Effect of sodium butyrate on lipid peroxidation, total antioxidant capacity and antioxidant enzyme activity in the plasma of goats fed the HG compared with HG alone and LG . a MDA. b T-AOC. c Total SOD activity. d GPx activity. e Catalase activity. All enzyme activities and biomarkers were evaluated spectrophotometrically, and the results are expressed as the mean ± SEM. Data were analysed by mixed model in SAS (SAS version 9.2, SAS Institute Inc., USA) and are expressed as the mean ± S.E.M. **P < 0.01, * P < 0.05. HG = high grain; LG = low grain; MDA = malondialdehyde; T-AOC = total antioxidant capacity; TSOD = total superoxide dismutase; GPx = glutathione peroxidase; CAT = catalase
