Each spoon contains a minimum of 3,970 mg/max 4,540 mg of calcium, a minimum of 1,700 mg of phosphorus, a minimum of 19.5 mg of copper, a minimum of 80 mg of zinc, a minimum of 80 mg of manganese, a minimum of 0.21 mg of selenium, a minimum of 0.68 mg of iodine, a minimum of 210 mg of lysine and vitamins A, D and E. Indications: You can feed on fortified or unfortified grains. Fortified grains contain added vitamins and minerals and require a lower feed rate of this supplement. If you eat unfortified grains †“Foals 3-12 months - 2 oz daily; Cravings for up to 2 years - 3 oz daily. Consult an equine nutritionist or DAC if you eat fortified grains. Spoons included. 60-day money-back guarantee. What makes Dac Colt Grower different? Yea Sacc1026 †“a living yeast culture derived from the specific yeast strain Saccharomyces cerevisiae 1026. Yea Sacc1026 increases the digestibility of fiber, phosphorus and calcium, and increases crude energy, total lipids and amino acid absorption. Yea Sacc1026 improves the availability of milk to foals if administered for 3-4 weeks before and throughout the lactation period. Amino acids in young horses lysine is considered the first limiting amino acid and is the most important factor affecting growth. Methionine, another essential amino acid, is also important for the proper growth and development of muscle tissue in young foals. 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 the oxidation of fatty acids that can cause tissue damage. Research has shown that Sel-Plex, an organic form of selenium, is easier to absorb and retain than selenium in inorganic forms. Sel-Plex
