Abstract: Ascariasis caused by Ascaridia galli is a common parasitic infection in chicken throughout the world.This infection is prevalent in all kind of production systems and cause substantial economic problem in terms of lower feed consumption, reduced weight gain, lower egg production and even death in case of heavy infections. Information about phenotypic variation is ultimate understanding the host parasite relationship as well as to design an effective control measures against this economically important parasite. Therefore, this study was conducted to get updated information on the prevalence of Ascaridia galli infection in chickens. For this purpose, a total of 200 chickens‘ feces was collected from hilly area (Rangamati, Khagrachari and Bandarban). 21 chickens out of 200 were found positive to the infection giving the prevalence as 10.5% of A. galli infection in chickens of the study area, of which males were 12 (57.14%) whereas females were 9(42.85%). The result of this observation indicates that there is a marked pattern of Ascaridia galli infection in both sexes. From this result without significant test it is difficult to prove it proved that males are more susceptible than females. Relatively young animals were more susceptible than adult. Age group wise prevalence was as follows 57.14 % in 14 -52 wks, 33.33 % in 1.5 -2 yrs and 9.52% in 2.5-3yrs respectively. It was documented that the rate of occurrence of A. galli in Summer 41.15%, Rainy 44.67% and winter 14.18%. Free range housing system chickens were more infected than semi intensives housing system. Anthelmintic were used more in semi intensives than free range housing system.
