Effect of Prevotella and sodium succinate on the gut microbiota. A Venn diagram illustrated the overlap of operational taxonomic unit (OTU) in all tested chicken. B The composition of gut microbiota of community bar plot analysis on phylum level. C Heatmap hierarchical cluster analysis based on the 20 most abundant phylum among groups. D Linear discriminant analysis effect size (LEfSe) analyses (LDA score ≥ 4.0) at the phylum level to the genus level. E Cladogram generated from LEfSe analysis (LDA score ≥ 4.0). Different color nodes represent the significant enriched microbial groups in the corresponding treatment groups which have a significant impact on the differences among groups, and the diameters of the circles are proportional to the axon’s abundance
