摘要
选择自然发病鸡有典型病变之法氏囊.研制了油乳剂组织灭活苗,试验接种健康雏鸡第10、20、30、60、90和120天后,其血清AGP抗体阳性率分别为20%、50%、100%、100%、100%和70%。免疫后第60天攻击IBD强毒,保护率为100%,对鸡无毒副作用,室温保存12个月不影响免疫效果。
The oil-adjuvant inactivated vaccine against IBD was preparated with bursal tissue from natural cases. The immune experiment shows that the positive rate of AGP in the chicken serum is 100% on pastinoculation the 30th day. The experiment is infected by IBD violent virus on the 60th day and the protective rate is 100%.
