(A) Principal component analysis (PCA) based on non-phylogenetic Bray–Curtis distance metrics for the overall fecal antimicrobial resistance genes between the control (CONT) and tulathromycin (TUL) piglets. (B) Principal component analysis (PCA) for the overall fecal antimicrobial resistance genes across all samples at different sampling days (0, 5, and 20). The percent variation explained by each component is indicated on the axes. Significance between the two groups was analyzed using PERMANOVA with 9999 permutations and Bonferroni corrected P-values.
