A trial was conducted to study the sensitivity of the Aujeszky disease virus, present in the blood of pigs, to the effect of two preservatives: potassium thiosulphate ( K2S2O5 ) and hydrogen chloride (HCl). The sensitivity of the virus was determined on rabbits infected with pig blood containing Aujeszky disease virus with different additions of the two preservatives. As found, 0.5% of K2S2O5 and 3% of HCl are concentrations fully sufficient for the inactivation of all the viruses present in the blood. Blood preserved in this way can be used for feeding purposes in pig stocks without the hazard of introducing Aujeszky disease in healthy stocks via the blood included in feed rations.
进行了一项试验，以研究猪血液中存在的奥耶斯基病病毒对两种防腐剂：硫代硫酸钾（K2S2O5）和氯化氢（HCl）作用的敏感性。通过用含有不同添加量两种防腐剂的感染猪血液的兔子来确定病毒的敏感性。结果发现，0.5%的K2S2O5和3%的HCl浓度足以完全灭活血液中存在的所有病毒。以这种方式保存的血液可用于猪群的饲养，而不会因饲料中的血液将奥耶斯基病引入健康猪群。
