Effects of H₂O₂-induced oxidative stress on the mRNA (A) and protein (B) levels of the NF-κB pathway in the thigh muscle of broilers. (A) 21 and 42 days post-hatch; (B) 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).
