Values are presented as mean and pooled SEM, n = 6.

Data in the same row with no or the same letter indicate no significant difference (P > 0.05), while data with different letters indicate a significant difference (P < 0.05).

ITMs, inorganic trace minerals; OTMs, organic trace minerals; MDA, malondialdehyde; T-AOC, total antioxidant capacity; T-SOD, total superoxide dismutase; CuZn-SOD, copper-zinc superoxide dismutase; Mn-SOD, manganese superoxide dismutase; CAT, catalase; GSH-px, glutathione peroxidase; prot, protein.
