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
Bilinear form form on a normed vector space is elliptic, or coercive, if there is a constant such that for all , Given a ring "R" and a right "R"-module "M" and its dual module "M", a mapping is called a bilinear form if for all , , . The mapping is known as the "natural pairing", also called the "canonical bilinear form" on . A linear map induces the bilinear form , and a linear map induces the bilinear form . Conversely, a bilinear form induces the "R"-linear maps and . Here, "M" denotes the double dual of "M". Bilinear form
