a,b = means with different letters in the same column are significantly different at (p < 0.05). SEM, standard error of the mean. ≠ LSe = low selenium concentration, ≠≠ HSe = high selenium concentration. T1 = (basal diet, no additive), T2 = T1 + 100 mg Zn + 1.5 mg Cr/Kg diet (Zn-Cr), T3 = T1 + 0.6 mg Se/Kg, T4 = T1 + 0.9 mg Se/Kg, T5 = T1 + (100 mg Zn + 1.5 mg Cr + 0.6 mg Se) and T6 = T1 + (100 mg Zn + 1.5 mgCr + 0.9 mg Se).
