Colostrum is the first form of milk produced by mammals, including humans, immediately after giving birth. It is thick, yellowish, and rich in nutrients, antibodies, and growth factors. This special milk is crucial for newborns as it helps boost their immune system and provides essential nutrients for growth and development. Colostrum is produced in small amounts during the first few days postpartum before transitioning to regular milk. It contains high levels of immunoglobulins, which are proteins that help protect the baby from infections. Consuming colostrum can significantly impact a newborn's health and well-being in their early life.
