Porcine immunosuppressive disease
The immune system is the pig body's defense forces, is the pig body's favorable weapon against disease. But when the immune system is abnormal, the immune function will decline, leading to a variety of diseases. Immunosuppression is a manifestation of abnormal immune function in animals. It refers to a pathological phenomenon that the immune system of pigs is damaged due to various reasons, the ability of the pig body to resist a variety of pathogens is significantly reduced, and pigs are vulnerable to the invasion of pathogenic microorganisms and lead to secondary infection or mixed infection.
Some immunosuppressive factors are inevitable, such as group transfer, refuelling, weaning, environmental stress and other normal feeding and management work will cause immunosuppression, but as long as we take scientific and reasonable ways to deal with it, we can minimize the harm of immunosuppressive diseases; However, most of the time, because of the subclinical symptoms of porcine immunosuppressive disease (especially viral and bacterial pathogens), it is often ignored by the breeding personnel, which leads to the growth of pigs with virus, and then slow development or death. The serious loss makes the breeding people unprepared!
Therefore, improving immunity is the fundamental to solve the problem! Among them, non-specific immunity is the first line of defense against pathogenic microorganism infection. It has a wide range of immunity, which is not specific to specific antigens. It can react to foreign bodies both inside and outside the pig body, and plays an extremely important role in the body's defense mechanism.
