1CNTR = basal diet; PALM = diet containing 10% palm oil; POUF = diet containing 10% poultry fat; FISH = diet containing 10% fish oil; CORN = diet containing 10% corn oil; FLAX = diet containing 10% flaxseed oil.
2SOD = superoxide dismutase; GSH-PX = glutathione peroxidase; MDA = malonaldehyde; T-AOC = total antioxidant capacity; CAT = catalase; GSSH/T-GSH = the ratio of oxidized glutathione (GSSH) to total glutathione (T-GSH).
