Bacterial community compositions and potential function in the rumen epithelial fractions under the three treatments. The bacterial community compositions in the rumen epithelial fractions of the UC, LU and HU treatments at the phylum (A) and genus (B) levels. Comparison of the bacterial communities of epithelial fractions based on Bray–Curtis dissimilarity matrix (C), unweighted UniFrac distance (D) and weighted UniFrac distance (E). Heatmap (F) showing differential taxa in the epithelium fractions among the three treatments. PCoA (G) plot revealing differences in predicted microbial functions based on Bray–Curtis dissimilarity matrix. Heatmap (H) revealing the differences of the predictive function profiles at KEGG level 2 in the rumen solid fractions among the three treatments. * p < 0.05, ** p < 0.01. UC, basal diet with no urea; LU, basal diet supplemented with a low concentration of urea (10 g/kg DM); HU, basal diet supplemented with a high concentration of urea (30 g/kg DM).
