| Selenium interacts with vitamin E. It acts in conjunction with glutathione peroxidase, an enzyme that deactivates peroxides. In regions where the soil contains little selenium, pasture alone can often not ensure sufficient selenium supply. Selenium should be supplemented, but the overall limit of 2 mg selenium / kg of feed dry substance must not be exceeded (see also EQUISTRO SUPER "E"). Magnesium is necessary for the activation of many enzymes - also in the muscle metabolism - and it is involved in the protein, fat and carbohydrate metabolism. Adult horses require between 10 and 13 g Mg per animal and day, foals between 5 and 10 g. Since only free-grazing horses can usually be assumed to get sufficient amounts of magnesium, supplementation is indicated in winter. In cases of sub-normal intake and utilization of magnesium or when bodily reserves are quickly depleted under severe mental and physical stress, horses react with stress symptoms such as inappetence, exhaustion, poor condition, excitability, nervousness and sweating. Lysine is the single most important building-block in the muscle synthesis of growing foals, weanlings and remounts in training. The maintenance requirement is at least 23g lysine per animal and day. In mares during pregnancy and lactation, the requirement increases to 50 g per animal and day, and the same applies to growing horses and working 2-year-olds. Trials have shown that the supplementation of 40 g lysine per day in foals significantly improved their weight increase and muscle formation - measured in the m. longissimus dorsi - in comparison to animals with lower lysine supplement levels. Equistro Excell E is thus particularly suited for horses in training and competition. Equistro Excell E assists in relieving muscle tenseness, improves rideability and can help increase muscle power and stamina. Other uses for Equistro Excell E include initial care of healthy, but especially of sickly, foals.
