A Changes in the relative abundance of bacterial taxa (at phylum level) during the earliest life period through parturition and weaning of the first litter (3–53 weeks of age). B–F Mean relative abundance of bacterial genera, showing increases or decreases within each of the top 5 phyla (blue and gray lines represent individual genera whose abundances significantly increased or decreased over time). G, H Top seven genera collectively from the phyla Firmicutes and Bacteroidetes, with the highest relative abundance that either increased or decreased over time
