Maternal microbial effects. (a) PERMANOVA results quantifying the differences (variance explained, R2) in overall microbiota composition by sow/piglet per niche at each time point. Higher R2 values indicate that differences between piglets and sows explain more variance for a given niche at a given time point. (b) Venn diagrams showing the S0 (postpartum stage of the sow) and O1 (5 day old) stage core microbiota (75% sample prevalence). (c) Donut charts demonstrate the relative abundance of the top 15 genera. P-values were generated using a permutation test. ***P < 0.001.
