为探讨科学的鸡新城疫免疫程序，对1～28日龄的土杂肉鸡和罗曼蛋鸡进行新城疫母源抗体的检测，并对两种雏鸡接种新城疫冻干疫苗和油乳剂疫苗后的HI抗体水平进行了检测。结果表明，两种雏鸡的母源抗体水平在1日龄时均达最高值，然后逐渐下降；肉鸡11日龄后降低到5．210g2以下，蛋鸡28日龄后降低到4．310g2以下。分别对肉鸡在12日龄时进行首免，蛋鸡在11日龄时进行提前首免可获得较高的抗体水平，根据试验所用的免疫方案，可有效预防鸡新城疫的发生。

The New castle disease maternal antibody and HI antibody of 1-28-day-age Broiler chicken and Luoman chicken were respectively detected to institute this scientific immune program. New castle disease freeze dried vaccine and oil emulsion vaccine were used in the test. The results showed that the maternal antibody level was highest in 1-day-age chicken and declined gradually. The maternal antibody of Broiler chicken decreased to 5.21og2 in 11-day-age and that of Luoman chicken was decreased to 4.31og2 in 28-day-age. Broiler chicken and Luoman chicken could get high HI antibody level by respectively first immunized in 12-day-age and l 1-day-age. The immune program used in the test could efficiently prevent new castle disease.
