The present study had been conducted to explore the effect of corticosterone (CORT) on the induction of lipid peroxidation in skeletal muscle. The experimental chickens were subjected to 1 single s.c. injection of CORT (4 mg/kg of BW). Blood samples were obtained at the beginning and end of a 3-h experimental period. Muscle samples were obtained from musculus pectoralis major and musculus biceps femoris (BF) before and immediately after slaughter, and at 24- and 48-h time points postmortem. The result showed that plasma level of TBA reacting substances (TBARS) was significantly increased, whereas the activity of superoxide dismutase was decreased after CORT injection. Plasma level of total antioxidant power, as reflected by the ferric reducing-antioxidant power, was increased by CORT administration. The preslaughter level of TBARS could be increased by CORT administration in pectoralis major. In contrast, although the preslaughter level of TBARS was not significantly changed by CORT administration in BF, the augmented TBARS level was detected at 48 h postmortem in BF of CORT chickens. During the period of storage, the concentrations of TBARS increased, whereas ferric reducing-antioxidant power level decreased over time regardless of treatment. In conclusion, the data suggest that elevated CORT due to preslaughter stress would affect the redox balance in skeletal muscle. The result suggested that the oxidative stability during storage of meat is associated with the alteration in muscle physiology induced by CORT administration.
