| 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. |
