Publisher: 1995Dissertation note: This study indicated that live Mycoplasma gallisepticurn vaccine when administered to the chickens vaccinated with Newcastle vaccination had immunosuppressive effects.
Live Mycoplasma gallisepticum vaccine partially interfered with the development of serum antibodies against NDV in vaccinated chickens. However, when live MG vaccine is done alone in the chickens it gives good serum antibody titres. rube injection to baby chicks on first 4 consecutive post hatching days with cyclophosphaniide resulted in lower body weights, poor FCR, destruction of the bursa of fabricius, poor antibody response of birds to vaccinations against MG and ND.
The weight gain and FCR studies. indicated that the birds which were vaccinated either against live MG or NDV had significantly higher body weights and FCR values than those vaccinated both against MG and NDV.
These studies further indicate that the birds vaccinated against live MG and ND had significantly lower serum antibody titres on day 48 than the birds which were vaccinated against either live MG or NDV.
From the results of this study it was concluded that F-strain MG vaccination effective the growth performance and feed conversion efficacy of broiler chicks. The live MG vaccination also interfered in the development of immune response (antibody titers) against Newcastle disease virus.

; Nature of contents: ; Literary form: Publisher: 1994Dissertation note: A total of 500 animals (sheep 250, goat 250), of both sexes and different age groups were examined for harbouring Pasteurella multocida in their respiratory tracts. The samples from live animals were collected by sterile cotton swabs, gently passed in their nasal cavity. The slaughtered animal's laryngotracheal region were directly approached for collection of samples. Lungs showing pathological lesions were collected from fifty animals each of both species. Tryptic soya broth was used for primary isolation of organism.
Only one goat yielded Pasteurella multocida which proved highly virulent both for rabbits and mice. The isolate fermented glucose, fructose, mannose, mannitol, sorbitol and saccharose producing acid only. A negative reaction was observed for arabinose, dulcitol, maltose, lactose, raffinose and salacin. The organism was positive for catalase, oxidase, indole production, nitrate reduction and hydrogen sulphide production tests. It gave a negative reaction for methyl red, voges proskauer, urease activity and gelatin liquefaction tests. The organism was found non-motile in hanging drop preparation.
The organism was highly sensitive to ampiclox, cefazolin and velosef, moderately sensitive to cephalexin, slightly sensitive to tobramycin, cloxacillin and resistant to lincocin, erythrocin, amoxydillin, doxycillin and sulpha-methaxazol trimethoprim.
Amongst the various disinfectants tested, the organism showed maximum susceptibility to sanitizer and poulphene, moderate sensitivity to saniguard and sanitec and resistance to phenyl, sanitol and phenol.
The organism in infected faecal matter maintained its viability for 9 days in shady place, sunlight and at room temperature. At a controlled temperature of 32°C. with 75-80% humidity, the organism remained alive for 10 days.

by Rakhshanda Perveen Cheema | Dr. Muhammad Akram Muneer | Dr. Haji Ahmad | Dr. Muhammad Naeem | Faculty of Veterinary Sciences.
Material type: ; Format:
print
Publisher: 1994Dissertation note: The birds that received arnprolium at recommended dosage levels had higher mean body weight than the chioramphenicol medicated, cyclophosphamide treated or untreated control birds.
Arnprolium treatment did not adversely affect the weight of bursa of Fabricius, spleen, thymus and liver of birds. Chioramphenicol treatment slightly depressed the weight of bursa of Fabricius and thymus. Cyclophosphamide treatment of birds in early life resulted in bursal atrophy and slight depression of splenic weight.
As compared to Cyclophosphamide treated and non-rnedicated control birds, the sera of NDV vaccinated birds fed Amprolium had higher antibody titres on day 42. The sera of chioramphenicol treated NDV vaccinated birds had lower antibody titres as compared to non-medicated control birds on day 42. The post-challenge sera of NDV vaccinated birds fed Amprolium also had higher antibody titre as compared to NDV vaccinated cyclophosphamide and chioramphenicol treated birds. The NDV vaccinated chioramphenicol treated and NDV vaccinated cyclophosphamide treated had high post NDV challenge mortality and the NDV vaccinated birds on amproliurn medicated rations and those on non-medicated rations did not have any significant post NDV challenge mortality.

Publisher: 1995Dissertation note: A total of 1318 blood samples and 290 egg samples were analyzed for the presence of antibodies to various strains of avian infectious bronchitis virus (AIBV). For this purpose broiler breeder, commercial layer, and layer breeder farms located in various geographical regions of the provinces of the Punjab and North West Frontier Province (NWFP) were visited, and flock histories in terms of production performances, growth patterns arid IB disease prevalence, were recorded) Attempts were made to sample only those farms which had experienced high morbidity, low production and mortality in the past growing or laying flocks housed at such farms. Samples from acute phase of illness and convalescent period were collected where ever possible. It was observed that there was a general trend to house and rear multiple age groups at the same time, the poultry farms were located at a very close distances from each other and were either not following any proper vaccination programmes or were not using any IBV vaccines. The seroprevalence of 1BV antibodies in unvaccinated flocks was more in areas where poultry farms were located in clusters or had developed into poultry estates In case of commercial layers, layer breeder and broiler breeder birds their misshapen and normal eggs were also collected for detection of antibodies to various strains/types of IBV. The serum and egg-yolk samples were analyzed using haernagglutination and haemagglutination-inhibition tests.This study indicated the presence of antibodies to various AIBV types such as Massachusettes-41 (M41), D-274 and D-1466. It was further observed that the breeder and commercial flocks which did not receive any killed or live IBV vaccination had significant levels of humoral and yolk antibodies indicating that various types of IBV were circulating in the poultry flocks in various areas of the Punjab and NWFP. The flocks indicating low egg production and quality; respiratory distress, and poor feed conversion ratios did suffer from the attack of some IBV strain(s) as they also had quite significant levels of humoral/yolk IBV antibodies)

Publisher: 1996Dissertation note: This project was designed to study the role of maternally derived antibody in protection against IBD and efficacy of immunization with live and killed IBDV vaccines. A total of 250 day old chicks were divided into five groups i.e. groups A, B, C, D and E, each group having equal number of chicks. Group A was non-treated control for the study of the decay rate of maternal antibodies. The chickens of groups, B, C and D were vaccinated with live, killed and combination of live and killed IBDV vaccines. All the chicks were vaccinated with NDV vaccines except group E which was kept as negative control. There was no interference in the IBDV and NDV in the development of immunity.
The birds showed the presence of passive immunity, both through AGPT and IHA tests. Maternal antibody was detectable only through AGPT. The IHA indicated the presence of immunity in all the birds upto day 14th.
It was further observed that the birds having maternal Ab titres against IBDV (upto a titre of 5.27) also resisted the experimental challenged with the CVS-6).
All the vaccinated groups indicated the immune responses post vaccination. Both the AGP and IHA tests detected decline in immunity on 7th day post-vaccination and then a gradual increase in titres at 14th day. The titres were at the peak after day 28 post booster vaccination.
The results of challenge indicated that the birds having antibody titre (GMT=68.39) against IBDV resisted the IBDV challenge. Typical clinical signs of IBD were noted. The bursa was odematous and double in size. The spleen and thymus were slightly enlarged. Statistical analysis of lymphoid organ body weight ratio's of spleen, bursa and thymus indicated a significant differences in the vaccinated and control chickens.

Publisher: 1998Dissertation note: The present project was aimed at knowing the ability of Mycoad in countering the ill effects on the health of broiler chicken, offered feed possessing acceptable levels of aflatoxins. The study was conducted on 140 birds, divided into two groups designated as A and B each given further sub-division into Al and A2, B1 and B2, all comprising equal number of birds. Groups Al and B1 were given plain feed and groups A2 and B2 were given medicated feed. The aflatoxin level of each feed sample was estimated prior to their use. The feed fed to group A birds had its aflatoxin level as 41.0 PPb, whereas the feed given to group II birds had 37.6 PPb of aflatoxin. The ill effects on the birds were determined on the basis of feed conversion ratio (FCR) values and immune response against ND virus.
The immune response of the birds given plain feed was poorer as compared to those winch were given Myco-ad treated feed. The GMT values of specific antibodies of the group Al birds came to be 36.8, 22.6, 8.6 respectively on 14th, 28th and 42nd day of the age of
birds, whereas group A2 birds had these values as 39.54, 29.69 and
11.64. The same was true for group B birds, where 111 birds gave
GMT values of 37.28, 26.64 and 41.92, respectively on 14th, 28th and
42nd day of the age of birds and B2 birds gave their values as 39.54,
29.69 and 11.64.
The FCR values based findings were also in support of birds given Myco-ad treated feed. The group Al birds gave their values as
1.26, 1.55, 1.77, 1.98, 242 and 2.32, respectively on 7th, 14th, 21st, 28th, 35th and 42nd day of the age of birds, whereas group A2 birds gave their values as 1.19, 1.50, 1.73, 1.96, 2.06 and 2.24. Similarly, group [11 birds showed FCR values of 1.29, 1.63, 1.73, 1.94, 2.08 and
2.40, respectively on 7th, 14th, 21st, 28th, 35th and 42nd day of their life, whereas group 132 birds gave their values as 1.17, 1.50, 1.68, 1.92, 2.03 and 2.24.
