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
Invariant of a binary form or decimics. "Quantic" is an old name for a form of arbitrary degree. Forms in 1, 2, 3, 4, ... variables are called unary, binary, ternary, quaternary, ... forms. A form "f" is itself a covariant of degree 1 and order "n". The discriminant of a form is an invariant. The resultant of two forms is a simultaneous invariant of them. The Hessian covariant of a form is the determinant of the Hessian matrix It is a covariant of order 2"n"− 4 and degree 2. The catalecticant is an invariant of degree "n"/2+1 of a binary form of even degree
