¹Treatments were: H0, basal diet without MetaSmart^® H15, basal diet supplemented with 15 g/d MetaSmart^® H30, basal diet supplemented with 30 g/d MetaSmart^®.

²SEM, standard error of the mean.

³Significant at P ≤ 0.05.

^{a, b}Means within a row followed by different lower-case letters differ significantly from each other (P < 0.05).
