The incidences of FAdV infection in commercial broiler birds were observed in the age group of day old to 42 days. The maximum incidence was noticed in the age group of 30 to 40 days (55%) followed by 20 to 30 days (20%), 40 to 50 days (12.5%), 0 to 10 days (10 %) and 10 to 20 days (2.5 %). The maximum mortality of 20 per cent was recorded in 30 to 40 days of age group. In case of broiler breeder mortality of 2.5 per cent was observed between 49 and 56 days and in commercial layer grower chicken, the age group affected was 42 to 91 days with mortality ranging from 0.3 to 7.7 per cent.EnglishVeterinary ScienceThesis
