Comparisons of bacterial alpha diversity in the lumen of the jejunum, ileum, and cecum. a Changes in intestinal lumen microbiota alpha-diversity (Shannon index) for different microbiota input groups throughout the 6-week trial period for both T1 and T2. Comparisons between Shannon indices between microbiota input groups, weeks, and trials were made using an analysis of variance (ANOVA) followed by subsequent pairwise comparisons with the Tukey’s “Honest Significant Difference” method. Significance bars with an asterisk (*) indicate difference between microbiota input groups and/or time points (P < 0.05). b Stacked barcharts comparing the relative abundance of bacterial families representing > 0.01 (1%) of the lumenal bacterial community in any gut compartment within T1 or T2 at weeks 1, 3, and 6
