Git Helminthiasis Indigenous And Commercial Layers In District Quetta.Balouchistan - 2011
The study was conducted to identify and compare the extent of gastrointestinal helminths in indigenous poultry and commercial layers. For this purpose, 200 gut samples (100 each from indigenous and commercial layers) were collected from different sources of Quetta district. All the material was brought to disease investigation lab, Quetta, for detailed postmortem and coprological examination.
The overall incidence of nematodes in indigenous chickens and commercial layers was 87% and 08% respectively. Three species of nematodes were recovered from both indigenous chickens and commercial layers. Ascaridia galli was the most common specie of nematodes recovered from small intestine while Heterakis gallinae and Subulura brumpti were isolated from the caeca of the sampled birds. The incidence of Ascaridia galli, Heterakis gallinae and Subulura brumpti was 75%, 25% and 16% in indigenous chickens and 06%, 04% and 03% in commercial layers respectively.
The overall incidence of cestodes was lower than those of the nematodes. It was found to be 78% in indigenous chickens and 05% in commercial layers respectively.
Five species of cestodes recorded from the gastrointestinal tract of indigenous chicken and were Raillietina tetragona (60%), Raillietina echinobothrida (21%), Raillietina cesticillus (14%), Cotugnia digonopora (29%) and Choanotaenia infundibulum (13%). On the other hand, following two species of cestodes were isolated from the gastrointestinal tract of commercial layers and included Raillietina tetragona (04%), and Choanotaenia infundibulum (02%).
Older birds have higher prevalence as compared with younger birds in indigenous and commercial layers. Slightly higher infection rates were recorded in females (51.7%) as compared with males (48.2%). On coprological examination, a greater proportion of birds were found infected with various helminthes and infection rate in indigenous birds was 66% as compared with commercial layers which was 3%.
