Non plague blue ear and novel coronavirus are the key to disease prevention and control

Recently, it has been reported that the situation of non epidemic prevention and control in Southwest China is becoming more and more serious.

Unfortunately, in addition to non epidemic, blue ear has become the No.

1 killer of the economic efficiency of the pig industry, and COVID-19 has become the three largest mountain on the head of pig raising enterprises.

It is suggested that the key points of biosafety should be identified in the prevention and control of non classical swine fever.

It is suggested to start with the environment.

After nearly three years of baptism of African classical swine fever, China’s pig industry has paid a huge price.

Although some enterprises have summarized many advanced experiences in practice, the current situation of prevention and control of African classical swine fever in China is still not optimistic, especially the emergence of weak strains has hit the industry twice, Recently, the southwest region was exposed to a new round of severe epidemic.

01 epidemic is always impossible to prevent.

What is the core of biosafety? The core of biosafety is people, not the procedures themselves.

Pig farm managers should focus on how to make pig farm personnel familiar with biosafety through training, set an example, implement it in strict accordance with the process, drive personnel to strictly implement biosafety procedures, and mobilize personnel’s enthusiasm and initiative.

There should be not only punishment measures, but also reward measures.

Secondly, we should understand the 28 law, find the key points in biosafety practice, and start with environmental control rather than grasping the beard and eyebrows.

Thirdly, we should implement relevant regulations for a long time and constantly improve and improve them.

We should not regard luck as ability because there is no non plague for the time being.

02 how should non plague negative field and infection field deal with non plague? For non classical swine fever negative pig farms, strict biosafety shall be provided to prevent African classical swine fever virus from spreading to the farms.

Firstly, some pig farms need to carry out biosafety transformation on the existing hardware, and then strictly implement the biosafety process.

For non plague infected fields, accurate elimination technology has been widely used and achieved good results.

However, with the emergence of natural mutants and gene deletion strains, the original tooth extraction technology is facing new challenges.

The core of accurate culling technology is to find and remove poisonous pigs at the fastest speed.

Therefore, non plague pathogen detection should be carried out for suspected cases at the first time.

Lymphatic sampling and tonsil scraping can be added in addition to the original oral and nasal sampling.

At the same time, because of the possibility of weak virus infection, we can also consider increasing antibody detection.

In addition, pig farms also need to control the environment, reduce stress factors and reduce the possibility of weak virus strains infecting pigs.

03 as the world’s leading environmental control enterprise, how does fabrick help customers prevent non-compliance? First, shortly after the outbreak of non classical swine fever in China, we invited Dr.

Louis, technical director of the French Pig Research Institute, to come to China and asked him to explain the virus characteristics of African classical swine fever and the prevention and control experience of Europe.

Second, the team translated the African classical swine fever prevention and control manual and reproduction Manual of European countries to help customers prevent and control the disease and reproduction.

Third, Fabrik’s technical team helped the pig farm to improve biosafety equipment and launched an easy and safe energy-saving pig house and warm, wet and clean panoramic intelligent environmental control unit to provide pigs with a healthy and comfortable growth environment throughout the year, ensure biosafety and eliminate stress reactions.

An Yijie positive pressure heat insulation pig transport vehicle was also launched to ensure the biological safety of logistics links and reduce stress response.

At present, we are also developing biosafety app, which can help customers conduct professional biosafety audit after going online.

The immune effect of blue ear vaccine is not ideal.

In prevention and control, we should pay attention to the “three three system principle”.

China’s “feed prohibition” has caused “stress” to the aquaculture industry to a certain extent.

At the third international veterinary testing and diagnosis conference held in the middle of the year, some experts pointed out that blue ear and diarrhea are still the most serious diseases in pigs at this stage; The risk of outbreak and epidemic of foot-and-mouth disease in non immune pig farms is high.

Some experts pointed out that blue ear is one of the most serious diseases in pigs.

What do you think? In addition to non plague, blue ear disease is still the biggest problem in pig farms.

It has a very prominent impact on sows and nursing pigs.

Sows are prone to abortion.

Nursing pigs will have a high incidence of bacterial secondary infection due to immunosuppression, such as Haemophilus parasuis, Streptococcus, mycoplasma, etc., which will lead to a high proportion of death when severe.

During the resumption of production, many pig farms introduced from multiple points, which also caused the rapid spread of blue ear disease of different strains.

Blue ear virus has rapid mutation, diverse strains and easy recombination.

Although vaccine immunization has a certain effect on blue ear disease, from the feedback of farmers, the effect of vaccine immunization is far from ideal.

Some pig farms try to purify blue ear disease.

However, in addition to the high cost, how to maintain negative for a long time is the biggest problem.

05 how to prevent and control blue ear disease? Epidemic control is a systematic project.

A few years ago, we put forward the “three three system principle” for the prevention and control of blue ear disease, which is to do a good job in three aspects: first, do a good job in vaccine immunization, select a vaccine whose safety is not easy to return to strong virulence, and formulate scientific immunization procedures; Second, select high-quality drugs, such as temicaocin combined with other drugs, which can not only control bacterial secondary infection, but also reduce the replication speed and inflammatory response of blue ear virus; Third, control the temperature, humidity and density, implement fine feeding management, and do a good job in isolation and adaptation of reserve sows, pig flow management, stress management, etc.

These three aspects complement each other and must be done well at the same time in order to maintain the long-term stability of blue ear disease positive pig farms.

Prevention is greater than treatment.

The best doctor is to prevent disease, and the best management is to keep the pig farm from getting sick, rather than being proficient in the treatment of pig disease.

Therefore, we should master the principle and practice of biosafety and prevent trouble in the first place.

Fabrik was founded in 1973.

Crown group in Denmark successfully solved the problem of uneven temperature, humidity and air outlet speed in the slaughtering workshop, improved pork quality and ensured food safety.

In the 1980s, he began to set foot in animal husbandry and launched a new environmental control model to ensure biosafety.

It entered the Americas in the late 1980s and Asia in the 21st century, and increasingly expanded its customer base from food industry to medicine, tobacco, automobile, cold storage, supermarkets, exhibitions, sports venues and other industries, becoming a leading enterprise in global environmental control.

Based on the concept of environmental protection, Fabrik has been involved in the fields of renewable and clean energy such as air energy, water energy, light energy and ground energy since the beginning of this century.

Its customers are in more than 90 countries and regions, and there are more than 10000 practitioners around the world.

It entered the Chinese market in 2006, and its business performance was very bright.

It served most of the top 20 pig raising enterprises in China and was highly praised.
