Production method of suckling piglets

The invention relates to a production method of suckling piglets, and belongs to the technical field of vertebrate breeding. The production method comprises the following steps that an additive adopting glycyrrhiza polysaccharide and glycyrrhizic acid as the main components is added into basic rations of the suckling piglets so that the suckling piglets can freely eat the rations; the addition amount of the glycyrrhiza polysaccharide is 0.275-2.95% of the mass of the basic rations; and the mass ratio of the glycyrrhiza polysaccharide to the glycyrrhizic acid in the additive is (5-16): 1. According to the production method, the additive adopting the glycyrrhiza polysaccharide and the glycyrrhizic acid as the main components is added into the basic rations of the suckling piglets so that thesuckling piglets can freely eat the rations, the food consumption of the piglets can be improved, the blood sugar level and the serum oxidation resistance capacity can be improved, and therefore theweight of the suckling pig
