Postmortem findings in collared peccaries raised in captivity in northeastern Brazil

Abstract

This study is a retrospective examination of diseases in collared peccaries that were diagnosed by the Veterinary Pathology Laboratory, Universidade Federal Rural do Semiárido. Necropsy and histological examination were performed from 2005 to 2010. Of the 50 necropsied collared peccaries, 24% died due to restraint and capture myopathy; 18% died from trauma; and the remainder was diagnosed with splenic hemangioma (6%), enterolithiasis (6%), gastritis (6%), gastric ulcer (4%), intestinal volvulus (4%), gastric volvulus (2%), mammary carcinoma (2%), polycystic kidney disease (2%), pyometra (2%), and suppurative bronchopneumonia (2%). Twelve animals remained undiagnosed, seven of which (14%) were in advanced autolytic condition and five of which (10%) had no gross or microscopic lesions that were compatible with disease. This paper describes illnesses that have not been reported in the collared peccary, focusing on their clinical and pathological aspects.
