Stealing that the so-called "high fever" is rooted in immunosuppression, such as human AIDS.
Immunosuppression accumulated by various factors in the culture process:
1. Nutritional immunosuppression: Malnutrition, deficiency or excess of certain components in vitamins and trace elements can lead to impaired immune function.
2. Immunosuppression caused by poisons and toxins: Mycotoxins, heavy metals, insecticides, etc. damage the immune system, and even if the pigs do not cause symptoms of poisoning, they can make pigs susceptible to infectious diseases.
3. Infectious immunosuppression of pathogens: immunosuppression caused by swine fever, blue ear, etc.
4, drug induced immune system: such as dexamethasone, sulfonamides, tetracyclines, etc. will cause immunosuppression.
5. Immunosuppression caused by environmental stress: such as overcooling, overheating, crowding, catching, mixed groups, weaning, feed restriction, transportation, noise, and Baoding.
Therefore, the primary problem in preventing fever is to enhance the body's immunity:
1, the use of high-quality feed, adequate vitamin supplements.
2, add mycotoxin adsorbent, must not use moldy feed.
3, timely and reasonable vaccination, do not seek all over-exceeded, mycoplasma, swine fever, pseudo-mad, hooves must do, ring selected.
4. Abandon antibiotic drug health care, and change the medicines used in drug health care to immunostimulants, such as astragalus polysaccharides (non-jaundice dregs), Radix isatidis, levamisole, etc., add probiotics for a long time, compete with pathogens for binding sites, and prevent diseases. .
5, to improve the feeding environment, pay attention to health, long-term rodent control, diligent disinfection and to ensure the effectiveness of disinfection, to provide toys for pigs, to get proper exercise and maintain a comfortable mood.
For herds that have had high fever:
1, pay attention to rehydration, drinking water to add multi-dimensional, multi-mineral, brown sugar, astragalus polysaccharides and the load on the body, no odor of broad-spectrum antibiotics.
2. Diligent disinfection, use of non-irritating disinfectants for disinfection of pigs, and use of highly effective disinfectants such as peracetic acid for environmental disinfection.
3. Injection of BCG and long-acting antibiotics to enhance the phagocytic activity of macrophages, activate lymphocytes, increase cellular immunity and humoral immunity levels, induce interferon production, prevent secondary infection, and strictly prohibit multiple injections of stress.
4, feed for wheat bran porridge, stop the intake of high-copper, arsenic preparations, promote gastrointestinal motility, prevent constipation.
5, physical cooling, prevent heat stress.
