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
Mammal tooth pairs of molars and between three or two premolars. For example, the tiger quoll ("Dasyurus maculatus") is a dasyurid marsupial native to Australia. The quoll possesses four upper incisors and three lower incisors per left and right-hand side [I = 14]. Along with two upper premolars [PM] and two lower premolars per side [PM = 8] and four upper and four lower molars per side [M = 16], giving the animal a complement of thirty-eight teeth. The Tiger quoll's dental formula is as follows: Rabbits and other lagomorphs usually shed their deciduous teeth before (or very shortly after) their birth,
