Don't raise the leftover pigs under non-plague, because the leftover pigs under non-plague may not be infected, but they may be tolerant after infection, and their appearance is healthy, but they may induce non-plague again, so it is not recommended to raise them.

The symptoms of African swine fever include skin redness, vomiting, fever, collapse, rectal bleeding, dyspnea, loss of appetite, and elevated body temperature. There is no treatment for African swine fever at present, and it can only be prevented by disinfection and isolation.

Extended data:

On May 24th, 20 19, the African swine fever vaccine independently developed by Harbin Veterinary Research Institute of Chinese Academy of Agricultural Sciences achieved initial results. China has made five major advances in the development stage of African swine fever vaccine:

One is to isolate the first African swine fever virus in China. The virus cell isolation and culture system and animal infection model were established, and its biological characteristics such as infectivity, pathogenicity and transmission ability were systematically studied.

The second is to create a candidate vaccine for African swine fever. Laboratory studies have proved that the two candidate vaccine strains have good biological safety and immune protection effects.

Thirdly, the two candidate vaccine strains have strong genetic stability in vitro and in vivo. The two candidate vaccine strains have been continuously passaged in primary cells in vitro, and their biological characteristics and genome sequences have not changed significantly, but they have been continuously passaged in pigs.

Fourthly, the minimum protective inoculation dose is defined, which proves that large dose and repeated dose inoculation are safe.

The fifth is to initially complete the technical research of pre-clinical pilot products. The seed bank of two candidate vaccines has been established, the purity of seed batches for vaccine production and the inspection of exogenous viruses have been initially completed, and the cell culture and freeze-drying process of candidate vaccines have been initially optimized.
