Abstract

Chronic respiratory disease is one of the important disease of poultry characterized by manifestation of respiratory signs, decreased egg production, reduced hatchability rates, altered reproductive efficiency of layers and downgrading of carcasses at slaughter. The patho-epidemiological investigation was carried out to know the incidence and mortality pattern in poultry affected with chronic respiratory disease in Gonda district of Uttar Pradesh. The naturally dead birds from eight private farms were collected from October, 2018 to March, 2019. The overall incidence was 12.64% with mortality of 9.10%. Grossly, trachea revealed congestion and haemorrhages with catarrhal exudates. Microscopically, trachea revealed thick layer of necrotic material in tracheal lumen with lymphocytic aggregation. Air sacs were covered with caseous exudates and microscopically showed necrotic material with lymphocytic infiltration. Macroscopically, lungs appeared dark red colour showing congestion and haemo
