Fig. 4From: Effects of dietary supplementation of probiotic Enterococcus faecium on growth performance and gut microbiota in weaned pigletsDistribution of bacterial community structure at phylum level in different phases. The relative abundances lower than 0.01% are not shown. 1 day, 7 days, and 14 days represent experimental day 1, 7, and 14, respectively. The relative abundance at phylum level was statistically analyzed through non-parametric Kruskal–Wallis testsBack to article page
