Effect of dietary Se-enriched yeast or lactobacilli on ileal bacterial composition in laying hens (n = 8). A Microbial composition in layers’ ileum at the phylum and genus levels under three treatments. B Linear discriminant effect size of ileal microbiota (LDA > 3.0; P < 0.05). C Differences in relative abundance of ileal microbiota at genus level in laying hens from different groups. SeD The basal diet without Se supplementation, SeY15 or SeL15 The diet supplemented with 1.5 mg/kg Se from Se-enriched yeast or Se-enriched lactobacilli
