Abstract

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.
