Pathological studies of enteritis in chickens of Odisha

Abstract

The pathological study of enteritis in chicken was carried out in two organised farms of Odisha over a period of one and half years. Dead birds with history of diarrhoea, vent soiling, increased mortality was thoroughly necropsied. The changes in the entire length of intestine were studied in detail. The tissues were processed, sectioned and stained with routine Haematoxylin-Eosin stain for studying histopathological changes. The major clinical signs observed during the physical visit to the farms and recorded from the owner’s complaints were dullness, depression, drowsiness, watery to mucoid yellowish diarrhoea, and soiled vent. At necropsy, the carcasses were dry, dehydrated with atrophied muscles with a predominant involvement of anaemia and debility. In gross examination of intestine, there was yellowish catarrhal content and undigested food materials in the duodenum. The most common microscopic lesion in intestines were desquamation, presence of necrotic debris & inflammatory cells with congestion of the mucosa.
