Sodium Selenite Feed Grade
CAS Number: 10102-18-8
Sodium Selenite is an inorganic selenium compound used as the standard cost-effective selenium supplement in animal feeds, essential for glutathione peroxidase activity, thyroid hormone synthesis, and immune function. It is the most widely permitted form of selenium supplementation globally and is used in premixes at strictly controlled inclusion rates due to the narrow margin between deficiency and toxicity. Our feed-grade product is precision-diluted for safe premix use.
