¹W0 = TMR containing 0% wheat; W10= TMR containing 10% wheat; W20 = TMR containing 20% wheat; BP10 = TMR containing 20% wheat plus10% beet pulp; ²a–c Means with different superscripts in the same row differ (Tukey’s test; P<0.05); ³Blood samples were taken at 0 and 6 h post morning feeding; ⁴SEM = Standard error of the mean; ⁵Total antioxidative capacity; ⁶Malonaldehyde; ⁷Super oxygen dehydrogenises; ⁸Glutathione peroxidase.
