Pathomorphological studies of pancreas in avian diseases

摘要

Pancreatic pathology was studied in 3796 poultry birds during post mortem examination in a year long study. Definite pancreatic pathology was recorded in 844 (22.23) birds. The major gross pathological findings in decreasing order of frequency were bleached appearance (36.97), congestion (36.97), mottled appearance with multifocal necrotic lesions (29.50), pancreatic deformity (15.17), atrophy (4.15), and hypertrophy (2.61). Prominent histopathological alterations recorded in decreasing order of frequency were interstitial fibrosis (54.41), congestion (46.57), dissociation and individualization of acinar cells (32.35), multifocal necrosis of exocrine pancreas (30.88), vacuolar degeneration with residual / apoptotic bodies (27.94), periductular fibrosis (13.24), zymogen overload (13.24) and capsular thickening (5.39). It was observed that occurrence of primary disease of pancreas was minimal in poultry; mostly the involvement was secondary in nature. However, the pathological changes clearly suggest that pancreatic abnormality is one of the major underlying causes for complication of disease process as well as its economic fallout in poultry.
