Description The present study was conducted to investigate the pathology of oviduct in spontaneous cases of aflatoxicosis in commercial layer chicken. Among the 85 commercial layer feed samples analyzed for aflatoxin, 40 were found positive. Within the positive samples two
showed aflatoxin level of 100 and 260 ppb and the flocks received this ration exhibited the signs of clinical aflatoxicosis. In affected flocks, production drop, morbidity and mortality were 0 to 15, 0. 5 to 20 and 0.5 to 4.0 per cent respectively. Grossly, congested and degenerated ovaries with distorted and pedunculated ovarian follicles along with mature ones and no pathological changes in oviduct except congestion of serosal blood vessels were observed. Liver was enlarged, pale and friable in consistency. Histopathologically, oviduct showed focal to diffuse degeneration, necrosis of surface epithelium, infiltration of mononuclear cells and atrophy of tubular glands. Liver showed fatty change, individual cell necrosis, congestion, hemorrhage and bile duct hyperplasia. Presence of aflatoxin was detected only in liver (4 to 6ppb) of the birds which received 260 ppb aflatoxin in feed.
