Use of beta-glucan extract in the immunopotentiation of an avian animal

Abstract

The present invention relates to use of β-glucan extracts in the immunopotentiation of an avian animal. Specifically, the present invention provides a kit, wherein the kit comprises (1) an immunopotentiator used for immunopotentiation of an avian animal, wherein the immunopotentiator comprises a β-glucan extract which is extracted from Saccharomyces cerevisiae cell wall; and (2) a virus vaccine. The present invention also provides use of a β-glucan extract which is extracted from Saccharomyces cerevisiae cell wall, in the preparation of a kit used for immunopotentiation of an avian animal and immunopotentiator. The present invention uses a β-glucan extract, which is extracted from Saccharomyces cerevisiae cell wall, for immunopotentiation of an avian animal, which can enhance lymphocyte proliferation responses and T cell responses of vaccinated animals; decrease the viral load; reduce the morbidity or mortality; produce antibodies in advance; and increase antibody production; and/or restrict the spread of the virus.
