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
Invariant of a binary form the form itself of degree 1 and order 1. The algebra of invariants of the quadratic form "ax" + 2"bxy" + "cy" is a polynomial algebra in 1 variable generated by the discriminant "b" − "ac" of degree 2. The algebra of covariants is a polynomial algebra in 2 variables generated by the discriminant together with the form "f" itself (of degree 1 and order 2). The algebra of invariants of the cubic form "ax" + 3"bx""y" + 3"cxy" + "dy" is a polynomial algebra in 1 variable generated by the discriminant "D" = 3"b""c" + 6"abcd" − 4"b""d" −
