• Chinese herbal medicine extracts
• antibiotic combination
• fecal microorganism
• pigs
• tetracycline-resistant gene

This study was designed to evaluate the effects of Macleaya cordata extracts (Chinese herbal medicine extracts) and antibiotics combination with chlortetracycline (CTC) on the antibiotic resistance genes in fecal microorganism. Compared with the group without antibiotics, the relative abundances of all six tetracycline resistance genes were increased after 75 mg kg(-1) CTC supplementation. Interestingly, M. cordata extracts in feed suppressed the increase of a part of tetracycline resistance genes in fecal microorganism of weaned pigs.
