A Comparative Study Of Gastro-Intestinal Helminths In Desi (Indjegenous) & Commercial Layers With Taxonomy Of The Isolates

by Saleem Khan, M | Dr. Asif Rabbani | Dr. M. Sarwar | Dr. Mubashar Saeed Mian | Faculty of Veterinary Sciences.

Material type: book Book; Format: print Publisher: 1991Dissertation note: The present project was designed to estimate and compare the extent of helminth infestation in Desi (indigenous) and commercial (W.L.H) poultry layers along with taxonomi study of the isolated species. A total number of six hundred (600) gut samples of adult layers i.e. three hundred (300) each of desi (indigenous) and commercial (W.L.H) were collected from June through october 1991. The parasites were recovered from the gastrointestinal tract of birds by adopting described method at the Parasitology Laboratory College of Veterinary Sciences Lahore. The overall prevalence of helminth parasites (netnatodes and cestodes) was 80.3% in desi and 32.6% in commercial (W.L.H) birds. The nematodes were found in 210(70%) in desi (indigenous) and in 62 (20.6%) of commercial (W.L.H) guts. Among the nematodes different species were identified and their infection rate on single and/or multiple basis was established. Ascaridia galli was the most prevailing species 167 (55.6%) followed by Heterakis allinae 38(12.6%), Subulura bruinpti 45 (1b.k) wniie iiojua trachea was very rare and was present only in 5 (1.6%) of desi (indigenous) birds. In commercial (W.L.H) layers the nematodes singly and/or on multiple basis were recorded in 98(32.61) of birds Ascaridia alli alone infected 49(16.3%), HtrJd. gallinae 7 (2.3%) and Subulura brunipti 8 (2.6%) of birds while Svnainus trachea was very rare and present only in 2 (0.6%) of the tracheas. The overall incidence of cestodes was slightly higher than those of nematode parasites. It was found to be 65.0% and 22.6% in desi (indigenous) and commercial (W.L.H) layers respectively. The species of cestode with percentage of infection recovered from the small intestine of desi (indigenous) birds were: Raillietina tetraona 58.0% (174/300) Raillietina cesticillus 12.6% (38/300) Raillietina echinobothrida 14.0% (42/300) Cotugnia digonoora 10.8% (32/300) Choanotaenia infundibulumn 20.0% (60/300) Amoebotaenia sphenoides 3.3% (10/300) While in conimercial (W.L.H) layers Raillietina tetraona Raillietina cesticillus Raillietina echinobothrida Cotunia dionopora Choanotaenia infundibuluni Anioebotaenia sphenoides they were: 22.0% (66/300) 1.0% (3/300) 3.0% (9/300) 1.0% (3/300) 4.3% (13/300) 2.0% (6/300) No trematode parasites was however recovered both in desi (indigenous) and commercial (W.L.H.) birds during the present study.

Taxonomical Study Of Treatment Infections And Their Effect On Blood Picture In Sheep And Goats

by Sulman Hameed | Dr. Asif Rabbani | Dr. Haji Ahmad Hashmi | Dr. M. Sarwar | Faculty of Veterinary Sciences.

Material type: book Book; Format: print ; Literary form: not fiction Publisher: 1996Dissertation note: In the present study two hundred sheep and two hundred goats both above one year of age and below one year age were examined after their slaughtering at abattoirs of Lahore for the presence of Gastrointestinal trernatodes during the month of May to August, 1995. Monthwise prevalence of p. Cervi, f... hepatica a6% D. dendriticum and D. dendriticurn during the month of May to august, 1995, was as under: May 1995 15% cervi, 20% f hepatica 6% D. dendriticum June // 19% P.cervi 27% f. hepatica 8% D. dendriticum July // 33% P.cervi 40% hepatica 16% D. dendriticum August // 28%P.cervi 32% f hepatica 13% D. dendriticurn It was observed that the infection increased gradually and reached at peak in the month of July and then declined. An overall incidence of 64.25% of trematodes was recorded in both the species. The parasitic incidence was as . cervi 23.75%, .J hepatica (29.75%) and .. dendriticum (1 0.75). So the rate of infection was on the peak in the month of July in P.cervi, E. hepatica and . dendriticurn as shown in Figure 1. The hernatological values of sheep and goats infected with trernatodes were :total Erythrocytic count 1 2.01 3 ± 0.096 million/cubic microliter, Haemoglobin level 8.037±0.160 g/l00rnl, Packed cell volume 30.10 ± 0.326%, IErythrocytic sedimentation rate 2.71 ± 0.242 mrn/24 hours and Total Erythrocytic count 10.973 ± 0.094 million/ microliter, Haemoglobin 7.637±0.128 g/1 OOml, Packed cell volume 28.15 ± 0.316% and Erythrocyte sedimentation rate 1.94±0.246 rnm/24 hour respectively for sheep and goats. It was observed that the infection with trernatode had an adverse effect on total erylhrocyte count, haemoglobin level and packed cell volume.

Study On The Prevalence Of Genus Trypanosoma And Effects Of Natural Infection On Various Blood Parameters In Dogs

by Afzal, M | Dr. Kamran Ashraf | Dr. Asif Rabbani | Dr. M. sarwar | Faculty of Veterinary Sciences.

Material type: book Book; Format: print ; Literary form: not fiction Publisher: 1998Dissertation note: The study was conducted to determine the prevalence of genus trypanosome and the effects of natural infection on some blood parameters in dogs. For this purpose blood samples of 500 pet dogs (250 adult dogs and 250 pups) were examined at Dog Hospital, College of Veterinary Sciences, Lahore. Giemsa staining procedure was admpted to stain glass slides having blood smears made from blood samples. Out of 500 ogs, 30 dog were found positive for tryponosomiasis. It revealed that only 6% prevalence of trypanosomiasis in dogs was estimated. In case of adult dogs out of 250 dogs, 13 dogs (5.2%) and in pups out of 250 dogs, 17 dog (6.2%) were found trypanosome infected. So pups were found more susceptible as compared to adult dogs. During research it was also noticed that mot of the dogs which were found positive being kept with horses. Then blood samples of 10 adult dogs and pups each which wre positive for trypanosomiasis and 10 adult dogs and pups each which were healty (as control) were further examined for the estimation of haemoglobin paced cell volum, erythrocytes sedimentation rate and total serum protein to check the effects of natural infection on mentioned blood parameters. The blood parameters of trypanosome infected and healthy adult dogs were compared and similarly blood parameters of trypanosome infected and healthy pups were compared. For this comparison unpaired 't' test was applied. By calculation it was found that haemoglobin, packed cell volume and total serum protein of trypanosome infected adult dogs and pups were significantly decreased as compared to healthy adult dogs and pups, respectively. But the erythrocytes sedimentation rate was found significlantly increased in case of trypanosome infected adult dogs and pups as compared to healty, adult dogs and pups.
