Results of 16S rRNA gene sequence of the rumen bacteria in the susceptible (SUS) and tolerant (TOL) cows. (A) Principal coordinate analysis (PCoA) based on the operational taxonomic units (OTU) level of the bacteria in the SUS and TOL groups. (S1-4: SUS1-4; T1-4: TOL1-4) (B) Venn diagram based on the average reads of bacteria community in the rumen. (C) The significantly different (P < 0.05) OTU (>0.1% at least one group) in the rumen bacteria between the SUS and TOL groups. (D) The relative abundance of Lactobacillus between the SUS and TOL groups.
