Astragalus Polysaccharide Extract

1.Product Details

2. Core Functions

2.1 Immune Enhancement (Core Function)

Stimulates the proliferation and activation of animal lymphocytes, macrophages, and natural killer cells, enhancing the body’s non-specific and specific immunity.

Promotes the secretion of cytokines (interleukin – 2, interferon) in animals, improving the immune response to vaccines and reducing the risk of vaccine failure.

Strengthens the immune barrier of young animals (piglets, chicks, fry) and improves their resistance to maternal antibodies.

2.2 Anti-Stress & Disease Resistance

Alleviates stress responses in animals caused by transportation, feed conversion, environmental changes (temperature, humidity), and vaccination.

Enhances the body’s antioxidant capacity by increasing the activity of superoxide dismutase (SOD) and glutathione peroxidase, reducing oxidative damage to animal cells.

Assists in the prevention and adjuvant treatment of viral and bacterial infections (e.g., avian influenza, swine fever, aquatic aeromonas infections) by boosting immune function.

2.3 Growth Promotion & Production Performance Improvement

Improves the digestibility and absorption of nutrients (protein, vitamins, minerals) in feed, increasing daily weight gain of livestock and poultry.

Enhances the laying rate of laying hens, improves eggshell quality, and reduces the mortality rate of broilers.

Promotes the growth of aquatic animals (fish, shrimp), increases survival rate, and improves feed conversion ratio (FCR).

For dairy cows, it can improve milk yield and milk quality, reducing the incidence of mastitis.

3. Clinical Test Results

The clinical tests were conducted by an authoritative veterinary research institute, covering 5,000+ animals of different species. The key results are as follows:

3.1 Poultry Test (Broilers & Laying Hens)

Test Object: 1,200 1-day-old broilers; 800 20-week-old laying hens

Test Method: Add 30% APS to the basic feed for 42 consecutive days

Results: Broiler daily weight gain increased by 12 – 15%; feed conversion ratio decreased by 8 – 10%; mortality rate reduced by 25 – 30%. Laying hens’ laying rate increased by 5 – 8%; broken egg rate decreased by 18 – 22%.

3.2 Aquatic Animal Test (Tilapia & Shrimp)

Test Object: 2,000 3cm tilapia fry; 1,000 juvenile white shrimp

Test Method: Mix 30% APS into feed for 60 consecutive days

Results: Tilapia weight gain increased by 18 – 20%; survival rate reached 92% (vs. 78% in the control group). Shrimp survival rate increased by 22 – 25%; resistance to hypoxia and ammonia nitrogen stress was significantly enhanced.

3.3 Dairy Cow Test

Test Object: 50 lactating dairy cows (mid-lactation period)

Test Method: Add 30% APS to the total mixed ration (TMR) for 30 consecutive days

Results: Daily milk yield increased by 3 – 5kg per cow; milk protein content increased by 0.15 – 0.2%

Recommended Dosage

Special Notes on Usage

Dissolve the powder in water first for uniform mixing if using in wet feed or drinking water (dosage: 100 – 200g per 1000L drinking water).

It can be used in combination with probiotics, vitamins, and non-antibiotic feed additives without antagonistic effects.

For animals in severe stress or recovery period, dosage can be increased by 20% under veterinary guidance.
