Abstract: Raising poultry is one of the best ways for rural women to make money, especially for marginal and landless farmers. Numerous issues impede the production of poultry, with infectious diseases by parasites being the primary cause. This study was conducted to gather up-to date information on the prevalence of GI parasitic infection in hilly chickens. For this purpose, 100 chicken’s fecal samples were collected from the Naikhongchhari upazila of Bandarban district. After 100 samples were examined and the positive case was 19 (19%). This research found that free range chickens (26.23%) were more vulnerable to GI parasitic infection than semi-intensive chickens (7.69%). According to this study, the prevalence of Ascaridia galli infection in young chickens under 1 year was 33.33%, while it was 10% or less in chickens 2 or more years old. In chicken weighing 1.2 kg, Ascaridia galli, Heterakis gallinarum, and Coopera spp. were more common. The frequency was lower (10.00%) in chickens weighing 2 kilograms or more. Younger birds have a less developed immune system and are lighter overall, which accounts for this. Regularly dewormed chicken had a lower prevalence (12.66%) of GI parasites than non-dewormed chicken (39.39%). Again, when fenbendazol was used for deworming, the prevalence of GI parasites infection was lower (7.69%), and when levamisole was used, it was higher (18.86%). Therefore, levamisole was less successful than fenbendazol for deworming chickens. Additionally, this study demonstrated that regular feeder and waterer cleaning contributes to a decrease in the incidence of GI parasite infection.
