The organic selenium has a high availability when compared to inorganic forms. Both ruminants and non-ruminants can absorb organic Se easily, but inorganic Se can't be absorbed by ruminants in selenide form.
The protein content and quality in animal feeds can influence the uptake of dietary Se and its bioavailability.
Se yeast provides Se in an organic form like selenomethionine and selenocystine.
Se yeast is readily assimilated by animals, provides the needed protection against degradative cell processes and enhances the immunocompetence of your animals Protective effects on the liver and other tissues
Prevent oxidative damage of the cell membrane and subsequent
Premature aging of the cell
Prevent diseases as muscular dystrophy, pancreatic fibrosis, ventriculus myopathy, exudative diathesis and others.

Product Description:
The discovery that Se is an integral component of glutathione peroxidase was made by Rotruck et al (1973). The selenium, as an essential part of GSH-Px, reduces already formed hydro peroxides to less reactive alcohols (Pehrson, 1992).
The GSH-Px catalyses the reduction of lipid peroxides before they can attack cellular membranes. The enzyme is capable of reducing different peroxides generated within a biological system by using the reducing equivalents derived from the reduced form of glutathione according to the following general equation (Combs and Combs 1984):
ROOH + 2 GSHàROH + H2O + GS-SG.
The most important biological activity of selenium is through the enzyme glutathione peroxidase, which, in co-operation with vitamin E and several other antioxidative agents, is capable of reducing the destructive effects on living cells of peroxidative reactions.
