^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 five piglets. ³ ADFI: average daily feed intake; ADG: average daily gain; F/G: ratio of feed to weight gain.
