Application of mycoplasma hyorhinis P37 protein in preparation of animal vaccine adjuvant, animal vaccine adjuvant and application thereof

The invention belongs to the field of biotechnology and immunology, and particularly relates to application of mycoplasma hyorhinis P37 protein in preparation of an animal vaccine adjuvant, the animal vaccine adjuvant and application of the animal vaccine adjuvant. The mycoplasma hyorhinis P37 protein is used as an active component to prepare the animal vaccine adjuvant, and experiments prove that the obtained animal vaccine adjuvant has biological viscosity and can generate a slow release effect after being injected, so that an antigen is continuously and effectively released, the action time of a vaccine is prolonged, the burst release effect is avoided, the concentration of an effective product is maintained, and the immune effect of the vaccine is improved; the antibody can be generated after 7 days of immunization, the immune protection antibody level can be completely reached after two weeks, and the immunization duration is long; moreover, the immunopotentiator is easy to absorb, free of toxic and side
