Placental oxidative stress levels. The levels of total antioxidant capacity (T-AOC) (A, D), glutathione (GSH) (B, E), and malondialdehyde (MDA) (C, F) were normalized to the placental total protein. LBW and NBW indicate piglets with a low birth weight (LBW) (less than 1.0 kg) and normal birth weight (NBW) (1.4–1.6 kg), respectively. CON, basal diet group; CS100/300/500, basal diet supplemented with 100, 300, or 500 mg/kg of cysteamine (CS). Data are presented as mean ± SEM (n = 6). Linear (L) and quadratic (Q) effects of inclusion amounts of CS were contrasted. Different lowercase letters represent significant difference at P < 0.05
