How to treat repeated fever in pigs effectively

Many pig farmers often encounter this problem during pig farming: the pigs they raise frequently have repeated fever or persistent high fever, and no matter what medicine is used, it cannot be cured, which makes people very anxious. So what causes repeated fever in pigs? How should it be treated? Let's take a look together.

1. Why do pigs have repeated fever

This may be caused by a relatively poor growth environment for the pigs, inadequate feeding management, insufficient drinking water causing constipation, or poor resistance, all of which can cause fever. In addition, many diseases can also show symptoms of fever, such as swine influenza, swine fever, porcine reproductive and respiratory syndrome, swine respiratory diseases, swine pasteurellosis, etc. Because many pig farmers do not understand their symptoms, they often treat them as ordinary wind-heat colds, but they are not treating the root cause at all, so repeated fever often occurs. In addition, in summer, when the temperature is high and hot, poor heat dissipation from the pig's body can also cause fever.

2. Clinical symptoms

Generally, mild fever manifests as dry feces or constipation, while severe fever may cause symptoms such as skin bleeding, redness of the ears, rapid breathing or coughing, loss of appetite, and listlessness. If such symptoms appear and are not treated in time, they may endanger the pig's life.

3. Prevention and control measures

For the phenomenon of repeated fever in pigs, in order to reduce the degree of dry feces and constipation, the first step is to supply clean drinking water all day, and electrolytes or water-soluble vitamins can be added to supplement nutrition. At the same time, adjust the feed formula to achieve a balance of various nutrients, reduce stocking density, and give the pigs sufficient space for activity, which is also beneficial for heat dissipation from the pig's body and helps reduce the degree of fever.

4. Treatment plan

Fever in pigs can be divided into two types: physiological fever and pathological fever. Physiological fever is caused by toxins accumulating in the pig's body. When the toxins in its body accumulate to a certain level, they affect the central nervous system and cause a disorder of the body temperature regulation system, so the body temperature naturally rises. An oral rehydration salt method can be used, generally about 25 grams per pig per day, which not only clears heat, benefits the gallbladder, relieves constipation, and reduces symptoms, but also strengthens the stomach and promotes appetite; astragalus polysaccharide injection and ceftiofur can also be injected, for three days. Pathological fever is caused by viral and bacterial infections. Viruses and bacteria multiply in large numbers in the pig's body, and the immune system responds. White blood cells and phagocytes fight the viruses and bacteria and generate heat. For this type, treatment must be targeted according to the specific disease the pig has, so that it can be effectively prevented and controlled.
