入孵鹅卵携带鹅细小病毒的比较试验

The Comparison Experiment Of Goose Parvovirus(GPV)Carried By Goose Hatchingegg From Market and that Of Immunized Goose

从由市场收购鹅卵入孵的孵房内采集不同胚龄期的鹅胚蛋,将蛋壳、尿囊液、羊水及胚体制成被检样品,以敏感鹅胚进行小鹅瘟病毒的分离和检测,结果表明小鹅瘟病毒可以由污染蛋壳随着胚龄的增大而侵入胚体,而免疫鹅只所产蛋在不同胚龄期的上述组织中均不能分离到病毒。因此,对种鹅实施健康监控及对种蛋、孵抱设施、市场等施以严格消毒在防治小鹅瘟上有积极意义。
