摘  要:
目前,我国猪场伪狂犬病野毒感染情况非常普遍,阳性率几乎是100%,但大部分是带毒不发病的平衡状态。这对猪场是潜在的威胁,同时也对免疫工作提出了更高的要求,母猪群体每年的免疫次数达到3次~4次,仔猪同样也要进行2次~3次免疫。部分猪场进行伪狂犬病野毒的净化,仔猪伪狂犬病疫苗喷鼻免疫是至关重要的,仔猪出生1 d~3 d后就可进行喷鼻免疫,提前占位,让疫苗先抢占野毒感染的位点,避免感染,为伪狂犬病野毒的净化打下基础。

摘  要:
The infection of pseudorabies virus in pig farm is very common, the positive rate is almost 100%, but most of them are in the state of non disease with virus, in a balanced state, but it is a potential threat to the pig farm, and the requirements for vaccine immunization have been improved. The number of times of immunization for sows every year reaches 3-4, and piglets also need 2-3 times of immunization. In view of this situation, it is very important for piglets to be immunized with Pseudorabies Vaccine by nasal spray in some pig farms. The piglets are immunized by nasal spray in 1-3 days after birth to occupy the position ahead of time, so that the vaccine virus can occupy the site of wild virus infection first and avoid the infection of wild virus. Therefore, nasal spray is very important in the whole process to provide the basis for the purification of pseudorabies wild virus
