a, bMeans followed by different lowercase letters on the same row differ by Tukey post hoc test (P < 0.05).
1Biochemical profile data are means of 10 pigs per treatment.
2GST: glutathione S-transferase, SOD: superoxide dismutase, and IgM: immunoglobulin M (8 pigs per treatment).
3(1) control diet containing isolated phytase and xylanase valued at 40 kcal of ME/kg (CD0), (2) CD0 + β-mannanase (0.3 g/kg valued at 30 kcal of ME/kg) (CD70), (3) CD0 + β-mannanase (0.3 g/kg valued at 45 kcal of ME/kg) (CD85), and (4) CD0 + β-mannanase (0.3 g/kg valued at 60 kcal of ME/kg) (CD100).
4SEM: pooled standard error of the mean.
