[ Method] One hun- dred 1 -day-old healthy Sanhuang chickens were randomly divided into five groups, 20 in each group. They were immunized with Newcastle disease vaccine via intranasal inoculation at 7 days old. The chickens in group I, II and III drank water added the Danggguibuxue decoction at proportion of 2%, 5% and 10% （ V/V）, respectively. The chickens in the group IV drank water added Astragalus polysaccharide at proportion of 2% （V/V）. And those in the group V drank water without addition of any drug. Blood was collected via jugular vein at 14, 21 and 28 days old, respectively, and then they were dissected. The immune organ indexes, erythrocyte C3b receptor rosette rate （E-C3b RR） and erythrocyte immune complex rosette rate （E-ICRR） were measured. [ Result] The Dangguibuxue decoction had no significant effect on thymus index but significantly increased spleen index and bursa of Fabricius index. The best peripheral and humoral immunity was observed in the broilers drinking water added the Dangguibuxue decoction at proportion of 10% （ V/ V）, and its immune enhancement was better than that of Astragalus polysaccharide added at proportion of 2% （V/V）. [ Coaclusion] Dangguibuxue decoction can promote maturation of immune organs and enhance erythrocyte immune functions; thus, it can be used as immunolootentiator.展开更多
