Phylogenetic classification and metaproteomics analyses of rumen fluid microbiota of beef cattle fed a CrPyr supplementation diet. (A,B) show phylum-level (A) and genus-level (B) rumen fluid community composition based on Illumina sequences of 16S rDNA amplicons (V3–V4 region). (C,D) show relative abundances of total identified proteins in rumen fluid assigned to bacterial phyla (C) and genera (D). (E,F) show relative abundances of differentially expressed proteins in rumen fluid assigned to bacterial phyla (E) and genera (F). CG, control group; EG, experimental group, diet supplemented with 60 g/day CrPyr. n = 3 per group. *P < 0.05.
