Selenium is added to feeds because the levels of this nutrient are low and variable in most parts of the country. Cows need selenium for defense against diseases, to produce healthy calves, and to maintain optimum fertility.

Sel-Plex is an organically bound, similar to a plant form of Selenium that is more bio-available to the cow and also allows for tissue reserve Another benefit of having organic selenium within the animal feed is the more efficient use of dietary vitamin E.

There are benefits for the calf as well, such as higher milk and colostrum Se, and improved antioxidant status; this gives the calf stronger resistance to disease and improved resistance to cold stress at birth...

   Independent research indicates other benefits may include:

• Fewer days between calving
• Less services per conception
• Improved fertility
• Fewer Se-related calving problems (i.e.,retained placenta) associated with tissue integrity
• Better disease resistance (i.e., against mastitis)
• Lower somatic cell counts · Higher thyroxin levels
