Colostrum Colostrum Colostrum (known colloquially as beestings, bisnings or first milk) is the first form of milk produced by the mammary glands of mammals (including many humans) immediately following delivery of the newborn. Most species will generate colostrum just prior to giving birth. Colostrum contains antibodies to protect the newborn against disease. In general, protein concentration in colostrum is substantially higher than in milk. Fat concentration is substantially higher in colostrum than in milk in some species, e.g. sheep and horses, but lower in colostrum than in milk in some other species, e.g. camels and humans. In swine, fat concentration of
Sesquilinear form to is Similarly, is orthogonal to with respect to , written (or simply if can be inferred from the context), when . This relation need not be symmetric, i.e. does not imply (but see "" below). A sesquilinear form is reflexive if, for all , That is, a sesquilinear form is reflexive precisely when the derived orthogonality relation is symmetric. A -sesquilinear form is called -Hermitian if there exists such that, for all , If , the form is called -"Hermitian", and if , it is called -"anti-Hermitian". (When is implied, respectively simply "Hermitian" or "anti-Hermitian".) For a nonzero -Hermitian
