Bovine colostrum is the first ever food for newborn calves, produced by mothers before secreting maternal milk.

Colostrum composition itself makes it radically different from normal milk, because colostrum’s role is to confer to the recipient a wide spectrum of substances that are essential for development and for protection from pathogens that the newborn may encounter. Colostrum typically contains a set of immunoglobulins (IgG, IgM and IgA), lactoferrin, PRP (Prolin-Rich Peptides, which are stimulants of immune system), vitamins, minerals and many other compounds. Most substances are active inter-specifically, so bovine colostrum is particularly beneficial for humans too.

Several references of colostrum are available, characterized by different concentrations of total proteins and Immunoglobulins, and pre-formulated versions too, ready for the market.
