| 摘 要： | 应用琼脂免疫扩散试验对不同种鸡场四批不同品种的1日龄雏鸡IBD母源抗体阳性率进行监测,结果分别为55％、95％、50％和35％。同一鸡群内其琼扩抗体水平为0—1:32不等,差异较大。其母源抗体琼扩阳性率呈线型下降,阳性率消失时间长短不一,最长在25日龄前后完全消失。4批鸡群,分别在10、22、10、5日龄时,其母源抗体阳性率下降20％,即可进行IBD的首次免疫。

| Abstract: | One - day chicks' positive rate of IBD maternal antibody was detected with agar gel immunodittusion test in four groups. The result was 55%, 95%, 50% and 35%, respectively. The agar gel immunodittusion antibody titers varied from 0 t 0 to 1 : 32 in the same group. The positive rate of IBD maternal antibody was linear dropping, and disappering time was different. The longest time was about 25 days. When the positive rate of IBD maternal antibody came to 20%, the first IBD vaccination was done on 10, 22, 10, 5 days in the four groups. |
