Comparison of bacterial phyla, genera and species between the cows with high (HRFI) and low residual feed intake (LRFI). The difference of bacterial phyla (A) and genera (B) were tested by Wilcoxon rank-sum test, *P < 0.05, **P < 0.01. (C) Significant different bacterial species. Significant differences were tested by linear discriminant analysis effect size (LEfSe) analysis, with linear discriminant analysis (LDA) score of > 2 and P value of < 0.05
