The pancreas is a highly specialized multitasking organ, which plays a pivotal role in poultry production. The extent of pancreatic pathology in different poultry diseases of economic importance at different age groups and breeds particularly in Chabro and Vanaraja breeds of poultry has been studied to evaluate the lesions of pancreas in different pathological conditions and its correlation with various poultry diseases. An aggregate of 240 pancreases were gathered from chicken affected from different viral, bacterial, protozoal, fungal, metabolic, and toxicological diseases. The disease was confirmed by necropsy findings and further analysed by histochemistry with special staining. The major histopathological changes in pancreas in decreasing order of frequency were interstitial fibrosis, congestion, individualization of acinar cells, pancreatic fat necrosis in exocrine pancreas, periductular fibrosis and capsular thickening. However, no direct correlation was found between gross pathology and histopathological findings. It has been observed that pancreatic disorders were more common in metabolic and chronic diseases as compared to other infectious poultry diseases. Significant pancreatic pathology and their dysfunctions are an important contributory factor in chronic disease of known or idiopathic origin. Supplementation of pancreatic enzymes in poultry ration in case of disease outbreak/poor growth performance are suggestive for optimal functioning of pancreas and in turn assurance of healthy poultry flock.
