C. PCoA, based on the weighted UniFrac distance matrix, of the bacterial 16S rRNA gene sequence data or the rumen, ileum, and colon, combined data (C). D. Microbial dissimilarity (calculated based on the weighted UniFrac distance matrix, 100 values in each group) between the male and CtM groups in the different intestinal compartments. The lines, boxes, and whiskers in the box plot diagrams represent the median, first and third quartiles, and min-to-max distribution of replicate values, respectively.
