摘要: 用新支流三联苗(批号200701)免疫AA+父母代肉种鸡,子代雏鸡1日龄母源抗体的变化情况与其种鸡血清抗体的消长情况相似,呈强正相关。1日龄雏鸡母源抗体平均滴度越高,其15~17日龄后下降越迅速,至28日龄时已接近为0。结果表明,种鸡免疫后1~3个月,其子代在14日龄内的母源抗体可对ND的攻击获得全保护,传染性支气管炎母源抗体≥6log2。种鸡免疫后4~4.5个月,其子代对ND、IB的攻击在7日龄内能全保护。证明三联疫苗免疫种鸡后1~3个月可保护子代抵抗病毒攻击至14日龄;免疫后4~4.5个月,其子代可保护至7日龄;而免疫后5~6个月可保护子代至1日龄。

Abstract: After AA+ breed hens were immunized using NDV-IBV-AIV(H9) vaccine, the HI antibody of one-day-old chicklings and breed hens were positive correlation. One-day-old chicklings maternal HI antibody was higher and its maternal declined fast after 15-17-day-old.The chicklings maternal HI antibody against NDV, IBV and H9 subtype AIV were 0. The result indicated that the young than 14-day-old chicklings could get 100% protection against NDV, IBV and H9 subtype AIV within 60 days post immunization. Young than 7-day-old chicklings could get 100% protection within 120 to 135 days post immunization; 1-day-old chickling could get 100% protection within 150 to 180 days after breed hen immunized.
