摘　　要：目的：通过检测AA肉仔鸡新城疫HI抗体效价的变化，以观察复方杜仲对鸡新城疫疫苗免疫效果的影响。方法：将224只1d龄AA肉鸡随机分成4组，每组56只，即复方杜仲低剂量组、复方杜仲中剂量组、复方杜仲高剂量组和对照组，试验期为42d。每周在各组鸡群中随机抽6只鸡采血，分离血清，测定NDVHI抗体水平。结果：试验组鸡群血清NDVHI抗体水平在试验期内（1—42）d均高于对照组，与对照组比，在注射后2—3周内差异有显著意义，大剂量组P〈0．01，中、低剂量组P〈0．05。结论：在AA肉鸡饮水中添加复方杜仲煎煮液对鸡新城疫疫苗免疫具有明显的免疫增强效果。Objective： AA broilers were fed on Cortex Encomia compound and studied its effect on immune function through detecting HI level of antibody of Newcastle disease（ND）. Methods： Two hundreds and twenty-four AA broilers were randomly divided into four groups, including a control group and three groups given Cortex Encomia compound. All groups had been investigated for 42 days. Every group took the same immunity approaches and blood was taken from AA broiler＇ heart. Results： Mter injection two or three weeks, in the Cortex Encomia compound groups the level of HI antibody were higher than the control group. the controls（ P 〈 0.01 ） ; The low dosage group and the The high dosage group was very remarkable compared to that of middle dosage group were remarkable compared to that of the controls（ P〈 0.05）. Conclusion： Resuhs showed that the Cortex Encomia compound was effective in enhancing immunity for Newcastle disease（ND）.
