The hepatic redox parameters. A and B DHE Staining with frozen liver sections and fluorescence intensity of ROS; C–E Hepatic H₂O₂, O₂⁻ and T-AOC content; F–H Hepatic T-SOD, CAT and GPX activity; I Hepatic MDA content. W0, W1, W4, W7, and W14 respectively represented 21, 22, 25, 28, and 35 days of age. Data were presented as mean ± SEM (ROS, n = 3; others, n = 6). Values with different letters differ significantly (P < 0.05). ROS: Reactive oxygen species; T-AOC: Total antioxidant capacity; T-SOD: Total superoxide dismutase; CAT: Catalase; GPX: Glutathione peroxidase; MDA: Malonaldehyde
