摘　　要：将480只8日龄的从肉仔鸡随机分为4个处理，每处理6重复，每重复20只，于12日龄和28日龄各处理每只鸡分别接种不同剂量新城疫疫苗（0、4、6、8羽份），研究其对肉仔鸡生产性能及免疫后0～48h血浆皮质酮、胰岛素、葡萄糖、总蛋白、总胆固醇、甘油三酯和游离脂肪酸水平的影响。结果表明，新城疫疫苗免疫显著降低肉仔鸡8～21日龄的体增重和饲料效率（P〈0．05），但适当剂量的免疫接种（4羽份和6羽份）可明显降低21-42日龄和8～42日龄的料重比；高剂量免疫接种（8羽份）会改变肉仔鸡神经内分泌，引发免疫应激，趋于降低生长性能，但不影响血液中代谢产物的浓度。480 eight-day-age broilers were randomly divided into 4 groups and inoculated with 0,4,6,8 doses Newcastle disease vaccine at 12 d and 28 d,respectively,with 6 replicates of 20 broilers each from 8 to 42 d of age. Plasma were analyzed for corticosterone,insalin,glucose,total protein,eholesterol,triglyeerides and nonesterified fatty acid in 0 to 48 h after each inoculation. The results showed that Newcastle disease vaccine inoculation decreased daily weight gain and feed conversion ratio from 8 to 21 d （P〈0.05）,while 4 and 6 doses of inoculation reduced feed intake/body weight gain from 21 to 42 d and 8 to 42 d. High level of NDV could alter neuroendoerine,whieh resulted in immunological stress and tended to decrease body weight gain,but had no effect on plasma metabolite profiles.
