Effect of P. acidilactici LC-9-1 on gut microbiota in broilers at 42 d of age (n = 6). (A) Chao1 index of OUT level; (B) Shannon index of OUT level; (C) coverage index of OUT level; (D) number of OTUs; E&F, β-diversity was estimated by the PCA (E) and PCOA (F) on OUT level; (G,H) relative abundance of bacteria, (G) at the phylumand level and (H) at genus level; (I) cladogram of LEfSe multi-level species difference discriminant analysis (LDA > 2), different-color nodes indicate microbial communities that are significantly enriched in the corresponding groups and significantly different between groups; (J,K) comparative analysis of the relative abundance of bacteria, (J) at the phylum level and (K) at genus level.
