A Study on the Seasonal Prevalence of Raillietina Tetragona in Domestic Chick (Gallus Domesticus) from Warangal Region of Andhra Pradesh.

The prevalence of Raillietina tetragona, a helminth parasite was examined in domestic chick for a period of two annual cycles to determine the effects of seasonal variation on intensity and incidence of infection. The results show that the infection was more during summer followed by rainy and winter seasons. The infection was single or in association with other helminth parasites like Raillietina echinobothrida, Raillietina cesticillus and Ascardia galli. The results are discussed in relation to seasonal variation. The results were analysed by student t-test (P<0.05).
