Feed grade magnesium oxide is a free flowing, calcined natural magnesite manufactured from quality deposits characterized by high magnesium content. This material plays an important role in animal diets by promoting normal appetites, growth and reproduction. Magnesium oxide also plays an important role in the prevention of grass tetany. Magnesium is a highly potent macromineral in bone tissue, nervous system and digestive system as it enters into the structure of many enzymes in the body. Has a positive effect on meat and milk production as well as on claw and reproductive health.
Magnesium deficiency in cattle and sheep can lead to a condition called grass tetany. This condition is more common in the spring and fall when levels of magnesium in the natural forage are not adequate to maintain healthy levels within the animal. Feed supplements and mineral premixes are commonly used to provide the necessary levels of magnesium to the animals to prevent grass tetany. MgO is the most widely used source of magnesium for these applications.(feed grade)
MgO is also an important source of magnesium for rumen buffers and dairy supplements. It offers an available source of magnesium, which aids in increasing lactational performance.
Calcined Magnesite is used as a refractory agent in the construction of crucibles. A crucible is a container which is intended to be placed in extremely high temperatures for the sake of heating its contents. Since the crucible itself must not be affected by the heat, it must be made with substances which retain their properties at high heat. Magnesium oxide is such a substance, so it is used in this manner.(technical grade)
Due to these same heat-resistant properties, magnesium oxide powder makes an excellent insulator. It is used as the mineral component of mineral-insulated copper-clad cables, a form of industrial cable used for the protection of particularly critical electrical circuits during a fire, including fire protection devices such as alarms or smoke control systems
