鸡新城疫气溶胶免疫(气雾免疫),自推广以来,经十多年的考验,证明是一种省工、省力、能迅速产生较强免疫力的好方法。近年来在应用过程中遇到一些新问题,现针对喷雾器械;疫苗和剂量;疫苗稀释方法;雾室小气候;诱发病及预防措施等,做一些探讨,供参考。一、喷雾器械的选择鸡瘟气雾免疫所使用的器械,大体为两类。一类是以气泵为动力,通过离心吹气和负压作用,将苗液吸出,形成气溶胶;另一类采用 E 型电磁铁,驱动衔铁,作用于柱塞泵往复运动为动力,产生高压达到高速喷射,由喷咀形
Newcastle disease of chicken immune aerosol (aerosol immunization), since its promotion, after more than 10 years of tests proved to be a labor-saving, labor-saving, can produce a strong immune system a good way. In recent years, some new problems have been encountered in the application process, and some discussions are made for reference on the spraying equipment, the vaccine and the dosage, the vaccine dilution method, the microclimate in the fog chamber, the induced diseases and preventive measures. First, the choice of spray equipment Chicken blast aerosol immunosuppressive devices, generally two categories. One is based on the pump as the driving force, through centrifugal blow and negative pressure effect, the seedling liquid aspirated, the formation of aerosols; another type of E-type electromagnets, the armature drive, acting on the plunger pump reciprocating motive force, resulting in high pressure Achieve high-speed jet, shaped by the nozzle
