Hypoxia-mediated programmed cell death is involved in the formation of wooden breast in broilers

Background Wooden breast (WB) myopathy is a common myopathy found in commercial broiler chickens world- wide. Histological examination has revealed that WB myopathy is accompanied by damage to the pectoralis major (PM) muscle. However, the underlying mechanisms responsible for the formation of WB in broilers have not been fully elucidated. This study aimed to investigate the potential role of hypoxia-mediated programmed cell death (PCD) in the formation of WB myopathy. Results Histological...
