PATHOLOGICAL INVESTIGATION OF DISEASES IN BROILER AT DINAJPUR DISTRICT

Abstract

The prevalence of diseases in broiler encountered in commercial broiler farms at Dinajpur district of Bangladesh was pathologically investigated. The course of the study was one year from September, 2009 to August, 2010 under the Department of Pathology and Parasitology, Hajee Mohammad Danesh Science and Technology University, Dinajpur. The diagnosis of different disease conditions was done based on history, clinical signs, characteristic gross morbid lesions and histopathological study. In the present investigation, a total of 264 dead birds were collected for necropsy from different broiler farms. The highest proportional incidence of the diseases in broiler in the present investigation was recorded 25.75% which was due to Infectious bursal disease (IBD). This was followed by Newcastle disease (17.72%), Colibacillosis (14.01%), Coccidiosis (8.71%), MC complex (8.71%), Salmonellosis (7.57%), Aspergillosis (4.92%), Deficiency disorders (4.92%), Aflatoxicosis (4.54%) and Miscellaneous disease conditions (3.40%). The findings indicate that Infectious bursal disease (IBD) is the major disease problem in broiler farming at Dinajpur.
