Means with different letters within the same row differ (P < 0.05).
Control = basal diet; CB1 = the basal diet supplemented with 2.5 × 10⁸ cfu of C. butyricum/kg; CB2 = the basal diet supplemented with 5 × 10⁸ cfu of C. butyricum/kg; CB3 = the basal diet supplemented with 1 × 10⁹ cfu of C. butyricum/kg; Antibiotic = the basal diet supplemented with 150 mg of aureomycin/kg.
c = cis; t = trans.
^aEach value represents the mean of 8 cages with one chick per cage (n = 8 per treatment).
