The selection for rapid growth from approximately 40 g to 3 kg in 42 days has inadvertently led to leg bone disorders, such as tibial dyschondroplasia (TD), rickets, and valgus-varus deformities, resulting in lameness, economic losses, and welfare issues in broilers. TD, a common metabolic leg bone disorder in broilers, disrupts the normal sequence of chondrocyte differentiation, where the normal conversion of cartilage to bone is interrupted. Nutrition plays a crucial role in bone growth by influencing bone structure, mineral bioavailability, ...
