nMDS ordination of gut microbial communities from the ileum of birds fed either a barley control diet (filled circles) or barley diet supplemented with enzyme (open squares) showing the extent to which the overall community pattern generated from the full set of 91 OTUs (A) is reproducible by a smaller subset of 17 OTUs (B) identified by the BVSTEP procedure. The matching coefficient (ρ) to panel A is shown in panel B. The subset of 17 OTUs identified consisted of OTUs 70, 96, 148, 182, 184, 190, 214, 224, 286, 288, 290, 300, 480, 522, 580, 590, and 880.
