Yeast Selenium Feed Additive: A Natural & Efficient Organic Solution for Farmed Animals Health
Selenium is essential for livestock health, supporting antioxidant defense, immunity, and reproduction. However, traditional inorganic selenium (e.g., sodium selenite) has low bioavailability, high toxicity, and poor absorption. Yeast selenium feed additive, an organic alternative, combines safety and efficiency, upgrading selenium supplementation in animal husbandry.
Product Introduction
Yeast selenium is produced by fermenting Saccharomyces cerevisiae or Candida utilis in selenium-rich media. Yeast cells absorb inorganic selenium and convert it into easily utilized organic forms (mainly selenomethionine and selenocysteine). Unlike inorganic selenium, it integrates into yeast protein, making it safer, more stable, and suitable for poultry, livestock, and aquatic breeding.
Content Specification
Yeast selenium content is formulated for different animals, with common feed-grade specs of 1000mg/kg, 2000mg/kg, or 3000mg/kg (organic selenium ≥98%). Optimized fermentation can reach 2846μg/g dry yeast. Recommended additions: 0.3-0.6mg/kg DM for dairy buffaloes, 0.3mg/kg for young Rex rabbits, 1.5mg/kg for laying hens.
Product Characteristics
Compared with inorganic selenium, yeast selenium has distinct advantages: high bioavailability (2.9x that of sodium selenite in ruminants), safety (no poisoning risk or environmental residue), good stability (heat-resistant during processing), and dual nutrition (providing yeast protein and B vitamins).
Product Functions
Yeast selenium boosts livestock breeding efficiency and product quality: it enhances antioxidant capacity (increasing GSH-Px, reducing MDA), strengthens immunity (promoting lymphocyte proliferation), improves production performance (higher egg/milk yield, weight gain), optimizes product quality (selenium-enriched products, better meat color), and protects liver/reproductive health.
With demand for high-quality livestock products rising, yeast selenium is a top choice for breeders. Its advantages protect animal health, improve product quality, and support efficient, sustainable husbandry.
