Definitely not, there are no effective drugs and vaccines** and prevention of African swine fever, and intelligence starts from biosecurity. Pig herd disinfection strengthens the immune system of the pig herd, improves the resistance of the pig herd, avoids the stress reaction of the pig herd in the breeding process, and carries out regular disinfection. Disinfection of the empty houseAfter the transfer of the pigs, the pig house is disinfected, the ceiling of the pig house is cleaned, the dust and cobwebs are removed, and then the ground, the pig pen and the equipment in the house are washed, and the equipment that can be disassembled is removed and disinfected with disinfectant for about a day, and then cleaned with water.
Paint the walls of the pig house with lime powder, close the pig house tightly, spray aldehyde preparations, kill the microorganisms in the pig house, and then empty for about a week, and then put the pigs in after the disinfectant effect disappears. Drinking water disinfection is selected to disinfect the drinking water of pigs with disinfectants that have no effect on pigs, so as to eliminate microorganisms in drinking water and reduce the incidence of respiratory diseases and digestive diseases. Environmental disinfection disinfects the surrounding environment of breeding personnel, transport vehicles, and pig houses, and splashes lime powder at a distance of 500-1000m from the farm to prevent the spread of the virus.
Try not to choose a variety of disinfectants when disinfection, so as to avoid the acid-base neutralization effect and reduce the disinfection effect.

**There is no rule that prohibits rural pig breeding, but it is strictly forbidden to raise pigs with kitchen waste in rural areas.
Due to the outbreak of African swine fever, on the afternoon of January 8, 2019, the Ministry of Agriculture and Rural Affairs organized a national remote training on African swine fever prevention and control, focusing on implementing the main responsibility of animal epidemic prevention and strengthening the epidemic prevention management of large-scale pig farms and breeding pig farms.
Pig farmers should resolutely overcome the luck mentality, strictly implement the main responsibility of animal epidemic prevention, and consciously accept the supervision and inspection of the veterinary department. It is necessary to further improve the epidemic prevention system, strictly clean and disinfect vehicle personnel, put an end to the use of kitchen residues to feed pigs, and resolutely block the transmission route of the epidemic.
It is necessary to strengthen personnel training, standardize epidemic investigation reports, and never allow the epidemic to be concealed. At the same time, it is necessary to improve the predictability of the market situation, seize the opportunity, actively fill the column, stabilize the sow herd, and properly make good pig production arrangements.
Yu Kangzhen, Vice Minister of the Ministry of Agriculture and Rural Affairs, pointed out that through the joint efforts of all parties, the current national epidemic situation is in a state of sporadic sporadic sporadic occurrence, and the momentum of the epidemic has begun to slow down, and the epidemic is generally controllable.
The market for pork products is sufficient and continues to be stable. However, at the same time, it is necessary to see that the traditional breeding structure is difficult to fundamentally change in a short period of time, the channels of epidemic transmission and return are complex, and the prevention and control situation is still complex and severe.

<> how long it takes for an outbreak of African swine fever to recover from a farm depends on factors such as the degree of infection. After the outbreak of swine fever, the pigs should be killed, and the epidemic should be reported to the relevant departments and the pig farm should be fully disinfected immediately, if there is no new epidemic after 42 days, it can be introduced into the sentry pig after the provisions of the measures, and if the sentry pig does not have abnormal symptoms and the pathogen test is negative, then you can consider starting to resume breeding.
1. How long can a farm with African swine fever raise pigs?
1, the farm after the outbreak of African swine fever after the specific need to be determined by the degree of infection and other factors, there is no standard answer, according to the relevant provisions of the country, once the African swine fever virus occurred in the pig farm, to kill all the pigs in the field, and the swine fever epidemic reported to the relevant departments, the first time to disinfect all the pig farms for disinfection and harmless treatment, after 42 days if no new epidemic is found, you can be disinfected and harmless according to the regulations, 15 days later can be introduced"Sentinel pigs" continue to be raised, and if these "sentinel pigs" do not show some clinical signs of swine fever and the etiological test is negative, they can be considered to resume production.
2. African swine fever is a hemorrhagic, acute and virulent infectious disease caused by African swine fever virus infecting domestic pigs and various wild boars (such as European wild boar, African wild boar, etc.). The virus can be confirmed from the tissue fluid, blood, internal organs, and other excreta of infected pigs, and the virus can survive in the blood in the low-temperature dark room for six years, and can live for several weeks at room temperature, heating the infected blood to 60 (10 minutes) or 55 (30 minutes), the virus will be destroyed, and many disinfectants and lipid solvents can destroy it.
2. Prevention and control measures for swine fever
1. It is forbidden for outsiders, vehicles and other poultry to enter the clean pigsty, and the car should be disinfected when entering the pig farm, and the pigs can not be fed with swill, it is easy to carry the virus, do not raise pigs freely, wild boars or external insects will cause pigs to get sick, observe the situation of pigs at any time, such as high fever, vomiting, redness and diarrhea, and do a good job of isolation in time to deal with it as soon as possible to reduce losses.
2, regular preventive injection, spring and autumn every year, in addition to adult pigs generally carried out a swine fever rabbit attenuated vaccine injection, weaned piglets and newly purchased pigs should be timely epidemic prevention injection, the newly purchased pigs should be isolated for 30 days, confirmed disease-free, and injected swine fever vaccine can be mixed after the group, swine fever often epidemic areas, piglets are born 21-30 days old injection once, 55-60 days old piglets weaned and injected again.
3. After the occurrence of swine fever, it is necessary to clean up in time, the feed and utensils of the farm should be disinfected, and the farm should be closed when the disease breaks out, which can reduce the invasion of viruses and insects and other wild poisons, and pigs with low immunity are prone to disease.

The swine fever virus can only infect pigs and cause swine fever, not chickens, in other words, chicken fever will not cause swine fever in pigs.
Swine fever only infects pigs under natural conditions, and pigs of different ages, sexes, breeds and wild boars are susceptible and can occur all year round. Sick pigs are the main source of infection, sick pig excrement and secretions, sick and dead pigs and organs and corpses, blood, meat, internal organs, wastewater, waste material contaminated feed of sick pigs, drinking water can spread the virus, the spread of swine fever is mainly through contact, through the digestive tract infection.

1. Pig farms to achieve automatic management, reduce the entry and exit of personnel, is a more direct way to deal with African swine fever, the mobility of personnel will bring certain bacteria to the pig farm, causing pig infection, African swine fever is a more difficult disease, so want to stay away from the flow of African swine fever personnel to control.
2. The disinfection system of the pig farm should be in place, especially the import and export of the pig farm to do a good job of epidemic prevention, the import of the pig farm is the first line of defense of the entire pig farm, which plays a very important step for the entire pig farm.
3. Use automatic feeding line equipment to keep the feed fresh, make the pigs eat healthily, and reduce the infection of mosquitoes and plague can also effectively avoid the spread of plague. The existence of African swine fever will continue for some time, and the farms still cannot relax!
If the pig farm is closed too strictly, it is very likely that swine fever will occur, because the seal is too strict, the air inside is not circulated, the temperature is too high, and the density of the pig is large, so there will be a bad smell of gas inside, and it is very likely that swine fever will occur for a long time, threatening the life and health of pigs, so it is important to ensure the ventilation of the pig farm and do a good job of hygiene!
African swine fever in sows.
Initial symptoms include increased body temperature and dyspnea. >>>More
Rural free-range, due to the low feeding density, coupled with free-range, pigs have stronger immunity and stronger resistance to African swine fever virus, and will persist for a longer time overall. However, if we only compare the number of pig farms that have been recruited, "rural pigs" are still much higher than large-scale pig farms, and there are even pig-free villages in many places. It's just that due to the large number of "rural pigs", the remaining number is not expensive. >>>More
1. Disinfection work.
Due to the nature of African swine fever, other pigs can still be contaminated in the pigsty contaminated by the virus, so the contaminated pigsty should be thoroughly cleaned and the pig house should be fully disinfected. Generally, disinfectant is used for disinfection, and because the African swine fever virus is not heat-resistant, it can also be disinfected by steaming, boiling, burning, etc. >>>More
The incubation period of African swine fever is generally about 5 to 19 days, and the length of the incubation period is related to many factors such as the viral impact of swine fever virus and the disease resistance of infected pigs. At present, there is no ** swine fever drug, if you find an infected sick pig, you must contact the local department as soon as possible to sanitize the treatment. >>>More
