1 Bacterial taxa present at relative abundances of greater than 0.5% and the proportion of unidentified bacteria is 0.022%; 2 C = basal diet; 3 A = basal diet supplemented with 30 mg/kg bacitracin; 4 BLF = basal diet supplemented with 1 g/kg BLF; 5 AF = basal diet supplemented with 15 mg/kg bacitracin and 0.5 g/kg BLF; 6 SEM = standard error of mean; 7 adjusted p value: false discovery rate correction using the Benjamini–Hochberg procedure; 8 data are mean values of 3 replicate per treatment (2 piglets per replicate); a–c means that have no superscript in common are significantly different from each other (p < 0.05).
