Mean values within a row with different superscripts letters denote statistical significantly difference (P < 0.05, n = 12). Abbreviations: C, basal diet group; CAT, catalase; GSH, glutathione; H₂O₂, Hydrogen peroxide; MDA, malondialdehyde; N1, N2, and N3, basal diets supplemented with 0.1%, 0.2%, and 0.4% of naringin, respectively; T-AOC, total antioxidant capacity; T-SOD, total superoxide dismutase.
