Magnesium in Dairy Ration Buffers

Buffers in dairy rations are compounds that neutralize excess acid within the animal s digestive system. The increased emphasis on production and efficiency in dairy cows has lead to an increased use of high concentrate or high-energy rations. Since these rations have more easily fermentable starch in them, this results in increased acid production in the rumen and subsequent acidosis. Higher acidity can result in reduced feed intake, lower milk production, and decreased butterfat. It can also endanger the animal s health and cause liver abscesses, fatty liver syndrome, rumenitis, and laminitis. 

Buffering the ration with sodium bicarbonate can help reduce the effects of excess acidity. However, tests have demonstrated that feeding a combination of magnesium oxide and sodium bicarbonate can help maintain a
