Not all colostrum is created equal, and understanding its quality can influence how well calves get started. That’s why having the right tools to measure colostrum quality can help producers make better feeding decisions for newborn calves.
Immunoglobulin (IgG) levels in colostrum can vary widely, from less than 20 mg/mL to more than 100 mg/mL depending on factors like the cow’s breed, health history, season and how much colostrum she produces. In general, colostrum with at least 50 mg/mL of IgG is considered high quality and provides the antibodies calves need for a strong start.
