Product Details
Yeast Culture (Selenium-Enriched) is a composite strain product built primarily on selenium-enriched yeast, developed with fermentation metabolism as its core process target. Through carefully screened composite strains that cooperate and interact throughout the fermentation process, the product generates over a thousand metabolic by-products, resulting in a functional fermented ingredient rich in organic selenium components and diverse bioactive metabolites.
The composite strains exhibit strong fermentation adaptability and tolerance, enabling the biological conversion of inorganic selenium in the fermentation substrate into an organic selenium source that is more readily absorbed and utilized by animals. The product undergoes a low-temperature drying process at the final stage, maximizing the retention of high levels of active substances — including organic acids, amino acids, vitamins, and mannan-oligosaccharides.
Organic Selenium — generated through biological conversion by composite strains, offering higher bioavailability and lower toxicity risk than inorganic selenium sources.
Mannan-oligosaccharides — typical value ~5.6%, supporting gut health and balanced intestinal microbiota.
Complex organic acid system — lactic, malic, and citric acid (total organic acids ~9.09%), helping regulate digestive tract pH and inhibit harmful bacteria.
Glutathione — ~2.02 mg/g, working synergistically with organic selenium to enhance antioxidant function.
Free amino acids and B-vitamin complex — supporting readily absorbable nutrition and overall metabolic function.

The values above are typical analysis values. Actual test results may vary slightly by batch; please refer to the factory test report for specific figures.
Swine Production: Suitable for breeding sow/boar diets to support reproductive performance, and finishing pig diets to improve meat quality.
Poultry Production: Suitable for breeder layer/broiler diets to improve hatching egg quality, and commercial layer diets for functional egg product development.
Ruminants (Cattle & Sheep): Suitable for lactating cow/ewe diets to improve milk quality, and breeding sires to support reproductive performance.
Aquaculture: Used in broodstock development and grow-out diets to improve stress resistance and reproductive performance.
Organic selenium bio-conversion with higher bioavailability
Complex bioactive component system — organic acids, amino acids, vitamins, mannan, and over a thousand metabolites
Low-temperature drying process preserving active substances
Three clearly defined benefits: antioxidant/immune support, meat and milk quality, reproductive performance
Universal across species — swine, poultry, ruminants, and aquaculture
Specific inclusion rates should be determined under the guidance of a professional feed nutritionist, based on species, growth stage, reproductive status, and overall diet formulation. Especially recommended for: breeding-stage diets, milk quality improvement during lactation, functional animal product development, and periods of elevated oxidative stress or immune pressure.
Q1: What's the difference between Yeast Culture (Selenium-Enriched) and standard yeast culture?
Standard yeast culture primarily provides nutritional metabolites, while the selenium-enriched version additionally enriches organic selenium through biological conversion — delivering both nutritional supply and selenium fortification.
Q2: What are the advantages of organic selenium over inorganic selenium sources such as sodium selenite?
Organic selenium generally offers higher bioavailability and greater safety, making it better suited for long-term, stable selenium supplementation.
Q3: Is the product suitable for all species at all growth stages?
The product is broadly applicable across species, but inclusion rates should be adjusted based on species, growth stage, and reproductive status. Consult a professional feed nutritionist for tailored recommendations.
