1Each mean represents 6 birds. NC = birds fed a basal diet without challenged with E. coli K88; PC = birds fed a basal diet and challenged with E. coli K88. CB = birds fed a basal diet including 2 × 107 CFU C. butyricum/kg of diet and challenged with E. coli K88. CS = birds fed a basal diet including 20 mg colistin sulfate/kg of diet and challenged with E. coli K88
