Abstract

Thirty sheep/lambs were brought for post mortem in Teaching Veterinary Clinical Complex, LUVAS and Central Sheep Breeding Farm, Hisar, which were investigated for gastrointestinal tract pathology in laboratory of Department of Veterinary Pathology. Mortality was maximum in sheep/lambs of age group 6 months to 1 year and higher in males than females. Gross pathological changes in gastro intestinal system noticed were congestion in abomasum, intestine, pancreas, liver and mesenteric lymph nodes. Histopathologically, there was congestion, desquamation of mucosal epithelium, submucosa in abomasum and small intestine including goblet cell hyperplasia. Congestion along with mild necrosis in pancreatic acini, liver parenchyma, peri portal area and mesenteric lymph node was observed along with haemorrhage in peri portal area and thrombosis of portal blood vessel in liver. Cloudy swelling, fatty changes, centrilobular necrosis in parenchyma and bile duct hyperplasia in liver was also reported.
