Microbiota alpha-diversity comparison among five groups. Pigs were regarded as the experimental units, each treatment with n = 8 except that PC with n = 7 due to a sample was eliminated. (A–C) PD, Shannon index, and Observed_species of five groups, respectively. NC = negative control, no antibiotics; PC = positive control, antibiotics included; OA1 = NC plus organic acid 1; OA3 = NC plus organic acid 3; OA1 + OA3 = NC plus organic acid 1 and organic acid 3.
