Poisonous power enhancement!The popular scope of the country is large, and the prevention and treatment of pig flow diarrhea is urgent.

As the "stubborn illness" of pig farms, epidemic diarrhea is a headache for countless pigs. Since 2010, piglets with popular diarrhea (PEDV) have swept the nationwide pig farm from north to south to give the pig farm industry.It has brought great losses, and epidemic diarrhea has also risen to one of the most harmful diseases in the pig industry in recent years.

Today, the price of piglets is not cheap. The average price of 15kg of weaned piglets has exceeded 1,800 yuan/head. Under such circumstances, less piglets make people "pain".

Popular diarrhea and infectious gastrointestinalitis are commonly known as winter diarrhea, that is, only winter occurs, especially when the coldest time before and after the Spring Festival, but now winter diarrhea has changed.There is no obvious seasonality.

In 2020, a large-scale re-production of the country, so in the end of 2020, the first nest of the nest and the second nest of the nipples. Due to the low diarrhea antibody in 1-2 fetuses, the generated antibodies were also low.Low power, the sow’s freshman piglet was threatened by diarrhea.According to incomplete statistics, current diarrhea is relatively popular in the country. Recently, the rise in piglet prices has a certain correlation with diarrhea epidemic.

At present, the popular diarrhea virus (PEDV) exists in the north and south. Whether it is a large -scale sow field, or the retail venue and the meat and pig farm, the main clinical manifestations are pregnant sow diarrhea, abortion, mammary pig diarrhea diarrhea, diarrhea, Death, and the intermittent diarrhea of fertilizer pigs!

And compared to the currently widely used vaccine on the market, PEDV has mutated and shows the phenomenon of strengthening the toxic power.

On February 25, the Ministry of Agriculture and Rural Affairs organized a video conference on the prevention and control of major animal epidemic zones in the country and the national major animal epidemic prevention and control work video conference in 2021.Animal diseases such as pathogenic avian influenza are concentrated and immune. They do not relax and do a good job of preventing and controlling FW, and guide farm households to do a good job in preventing and controlling pigment diarrhea.

Pig flow diarrhea is not a rare disease. Why do you repeatedly appear in the pig farm?

In the past two years, due to the high price of pigs, a large -scale pig farm will be introduced in the same time. If the reserve pig diarrhea is not in place, it is easy to cause low level of sow and sow’s source antibody level.Moreover, a large variable is that PEDV variants are frequent.

PEDV’s transmission pathway is difficult to control. It can be transmitted through direct or indirect contact, such as personnel, supplies, and pig indirectly in the process of selling pigs. It can also be transmitted through the form of pollution feed or air -soluble.Make sure it is not affected.

Pig flow diarrhea infection can be amplified and fixed in the pig intestines after pigs. Although the detoxification time of the intestinal tract after infection is only 2-3 weeks, the sow can take the poisoning for up to 200 days.Under stress conditions, it can be detoxified again, which has a great impact on piglets. Once the piglets are infected at 1-7 days, the mortality rate is as high as 100%.

In addition to preventing and treating repeated epidemic diarrhea, it is necessary to maintain high pressure prevention and non -work. There may be pig farmers who feel doubtful and do such strict biological safety prevention and control in preventing and wrong.Intersection

The biggest reason is that the two viruses are not the same. The FW virus cannot spread through the air through the air, but PEDV can be transmitted long -distance through gas solution!Through strict biological safety cutting measures, the transmission pathway can achieve FW prevention and control, but it is difficult to prevent PED through air -firing solution, unless air filtration.

In fact, pig farms can often only adopt air initial efficiency filtration methods to achieve air filtration. If the conditions are better, medium -efficiency filtration will be adopted.Mid -efficiency filtration cannot be 100%filtered out of the diarrhea virus.

Of course, the prevention and control of the two also has common to rely on high -level biological safety measures. The most critical of which is human biological safety awareness and biological safety measures.The difference is that PEDV has a practical and reliable vaccine. It can improve resistance through vaccine immunity and establish artificial immune lines. While sow obtaining immune protection, sow can provide piglets with the protection of female pigs to prevent pigment diarrhea.

In the face of such a situation, how should the pig farm do the prevention and control of pig flow diarrhea?Here, I give you some suggestions.

1) Strengthen biological safety management, do a good job of cutting off, strictly control multiple lines such as people, pigs, cars, things, materials, etc., and cutting off is the prerequisite for preventing and controlling diseases;

2) Raise the tires and reducing the pigs directly to introduce the sow group to reduce the harm;

3) After strengthening pig management.Reserve pigs should be isolated and domesticated for 45 days, and reserve pig vaccines must be executed in place;

4) Strengthen the management of the delivery room.The preservation of the delivery room, the first milk management of piglets must be implemented in place, and ensure the cleaning and drying of the delivery room. After the empty railings, cleaning, disinfection and drying should be strictly executed;

5) Establish an immune system for sow (including post -reserve sow) (weak poison vaccine+active vaccine);

6) Continue monitoring IgG antibodies in sow blood and IgA antibodies in colostrum. When the antibody level is low, it should be removed in time.

The above -mentioned prevention and control measures suggest that you hope to bring you some help.

Finally, to talk about it, the prevention and control of pig flow diarrhea (PEDV) is a time -consuming and twisted process. Do not ignore it. Otherwise, it is likely that some subtle operations violate the safety of biological safety, causing the PEDV virus to be activated again, resulting in abandonment before work.Essence
