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
Milk shark known parasite of this species is the copepod "Pseudopandarus australis". There is some evidence that male and female milk sharks segregate from each other. Like other requiem sharks, the milk shark is viviparous; females usually have a single functional ovary (on the left) and two functional uteruses divided into separate compartments for each embryo. The details of its life history vary across different parts of its range. Females generally produce young every year, though some give birth every other year or even every third year. Mating and parturition take place in spring or early summer (April to July) off western
