The present study was conducted to record the incidence of chronic respiratory disease of layer and broiler birds in Ayodhya district of Eastern Uttar Pradesh. The naturally dead birds from 10 different private farms in Ayodhya district of Eastern Uttar Pradesh was collected for 6 months (October, 2018 to March, 2019). After post-mortem examination, the grossly suspected samples (trachea, air sac and lung) were kept for further histopathological and immunohistochemical study. These farms were visited during study period to screen the cases of chronic respiratory disease on the basis of clinical signs and symptoms like respiratory rales, open mouth breathing, ocular and nasal discharge, marked depression and weakness, decreased feed intake, feed conversion, egg production and hatchability. Out of total 16500 layer birds and 21600 broiler birds in ten farms selected for the present study, 2216 and 2346 cases of chronic respiratory disease were diagnosed in layer and broiler birds, respectively on the basis of history, clinical signs and gross pathological lesions in the dead birds. The incidence in layer was 13.42% whereas the incidence in broiler was 10.86%. The incidence rate was higher in the layers than broilers.
