摘　　要：研究日粮中添加不同粒度黄芪茎叶粉对蛋用公雏鸡生长及免疫功能的影响。结果表明:随着黄芪茎叶粉粒度变小,公雏鸡体重、血清抗新城疫病毒抗体效价、免疫器官指数均有不同程度地提高。说明随着黄芪茎叶粉粒度变小,不同程度提高了其促生长和增强免疫的功能。The effects of different particle size of powders ot stalks and leaves from Radix Astragali added into daily ration on growth performance and immune function of egg-type young cockerels were studied. The experimental results showed that： a- long with particle size of powders of stalks and leaves from Radix Astragali lessening,the weight,the valences of anti-NDV im- mune body in serum and immune organ index of young cockerels were all increased in varying degrees. Therefore, powders of stalks and leaves from Radix Astragali lessening could improve the growth performance and immunity function of egg-type young cockerels in varying degrees.
