Note: Group A (as control) was fed a basal diet, the treatment groups (B, C and D) were fed the basal diet supplemented with 250 mg/kg Clostridium butyricum (viable count 3.0 × 10⁶ CFU/g), 250 mg/kg Bacillus subtilis (viable count 2.0 × 10⁷ CFU/g), or the combination of 250 mg/kg Clostridium butyricum plus 250 mg/kg Bacillus subtilis, respectively. The different superscripts in the same row denote the means are significantly different between the groups (p < 0.05). The data are presented as the mean ± SEM. n = 6. W/L denotes the weight/length ratio of each intestinal segment.
