Comparison of the fecal microbiomes of abscessed and normal steers. A the ANOSIM R scores (blue line, left y-axis) for the comparison between samples from normal and abscessed animals from the S1-control treatment at different timepoints. The red line and right y-axis show the corresponding p-values. The dashed line indicates an ANOSIM p-value of 0.05. B, E and F Like A but for animals from the S1-tylosin, S2-control and S2-narasin treatments. C The average Bray–Curtis dissimilarity between all pairwise comparisons between samples from the S1-control treatment as a function of time on diet. Colors indicate samples from abscessed or normal steers. The bands around each line indicate the 95% confidence interval for the mean. D, G and H Like C but for samples from the S1-tylosin, S2-control and S2-narasin treatments. * in panels D and H indicate a p-value < 0.05 for PERMDISP tests between abscess and normal beta-diversity values at the indicated timepoints
