The ratio of “Functional Group 2/Functional Group 1” reflects the functional characteristics of the microbiota. A and B PCoA analysis of the abundance of CAZy genes in different dietary groups. Samples with “high Functional Group 2” or “high Functional Group 1” were marked with different colors. C and D Relative abundance of CAZy genes for a particular substrate in different dietary groups. E The relative abundance of key enzyme genes associated with the production of acetate (FTHFS: acetyl-formyltetrahydrofolate synthase/formate-tetrahydrofolate ligase), propionate (PcoAt: propionyl-CoA:succinate-CoA transferase/propionate CoA-transferase), and butyrate (Buk, butyrate kinase; AtoA, acetoacetate CoA transferase beta subunit; and AtoD, acetoacetate CoA transferase alpha subunit) in different dietary groups based on KEGG orthologous groups. F and G PCoA analysis of genes encoding virulence factors in different dietary groups. Samples with “high Functional Group 2” or “high Functional Group 1” were marked with different colors. H Chao1 index analysis of virulence factor gene abundance. I and J The relative abundance of each class of virulence factor genes in different dietary groups at week 1 (I) and week 3 (J). K The richness and diversity of antibiotic resistance genes were analyzed by Chao1 and Shannon indices, respectively. L The relative abundance of each class of antibiotic resistance genes in different dietary groups. ARGs with relative abundance below 1 in 100,000 were excluded in the analysis
