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
Genus of a quadratic form so in this case all genera contain the same number of classes of forms. Genus of a quadratic form In mathematics, the genus is a classification of quadratic forms and lattices over the ring of integers. An integral quadratic form is a quadratic form on Z, or equivalently a free Z-module of finite rank. Two such forms are in the same "genus" if they are equivalent over the local rings Z for each prime "p" and also equivalent over R. Equivalent forms are in the same genus, but the converse does not hold. For example, "x" + 82"y" and 2"x"
