Gross and histological examinations of spontaneous cholangiohepatitis in broiler chickens were performed. The specimens were collected from different batches - hybrids originating from 2 poultry farms in different regions of the country. Cholangiohepatitis-specific gross lesions were observed by the end of the finisher period or in carcasses at slaughterhouses. Liver histological lesions were detected at a different stage of development. The described results both gross - enlarged and hard livers with pale yellow colour, acinar surface, necroses and histopathological proliferative changes in bile ductules with secondary fibrosis, multiple liver granulomas, cholangitis and cholecystitis corresponded to signs described in broiler chickens with cholangiohepatitis.
