Differences in OTUs of ruminal bacteria between the control feeding group (CONT) and calcium propionate supplementation feeding group (PROP). (A) Venn diagram showing the number of shared OTU between feeding groups. (B) Principal coordinate analysis (PCoA) of bacterial community structures of the ruminal microbiota of the two groups. The PCoA plots were constructed using the unweighted UniFrac method. Blue squares and red circles represent PROP and CONT feeding group samples, respectively. (C) Thermal double dendrogram of the most abundant bacterial operational taxonomic units (OTU).
