Colostrum milk at 48 to 72 hours after parturition may be higher than in colostrum or in late-lactation milk. Fat concentration in bovine colostrum is extremely variable. Newborns have very immature and 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 is known to contain
Bilinear form form on a normed vector space is elliptic, or coercive, if there is a constant such that for all , Given a ring "R" and a right "R"-module "M" and its dual module "M", a mapping is called a bilinear form if for all , , . The mapping is known as the "natural pairing", also called the "canonical bilinear form" on . A linear map induces the bilinear form , and a linear map induces the bilinear form . Conversely, a bilinear form induces the "R"-linear maps and . Here, "M" denotes the double dual of "M". Bilinear form
