A live yeast culture derived from the specific yeast strain Saccharomyces cerevisiae increases fiber, phosphorus and calcium digestibility in mares, and increases digestible energy, total lipids and amino acid absorption improves milk availability to foals if administered for 3-4 weeks before and throughout the lactation period. Organic Selenium – selenium is an essential nutrient that plays a critical role in metabolism, healthy growth, reproductive health, and immunity. It also acts as a powerful antioxidant to prevent fatty acid oxidation which can cause tissue damage. Research has shown that Sel-Plex, an organic form of selenium, is more readily absorbed and retained than selenium in inorganic forms. Sel-Plex is the only organic selenium to be reviewed by the FDA. Bio-available Trace Minerals, or chelated minerals, are those that have been bonded to two or more amino acids. A mineral in this chelated state allows easy passage through the intestinal wall into the blood resulting in increased metabolism of that mineral. dac Orange Superior utilizes organic minerals to increase availability and enhance absorption rates.
