Patent ID: 11471529

Abstract:
The present invention relates to the preparation of the compound immunopotentiator and the application thereof in a foot-and-mouth disease vaccine of pigs. According to the present invention, the foot-and-mouth disease vaccine of pigs is taken as a research subject, and on this basis, several immunopotentiators having obvious immunopotentiating effects are selected for the compound immunopotentiator, and an antigen/vaccine is mixed with the immunopotentiator to prepare a vaccine-immunized pig. An animal experiment result shows that the present invention has obvious immunopotentiating effects. After immunizing the vaccine containing the compound immunopotentiator, a window period for antibody production can be significantly shortened to 7 days; a LPB-ELISA antibody titer is significantly improved, and an antibody pass rate is significantly increased; an immune protection period is also significantly extended, at least up to 7 months.
