Effects of dietary Trollius chinensis Bunge residue supplementation on  cecal microbiota in weaned rabbits
In our study, 8081 ASV were obtained through sequencing, with the number of operational taxonomic units decreasing as TCBR concentration increased. ASV Venn analysis identified 2 174, 2 169, 1 948, and 451 unique ASV in the Mock, TCBR2, TCBR4, and TCBR6 groups, respectively. Compared with the Mock group, both the ACE and Chao1 indexes were reduced in the TCBR6 groups. The Shannon and Simpson indexes were lower in all TCBR-treated groups relative to the Mock group. Moreover, the goods_coverage index is above 0.98 for all samples. that indicated high coverage of species in the samples and reasonable sequencing depths. Principal coordinate analysis indicated a progressive shift in the microbial community with increasing dietary TCBR levels .
