High-concentration MgO is a vital component in livestock feed, widely recognised for its effectiveness in promoting growth performance, enhancing metabolic stability, and supporting immune function. Due to its high elemental magnesium content, low moisture sensitivity, and superior thermal and chemical stability, MgO is especially suited for use in ruminant and monogastric nutrition systems. As a slow-release, bioavailable mineral source, it contributes to nutrient homeostasis and long-term mineral sufficiency in intensive production environments.

In ruminant diets, high-purity MgO functions as a key ruminal buffer. Its alkaline properties help stabilise rumen pH, particularly under high-concentrate feeding regimes, thereby reducing the risk of subclinical acidosis. Research involving feedlot cattle has demonstrated that MgO supplementation increases ruminal pH and decreases systemic stress indicators such as plasma haptoglobin and cortisol, markers associated with improved welfare and digestive stability. Additionally, MgO contributes to bone mineralization by assisting calcium and phosphorus balance during rapid skeletal development, especially in growing and lactating animals.

In monogastric animals such as poultry and swine, the inclusion of high-concentration MgO in mineral premixes supports efficient feed conversion and immune robustness. It activates magnesium-dependent enzymes, such as superoxide dismutase and glutamine synthetase, which are crucial in reducing oxidative stress and improving nutrient absorption. A targeted feeding trial in poultry demonstrated improved feed efficiency and enhanced growth uniformity with MgO inclusion, attributed to its stable magnesium delivery and compatibility with premix formulations.

Altogether, high-purity MgO presents a scientifically validated and operationally efficient solution for addressing magnesium demands in modern livestock feeding systems. Its integration into compound feeds or premixes ensures consistent mineral supplementation, optimized animal growth trajectories, and reinforced physiological resilience—cementing its role as a cornerstone mineral additive in intensive animal agriculture.
