Fubon Selenium yeast, produced by submerged fermenting Saccharomyces cerevisiae in a selenium-rich media, is a recognized source of organic form selenium nutrient for animals.


  • Improve animal reproductive performance
  • Relieve stress
  • Reduce somatic cell counts in milk
  • Improve carcass quality

Mode of Action

Improve Selenium Deposition and Availability
The selenomethionine in selenium enriched yeast is actively absorbed from the small intestine and travels in the blood by amino acid transport mechanisms. Mammals are not able to distinguish classic methionine form from selenomethionine, which is thus it can either be transported to the liver for incorporation into selenoproteins or directly to other tissues for incorporation into tissue protein. On the contrary, the sodium selenite is passively absorbed by the small gut, and before converting to selenoproteins, it has to release harmful radicals and convert into selenide. And this process is energy-wasting. Inorganic selenium surplus is excreted through the urine rather than stored in the tissues.

Improve Immunity, Relieve Stress
Selenium plays an important role in the effective operation of immune system. It can directly or indirectly improve the animal immune response. Selenium deficiency may affect the proliferation of T and B lymphocytes, and further reduce the production of immunoglobulins, such as IgM, IgG and IgA.

Improve Anti-Oxidant Capacity and Carcass Quality
Selenium acts as a component of the main antioxidant cellular enzyme, glutathione peroxidase (GSH-Px), which destroys the peroxides and protects the cell content and sub-cellular membranes of oxidative damage. Organic selenium supplementation can significantly increase serum GSH-Px activity and total antioxidant capacity decrease the serum malondialdehyde (MDA) content. And effectively prevent myoglobin or oxygenation myoglobin into ferric oxide myoglobin, deepen muscle red degree and improve the color grading.

Guaranteed Analysis

Total selenium content ≥ 2000mg/kg; Organic selenium > 98%
