Aim:to study the practical effect of astragalus polysaccharides(APS) injection as a chicken bird flu immune adjuvants.
Method: divide 60 chicks into 5 groups randomly,do comparative experiments with different doses and injection methods, drawing blood every 7 days after first immunization
conduct the second time immunization on the fifteenth day and drawing the blood two times once again once again and Detect the antibody titer of the serum vaccine.

In order to investigate the plantain polysaccharide can be used as a candidate adjuvant, with Roosters as test animal, from Plantago polysaccharide to chicken blood physiological, biochemical, immune organs, Newcastle disease (ND) on the immune effect of vaccine impact test. The blood physiological and biochemical and immune organ affected by chicken for the same batch, the Fed plantain polysaccharide solution were measured each time the red cell count, serum alanine aminotransferase (GOT), Gu Cao transaminase (GPT), alkaline phosphatase (AKP), albumin and serum calcium levels; Newcastle disease (ND) affects the immune effect of the vaccine trials with another group of chicken, vaccine subcutaneous injection of inoculation, in each period were detected after immunization of chicken ND antibody level and T lymphocyte transformation rate. The results show: the Fed plantain polysaccharide chicken of the immune organs index was significantly higher than the control group, the blood red and white cell counts were higher than those in the blank group. Prompt Plantago polysaccharide can promote the chicken immune organs and red and white cells. Plantago polysaccharide and ND vaccines can increase the serum ND antibody level and T lymphocyte transformation rate. Prompt Plantago polysaccharide has had strong immune protection of ND vaccine.
