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
Sesquilinear form basis of , a sesquilinear form is represented by a matrix , by the column vector , and by the column vector : The components of are given by . A complex Hermitian form (also called a symmetric sesquilinear form), is a sesquilinear form such that The standard Hermitian form on is given (again, using the "physics" convention of linearity in the second and conjugate linearity in the first variable) by More generally, the inner product on any complex Hilbert space is a Hermitian form. A vector space with a Hermitian form is called a Hermitian space. The matrix representation
