is a form of milk produced by the female breast in late pregnancy and the first few days of delivery containing antibodies essential to protect the newborn against diseases, Due to the new-borns rather small and immature digestive systems, nutrients within the colostrum are delivered in a very concentrated low-volume form. It also has a mild laxative effect, encouraging the passage of the baby's first stool also known as meconium. This helps to clear the excess bilirubin, a waste-product of dead red blood cells, produced in large quantities at birth due to blood volume reduction, from the infant's body and thus preventing jaundice a condition caused by accumulation of bilirubin. The most pertinent bioactive components in colostrum are growth factors and antimicrobial factors. The antibodies in colostrum provide passive immunity, while growth factors stimulate the development of the gut. They are passed to the neonate and provide the first protection against germs.
