The differences in rectal microbiota structure and differentially abundant between HS and HSB groups (n = 9). A Linear discriminant analysis Effect Size (LEfSe) analysis between HS and HAB group. Co-occurrence network and network roles of the top 100 ASVs in the HS (B) and HSB (C) groups. Nodes represent ASVs, and the color of connecting lines indicates positive or negative correlations (Spearman, P < 0.05). No network hubs were identified in networks from both groups. HS means fed a starch-rich diet. HSB means fed a starch-rich diet supply 4 g/d bile acids for dairy goats every day
