Normal development and growth of bones are critical for poultry. With the rapid growth experienced by broiler chickens, higher incidences of leg weakness and lameness are common problems in adolescent meat-type poultry that present huge economic and welfare issues. Leg disorders such as angular bone deformities and tibial dyschondroplasia have become common in broilers and are associated with poor growth, high mortality rates, increased carcass condemnation, and downgrading at slaughter. Probiotics have shown promise for a variety of health purposes, including preventing diarrhea, elevating carcass quality, and promoting growth of the poultry. In addition, recent studies have indicated that probiotics can maintain the homeostasis of the gut microbiota and improve the health of the gastrointestinal tract, which confers a potentially beneficial effect on bone health. This review mainly describes the occurrence of broiler leg disease and the role of probiotics in bone health through regulating the gut microbiota and improving intestinal function, thus providing a relevant theoretical basis for probiotics to hinder the development of skeletal disorders in broiler chickens.
骨骼的正常发育和生长对禽类至关重要。肉鸡生长迅速，腿部虚弱和跛行的发生率较高，这是青少年肉用型家禽的常见问题，给经济和福利带来了巨大的影响。骨骼畸形如角度骨畸形和胫骨软骨发育不良在肉鸡中很常见，与生长不良、高死亡率、胴体废弃率增加以及屠宰降级有关。益生菌在预防腹泻、提高胴体质量和促进家禽生长等多种健康方面表现出了良好的效果。此外，最近的研究表明，益生菌可以维持肠道微生物组的内稳态，改善胃肠道健康，这对骨骼健康可能有有益的影响。本综述主要描述了肉鸡腿部疾病的发生以及益生菌通过调节肠道微生物群和改善肠道功能对骨骼健康的作用，从而为益生菌抑制肉鸡骨骼发育障碍的发展提供了相关的理论依据。
