Eucommia Ulmoides粉末

Mechanism of action of Eucommia bark powder in feed

1. Antibacterial and immune regulation

Active ingredients: flavonoids (quercetin, kaempferol), iridoids (geniposide).

Function:

Inhibit harmful intestinal bacteria (such as Escherichia coli and Salmonella) and promote the proliferation of probiotics.

Enhance animal nonspecific immunity (such as macrophage activity and lymphocyte proliferation).

2. Improve intestinal health

Polysaccharides and dietary fiber:

Soluble fiber promotes intestinal peristalsis and absorbs toxins.

Polysaccharides, as prebiotics, stimulate the growth of lactic acid bacteria and bifidobacteria.

3. Promote growth and feed conversion rate

Eucommia gum and amino acids:

The viscosity of Eucommia gum can delay gastric emptying and prolong feed digestion time.

Natural amino acids (such as γ-aminobutyric acid) regulate nerve function and reduce stress response.

4. Replace antibiotics

Green farming trend:

Reduce drug resistance and drug residues caused by antibiotic abuse.

Synergistic effects of natural ingredients (such as flavonoids + polysaccharides) replace some antibiotic functions.

Typical application formula

1. Livestock and poultry feed additives

Chicken feed formula:

Eucommia bark powder 3-5% + lactic acid bacteria 0.1% + vitamin E 0.02%

Effect: Reduce feed-to-meat ratio by 5-8%, improve egg yolk color and chicken antioxidant level.

Pig feed formula:

Eucommia bark powder 2-4% + Bacillus subtilis 0.05% + Astragalus polysaccharide 1%

Effect: Improve the gloss of pig fur and reduce the incidence of diarrhea.

2. Aquatic feed additives

Aquatic formula:

Eucommia bark powder 2-3% + algae extract 1% + mineral premix

Effect: Enhance the fish's ability to resist stress (such as transportation, water change) and reduce mortality.

3. Ruminants (cattle, sheep)

Formula:

Eucommia bark powder 1-2% + rumen buffer (such as baking soda)

Effect: Relieve rumen acidosis and promote crude fiber digestion.

Processing technology optimization

1. Pretreatment process

Fermentation treatment:

Mix Eucommia bark powder with probiotics (such as lactic acid bacteria) and ferment for 3-5 days to decompose cellulose and improve the utilization rate of effective ingredients.

Advantages: Reduce lignin content and improve palatability.

Enzymatic modification:

Use cellulase and xylanase to release more polysaccharides and flavonoid aglycones.

2. Compounding and synergistic technology

Combined with probiotics:

Eucommia bark powder + Bifidobacterium → Synergistically regulate the balance of intestinal flora.

Compounding with Chinese herbal medicine:

Eucommia bark powder + Astragalus + Honeysuckle → Enhance antiviral and anti-stress effects.

3. Microencapsulation

Process: Encapsulate Eucommia bark powder in gelatin or starch capsules.

Advantages: Mask bitterness, prevent gastric acid damage, and accurately release to the intestines.

Practical application cases

1. Egg chicken farming

Experimental design: Add 3% Eucommia bark powder vs control group (no addition).

Results:

Egg production rate increased by 6.2%, and egg breakage rate decreased by 3.5%;

Cholesterol content in egg yolk decreased by 12%, and polyunsaturated fatty acids (DHA/EPA) increased by 8%.

2. Pig fattening

Experimental design: basic diet + 2% Eucommia bark powder.

Results:

Daily weight gain increased by 4.7%, and feed-to-meat ratio decreased by 5.1%;

Liver detoxification enzyme activity increased, reducing the use of antibiotics.

3. Shrimp farming

Experimental design: Add 2.5% Eucommia bark powder to feed.

Results:

Shrimp survival rate increased by 15%, and resistance to white spot syndrome virus (WSSV) was significantly enhanced;

Glutathione peroxidase (GPx) activity in muscle increased by 20%.
