Percent Abundance Plots for Predominant Bacteria. For yearlings (blue) and adults (red), the percent abundance of bacterial populations was plotted as means ± SEM over time for Phyla Actinobacteria (a), Bacteroidetes (b), Fibroacteres (c), Firmicutes (d), Proteobacteria (e), Spirochaetes (f), and Verrucomicrobia (g). Friedman and Kruskal–Wallis analyses were performed with Dunn’s multiple comparison tests (a, contrast pDunn’s < 0.05 compared with Day 28 within yearlings)
