The exponential increase in global population continues to present an ongoing challenge for livestock producers worldwide to consistently provide a safe, high-quality, and affordable source of protein for consumers. In the last 50 years, the poultry industry has spearheaded this effort thanks to focused genetic and genomic selection for feed-efficient, high-yielding broilers. However, such intense selection for productive traits, along with conventional industry farming practices, has also presented the industry with a myriad of serious issues that negatively impacted animal health, welfare, and productivity-such as woody breast and virulent diseases commonly associated with poultry farming. Bacterial chondronecrosis with osteomyelitis (BCO) lameness is one such issue, having rapidly become a key issue affecting the poultry industry with serious impacts on broiler welfare, meat quality, production, food safety, and economic losses since its discovery in 1972. This review focuses on hallmark clinical symptoms, diagnosis, etiology, and impact of BCO lameness on key issues facing the poultry industry.
全球人口呈指数级增长，这持续给世界各地的畜牧生产者带来挑战，要求他们持续为消费者提供安全、优质且价格合理的蛋白质来源。在过去50年里，家禽业通过对饲料高效、高产肉鸡进行重点遗传和基因组选择，引领了这一努力。然而，对生产性状的这种高强度选择，以及传统的行业养殖方式，也给该行业带来了一系列严重问题，对动物健康、福利和生产力产生了负面影响，比如木胸肉以及与家禽养殖常见的烈性疾病。伴有骨髓炎的细菌性软骨坏死（BCO）跛行就是这样一个问题，自1972年被发现以来，它迅速成为影响家禽业的一个关键问题，对肉鸡福利、肉质、生产、食品安全以及经济损失都产生了严重影响。本综述聚焦于BCO跛行的标志性临床症状、诊断、病因以及它对家禽业面临的关键问题的影响。
