Fig. 6

Microbial functions and species involved in carbohydrate metabolism, energy metabolism and other processes in the rumen of the cows with high (HRFI) and low residual feed intake (LRFI). Among the genes encoding enzymes involved in the fructose and mannose metabolism pathway, 8 genes tended to be more abundant in the HRFI cows. In the glycolysis pathway, the abundance of 4 genes tended to be higher in the HRFI cows (P < 0.10), and 1 gene was more abundant in the HRFI cows (P = 0.03). In the pentose phosphate pathway, 2 genes tended to be more abundant in the HRFI group (P < 0.10), and 5 genes were enriched in the HRFI group (P < 0.05). Three genes involved in quorum sensing pathways, and 6 genes involved in methane metabolism were significantly enriched in the HRFI cows. In the butyrate metabolism pathway, 4 genes tended to be more abundant in HRFI cows (P < 0.10), and 3 genes related to butyrate production were significantly enriched in HRFI cows (P < 0.05). The blue text represents the genes or metabolites enriched in HRFI cows, and the red (orange) text indicates the genes or metabolites enriched or tended to be enriched in LRFI cows. The text in brackets under the gene name is HRFI/LRFI fold change of gene. The text over the arrow is the gene code. Inside the pink rectangles are the microorganisms that play an important role in the pathway
