Animal Feed / Nutrition

Magnesium (Mg) is an essential mineral in all animal species diets for normal appetite, growth and reproduction. It is particularly important for bovines, horses, swine, poultry, and domesticated pets. Forage crops and grains can be deficient in this mineral, requiring a supplemental source of Mg with high bio-availability to ensure top animal performance.


Magnesium oxide (MgO) is used as a component in rumen buffers for dairy cow rations. When combined with sodium bicarbonate, MgO helps buffer the cow's rumen to improve butterfat content and help maximize milk production. Such additives are used in high energy rations for higher producing dairy cows. It also aids in the prevention of grass tetany in cattle and sheep. This condition can occur during pasture grazing. In addition, supplemental feed blocks are made with highly reactive grades of MgO to aid in the hardening process, which ensures proper block curing to prevent over-consumption by animals.


Premier's Superior Quality Magnesium Oxide

MgO and magnesium sulfate (MgSO4) are two preferred sources of Mg by nutritionists in the feed industry due to high Mg concentration and high Mg solubility, respectively. However, not all MgO sources are created equal. Due to the precision we use during the calcining process, we are able to manufacture a consistent, highly reactive and extremely bio-available product that consistently outperforms most other sources, as demonstrated by the T-50 reactivity test (pH stat), and also the Caustic Magnesia Activity (CMA) neutralization test.
