为探讨科学的鸡禽流感免疫程序,对1～28日龄的土杂肉鸡和罗曼蛋鸡进行禽流感母源抗体检测,以及对雏鸡接种禽流感油乳剂疫苗后的HI抗体水平变化进行了监测。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H5、H9抗体滴度分别降低到4.2log2和4.3log2以下;蛋鸡28日龄后H5、H9抗体滴度分别降低到4.2log2和4.8log2以下;分别对肉鸡在11日龄时进行首免,蛋鸡在7日龄时进行提前首免后均可获得较高的抗体水平;同时根据试验所用的免疫方案,可有效预防鸡禽流感的发生。

The Avian Influenza maternal antibody and HI antibody of 1～28-day-age Broiler chicken and Luoman chicken were respectively detected to institute scientific immune program.Avian Influenza oil emulsion vaccine of H5 and H9 were used in the test.The results showed that the H5 and H9 maternal antibody level were highest in 1-day-age chicken and cut down gradually.The H5 and H9 maternal antibody in Broiler chicken were respectively decreased to 4.2log2 and 4.3log2 after 11-day-age and that of Luoman chicken were decreased to 4.2log2 and 4.8log2 after 28-day-age.Broiler chicken and Luoman chicken could be respectively first immunized in 11-day-age and 7-day-age.The immune program used in the test could usefully prevent Avian Influenza in chichen.
