a statistical trendP = 0.058
As a result, the NMDS based on the Bray–Curtis distance of relative abundance of ASV showed a distinct microbial structure related to treatments on day 8 post-farrowing (PERMANOVA: P = 0.026; ANOSIM: P = 0.018), reaching a statistical trend on day 21 post-farrowing (PERMANOVA: P = 0.058; ANOSIM: P = 0.074).
