The occurrence and the frequency of hepatic changes in chickens, including broiler (BC), layer (LC) and backyard chickens (BYC) were investigated. The retrospective and prospective study (2006-2021) was conducted with a total of 300 cases of liver disorders. Industrial poultry (BC and LC) were frequently affected (88%) and noninfectious changes were the most diagnosed (69%). Considering etiology or conditions, the hepatic changes were classified as follows: degenerative changes (42%), bacterial (28%), metabolic (15%), toxic (8%), viral (3%), neoplastic (2%), protozoal diseases (1.5%) and circulatory disorders (0.5%). Regarding the type of bird, degenerative, toxic changes and viral hepatitis were more frequent in BC. Circulatory and metabolic disorders, as well as bacterial hepatitis, were more frequently diagnosed in LC. Neoplastic and protozoal hepatitis occurred more frequently in BYC. The macroscopic examination in association with histopathology enabled the diagnosis of the hepatic changes in 59% of the cases. Considering bacterial hepatitis in commercial poultry, the etiological diagnosis is highly important, in view of the risk for public health, despite the obvious importance due to the productivity losses and condemnation at processing.
