ABSTRACT Five ailing and twelve carcasses of soviet chinchilla rabbit of both sexes were presented for clinical and post-mortem examination respectively from a private rabbitry with the history of continuous mortality. Detailed clinical and necropsy were conducted on ailing rabbits and dead carcasses. Heart blood and tracheal swabs were collected for microbiological studies. Organs showing lesions were collected in 10% formalin for histopathological studies. Feed sample was submitted to Animal Feed Analytical and Quality Assurance Laboratory for toxin analysis. Grossly, the liver was enlarged, hard in consistency and had yellowish white nodules on the hepatic parenchyma. Trachea showed severe congestion and haemorrhages. Culture examination of heart blood swab and tracheal swab revealed pasteurella multocida. Histopathologically, liver sections showed severe bile duct hyperplasia, periportal fibrosis, lumen of the bile duct contained varying developing stages of eimeriastediae. Trachea revealed loss of superficial epithelium and severe submucosal haemorrhage. Feed samples were positive for aflatoxins. The remaining rabbits in the rabbitry were recovered by suitable treatment with antibiotics, anticoccidial and liver tonics with change of feed.
