Abstract | Infectious bursal disease (IBD) is a severe, highly contagious immunosuppressive disease that has become impediment for poultry production. To know the seroprevalence of IBD, a total of 1162 blood samples such as 257, 431 and 474 during 2017, 2018 and 2019 respectively, were collected from suspected layers and analyzed through agar gel precipitation (AGP) test. Results revealed that the overall seroprevalence of IBD was 38.29% which was nonsignificantly different (p>0.05) in different seasons during 2017 (38.13%), 2018 (35.73%) and 2019 (40.71%) respectively. The seroprevalence of IBD was significantly reduced (p<0.05) in vaccinated birds (14.31%) than non-vaccinated birds (26.03%) and birds having treatment (23.12%) compared to untreated birds (31.53%); whereas the seroprevalence was found nonsignificantly different (p>0.05) with age, sex, and type of treatment. These results demonstrated that the seroprevalence of IBD is not different in different seasons during 2017, 2018 and 2019 but have significant association with vaccine and treatment used.
