Abstract:
A study was undertaken to record the prevalence of gastro intestinal parasites of backyard poultry in Telangana state. The gastro intestinal parasites collected from the desi chicken slaughtered in poultry shops in selected districts of Telangana state were morphologically identified. Out of 480 gastro intestinal tracts examined, 432 harbored the parasites indicating 90% of prevalence in Telangana state. Mixed infection was identified in 408 samples (85%) and single infection in 24 samples (5%). The species identified were Ascaridia galli (70%), Capillaria obsignata (60%), Dispharynx spiralis (30%), Echinostoma revolutum (7.5%), Eimeria spp. (42.5%), Heterakis gallinarum (72.5%), Prosthogonimus spp. (5%), Raillietina spp. (75%), Subulura brumpti (27.5%) and Tetrameres spp. (52.5%). The present study was designed to study the zone, season, age and sex wise prevalence of gastro intestinal parasites in desi chicken. The zone wise prevalence of gastro intestinal parasites was higher in North zone (100%) followed by Central zone (88.23%) and South zone (77.78%). Age wise Prevalence studies of gastro intestinal parasites in Telangana state showed higher prevalence in chicks (100%) and growers (100%) than adults (80%). The incidence of parasites was higher in male birds (96.2%) than female birds (92.9%). Eimeria spp. and Tetrameres spp. were more prevalent in female and male birds, respectively. Season wise prevalence studies of gastro intestinal parasites in Telangana state showed higher prevalence during summer (95.83%) followed by rainy (100%) and least in winter (70%) seasons. Prosthogonimus spp. was the least prevalent parasite in all seasons. Dispharnyx spiralis, Echinostoma revolutum and Prosthogonimus spp. infections were prevalent only in summer season.
