Differential abundance analysis of the bacterial taxa in the intestinal microbiomes of the three groups. a OTUs differentially represented at the genus level in Landrace, Duroc, and Yorkshire pigs, as identified by LEfSe. Histogram showing OTUs that were more abundant in Landrace (green color), Yorkshire (blue color) or Duroc (red color) pigs, ranked by effect size. b Phylogenetic tree of the microbial communities in the three groups. The phylogenetic tree with taxonomic nodes, where the diameter of the nodes indicates the relative abundance, shows the intestinal microbiota of Landrace, Duroc and Yorkshire pigs. Different groups are labeled with different colors. The red areas indicate that the species of bacteria were more abundant in Duroc pigs, the blue areas indicate that the species of bacteria were more abundant in Yorkshire pigs, and the green areas indicate that the bacteria were more abundant in Landrace pigs
