A Comparative Study Of Lungworms In Sheep & Goats & The Effect Of Mixed Namatode Infection On Certain Blood Parameters

by Irshad Ahmed Sherazi | Dr. Sh,. Asif Rabbani | Dr. Muhammad | Dr. Muhammad Afzal | Faculty of Veterinary Sciences.

Material type: book Book; Format: print 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.

Taxonomical Studies Of Endo Parasites & Their Sequence Of Prevalence At Different Ages Of Layers

by Anwar ul Haq | Dr. Hajid Ahmad Hashmi | Dr. Mubasher Saeed Mian | Dr. Sh | Faculty of Veterinary Sciences.

Material type: book Book; Format: print Publisher: 1994Dissertation note: In the present study the total infection of gastro-intestinal parasites were studied in commercial layers, maintained at various poultry farms located in and around Lahore. About 930 faecal samples were collected from those birds which were dewormed at least one month before. Birds were divided into six age groups starting from Week-i to 48. Out of 930 faecal samples, 689 (74%) were positive for parasitic infection and 241 (26%) were negative. Ascariclia g.1ij was found in 432 (46.4%) faecal samples, Heterakis gallinarum 326 (35%) and Coccidiosis in 237 (25.4%) of the total faecal samples examined. The age wise incidence of parasites in group A (1-8 wks) was 59.3%, in group B (9-16 wks) 66.04%, iii group C (17-24 wks) 74.1%, in group D (25-32 wks) 74.8%, in group E (33-40 wks) 88.3% and in group F (41-48 wks) 81.2% i.e. ascending order of infection. In case of seasonal prevalence of infection, the occurrence of Nematodes in June was 41.25%, in July 40.25%, in August 45.75% and in September 38.80%. The incidence of Coccidiosis in June was 27.7%, in July 24.8%, in August 16.1% and in September 28.5%. The results were recorded on the basis of E.P.G. (Egg Per Gram) of nematodes and O.P.G. (Oocyst Per Gram) of Eimeria species. In general low body weight gain and low Egg production (30-40%) in the parasitised birds as compared with non-parasitised birds were noted. Statistical analysis revealed non-significant difference between prevalence of different species of parasites in the birds.

Epidemiolgical Surey Of Rabies By Applying Gel-Diffusion And Its Comparative Efficacy With Flourescent

by Zafar Ul Ahsan | Muhammad Ajmal | Dr. Sh. M. Amin | Dr. Tufail M. Khan | Faculty of Veterinary Sciences.

Material type: book Book; Format: print Publisher: 1990Dissertation note: An attempt was made to demonstrate rabies virus/ antigen in the saliva/ brain tissue of affected/ suspected/ healthy animals belonging to different species, using agar gel precipitation (AGPT), fluorescent antibody (FAT) and mice inoculation (MIT) to understand the epidemiology of the disease. A total of 201 dogs (100 stray and 101 suspected), 109 mongooses (102 routinely trapped normal healthy and seven suspected carcases) and eleven suspected domestic animals I six cattle, two buffaloes, two goats and a mule) were tested for the presences of rabies virus/ antigen in the saliva and/or brain tissue. Three diagnostic methods AGPT, FAT and MIT were applied to determine their efficacy. In case of 100 stray dogs, none was found positive. Out of 101 suspected dogs 54 (53.46%) were found positive for rabies. All the routinely trapped mongooses were found negative, where as all the 7 suspected mongooses were positive for rabies. Of the 11 domestic animals six cattle, one buffalo, two goats and a mule were found positive. Of the total 321 animals of different species 18(5.60%) were shown positive with AGPT, 69(21.49%) with FAT and 71(22.11%) with MIT. The FAT with combination of MIT was found the most sensitive, reliable and quick test for diagnosis. It was observed that healthy routinely trapped mongooses and healthy stray dogs do not act as carrier. But affected mongooses alongwith rabid dogs also play an important role in disseminating the rabies disease in the country.
