  1. #Group 1 represents samples collected from pigs treated with antibiotics 105 mg/d. Group 2 represents samples collected from pigs treated with L. plantarum ZJ316 1 × 109 CFU/d. Group 2-1 represents samples collected immediately after the cessation of L. plantarum and Group 2-2 represents samples collected one week after the cessation of L. plantarum. All values represent mean ± standard error.
  2. a, b and c Different superscript letters within a row represent statistically significant differences among groups (p < 0.05).
