^cCON, piglets fed the basal diet; AB, piglets fed the basal diet supplemented with 75 mg chlortetracycline and 20 mg enramycin per kilogram; CB, piglets fed the basal diet supplemented with C. butyricum preparation;

^dDiarrhea score = sum of the fecal score / number of test piglets; fecal score: 0, normal; 1, soft feces; 2, mild diarrhea; and 3, severe diarrhea
