Magnesium Oxide - Feed Ingredient
Magnesium Oxide is an inorganic compound composed of magnesium and oxygen. It is typically produced through the calcination of magnesite (magnesium carbonate) or by processing magnesium hydroxide derived from seawater. As a fine, white powder, Magnesium Oxide is valued for its high concentration of magnesium and stability under a range of conditions.
In equine diets, Magnesium Oxide serves as a supplemental source of magnesium, an essential mineral that supports muscle function, nerve conduction, and bone integrity. It is commonly included in feed formulations or supplements to help horses meet their daily magnesium requirements, especially when forages or other dietary components do not supply adequate levels. The bioavailability of Magnesium Oxide can vary depending on factors such as particle size and overall diet composition.
The following equine feeds, supplements and products contain Magnesium Oxide as an ingredient.
