Seasonal variation in prevalence and intensity of Raillietina spp. in Gallus gallus domesticus across the Kashmir valley

Abstract :

The present study was conducted from August 2017 to July 2019 to find the seasonal variation in prevalence and Intensity of Raillietina spp. in free-range backyard chicken (Gallus gallus domesticus) of Kashmir valley.  Of the total 549 chickens collected from different localities of Kashmir, 203 (44.3%) were found infected with three species of Raillietina. The prevalence rates of detected cestode parasites were; R. tetragona (40.63% & 39.16), R. cesticellus (31.96% &30.83%) and R. echinobothrida (23.28% &22.91%) for the years 2017-2018 & 2018-2019 respectively. The seasonal prevalence and mean intensity of the infection with the cestode parasites was studied and the highest rate was during summer followed by autumn, and spring while the lowest rate was during winter. Significant (p <0.01) relationship between the seasonality and prevalence of cestode parasites was observed. The current study was carried out to investigate changes in the incidence of cestode parasites of domestic fowl and their seasonal prevalence. Prevalence of these cestode parasites and severity of infection vary largely depending on environmental conditions and availability of intermediate hosts.
