Spf chickens with 21 - day - old were infected subcutaneously with oil - emulsion vaccine of ibdv of germinal or cellcular and injected intramuscularly with different dosages bursin which gain through ultrafilter. lt is proved that bursin of chickens and ducks can both shorten the time of antibody induced against ibdv, raise the level of serum antibody. they make chickens obtaining strong immunocompetente in a short time. agp liters of the group of infecting 0. 4mlcbs + ibdv of germinal and 0. 8mlcbs + ibdv of cellcular or 0. 8mldbs + ibdv of germinal and cellcular are higher than immune control group about 2 liters averagely. the chickens were inoculated with ibdv live vaccine mixed with the different dosages of lyophilized bursin by the eye drop method. the results sugest that cbs or dbs of different dosages can both improve the antibody inducation to different age chickens against ibdv. they may also alleviate the immunological injury of activated virus to bursa of fabricius. and promote the repairation of the lesion. it can be found that bs can raise body weight gain and feed coversion ratio
