Linear discrimination analysis (LDA) coupled with effect size (LEfSe) analysis of the rumen microbial community of lamb between grass and concentrate groups. A Cladogram showing microbial species with significant differences among the two treatment groups. Red, and green represent different groups. Species classification at the phylum, class, order, family and genus level are displayed from inner to outer layers. The red and green and blue nodes represent microbial species in the phylogenetic tree that play important roles in the grass and concentrate groups, respectively. Yellow nodes represent no significant difference between species. B Significantly different species with an LDA score greater than the estimated value (default score = 3.5). The length of the histogram represents the LDA score of different species in the two groups. G, grass group; C, concentrate group
