It is vital that calves receive colostrum (first milk) from their mothers for passive transfer of immunity. Colostrum is rich in antibodies, also known as immunoglobulins, that protect the young calf from disease until its immune system begins to function. A well managed colostrum feeding program is an important factor in the health of newborn calves. The PortaCheck IgGCheck passive transfer test is a rapid on-farm tool for the qualitative determination of immunoglobulin G (IgG) concentration in whole blood. Calves that have an IgG level over 1,000 mg/dL are healthier, considered to have successful passive transfer, and are more likely to survive.
