The effects of the addition of different proportions (0%, 5%, 10%, and 15%) of whole-plant corn silage on the fecal microflora of Hezuo pigs. (a) Microorganism rarefaction curves based on observed indices were used to assess the depth of coverage of each sample (samples are distinguished by different colored lines). (b) A Venn diagram showing the fecal microbial operational taxonomic unit (OTU) composition of the control (CON) group and the 5%, 10%, and 15% whole-plant corn silage supplementation groups. The samples were obtained from six Hezuo pigs in each group before the end of the test.
