Astragalus polysaccharide (APS)

Astragalus polysaccharide (APS) is an active ingredient extracted from the root of natural Chinese herb Astragalus by Vland Biotech through a special production process. It can help control virus and promote immunity of animals.


1. Reduce the risks of diseases caused by immunosuppression in poultry, livestock and aquaculture;
2. Enhance animals immunity by strengthening non-specific and specific immunity, promoting both cellular and humoral immunity, consolidating the phagocytic function of immune cells and increasing the level of interferons and other immune factors;
3. Offer a synergy when used with vaccines to reduce immune responses and increase antibody titer;
4. Improve digestibility and reduce FCR.


1. Extracted from Chinese medical herbs, APS is of no residue, no drug resistance, no incompatibility and no negative effect on the effectiveness of vaccines during immunization.
2. APS has a unique mechanism of action.
After intake, APS will: a) mobilize animals immunocytes and phagocytes within a very short time to improve their immunity, b) quickly participate in humoral immunity and stimulate the body to produce antibodies against the virus, and c) reduce respiratory and intestinal immune responses after immunization and protect animals during the immunity gap period.


C(APS) ≥ 450 mg per gram of the product.
