Colostrum is high in carbohydrates, protein, and antibodies and low in fat (as human newborns may find fat difficult to digest). Newborns have very small digestive systems, and colostrum delivers its nutrients in a very concentrated low-volume form. It has a mild laxative effect, encouraging the passing of the baby's first stool, which is called meconium. This clears excess bilirubin, a waste product of dead red blood cells which is produced in large quantities at birth due to blood volume reduction, from the infant's body and helps prevent jaundice. Colostrum contains all five immunoglobulins found in all mammals, IgA, IgD, IgE, IgG and IgM. There are many beneficial proteins in the colostrum, including a variety of growth factors (IGfs).
