Rumen microbiota composition of the high- and low-weight groups. (A) Bar plot of the mean relative abundance differences of the same species between groups. The y-axis indicates the species names at different taxonomic levels, and the x-axis shows the percentage abundance of a species in the sample. (B) KEGG pathway functional composition and changes in the composition of the dominant pathways. (C) Analysis of the differential pathways associated with the microbiota/function composition. *P < 0.05 indicates a significant difference. **P < 0.01 and ***P < 0.001 indicate very significant differences. (D) The bar chart shows the contributions of species to different functions at the species level. 1–10 represent 10 functional classifications, and 11 different colors represent the degree of species contribution under each functional classification
