SFR changed carbohydrate metabolism and amino acid metabolism in ruminal microbiota according to metagenomic information. Comparisons of the relative abundance of KO enzymes, which related to metabolic pathways for carbohydrate fermentation and amino acid biosynthesis by microbial cross-feeding in the CON and SFR groups by the MannâWhiney U test (n = 5 per group). Red font indicated upregulated enzyme genes while blue font indicated downregulated enzyme genes
