In order to evaluate the efficiency for extracting nucleic acids of African swine fever virus(ASFV)from pig products,the pseudoviral particles were mixed with the experimental materials including fresh pork,sausage and blood powder to prepare relevant simulated infection samples,and then ASFV nucleic acids were extracted by nucleic acid free extraction,column nucleic acid extraction and magnetic bead adsorption nucleic acid extraction methods,to calculate the recovery rate and to evaluate the extraction efficiency. The results showed that ASFV nucleic acids could be detected from the supernatant and precipitation of the simulated samples,and more in the former as compared with the latter. All the three methods were suitable for the supernatant of sausage samples,in which the column extraction method was the best,with a virus recovery rate of 82.8%;magnetic bead adsorption nucleic acid extraction method was the best for the supernatant of fresh pork samples,with a recovery rate of 20.9%;and the column nucleic acid extraction method was for that of the blood powder samples,with a recovery rate of 10.2%. A reference was thus provided for extracting ASFV nucleic acids from different pig products.
