| 摘 要： | 为研究鸭禽流感免疫程序,对不同日龄的雏鸭进行禽流感母源抗体的检测,并对雏鸭接种禽流感H5、H9二价油乳剂苗后的HI抗体水平进行了检测。结果表明,雏鸭的母源抗体水平在1日龄达最高值,然后逐渐下降;H5抗体20日龄后降低到4.5log2以下,H9抗体25日龄后降低到4.8log2以下。根据试验采用的免疫方案,对雏鸭在8日龄时进行首免,并多次免疫后可提高H5、H9抗体水平,有效预防禽流感的发生。 |

| Abstract: | The Avian influenza maternal antibody and HI antibody of duck were 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 maternal antibody level was highest in 1-day-age duck and cut down gradually.The maternal antibody of H5 in duck was decreased to 4.5log2 after 20-day-age and maternal antibody of H9 was decreased to 4.8log2 after 25-day-age.The duck could get high HI antibody level of H5 and H9 by first immunize... |
