Immunological enhancement composition and application thereof

Abstract

The invention provides an immunological enhancement composition and application thereof. The immunological enhancement composition comprises lycium barbarum glycopeptide LbGp4 and auxiliary materials; the mass ratio of the lycium barbarum glycopeptide to the auxiliary materials is 5: 1, and the purity of the lycium barbarum glycopeptide is greater than or equal to 90%. CY is adopted to induce chicks to generate an immunosuppression state, the antagonism of LbGp4 on immunosuppression is studied, and the result shows that the LbGp4 can remarkably improve the growth performance of the chicks induced by CY to generate immunosuppression, remarkably promote spleen development and accelerate the recovery process of spleen injury caused by CY; the multiplication capacity of CY-induced immunosuppression chick peripheral blood lymphocytes is remarkably improved, and the effect is the best when the LbGp4 medium dose group (5mg / kg.d) is adopted. According to the results, the immunological enhancement composition provided by the invention can be applied to preparation of the medicine for improving the immunity of the chicks.

Description

technical field [0001] This application relates to the technical field of animal health care, in particular to an immune enhancing composition and its application. Background technique [0002] Immunosuppression refers to the existence of immune dysfunction in the animal body, resulting in decreased immunity, which makes it more vulnerable to pathogens. The brooding period of chicks usually refers to the period from newborn to the seventh week, which is characterized by fast growth and poor resistance. Therefore, in order to have good production performance during the laying period, in addition to providing a good growth environment in the early stage, strengthening early feeding management and biosecurity measures is also the top priority. Although maternal antibodies can protect chicks from early infection, as the maternal antibodies gradually weaken, the protection also weakens, so there will be a period of immune blank period. Early immunization of chicks is also an es...
