Figure 3.

Rarefaction curves (A) and principal coordinates analysis (PCoA) plots of weighted (B) and unweighted (C) UniFrac distances of ileal microbial communities from weanling pigs fed diets containing antibiotics or direct-fed microbials. While two diversity measures (observed OTU; Chao1) were not different due to sex, phylogenetic distance (PD whole tree) showed a trend (P = 0.061) for greater diversity in barrows vs. gilts. Unweighted and weighted UniFrac distances performed on the 97% OTU abundance matrix showed that sexes tended to be different from one another (unweighted: P = 0.02; weighted: P = 0.01).
