The effect of dietary ellagic acid (EA) supplementation and fecal microbiota transplantation (FMT) on the gut microbiota in weanling piglets. (A) Rarefaction curve of species counts. (B) Venn diagram of OTU distribution among groups. (C) The structure shifts (beta diversity) presented by PCoA plot based on Bray–Curtis distances and assessed by PERMANOVA analysis. Ctrl, the control group, where piglets were fed the basal diet; EA, the EA group, where piglets were fed the basal diet supplemented with EA; FEA, the FEA group, where piglets were fed the basal diet and received FMT from EA-treated piglets. OTU = operational taxonomic units; PCoA = principal coordinates analysis. Data presented as mean ± SEM. (n = 7).
