Functional microbial taxa capable of fiber degradation are differentially abundant in the GIT microbiome of FF and SF goats. A Phylogenetic tree of 1029 metagenome-assembled genomes (MAGs). The outer strip chart indicates the class-level affiliations of MAGs, and the height of the outermost bar represents the genome size. B Correlation network of metabolic pathways and genomes, with genomes colored according to taxonomic information; Heatmap for selected key CAZyme families in differentially enriched genomes in SF or FF ruminal microbiome (C) and SF or FF cecal microbiome (E); Heatmap for selected key metabolic genes in differentially enriched genomes in SF or FF ruminal microbiome (D) and SF or FF cecal microbiome (F), key metabolic genes include SCFA production, energy generating and cobalamin biosynthesis
