245		2	_aA Comparative Study Of Gastro-Intestinal Helminths In Desi (Indjegenous) & Commercial Layers With Taxonomy Of The Isolates
260			_c1991
502			_aThe 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.
