Abstract

ABSTRACT: 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.

巴西家鸡肝脏的变化

摘要:研究了肉鸡(BC)、蛋鸡(LC)和后院鸡(BYC)肝脏病变的发生情况和频率。这项回顾性和前瞻性研究(2006-2021)共对300例肝脏疾病患者进行了研究。工业家禽(BC和LC)经常受到影响(88%)，非传染性变化被诊断最多(69%)。考虑到病因或条件，肝脏改变分为以下几类:退行性改变(42%)、细菌性改变(28%)、代谢性改变(15%)、毒性改变(8%)、病毒性改变(3%)、肿瘤性疾病(2%)、原虫病(1.5%)和循环系统疾病(0.5%)。就鸟类类型而言，BC中变性、毒性变化和病毒性肝炎更为常见。循环和代谢紊乱以及细菌性肝炎在LC中更常见。肿瘤性和原生动物性肝炎在BYC中更为常见。结合组织病理学的宏观检查使59%的病例能够诊断肝脏病变。考虑到商品家禽中的细菌性肝炎，鉴于对公共卫生的风险，病原学诊断是非常重要的，尽管由于生产力损失和加工过程中的谴责而显得非常重要。
