  1. Values are means ± SEM, means in a row without common superscripts are significantly (P < 0.05) different. Level of significance = ns (not significant) = P > 0.05; *P < 0.05, glutathione peroxidase (GSH-Px); total antioxidant activity (T-AOC); malondialdehyde (MDA); superoxide dismutase (SOD); MSG levels in g/kg diet
