Summary:[Objective] This paper aimed to observe the effects of Qishen ultrafine powder on immune efficacy of infectious bursal disease vaccine in chickens. [ Method] 360 1-day-old chickens were randomly divided into six groups equally, and group I -V were vaccinated with IBD live virus vaccine on the 21 th and 35th day, respectively. From 14th to 21th day, group I - Ⅲ were added with 1%, 0.5% of Qishen ultrafine powder and 2% of Qishan powder in basel diet, respectively, group IV was given Yupingfeng oral liquid and group VI was as a control group without vaccination. Be- fore the expedment （14-day-old chickens as DO ） and 7 （ D7 ）, 14 （ D14 ）, 21 （ D21 ）, 28 （ D26 ）, 35 （ D36 ）, 42 （ D42 ） days after the experiment, the dynamic change of serum IBD specific antibody was determined, respectively. On D7, D21 and D36, the dynamic change of peripheral T lymphocyte proliferation and IL-2 in serum were determined, respectively. The weight change was also observed. [Results] Compared with the immune control group, the immune effects of IBD vaccine of each administration group were significantly improved, and there was no significant difference between each other. [ Condusion] Qishen ultrafine powder could increase immune function of chickens at lower dosage.
