【Abstract】 one-day AA broilers were randomly divided into 2 groups, i.e. control group and test group, 72 broilers for each group, each group was divided into 2 duplications and each duplication had 36 broilers. The broilers in the control group were fed on basal diet, while the broilers in the test group were fed on the basal diet with added 1.5% bee pollen. 6 broilers in each group were dissected each week to get their spleens weighted and sectioned. The results showed that the bee pollen could promote the growth and development of spleen, the averaged weight and relative weight of immune organ of broilers in the test group with added 1.5% bee pollen were clearly higher than that of the control group, and the difference was significant (P<0.05); broilers in the test group had a spleen with more developed white pulp, bigger volume of splenic nodule, clearer germinal center, thicker lymph sheath around artery and denser lymphocyte.更多还原
