The Colostrum Counsel – Improving The Quality Of Maternal Colostrum Through Supplementation With A Colostrum Replacer
February 2025
Colostrum, rich in nutrients and antibodies, is essential for providing passive immunity to newborn calves. The concentration of Immunoglobulin G (IgG) in colostrum is a key factor in determining its quality, and Brix refractometry is commonly used on farms as an indirect measure of IgG concentration in colostrum. Feeding calves with high-quality colostrum during the first hours of life is crucial for ensuring adequate IgG transfer, as calves strictly rely on it to develop disease resistance.
