a–c Different superscripts within a row indicate a significant difference (p < 0.05). 1 Dietary treatments: CON = basal diet; AGP = basal diet supplemented with 0.075 g/kg chlortetracycline, 0.055 g/kg kitasamycin, and 0.01 g/kg virginiamycin; CBN = basal diet supplemented with 2.5 × 108 CFU/kg C. butyricum; CBH = basal diet supplemented with 2.5 × 109 CFU/kg C. butyricum. 2 SE: standard error of the mean. Each treatment group contains six replicates (n = 6), and each replicate includes one piglet.
