Effects of H₂O₂-induced oxidative stress on the mRNA and protein expression of the caspases in the thigh muscle of broilers. (A) Thigh muscle of broilers on 21 days post-hatch; (B, C) thigh muscle of broilers on 42 days post-hatch. Control is the noninjected treatment. Saline is 1 mL/kg BW physiological saline (0.75%) injected treatment. 2.5%H₂O₂, 5%H₂O₂, and 10%H₂O₂ are H₂O₂ treatments injected with 0.74, 1.48, and 2.96 mmol/kg BW H₂O₂ solution per bird. All data were represented as the mean value ± SE of eight sample birds per treatment; ^a,b,c means within a row with no common superscripts differ significantly (P <0.05).
