Composition containing heparin sodium enzymatic hydrolysate, and preparation method and application of composition

The invention belongs to the technical field of heparin sodium products, and particularly relates to a composition containing heparin sodium enzymatic hydrolysate, and a preparation method and application of the composition. According to the composition, heparin sodium enzymatic hydrolysate is used as a solvent; nutritional ingredients such as proteins, saccharides and the like are added and reasonably matched; and then the composition is solidified into a semi-solid state by utilizing glucolactone. After the composition is taken by cultured animals, the feed intake and the weight of the cultured animals can be remarkably improved, and the feed conversion ratio and the diarrhea rate are reduced. The composition is relatively easy to store, transport and use due to the semi-solid state, andthe content of effective components is basically unchanged after the feed is placed for 7 days. In addition, a relatively good nutritional and health-care effect can be kept, decay and stink are avoided, and the stability is
