PCV2通过人工受精使母猪感染的可能性以及对公猪精液质量的影响
总之,PCV2阳性公猪可通过人工授精将病毒传播给母猪,病引起繁殖障碍。没有证据表明精液中的PCV2对精子细胞的特征有影响。而且,PCV2疫苗不会改变精子质量。

本文讲述了PCV2 的分泌路径,传播途径 和危险因素,以及PCV2成为致病性病原的原因
和患病毒血症仔猪的平均病毒数(柱体)对比值。两项指标都是通过对3周龄仔猪接种疫苗和未接种疫苗的猪群实施定量聚合酶链反应测得的。_51521.jpg?w=650&h=366&ho=1&t=1653979446)
避免PCV2导致的生产损失,最有效的途径就是防控病毒血症,通过主动或被动免疫减少病毒在猪场的传播。
