Effects of adding 0.08%COS to the diet on the rumen microbial community of beef cattle (n = 6). (a) α-Diversity index, including Chao 1, observed_species, PD_whole_tree, and Shannon. (b) β-Diversity index, PCoA analysis based on Bray-Curtis distance. The composition of rumen bacterial communities (top 20) at the phylum level (c) and genus level (d). The differential microbial communities between the two treatment groups at the phylum level (e) and genus level (f). And the “*” in (e,f), respectively, represent: * (0.05 < p < 0.1), ** (0.01 < p < 0.05), *** (p < 0.01).
