¹ Data are means with the SEM derived from ANOVA error mean square for n = 10. ² I-Se, basal diet containing 0.2 mg/kg sodium selenite; O-Se, basal diet containing 0.2 mg/kg selenium yeast; I-Se + pros, basal diet containing 0.2 mg/kg sodium selenite and 0.5% probiotics; O-Se + pros, basal diet containing 0.2 mg/kg selenium yeast and 0.5% probiotics. ³ Se-S, Main effect of selenium source; Pros, Main effect of probiotics; Se-S + Pros, Main effect of selenium source plus probiotics. ⁴ Interaction between Se source and probiotics level. ⁵ V = Villus height; ⁶ C = Crypt depth; ⁷ V/C = Villus height: Crypt depth. ^a,b Means within the same row having different superscripts differ significantly (p < 0.05).
