CON = piglets fed the basal diet with intraperitoneal saline injection; LPS = piglets fed the basal diet and injected intraperitoneally with lipopolysaccharide (LPS) to induce stress; EO + OA + LPS = piglets fed the basal diet supplemented with essential oils (EO) and organic acids (OA) and injected intraperitoneally with LPS to induce stress; T-AOC = total antioxidant capacity; MDA = malondialdehyde; SOD = superoxide dismutase; GSH = reduced glutathione; GSH-Px = peroxisomal glutathione.
