African swine fever has made farmers panic, and it has occurred in many places. It is urgent to do a good job in biosecurity and prevention and control. However, there is no effective vaccine and drug control in the world. Many farmers know that biosecurity and regular addition to improve the resistance of livestock are effective measures to reduce the occurrence of diseases. Astragalus polysaccharides are currently the most used.

Astragalus polysaccharide is actually the main active ingredient of Astragalus. It can be used as an immune booster or regulator. It has anti-viral, anti-tumor, anti-oxidant, anti-radiation and anti-stress, enhances body resistance, promotes immunity, promotes antibody synthesis, and two-way Regulate blood sugar and protect the cardiovascular system.

Now, astragalus polysaccharides are used as immune enhancers and antiviral drugs in pig production, which effectively improves the disease resistance and production performance of the pig herd。

一．Prevention and treatment of swine viral diseases

1. Astragalus polysaccharide can induce animal body to produce interferon, regulate body's immune function, and promote antibody formation.Adding astragalus polysaccharides to the basal diet can increase the content of various cytokines to varying degrees, and significantly improve the body's ability to resist viral diseases。
2、In the prevention and control of swine virus diseases, Astragalus polysaccharides can increase the feed intake of pigs, promote the recovery of infected pigs, improve the health of the body, and reduce the incidence.

3、When pig farms are threatened by viral diseases, such as foot-and-mouth disease, circovirus disease, influenza, swine fever and other viral diseases, Suggestion: Use astragalus polysaccharide and amoxicillin in combination to reduce the occurrence of diseases, and promote rapid recovery of diseases in pig farms that have already suffered from epidemics.
4、Use before and after vaccine immunization can increase the level of antibodies, relieve the stimulation of the vaccine to the body, and reduce the occurrence of adverse vaccine reactions.

二、Prevention and treatment of pig bacterial diseases

In the prevention and treatment of pig bacterial diseases, Astragalus polysaccharide can not only promote the immune function of the immune system of suckling piglets and weaned piglets, and enhance the disease resistance of pigs.Reduce the incidence of "three diarrhea (red, yellow, white diarrhea)" in suckling piglets and diarrhea of weaned piglets, increase survival rate, promote growth and development, increase weight gain speed, and reduce feeding costs.

When piglets have yellow and white scour and epidemic diarrhea, it is recommended to use astragalus polysaccharides, colistin sulfate and oral rehydration salts, which have a good effect on preventing diarrhea and dehydration.
