L-Citrulline supplementation modulates the anti-oxidant properties of broilers during acute heat stress. (A) Superoxide dismutase (SOD) activity. (B) Catalase (CAT) activity. (C) Malondialdehyde (MDA) content. (D) Glutathione peroxidase (GSH-Px) activity. (E) Total anti-oxidant capacity (T-AOC). Data are presented as mean ± SEM (n = 8). TNZ, thermoneutral; HS, heat stress. a,bDifferent letters indicate significant difference of D×E interaction at P < 0.05.
