Why do pig farms deep in the mountains also get African swine fever epidemics? What causes it?

Our domestic pork ** large **, resulting in many people complaining, now even pork is about to be unaffordable, and the main reason for pork ** is African swine fever, we know that generally viruses like this can only be transmitted between animals after contact, so why do pig farms in the depths of the mountains also get it?

There are three main reasons why pigs raised deep in the mountains can also be infected with swine feverThe first is on the food of pigsWe know that although some pig farms are in the mountains, they are not completely isolated from the outside world, and when they buy feed outdoors, they will come into contact with the pulling cart and related personnel, and often sometimes the virus will inadvertently infect the feed.

The second is waterIn the past, there were many farmers in order to save time and cost, and directly threw the dead animals directly into the river for treatment, in this case, it is still possible to be infected.

In addition, in fact, although many farmers say that they are breeding in the mountains, they also have to buy and sell pigs or piglets, which will inevitably come into contact with the market, and the pig cart and the staff may carry the virus to contact them, which indirectly gives African swine fever an opportunity.

Although the current market is pork ** is more expensive, it is also because during the period when the virus is raging, the state has strict control over this aspect, as long as a way to deal with it is found, the market can recover. Some netizens said: Although I don't know how long it will last, I believe it will definitely be solved.

African swine fever can be transmitted through the air, it can be spread through this food, for example, people who raise pigs deep in the mountains, they also need to buy this feed, these cars are not sterilized, so they bring this virus in.

Pigs are full of bacteria, and although they are deep in the mountains, there are many pigs in the intestines of pigs that can be infected.

Because there was no vaccination at the time of breeding, and the pigsty has always been unclean, not cleaned and not disinfected.

African swine fever occurred in 2019, and it has spread rapidly to Guangdong in the first half of 2019, and it has bloomed everywhere in Guangdong and western Guangdong. In my town at the time, African swine fever was circulating in every village committee, even in every village group.

At that time, our town was a large pig breeding town in western Guangdong, an important pig breeding base, and more than 100,000 pigs went to the Pearl River Delta region every year. Therefore, when African swine fever broke out, our town became the hardest hit area of African swine fever. Many large pig farmers, raising 1,000, 2,000, or even 5,000 pigs, are infected and killed in a large area.

African swine fever is everywhere in those small pig farms, and almost all of them are spared. At that time, almost all the main roads in the town, the roadsides of the village roads, garbage ponds, mountain sides, etc., were full of dead pigs. Even in some remote village sections, you can still see pigs infected with African swine fever, but have not died of illness for a while, driven out by farmers, running around.

At that time, whether it was a large, medium or small pig farm, once infected with African swine fever, almost all pigs would die. Of course, there is a process in which only a few pigs are infected and die at the beginning, and then slowly a dozen, dozens, or hundreds of pigs are infected and die.

However, there are very few farmers, and there are pigs in the pig farm who have non-plague, and they are waiting for all the pigs to die. Some are trying their best to treat these sick pigs with African swine fever in order to recover some of the losses; Some of them found that the pigs in the pig farm had non-plague, and immediately reported to the town animal husbandry control department, and then the relevant departments would send people to send vehicles to kill the sick pigs, and then pull the sick pigs to the treatment plant for treatment. Later, there were too many sick pigs with African swine fever, and the treatment plant could not deal with the sick pigs at all, so they took the hook machine to dig a large nest nearby and bury it.

Of course, there are also some pig farmers who do not believe in evil and refuse to bow their heads in the face of African swine fever. The pigs in their farm, even if some pigs are infected with African swine fever, they are "unhurried". That is, if a sick pig is found, a sick pig will be treated, and if two sick pigs are found, two sick pigs will be treated, and the remaining pigs that are not infected will continue to be raised.

There are two outcomes of this process. The first result is that the remaining pigs are not able to be fed, and in the end, all the pigs are infected with African swine fever and die, which is the majority of the case. This makes these pig farmers lose even more, because they also lose a lot of pig feed in the later stage, and we know that pig feed has always been so expensive.

And the second result is that the pig farmers are bo, that is, the remaining pigs are raised to the back, and some of them actually hold up and feed, which is a very small part of the situation. And once these pigs persist to the back and survive the African swine fever epidemic, it will be worth tens of thousands of gold. We know that after African swine fever, almost all pigs in many places have died, and pigs have reached twenty or thirty yuan a catty, thirty or forty yuan a catty, and a 200-kilogram pig is worth nearly 10,000 yuan.

At that time, a very small number of pig farmers survived African swine fever and made a fortune!

If you don't get vaccinated, you will. Because ASF is a viral disease, the use of antimicrobials is also ineffective, and the only way to break ASF is by vaccines and the farm's own strong biosecurity system.

I think they should all die, because they can't be allowed to enter the market.

Not all of them will die, because if you mix the words of a sick pig with a pig that is not sick, you will also develop antibodies in the pig's body over time.

The pig farm deep in the mountains is not really a paradise, and the water source cannot be too clean. Because the rivers in the motherland are crisscrossed and crisscrossed, it is impossible to distinguish each other's mother sources, and it is not known whether the rivers are polluted. In addition, the polluted river water will not only soak into the surface water underground, but also evaporate into the air, and then turn into rainwater!

It is an indisputable fact that the air in the mountains is fresh, and mosquito and fly activities are also the craziest place, but, according to the research of experts, mosquitoes and flies can quickly reproduce offspring after absorbing the blood of diseased pigs, and capture the pig farm hundreds of miles away at the fastest speed! However, people are still in the dark and do not pay much attention to the small mosquito and fly nuisance in the pig farm!

Although the epidemic has been brought under control for a short time, there are still some cases where the virus is present. For pigs in the mountains, although the pig farms deep in the mountains have little contact with the outside world, the virus will spread with the air and other materials.

In addition to close contact infection, there is another way of transmission of swine fever virus is through air circulation, so it cannot be absolutely impossible to be infected by the virus because it is in the mountains, and it can only be said that the probability of being infected is slightly lower.

Some swine fever viruses. It is also transmitted by air or other means, not that it has to be transmitted by contact.

The virus is airborne, and the air is always moving.

The virus spreads through the air and other substances.

Because the virus spreads through the air, there is also the transportation process.

The way the virus spreads is through the air.

Because the virus spreads through the air.

Because pigs get sick and it's not controlled.

Because of the raw environment may cause.

Because the living environment is more complicated.

I hadn't heard of anything like that.

Not all pigs with chronic African swine fever will die.

In general, chronic African swine fever usually has a mortality rate of less than 30%, and the mortality mainly occurs in pigs that are pregnant, young, have complications or have reduced immunity due to other reasons. In addition, the survival rate of highly virulent ASF strains may also be higher in some endemic areas due to the resistance of local pigs to the virus.

The chronic type mainly manifests progressive emaciation, anemia, weakness, sometimes mild fever, loss of appetite, constipation and diarrhea alternately, and the course of the disease is long. Mild swine fever is also chronic. Low-grade fever, atypical symptoms and lesions, low morbidity and mortality rate, some peripheral necrosis (such as the tip of the ear, the tip of the tail, and the end of the limbs**), and failure to thrive.

The course of the disease is long, generally more than half a month.

However, it will be treated prophylactically, usually with total death.

If the number of pigs is small and the density is small, the possibility of contracting non-plague is very small.

1. Probability problem. A 90 points for one step looks good, but one thing is broken down into five steps, each step is 90 points, and then the thing fails. It's a matter of probability.

It's certainly not the same when you have fewer pigs and more than you do. If you only have one pig, it's like you have only one step in one thing. You have 100 pigs, and you need 100 steps for one thing.

Can this be the case? So, there's a reason why African swine fever is easy to find on big farms, because there are more pigs.

2. Biosecurity. It is indeed inappropriate to talk about biosecurity in the absence of vaccines. In fact, without vaccines, biosecurity is a fig leaf.

But other people's good and bad are also a piece of cloth. It can also help you keep out the wind and rain. It's better than nothing.

Therefore, biosecurity is also an aspect.

3. Feeding density. Stocking density is actually a very important link in the spread of disease. The density of pigs is high, and diseases can spread easily, just like a cold.

As soon as there were too many people, the original cold was almost over, and they were infected again. If you have a small density, you can raise two pigs within 1 km. Even if one of them dies of African swine fever, maybe the other family will still be fine.

That's why some vaccines work well in the lab and are finished as soon as they get to the field.

4. The health level of pigs. The health of a herd of pigs is also crucial for the prevention of ASF. Why else is African swine fever severe in the summer, mainly due to heat stress?

If the resistance is low, the pig will naturally get sick. Then you say blue ear, ring over, why are there more pigs in the para pig and encephalitis?

Because the number of pigs is small, the possibility of contracting non-plague is very small.

It may be that they have strict defense measures in place to be able to pass through swine fever.

It should be a coincidence, that is, it happened that I was not infected with African swine fever.

The biggest reason may be that there are fewer pigs, so the probability of getting sick is relatively small.

At present, the prevention of African swine fever is still based on sealing pig farms, strengthening disinfection, and strictly controlling the flow of personnel. There are no drugs or vaccines that can control and prevent ASF.

However, we have found some preventive pig farm measures in some pig farms in Hebei, Henan and Shandong, which can be shared with you. First of all, several pig farms in Hebei, the scale is not large, the boss introduced, they have used Fuzheng Jiedu powder, some have used astragalus polysaccharides, compound anthocyanins for 4 months to about half a year, three pig farms in Nanyang, have used astragalus polysaccharides and compound anthocyanins for 3-5 months, one of which has used vitamins. If the breeding is very standardized, it is not objective, after all, the small pig farms with dozens of sows and everyone's breeding are similar.

If you say you're lucky, it's okay, but from our point of view, I still recommend that you use some nutritional additives and some traditional Chinese medicine if you can.

As far as the current information reports are concerned, once the disease is basically hopeless, there is no effective vaccine for prevention, disinfection and isolation, and maintaining a clean, ventilated and dry environment have a certain effect on preventing strokes.

Since Western medicine is not available, why not start with Chinese medicine? This is a powerful ** that China has been using for thousands of years and continues to this day, and there must be a way to deal with this plague. These two types of medicine are completely different in terms of theoretical system, thinking logic, cognitive perspective, and methods, and the historical gap cannot be compared.

Western medicine is rapidly being replaced due to the problem of drug resistance, and traditional Chinese medicine is still the same Chinese medicine that has been overcoming obstacles for thousands of years. In the history of China, there have been many plagues of all sizes, although there are also ** heavy ones, but more likely to be caused by other factors, after all, ancient times did not have the current conditions.

Chinese medicine can play a great role in the human plague, such as the SARS epidemic that broke out in 2002, Chinese medicine handed over satisfactory answers, and some doctors even submitted full marks. The plague on people can achieve such good results, but can't it be put on pigs? Definitely not, pigs can also be prevented and controlled by traditional Chinese medicine.

According to the report, the characteristics of African swine fever spreading from the north to the south, and then from the symptoms, anatomy, isolation and other data are analyzed with traditional Chinese medicine thinking: the virus is more tolerant to wind, cold, and humidity, that is, it can not be said that it is more sensitive to the thermal environment. In terms of the characteristics of rapid onset and death, the respiratory system, blood system, and digestive system of infected pigs are seriously damaged.

Is it possible to prevent it by strengthening the right and dispelling evil, replenishing the middle and invigorating the qi, and diuretic and dampness?

At present, there is no chance to confirm, I will provide you with an idea here, in case you are recruited next door to your house, you should verify it, and you can't hope for the blessing of the gods.
