How to introduce sow farms during non plague periods? What should I pay attention to when introducin

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.

Since the outbreak of African swine fever in China, it has had a great impact on China's pig industry, and pork ** once soared to 30 yuan catty.

Once a pig in a pig farm is infected with African swine fever, it can affect the whole farm in a short period of time, bringing huge economic losses to pig farmers.

At present, the African swine fever epidemic has been controlled to a certain extent, and the state has begun to encourage pig farmers to raise pigs.

1. African swine fever review.

Pig farmers should carefully review all the factors for African swine fever to enter the pig farm, and do not let go of any details.

After enumerating it, we will study the feasible measures one by one, and strictly implement them to prevent further problems.

Pig farmers should not only strictly screen for problems in their own farms, but also understand the causes of African swine fever in other farms and self-examine to avoid making the same mistakes.

2. Pig farm disinfection management.

African swine fever is an acute, highly contagious infectious disease that spreads mainly through direct contact between pigs, people and organisms, and objects.

Therefore, if you want to recuperate, the pig farm must do a good job in the purification of African swine fever and block the way of African swine fever into the pig farm, that is, to do a good job in the biosecurity of the pig farm, and the most direct embodiment of the biosecurity of the pig farm is disinfection.

Before the pig farm is rehabilitated, it is necessary to carry out strict cleaning and disinfection of the pig farm inside and outside for many times, and it is necessary to choose a highly effective disinfectant with strong killing effect on African swine fever.

The disinfection procedure is first soaked with disinfectant, then rinsed, then soaked with foam disinfectant, then rinsed, or with a flamethrower for high-temperature disinfection.

In addition, it is necessary to disinfect the drinking water source of pigs to prevent African swine fever from remaining in drinking water.

3. Pig farm rehabilitation assessment.

1. Regularly sample multiple areas of the production area and living area, and carry out African swine fever antigen detection, once every two weeks, more than 3 consecutive tests, and each antigen test is negative to achieve the conditions for rehabilitation.

2. Select a certain number of 3-5 months old fattening pigs for rehabilitation experiments, and raise them for 42 days (the longest incubation period of African swine fever) The health of the pig herd continues to be stable, and the pig farm meets the conditions for rehabilitation.

3. There has been no African swine fever epidemic in the region for more than 3 months.

4. The pig farm lifted the blockade of the African swine fever epidemic for more than 3 months, and there was no new epidemic.

5. There is no African swine fever epidemic around the pig farm.

The fatality rate of African swine fever is 100%, and the loss caused to pig farms can be said to be devastating.

The above conditions must be met before the pig farm can be rehabilitated.
