Diversity analysis, differential and functional enrichment analysis of cecal microbes. A The alpha diversity of cecal microbiota was analyzed by Chao1, Simpson, Shannon, ACE. Red is CON group and blue is the SIL group. B Differences of cecal flora at phylum level. C The beta diversity of cecal microbiota was analyzed by PCoA. D The different microbial groups in cecum of laying hens were analyzed based on LEfSe method. E The circos map of functional component relationships F CON group vs. SIL group comparison between different functional units. G The comparison of gene expression enriched in secondary bile acid biosynthesis (pink for CON group, yellow for SIL group). PCoA, Principal coordinates analysis; LEfSe, Linear discriminant analysis effect size
