Problems solved by technology

It is mainly manifested in the situation that the breeding conditions are constantly improving, but the production level has not been improved accordingly. The biggest problem is the high incidence of epidemic diseases, and the main reason for the high incidence of epidemic diseases is immunosuppression, which affects the immune effect of vaccines and makes the clinical The major epidemic diseases of pigs are difficult to control, and even a vicious circle has appeared, which seriously restricts the production of the pig industry.
[0003] At present, there is no good method and means to eliminate or alleviate pig immunosuppression

Abstract

The invention discloses a compound relieving immunosuppression of pigs and the application of the compound. The compound comprises astragalus polysaccharide, epimedium extract, glossy privet fruit extract, fructus psoraleae extract, bicarb, butafosfan and Victim B12. When the compound serves as a feed additive and is added to feed and applied to immunosuppression of the pigs, the immunosuppression of the pigs can be effectively relieved, and disease resistance performance of the pigs and vaccine immune effect can be improved.

Description

technical field [0001] The invention relates to a compound for alleviating immunosuppression of pigs and application thereof, belonging to the field of veterinary medicine. Background technique [0002] With the rapid development of my country's pig industry in terms of breed improvement, breeding scale, nutritional level, disease health care prevention and control, and pig specialization, it is also facing great confusion. It is mainly manifested in the situation that the breeding conditions are constantly improving, but the production level has not been improved accordingly. The biggest problem is the high incidence of epidemic diseases, and the main reason for the high incidence of epidemic diseases is immunosuppression, which affects the immune effect of vaccines and makes the clinical The major epidemic diseases of pigs are difficult to control, and even a vicious circle has appeared, which seriously restricts the production of pig industry. [0003] At present, there ...
