Abstract: In order to select the best dose of certain purified Chinese herbal medicinal compound polysaccharide (cCHMPS), which had been proven to significantly affect the immunity of mice, three hundred one-day-old male Liangfeng Green-feet Ma chickens were randomly divided into six groups, namely control group, levamisole hydrochloride (LM) group, Astragalus polysaccharide (APS) group, high, medium and low-dose purified cCHMPS group, and with 50 chickens for each group. Eight-day-old chickens were vaccined with physiologic saline, LM, APS, high, medium and low-dose purified cCHMPS, once a day for 7 consecutive days. On days 8, 14, 21, 28, 35 and 42 after the first vaccination, 5 chickens' blood for each group were sampled for determination of T, B lymphocyte proliferation activities and NDV antibody levels. The results showed that APS and purified cCHMPS at different doses could significantly or extremely significantly promote the proliferation of peripheral T, B lymphocytes (P<0.05;P<0.01), increase the concentrations of NDV antibody, enhance cellular immunity and humoral immunity, and the medium-dose purified cCHMPS was the best.

Key words: certain purified Chinese herbal medicinal compound polysaccharide; Astragalus polysaccharide; levamisole hydrochloride; cellular immunity; humoral immunity
