Data are expressed as mean ± standard error. Different lowercase letters in the same row indicate significant differences (P < 0.05). n = 6. CON, sows fed basal diet; XPC, sow fed basal diet + 2.0 g/kg XPC. CAT, catalase; GSH-Px, glutathione peroxidase; MDA, malondialdehyde; SOD, superoxide dismutase; T-AOC, total antioxidant capacity.
