Dietary silybin supplementation alleviated the redox imbalance and growth retardation induced by paraquat challenges in piglets. (A) Schematic diagram of experimental design. (B) ADG on days 18–21. (C) ADFI on days 18–21. (D) F/G on days 18–21. (E–I) The activity of plasma CAT (E), SOD (F), GSH-Px (G), and the concentration of MDA (H) and H₂O₂ (I). Data are expressed as mean ± standard error. * p < 0.05. Ctrl = basal diet group treated with saline; Si = silybin diet group treated with saline; PQ = basal diet group treated with paraquat; Si + PQ = silybin diet group treated with paraquat; ns = not significant; ADG = average daily gain; ADFI = average daily feed intake; F/G = ADFI/ADG; CAT = catalase; SOD = superoxide dismutase; GSH-Px = glutathione peroxidase; MDA = malondialdehyde; and H₂O₂ = hydrogen peroxide.
