摘　　要：随机选取1日龄塞北乌骨鸡240只,随机分为4组,每组60只,在同一饲养条件下,每组鸡按常规免疫程序进行基础免疫后,饲养至35日龄,分别用2、3、4、5倍剂量新城疫疫苗滴鼻接种,测定血清抗体效价和免疫器官指数。结果表明:3倍量的新城疫疫苗滴鼻免疫塞北乌骨鸡产生的抗体效价显著高于其他各组,对免疫器官指数的促进作用也明显,是适宜的免疫剂量。240 1-day-old Saibei Silkies were divided into 4 groups randomly, 60 for every group in av- erage. They were intranasal inoculated with 2NDV （Newcastle Disease Vaccine）, 3NDV, 4NDV, 5NDV on 35 days in the same breeding conditions and basic immunization. The antibody titer and immune organ index was determined. The results showed that the antibody titer and the immune organs index of 3NDV inoculation were significantly higher than the other groups. It was appropriate for Saibei slikies.
