FIG. 3.

nMDS ordination of gut microbial communities from the ceca of birds fed either a barley control diet (filled circles) or a barley diet supplemented with enzyme (open squares) showing the extent to which the overall community pattern identified from the full set of 111 species (A) is reproducible by a smaller subset of 29 species (B) identified by the BVSTEP procedure. The matching coefficient (ρ) to panel A is shown in panel B. The subset of 29 OTUs identified were OTUs 70, 92, 94, 96, 146, 158, 184, 188, 198, 212, 214, 216, 222, 286, 290, 300, 486, 488, 490, 496, 526, 528, 530, 536, 538, 546, 548, 580, and 590.
