Abstract: The present study was conducted to investigate the status of infectious disease (IBD) in birds reared in fully intensive system for meat purpose. The study area was all five (05) upazillas (administrative unit of Bangladesh) of Dinajpur district within two months study period. 70 farms rearing 500 to 4000 birds were randomly selected from the study area. Birds were examined by clinical signs & post-mortem lesions to diagnose IBD. IBD positive cases were defined by any sort of lesions in Bursa of fabricius i.e: inflammation, haemorrhage, caseous necrosis or atrophy of the bursa. Among 70 farms 41 farms were infected with IBD. Maximum numbers of farms were infected between ages 03 to 05 weeks. Highest percentage of morbidity, mortality & prevalence were 15, 6.88 & 9.3 and lowest of those were 2.08, 0.47 & 3.09, whereas average percentage of morbidity & mortality were 5.58 & 2.07. The non-vaccinated birds were mostly affected with IBD(82.61%) than vaccinated group(46.81%).The risk factors were identified mainly wrong vaccination, overcrowding, poor ventilation heat stress and lack of bio-security. Proper vaccination was proved as the key to prevent the disease. Extensive studies are recommended for the serological and molecular study
