Feed-grade magnesium oxide is typically a white, odorless powder with a fine texture. Its chemical formula is MgO, with a molecular weight of 40.30 and a relative density of 3.58. It has a high melting point, generally around 2800°C. Additionally, it is an alkaline compound that is soluble in acids but insoluble in ethanol. In the air, feed-grade magnesium oxide can absorb carbon dioxide and water to form magnesium hydroxide.

Magnesium is a component of various enzymes in livestock and poultry. It plays a crucial role in the normal growth and development of skin, fur, and bones, reproductive functions, the development of the taste system, and the normal functioning of the cardiovascular system. Magnesium is also essential for maintaining fur growth, skin health, and tissue repair. It influences the synthesis of DNA and RNA and is involved in the metabolism of nucleic acids and proteins.

Feed-grade magnesium oxide plays an important role in livestock and poultry feed. It can promote growth, increase body weight and muscle mass, and improve meat quality. It also helps regulate the acid-base balance in livestock and poultry, preventing acidosis and alkalosis. Additionally, feed-grade magnesium oxide can enhance the resistance of livestock and poultry, improving their disease resistance and reducing the occurrence of diseases. It also promotes digestion and absorption, increasing feed utilization and reducing feed waste. For poultry, feed-grade magnesium oxide can act as a gastrointestinal regulator, improving digestive function. For dairy cows, it can increase milk yield and quality. For aquatic animals, it effectively promotes growth and improves meat quality.

Feed-grade magnesium oxide can also improve the hygiene of livestock and poultry housing by reducing the production of harmful gases such as ammonia and hydrogen sulfide.

In summary, feed-grade magnesium oxide plays a significant role in livestock and poultry feed. It not only provides essential nutrients but also improves the health and growth performance of livestock and poultry.
