Oxidative stress levels of sows and piglets. A, D, and G T-AOC, total antioxidant capacity; L0, at farrowing; L21, at weaning. B, E, and H GSH, glutathione; C, F, and I MDA, malondialdehyde. CON, basal diet group; CS100/300/500, basal diet supplemented with 100, 300, or 500 mg/kg of cysteamine (CS); NBW indicate piglets with a normal birth weight (1.4–1.6 kg); Data are presented as mean ± SEM (n = 6–8). Linear (L) and quadratic (Q) effects of inclusion amounts of CS were contrasted. Different lowercase letters represent significant difference at P < 0.05
