Abstract

A cross-sectional study was conducted in 450 broiler farms of three districts of Bangladesh from June 2012 to July 2013. The estimated prevalence and mortality of infectious bursal disease (IBD) in three districts were 10.2% (CI, 9.2-11.2) and 7.8% (CI, 6.4-9.2) respectively. On clinical sign such as anorexia, ruffled feathers and diarrhoea and necropsy gross changes at bursa of fabricius, the highest prevalence was recorded in Comilla district (10.4%) followed by Feni district (10.3%) and Chittagong district (10.0%), while the highest mortality was recorded in the same Comilla district (8.3%) followed by Chittagong district (8.1%) and Feni district (7.0%). IBD was recorded year-round and had significant association (P<0.05) with season. Significantly higher prevalence (13.1%) and mortality (9.8%) was documented in winter season. Broiler chicken age between 21-30 days was significantly reported with high prevalence rate and high mortality rate. The study result indicated the difference of IBD occurrence in Bangladesh, thereby would support to improve the current control plans.
