On the day of the first immunity, 3 d before the second immunity, the day of the second immunity and 3 d after the second immunity, high-dose concentration and low-dose concen- tration of Astragalus polysaccharide （ASP）, Epimedium polysaccharide （EPP） and Isatis roots polysaccharide （IRPS） were used for the immunity groups of each Chi- nese medicine using the gavage, and 0.5 ml for each chick, and the equivalent normal saline was used for the blank control group and vaccine control group. On the 7^th, 14^th, 21^st and 28^th day after the first immunity, 10 chicken of each group were randomly got and weighed, and the antibody titer and the changes of the pro- liferation of T lymphocyte were measured. The results showed that 3 kinds of Chi- nese medicine polysaccharides all can increase the weight of chicken, improve HI antibody titer of Newcastle disease, and promote the proliferation of peripheral T lymphocyte, in which the effect of IRPS at low dosage is the best.展开更多
