How to prevent swine fever How to prevent swine fever

A: At present, there is no effective method for the disease, mainly relying on the usual prevention. The specific measures are:

Regular vaccination, in spring and autumn every year, in addition to the adult pigs generally carried out a swine fever rabbit attenuated vaccine injection, weaned piglets and newly purchased pigs should be timely vaccinated and injected. The rabbitized attenuated swine fever vaccine was diluted with normal saline according to the instructions of the bottle label, and 1 ml of intramuscular injection was injected into both large and small pigs, and immunity could be produced 4 days after injection. In areas where swine fever is common, piglets are injected once at the age of 25 to 30 days after birth, and piglets at the age of 55 to 60 days are injected again after weaning, and the protection rate can reach 100%.

Vaccination of pregnant sows can enhance the ability of mothers and children to resist swine fever virus. Vaccinations are usually given one and a half months before farrowing. Emergency immunization, in the pig herd where the epidemic has occurred, do emergency preventive injection, can play a role in controlling the epidemic and preventing the spread of the epidemic, the injection can start from the pigs in the surrounding disease-free areas and disease-free pig houses, and then inject the same group of pigs, and the sick pigs are generally not injected.

In order to strengthen immunity, the dose can be increased appropriately at the time of injection. Strengthen feeding management, regularly disinfect pigsties, improve the overall disease resistance of the pig herd, and eliminate the purchase of pigs from epidemic areas. Newly purchased pigs should be isolated for 30 days to confirm that they are disease-free, and can only be mixed after being injected with swine fever vaccine.

During the swine fever epidemic, feeding utensils are disinfected every 3 5 days. After the disinfection of sick pigs, completely eliminate manure and dirt, remove topsoil, pad new soil, and pig manure should be accumulated and fermented.

The African swine fever vaccine has been developed, and if you are not at ease, you can use the African swine fever detector of Fengtu.

At present, there is no special method for swine fever, and comprehensive prevention and control measures based on immunization must be taken. Specific measures include:

1) Vaccination: Qualified areas, pig farming communities and pig farms can use swine fever immunization monitoring methods to carry out timely immunization according to the law of swine fever antibody levels. Immunotiter monitoring methods can be used for indirect hemagglutination assay or enzyme-linked immunosorbent assay for swine fever.

If antibody monitoring is not available, two immunization schedules can be adopted depending on whether sporadic swine fever occurs in the area: aIn areas and farms where piglets are swine fever is sporadic, pre-lactation immunization methods should be used, and piglets should be vaccinated against swine fever before eating colostrum, and each piglet should be injected with 1 serving.

b.In areas and farms where the prevention and control of swine fever is good and there is no sporadic piglet swine fever, the swine fever vaccine can be immunized once at the age of 20 days and 60 days respectively. Gilts for breeding are injected again at the age of 6 months.

Breeding herds are vaccinated against swine fever twice a year. In the process of immunization, the vaccine dose should be sufficient, the needle length should be appropriate, and no flying needles should be given to ensure the immunization effect.

2) Quarantine and purification: regularly monitor the blood collection of breeding pigs, and identify and eliminate pigs with strong antibodies to swine fever and pigs with multiple immunosuppression, purify the pig herd, and eliminate the hidden danger of swine fever.

3) Strengthen vaccine management: Vaccines are purchased from the main channels. The vaccine is diluted and used, and the vaccine should not be separated from the ice bucket and the bucket should be kept from the ice to ensure that the vaccine is effective, and it is strictly forbidden to use expired vaccines and vacuum-losing vaccines.

4) Strengthen the disinfection of needles, needles and injection sites used in immunization to reduce the spread of man-made diseases.

5) Emergency vaccination: emergency vaccination should be taken in the affected areas and fields, and the vaccine dose should be appropriately increased (can be increased by 1 3 times) to reduce the incidence of disease and control the spread of the epidemic.

6) Strengthen the treatment of sick and dead pigs: isolate suspected sick pigs. Dead pigs and pollutants must be treated harmlessly, and it is strictly forbidden to eat them.

7) Strengthen the disinfection of the environment inside and outside the venue: the whole site environment is disinfected once every month or half a month; At least once a week, the pig house is disinfected with pigs; Feeding utensils are disinfected every 2 3 days; The disinfection pool at the entrance of the field and the entrance of each building should be changed frequently to keep the disinfectant effective.

8) Strengthen management and improve the individual disease resistance of pigs. Provide the best living conditions, protect against the cold in winter, prevent heat in summer, and have fresh air in the house.

9) adhere to self-breeding, it is strictly forbidden to purchase commercial pigs, the introduction of breeding should be introduced from non-epidemic areas, after the introduction of quarantine observation for more than 1 month, swine fever virulent antibody negative, swine fever vaccine immunization can only enter.

First of all, disinfect 3-5 times a day, during which the pathogenic microorganisms of the pig farm should be thoroughly purified, continuously disinfected for about 7 days, and then reduced to 1 disinfection per day to prevent the pathogenic microorganisms from coming in, until the end of the swine fever, and then insist on disinfection for more than 15 days, and then return to the normal disinfection time, the gate disinfection pool can be diluted with glutaraldehyde 1:1000 times for spray disinfection, and vehicle disinfection can be diluted with glutaraldehyde 1:1000 times for spray disinfection. Then use astragalus mixture or water to fight viruses daily.

Pig farmers to effectively prevent swine fever must first strengthen the management of feeding, add mold remover to the feed, do a good job in feed mold repellent, in one is to enhance the pig's own immunity, can be used under astragalus, multi-dimensional and so on. It is also necessary to disinfect and clean the pigsty regularly. The better disinfection brands include potassium persulfate or glutaraldehyde methylammonium bromide, etc., and secondly, it is necessary to ensure that the temperature of the pigsty is suitable and good ventilation.

Swine fever is a disease that has been circulating in pig herds for many years and is also known as the classic swine fever virus. Direct contact with the virus, or contact with contaminated vectors, can cause the occurrence and epidemic of swine fever. The main routes of infection are the digestive tract, nasal mucosa, and ruptured **.

The onset of the disease does not have obvious seasonality, and the rainy season in spring and summer is the prone period. Usually only pigs are susceptible, and all pigs and wild boars have the potential to become infected. The main infection of swine fever ** is sick pigs, and the excretions and secretions of sick pigs, sick si

Pigs and organs and carcasses, blood, meat, offal, waste water, waste contaminated feed and drinking water from slaughtered pigs can all be used as vectors.

Recommendations; Non-plague clearing: the amount of non-plague prevention is 2-3 kg tons of material), which is used for 7-14 days per month; ** The amount of non-plague is 4-5 kg tons of material), and it is used for 7 days; It is suitable for farmed animals of all ages.

It is used for the prevention and prevention of febrile (distemper) diseases caused by African swine fever, swine fever, blue ear, ring, streptococcus, influenza, epierythroid, toxoplasma and mixed sensitia. Symptoms: high fever and dizziness, mental atrophy, conjunctival flushing, hyperemia; **Redness, bleeding and bruising on the body surface, especially severe in the limbs, lower abdomen, perineum, buttocks and other parts; coughing, wheezing, difficulty breathing; vomiting, loss of appetite or abolition, hard and dry stools, constipation, or purulent bloody stools; Sows with infertility, abortion, si

Fetus. Necropsy of the patientPigs can see severe enlargement of the spleen, liver, lungs and other organs and lymph nodes, and extensive bleeding and blood stasis.

If there are no antibodies in the pig, the virus will immediately enter the cell and start to multiply, and many markers will appear on the cell surface, and other viruses will not enter the cell; If the virus is released, there is a possibility that other cells will continue to be infected; If the immune system in the pig establishes a specific immune function, it will destroy the cells with immune markers, and the body will show a more severe inflammatory response, and the pig will be in a state of disease.

How to prevent and treat swine fever and can it be cured.

The symptoms of acute swine fever are very obvious, but it is difficult to judge the chronic swine fever (atypical swine fever) in clinical production, so the pathogenesis of chronic swine fever is mainly introduced.

Pigs can be vaccinated, pigs can also be fed with some medicines, the pig house can also be sterilized and disinfected, and the pig house can also be cleaned regularly, so that swine fever can be prevented.

The pigsty should be cleaned frequently, cleaned frequently, the pig should be immediately sick **, and it should be isolated, the pigsty should be disinfected regularly, and the pigs should be vaccinated.

Farmers should clean up the manure pile in time every day, and keep the pig house clean, dry, ventilated, warm and appropriate feeding density to create a suitable environment for pigs. Farmers should disinfect the enclosure utensils, pig pens and pig bodies at least once a week, and choose low-toxicity disinfectants with strong bactericidal power to be used in turn to prevent the emergence of drug resistance.

1. Do a good job in swine fever vaccination and formulate scientific immunization procedures. In particular, it is necessary to grasp the timing of the first immunization. For suckling piglets, sow-derived antibodies, especially colostrum, can be obtained from breast milk.

High-drops of maternal antibodies can control the occurrence of swine fever. 2.Strengthen feeding management to ensure that pigs eat colostrum after lactation, and give lactating sows sufficient nutrition.

3.Strengthen epidemic prevention and quarantine, prevent the introduction of sick pigs from other places, and do a good job in isolation and quarantine. After the outbreak of swine fever, it is necessary to block the epidemic point, prohibit the flow of pigs, and urgently bury and slaughter sick pigs.

4.Thoroughly disinfect the pigsty, bedding, manure and utensils. Feeding utensils are disinfected every 2 3 days;

1.Feed hygiene.

In order to prevent swine fever, it is necessary to ensure the safety of feed and do not provide pigs with some food that is not easy to digest. Generally, pigs can be provided with some energy foods, such as corn, wheat bran, rice bran, etc. But when providing feed, it is necessary to observe whether the food is moldy to avoid stomach upset after eating the pigs.

2.Vaccine protection.

When raising pigs to prevent swine fever, it can also fundamentally solve the problem of prevention, that is, to vaccinate pigs against swine fever and let pigs grow healthily. At the same time, just after vaccination, pigs should be observed for three days to prevent them from developing resistance to vaccines, fainting, vomiting and other phenomena.

3.Disinfection of the pigsty.

Swine fever usually occurs because the environment in which pigs grow is too dirty. Therefore, in order to prevent pigs from contracting swine fever, it is essential to provide a cleaner environment for pigs. It is best to clean the pigsty every other week and ventilate it once a day so that the pigs can grow healthily.

4.Drug. When raising pigs, in order to prevent swine fever, Fuzheng Jiedu powder can also be added to the feed eaten by pigs, but this medicine cannot be used for a long time, so as not to affect the quality of pork. Generally, if you use Fuzheng Jiedu for 15 days in a row, the possibility of swine fever will decrease a lot.

1. Disinfection of pigsty: When preventing and controlling swine fever, it is necessary to disinfect the pens every 2-3 days and clean the utensils. 2. Quarantine and epidemic prevention

Pigs infected with swine fever need to be slaughtered immediately and buried deep to avoid infection. 3. Develop procedures: vaccinate sows and piglets to avoid infection.

4. Strengthen management: let the piglets eat the colostrum of the sow and enhance immunity.

1. Environmental disinfection

If you want to prevent swine fever, the first step is to ensure the hygiene of the environment. We should thoroughly disinfect the pigsty, bedding, manure and utensils, etc., and disinfect the feeding utensils every 2-3 days, shovel the manure on the surface of the pigsty, and fill it with new soil. It can be mixed with caustic lye, bleaching powder, quicklime, etc., and used for spraying and disinfection.

2. Quarantine and epidemic prevention

The second step to prevent swine fever is quarantine and epidemic prevention to prevent foreign sick pigs from entering the pigsty. We must do a good job in isolation and quarantine, prevent the introduction of sick pigs from other places, block the epidemic points in time after the occurrence of swine fever, prohibit the flow of pigs, slaughter sick pigs and bury them deeply, and timely vaccination for healthy pigs for prevention.

3. Formulate procedures

Before swine fever does not occur, we must do a good job of scientific immunization procedures, sows can use the way of vaccination to avoid the possibility of swine fever, and piglets should be used for the first lactation, the first immunization should be selected in the maternal antibody hours before the vaccination, in the effect is about to disappear when the second vaccination.

4. Strengthen management

Strengthen the management of feeding and raise pigs scientifically. During the lactation period, we should give the sows enough nutrients, provide sufficient and nutritious plants, and do not mix pigs and piglets except for lactation, so as to prevent the infection of the diseased strain to the piglets. Give the piglets plenty of breast milk** to strengthen their immunity.

After the diagnosis of swine fever, the pig herd should be inspected first, and the sick pigs should be immediately removed, killed and incinerated or deeply buried.

Isolation and disinfection of sick pig houses; Emergency vaccination of pigs against swine fever in areas where the disease has not yet become ill or threatened. It should be noted that the incidence and mortality of pigs that have been in the incubation period of infection may be accelerated after vaccination, but emergency vaccination can effectively stop the development of swine fever to a certain extent, shorten the epidemic process and reduce economic losses.

Pig farms and feeding management utensils must be strictly disinfected, and 2% sodium hydroxide disinfection effect is better.

Swine fever precautions

1. For farms or areas where pigs must be introduced, the pigs should be fully understood and their health conditions should be fully understood to avoid the introduction of the disease. In addition, personnel and vehicles should be disinfected to prevent the mechanical introduction of the disease.

2. It is necessary to do a good job in vaccination, formulate a strict immunization plan, and ensure vaccination density and regular immunization. During the transportation, storage and use of vaccines, the relevant instructions should be strictly followed to prevent the titer of the vaccine from decreasing or failing.

3. Conscientiously do a good job in veterinary health work and strengthen feeding management.
