Fig. 1

Compositions of the fecal microbiota of the LRFI and HRFI pigs. The number of phylum (a) and genera (b) shared by the two groups are shown in Venn diagrams. The different colors represent different groups, the numbers in the overlapping part represent the number of species in two groups, and the numbers in the non-overlapping parts represent the number of species unique to the corresponding group. The overall compositions of the fecal microbiota of the LRFI and HRFI groups were represented as bar plots at the phyla (c) and the genus level (d). The different colors represent the columns, and the length of the columns represent the proportion of the species in the two groups
