(A) Principal coordinate analysis (PCA) of the functional diversity in the GI tract of steers. Treated steers were given antibiotic feed additives and control steers were the control animals. The rumen microbiome samples, except for NA-04, clustered together and separated from cecum and colon samples. Comparison of functional genes that are significantly different (p < 0.05) between NA (blue bars) and AB steers (red bars) (B) in rumen (C) colon and D) cecum are given above.
