One of the most significant physiologic responses that occurs at calving, is that a high percentage of calcium crosses from the bloodstream into the udder. The result is a significant drop in blood calcium levels putting cows at risk of milk fever (hypocalcemia or low blood calcium).
Subclinical hypocalcemia can result in many health challenges that greatly reduce productivity of the early lactation dairy cow—and makes her more susceptible to infectious disease. However, it is possible to formulate rations for close-up dry cows, by using a DCAD diet, which can reduce the incidence of subclinical hypocalcemia, resulting in a healthier and more productive cow in early lactation.
A negative DCAD ration (acidic diet) stimulates the physiologic process of calcium resorption from the bones. University studies show that a high-quality negative DCAD ration for close-up dry cows can support the following:
• Increased dry matter intake
• Increased milk production
• Decreased disease risk
• Decreased uterine infections and retained placentas
• Decreased displaced abomasum
• Decreased udder edema in first calf heifers
• Improved reproductive performance
Our new AminoMax DCAD product has an excellent negative DCAD value, palatability, and contains a high bypass methionine amino acid profile. Following rigorous lab testing, this product is currently under final field evaluation on commercial dairy operations.
