This invention discloses a culture medium and cultivation method for promoting the development of Haemonchus contortus larvae, belonging to the field of biotechnology. This invention discovers that compound vitamins and / or bovine liver extract powder as auxiliary components can promote the development of early fourth-stage larvae of Haemonchus contortus into late fourth-stage larvae and adults. This invention provides a culture medium and cultivation method for promoting the development of Haemonchus contortus larvae. The culture medium includes a basal culture medium and auxiliary components, including compound vitamins, bovine liver extract powder, pyruvate, non-essential amino acids, L-glutamine, fetal bovine serum, defibrinated sheep blood, and L-glutathione. The cultivation method includes the step of adding early fourth-stage larvae to the culture medium for cultivation. This invention enables the in vitro culture of adult Haemonchus contortus, which is beneficial for promoting the development of related drugs and vaccines for this parasite and has significant implications for the prevention and control of parasitic diseases.

The invention discloses a health-preserving compound preparation based on deer viscera as well as a preparation method and application thereof, and the health-preserving compound preparation comprises the following raw materials in parts by weight: 25-35 parts of deer heart blood freeze-dried powder, 20-30 parts of deer bone collagen peptide powder, 25-50 parts of deer viscera superfine powder and 5-10 parts of auxiliary materials, the superfine powder of the deer viscera is a mixture of three or more of the following raw materials: superfine powder of a deer heart extract, superfine powder of a deer liver extract, superfine powder of a deer kidney extract, superfine powder of a deer spleen extract and superfine powder of a deer lung extract. The problems that existing deer-derived products are single in raw material, unreasonable in compatibility, serious in thermal damage in the preparation process, low in bioavailability, limited in function dimension and the like are solved.
