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
Quadratic form is also called a quadratic form. Two "n"-dimensional quadratic spaces and are isometric if there exists an invertible linear transformation (isometry) such that The isometry classes of "n"-dimensional quadratic spaces over "K" correspond to the equivalence classes of "n"-ary quadratic forms over "K". Let "R" be a commutative ring, "M" be an "R"-module and be an "R"-bilinear form. A mapping is the "associated quadratic form" of "b", and is the "polar form" of "Q". Alternatively, a quadratic form may be characterized as follows: Two elements "v" and "w" of "V" are called orthogonal if . The kernel of a bilinear
