African swine fever wild virus and vaccine virus generally need to test 3 genes to distinguish, with CD2v gene or MGF360 gene or two all do to test, wild virus three genes are positive, vaccine virus CD2v/MGF360 is negative. African swine fever is a disease caused by the African swine fever virus. Sick pigs will have fever, loss of appetite, lack of spirit, respiratory difficulties and other symptoms, as well as purple spots in the ears and nose.

First, the distinction between African swine fever wild virus and vaccine poison

1, the distinction between the method

Generally, three genes can be detected to distinguish between the African swine fever wild virus and vaccine poison, with the p72 gene detection of the African swine fever virus, and then with the CD2v gene or MGF360 genes or the two full to do the detection of the infected is the wild virus or vaccine, the wild virus three genes are all the same, the wild virus and vaccine, the wild virus, the wild virus is not the same as the vaccine, and the vaccine. vaccine, wild virus three genes are positive, vaccine virus CD2v/MGF360 is negative.

2, African swine fever Introduction

(1) African swine fever is a key prevention of a class of animal diseases, its pathogenesis is short, the most acute as well as the mortality rate of acute infection up to 100%, it is caused by the African swine fever virus disease.

(2) The disease mainly affects the spleen, lymph nodes, kidneys, liver, heart and other parts of the pig, the sick pig's body temperature will rise to 41-42 ℃, appetite obviously reduced, no spirit, and there will be respiratory symptoms, and at the same time, in the ears, nose, legs, abdomen and armpits and other parts of the body there will be a clear purple spot.

(3) Generally, sick pigs die on the seventh day after the onset of fever, or 1-2 days after the appearance of symptoms.

Second, swine fever special drugs

1, the treatment of swine fever special drugs

Treatment of swine fever is generally no special drugs, usually more to prevent the main, usually can be injected with swine fever vaccine for prevention. Swine fever is caused by swine fever virus is an acute, fever, high contact infectious disease, the infectious, morbidity and mortality are high.

2, the method of preventing swine fever

(1) the implementation of self-propagation, if you need to buy from the field of pig breeding, transported back to the need to isolate about half a month of rearing, to determine the disease-free and injected with vaccines, to be able to mix the group rearing.

(2) Do a good job of sanitizing the pig pen, the surrounding environment, management tools, regular disinfection, timely cleaning of feces, to avoid bacterial growth.

(3) After the occurrence of swine fever, a large dose of swine fever vaccine (10-30 portions) can be used for intramuscular injection, the dose is generally 0.5 portions/kg body weight.
