Taxonomical Studies Of Endo Parasites & Their Sequence Of Prevalence At Different Ages Of Layers - 1994
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.
