Effects of dietary supplementation with grape seed proanthocyanidin extract (GSPE) on small intestinal oxidative capacity of weaned rabbits challenged with hydrogen peroxide (H₂O₂). (A) MDA, malondialdehyde; (B) SOD, superoxide dismutase;(C) CAT, catalase; (D) GSH, glutathione. Control, rabbits fed the basal diet; H₂O₂, rabbits fed the basal diet and given intraperitoneal injection of H₂O₂; H₂O₂+GSPE, rabbits fed the basal diet supplemented with 400 mg/kg and given intraperitoneal injection of H₂O₂. ^a,b,c Means with different lowercase letters differ significantly among treatments (p < 0.05). n = 8.
