Selenium Yeast Feed Grade

CAS Number: 7488-56-4

Selenium Yeast is an organic selenium source produced by cultivating Saccharomyces cerevisiae in selenium-enriched medium, predominantly incorporating selenium as selenomethionine with superior bioavailability compared to inorganic sodium selenite or selenate. It supports antioxidant defence via glutathione peroxidase, thyroid hormone metabolism, immune function, and reproductive performance. Our product is standardised at 1000–2000 ppm organic selenium.

heavy metals (ppm)≤10
loss on drying (%)≤8.0
total selenium (ppm)≥1000
organic selenium (ppm)≥1000

Applications

  • Poultry and swine premium premixes as the high-bioavailability selenium source
  • Breeding animal feeds to improve fertility and hatchability outcomes
  • Dairy cow selenium supplementation to reduce white muscle disease
  • Aquafeed to increase selenium tissue deposition in edible fish
  • Selenium-enriched egg and meat production programmes

Key Features

  • Selenomethionine-rich organic form with 1.5–2x bioavailability over inorganic Se
  • Serves as a body selenium reservoir improving long-term selenium status
  • Lower risk of selenium toxicosis versus inorganic selenite at equal supplementation
  • Improves selenium transfer to eggs and muscle tissue for enriched product claims
