Abstract: The published clinical trial about treatment of weaned piglet stage with Chinese herbal medicine were systemically evaluated by meta-analysis method, in order to provide valuable reference for treatment of weaning piglet health care. The clinical randomised controlled trials (RCTs) about treatment were searched completely from databases of Science Direct, Web of Science, CNKI, Wanfang Database, VIP Database, etc, using the Review Manager 5.3 software recommended by the Cochrane Collaboration. A total of 27 RCTs and 1 870 weaned piglets were included, among them, 935 weaned piglets in treatment group treated with Chinese herbal medicine, 935 weaned piglets in control group treated with chlortetracycline, colistin sulfate, colistin sulfate + bacitracin zinc. Results showed that:the daily weight gain effect of Chinese medicine group was better than the overall antibiotic group[SMD=1.22, 95%CI(0.69-1.75), P<0.01], but there is no difference with the chlortetracycline group(P>0.05). The daily feed intake of Chinese medicine group was better than the overall antibiotic group[SMD=0.77, 95%CI (0.34-1.20), P<0.01], but equivalent to the chlortetracycline group (P=0.05).The difference in Feed weight ratio between the Chinese medicine group and the antibiotic group was not significant[SMD=-0.35, 95%CI(-0.78-0.09), P=0.12>0.05], However, it was significantly better than the colistin sulfate and chlortetracycline subgroup (P<0.01).The effect of Chinese medicine on diarrhea rate was significantly lower than antibiotics{SMD=-1.77, 95%CI[-2.52-(-1.01)], P<0.01}, However, the effect was comparable to that of the colistin sulfate + bacitracin group (P>0.05). The Chinese herbal medicine was added at the weaning stage of the piglets. The indexes of daily gain, daily feed intake and diarrhea rate were superior to that of the antibiotic group, that is, the traditional Chinese medicine has the potential of traditional Chinese medicine in the stage of weaning piglets.
