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 of a complex Hermitian form is a Hermitian matrix. A complex Hermitian form applied to a single vector is always real. One can show that a complex sesquilinear form is Hermitian iff the associated quadratic form is real for all . A complex skew-Hermitian form (also called an antisymmetric sesquilinear form), is a complex sesquilinear form such that Every complex skew-Hermitian form can be written as times a Hermitian form. The matrix representation of a complex skew-Hermitian form is a skew-Hermitian matrix. A complex skew-Hermitian form applied to a single vector is always pure imaginary.
