a, b Within a column, means ± SE with different superscripts are significantly different (P ≤ 0.05, one-way ANOVA followed by Tukey–Kramer test P < 0.05; n = 12/treatment).

The starter diets were fed from 1 to 21 d (0.41 and 6.62 mg/kg DON) and the grower diets were fed from 22 to 34 d (0.54 and 7.90 mg/kg DON). The DON-diets were prepared with wheat naturally contaminated with Fusarium mycotoxins.
