Healthy and stable pigs are the basis of normal production and good economic benefits. In the current swine herd, immunosuppressive diseases are widespread, and the resistance of swine herds is low and secondary infections are serious. It is important and urgent to strengthen the management of winter health care in pig herds.

The focus of winter pig care is good environment
Good environment factors including temperature, humidity, air quality, health and farms in the surrounding environment, these factors on the importance of pig farms should be more and more big, gradually improve the quality of living environment of pigs, to maximize the potential growth of pigs, reduce the incidence of opportunities. The important thing is the temperature and ventilation.
temperature
Warmth is a very important environmental condition. Winter is cold and warm, the temperature control part of the current domestic pig has been doing very well, such as air conditioning, heating and winter using stable electric heating plate, an infrared lamp has a good effect; the winter temperature is too low will cause the main herd resistance drops, not through wind, often leads to high mortality of respiratory disease of pigs. Increased.
aeration
Ventilation is an important measure to ensure air quality and reduce the concentration and humidity of harmful gases. At present, effectively solve the problem of ventilation, temperature ventilation automation pig to simple mechanical ventilation is very rare, but also a small part of the pig farm, so the hardware improvement is still a long way to go. The problem of temperature and ventilation can not be effectively solved, so it is very difficult to raise a pig. Air quality and bad temperature often leads to herd resistance severely reduced, slightly wind sways grass (Ying Ji) will lead to the pathogenesis of swine.

　　The difficulty of winter health care for swine herds is the elimination of immunosuppression

　　Blue ear virus, circovirus and mycotoxin can cause immunosuppression and reduce the resistance of pigs. The susceptibility to various secondary pathogenic microorganisms has increased, causing morbidity and mortality in pigs to remain high. It can be said that immunosuppression is one of the most important factors that cause the disease, the control effect is not ideal and the level of production is difficult to improve. Therefore, how to reduce the immune suppression of pigs and improve the resistance of pigs is an important issue that must be taken into consideration by our pig breeders. PRRS PMWS are currently no vaccine for swine is effective application, so we must take strict prevention, strengthen management, reduce stress and other comprehensive measures to reduce the harm of these diseases, but also need to add Aodeman immune enhancer A, so that the pig's resistance will be significantly enhanced, decreasing morbidity and mortality. Have a good effect on foot and mouth disease, high fever, Circovirus Disease and other bacterial diseases; control of mycotoxins should start from the source, strict control of raw materials procurement, procurement of raw materials of good quality, is the fundamental strategy.

　　The core of winter herd health is nutrition

　　Now the research of feed nutrition change rapidly, nutrition has not only meet the nutritional needs of pigs, but also make full use of the advanced research results, from a nutritional point to improve the non-specific immunity of swine herds, enhance the anti stress ability, is the core of the herd health. The Chinese medicine medicine as tonic, to pigs, but also has great reference significance. Scientific use of 135 health care pig technology, strengthen the pig disease resistance nutrition, enhance immunity, improve production results.　　
 

The key stage of pig health in winter is breeding pigs
Multiple pig disease in the delivery room and nursery pigs, it is rooted in the pig, so do the herd for health care, improve the health level of the breeding herd, take care measures only from the source to prevent the emergence of the disease.
Introduction quarantine and good introduction
Before the introduction, we must establish the awareness of antigen detection. We must check the antigens of some important diseases, such as PRRS, circovirus, swine fever, pseudorabies and so on, so as to prevent the introduction of these diseases into the field.
Strictly quarantine and properly domesticate
Due to the introduction of replacement pig borne pathogens and pathogens inside travel there are certain differences. Therefore the introduction of the pig to isolation, isolation time to reach more than 3 months, then in the polyculture before domestication, to adapt to each other to make the introduction of the field of pig and pig, produce immunity. The specific method is: in the isolation period, the main diseases of the reserved pigs are immune, and the field sows out or protects the diseased and recovering pigs for a week, so that the resistance of the imported pigs is improved. Some people introduced pigs to big pigs, but there was not enough quarantine time to tame them. In a hurry to do some immunization began to breed, resulting in the first fetal sow stillbirth, high proportion of mummies, the loss outweighs the gain.

　All the work is based herd health to fully mobilize the enthusiasm of the staff inside are employees, only to fully mobilize their work enthusiasm and initiative, the work to do, all kinds of rules and regulations to implement fine management, in order to truly fine. The working environment of the pig farm is closed and difficult, and the staff are mostly away from their families. The managers should earnestly care for the employees and take the people as the basis, and the employees will take the field as their home. Therefore, even better hardware facilities, scientific health care procedures, but also the need for workers to put it in place.
