Home Feeds Ingredients Magnesium Oxide Calcined Magnesite

Calcined Magnesite - Feed Ingredient

Calcined magnesite is produced by thermally processing naturally occurring magnesite ore to form a refined, high-magnesium oxide material. It is available in forms such as fine powders or granules, with its characteristic composition and consistent quality retained through the calcination process.

In equine nutrition, calcined magnesite is incorporated as a mineral ingredient to adjust the overall magnesium content in feed formulations. It is typically blended into vitamin-mineral premixes or directly added to concentrate feeds, contributing to a balanced mineral profile in diets formulated for performance horses, growing foals, and lactating mares.

The following equine feeds, supplements and products contain Calcined Magnesite as an ingredient.
