Colostrum immune cells (as lymphocytes) and many antibodies such as IgA, IgG, and IgM. These are some of the components of the adaptive immune system. In preterm infants some IgA may be absorbed through the intestinal epithelium and enter the blood stream though there is very little uptake in full term babies. This is due to the early "closure" of the intestinal epithelium to large molecule uptake in humans unlike the case in cattle which continue to uptake immunoglobulin from milk shortly after birth. Other immune components of colostrum include the major components of the innate immune system, such as lactoferrin,
Conjunctive normal form formula_30 and formula_31 with a new variable, and repeating as often as necessary. To convert first-order logic to CNF: As an example, the formula saying ""Anyone who loves all animals, is in turn loved by someone"" is converted into CNF (and subsequently into clause form in the last line) as follows (highlighting replacement rule redices in formula_71): Informally, the skolem function formula_72 can be thought of as yielding the person by whom formula_60 is loved, while formula_74 yields the animal (if any) that formula_60 doesn't love. The 3rd last line from below then reads as ""formula_60 doesn't love the animal
