment was also calculated. The pepsin digestability of both the organizations PBPM was also recorded. The data thus collected was subjected to statistical analysis. The results indicated that in BeBeJan group there was a significant weight gain in control group A (O%PBPM) while in Kakasian it was significant in F group having 3% PBPM. While comparing both organization PBPM it was observed that F&H rations having Kakasian PBPM 3% and 9% were better than B and D ration having BeBeJan PBPM 3 and 9% regarding weight gain while FOR of BeBeJan it was better in control group A (0% PBPM) while in Kakasian it was better in F group having 3% PBPM. While comparing both organations it was observed that Kakasian PBPM showed better FCR than that of BeBeJan. And it might be due to processing and no adultration of blood in PBPM by Kakasian, while BeBeJan PBPM contained blood. The dressing percentage of control group was better than treated group while comapring both organizations PBPM was non-significant difference among the groups.

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.

Publisher: 2001Dissertation note: The study was conducted to estimate the immune response of the three anticoccidial virus vaccines on NDV vaccinated broiler chicks. The vaccines used were, Eirneria tenella vaccine (ETV), Immucox and Coccivac. For this purpose a total of one hundred and five chicks were randomly divided into five groups, namely group A, B, C, D and E on day I Each group consisting of twenty one birds. All the chicks except those in group A, were occulonasally vaccinated with Newcastle disease virus vaccine using Mukteswar strain of virus on day I and 2 1
Chicks in group A were kept as non-i nfectecl, non-vaccinated controls. Group B was non-infected, hut vaccinated with NDV. group C was also vaccinated with Eimeria tenella vaccine on days 3 and 10 of age. Group D was administered with single dose of Immucox on day 5th of age and, group E was administered with Coccivac on day 6111.
After vaccination weekly mean weightgains, mean oocysts per gms of faeces (OPG), and mean feed conversion ratio of chicks in all the groups were recorded. Regular sera samples were also collected from the blood obtained from birds of all the groups, after administration of second dose of NDV on day 21 of age. All the sera samples were analyzed by using Haernagglutination (HA) and Haemagglutination inhibition (HI) tests.
obtained from birds of all the groups, after administration of second dose of NDV on day 21 of age. All the sea samples were analyzed by using Haemagglutination (HA) and Haemagglutination inhibition (HI) tests.
It was observed that no coccidiosis could be established in chicks of groups A, B and C. However oocysts were observed in the faecal material of chicks of group D and E after one week of administration of anticoccidial vaccines (immucox and coccivac) respectively. But OPG was gradually increase after second week of vaccination and one bird in group D died due to coccidiosis, OPG count reached to a peak after second week of vaccination and one bird in group D and one in group F died due to coccidiosis.
Mean weight gains per chick on day 1 was 41, 42, 40, 39 and 38 of groups A, B, C, D and F respectively. however the mean body weights were 1746, gms 1848, 1725, 1710 and 1695 gms for chicks in groups A, B, C, D and E respectively at Group B showed significant weight gain as compared to other groups and their difference of weight gain from group B was, 103, 123, 138, and 153 gms of groups A, C, D and F respectively. (P > 0.05).
Feed conversion ratio of groups A. B, C, D and F was 1.85, 1.99, 1 .88, 1.77 and 1.78 respectively at the end of experiment. Group B and C showed the best FCR as compared to other groups of the same age. But statistically the differences were non-signiFicant amongst all the test groups.
Morphometeric analysis of immuno modulatory organs revealed that group B showed highest organ weight and the organ body ratio as compared to other groups of same age at the end of experiment Besides group B, group C also showed the second highest of the organ body weights and the organ body ratios, as compared to other anticoccidial vaccinated groups D and E and among them group C showed the highest of organ weight and organ body ratio.
Antibody analysis revealed that geometric mean titre (GMT) in the chicks of group B (NDV vaccinated control group) showed the highest value (73.3) as compared to other groups of same age at the end of experiment. However group C showed the second highest value (68.6) on 49th day. Where as other anticoccidial vaccinated groups D and E showed their GMT value as 21.1 and 22.6 respectively, and antibody titre of group A (non-infected non vaccinated control group) was zero at the end of experiment.

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:
print
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%.
