Abstract: Effect of season in the occurrence of various infectious diseases in broiler chickens in Kamrup and Kamrup (Metro) districts of Assam were investigated. These investigations were based on post-mortem examination of birds collected from 100 different farms selected for study from across the districts during 2015-2016. To study the effects of season, year long duration was divided into four seasons as per meteorological department, Govt. of Assam. A total of 567 birds were examined from 100 different farms. The highest incidence of disease was recorded as Hydro-pericardium syndrome (16.75%) followed by Omphalitis (13.40%), Colibacillosis (11.11%), Chronic Respiratory Disease (10.93), Infectious Bursal Disease (10.58%), Bronchitis (9.88%), Necrotic Enteritis (6.35%), Bacillary White Diarrhoea (5.11%), Newcastle Disease (4.59%), Brooder Pneumonia (3.70%), Gangrenous Dermatitis (2.82%), Laryngotracheitis (2.12%), Coryza (1.59%) and Bumble foot (1.06%). The incidence of Omphalitis, Colibacillosis, Bacillary white diarrhoea and coryza were found round the year though the differences in the rate of prevalence existed. Approximately half of the HPS outbreaks were noted during Monsoon. More than half of the total Chronic Respiratory Disease (CRD) and Bronchitis cases were seen during winter. The Hydro-pericardium Syndrome (HPS) was highest during Monsoon and whereas the incidence of mortality due to Chronic Respiratory Disease (CRD) and bronchitis were highest during winter.
