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 form, it follows that, for all , It also follows that is a fixed point of the map . The fixed points of this map from a subgroup of the additive group of . A -Hermitian form is reflexive, and every reflexive -sesquilinear form is -Hermitian for some . In the special case that is the identity map (i.e., ), is commutative, is a bilinear form and . Then for the bilinear form is called "symmetric", and for is called "skew-symmetric". Let be the three dimensional vector space over the finite field , where is a prime power. With respect
