Seasonal Prevalence of Parasitic Helminths in Backyard Chicken in Kodad Region, Suryapet (Dt.), Telangana

The present study deals with the seasonal prevalence of helminth parasites in Gallus domesticus at different seasons. The present study was cncentrated only on the prevalence cestode (Rallientina) and nematode (Ascaridia). The survey was conducted during, the annual cycle June 2012 to May 2013 from different sampling station to estimate the seasonal prevalence of parasitic helminths. For this study the population size (n=320) in kodad, suryapet district observed as 265 chicken were infected. A simple salt floatation method was employed for examination of parasitic helminths. The overall prevalence found 265 (82.81 %) during the annual cycle. Which of these, nematode species of Ascaridia galli, and cestode species of Rallientina tetragona reported. The seasonal prevaence of parasitic helminths was highest during summer (93.26 %), followed by rainy (84.80 %) and lowest during winter (71.30 %). The average helminth parasites found in the domestic chicken were cestodes 86 (26.77 %), nematodes 123 (38.49 %) and mixed infection 56 (17.15 %). The percentage of seasonal prevalence of cestode (summer: 29.62Rainy: 26.60 % and winter: 24.09 %), nematode (summer: 41.16 %, rainy: 38.22 % and winter: 36.09 %) and mixed infection (summer: 20.36 %, Rainy: 17.18 % and winter: 14.85 %). The results are discussed in relation to ecological parameters of parasitic helminths whose prevalence is found highest during summerfollowed by rainy and lowest during winter.
