^a−cValues with different letters within the same row are significantly different (p < 0.05). CON, control; Se, dietary supplemented with 4.8 mg/kg selenium-yeast; An, dietary supplemented with 50 mg/kg purple corn anthocyanins; SeAn, dietary supplemented with 4.8 mg/kg selenium-yeast + 50 mg/kg purple corn anthocyanins. TAC, total antioxidant capacity; SOD, superoxide dismutase; GPX, glutathione peroxidase; CAT, catalase; MDA, malondialdehyde; O^2−., superoxide anion radical; IgA, immunoglobulin A; IgG, immunoglobulin G; IgM, immunoglobulin M.
