Why is bovine colostrum of value to humans?

Mankind has known for thousands of years the benefit of colostrum to both newborns as well as people of all ages.

Colostrum holds many benefits for all people, but strangely enough..., It is not human colostrum that holds the greatest benefit for humans beyond the newborn stage, it is bovine or cow colostrum. This is due to a difference in the placenta of cows and humans.

The human placenta allows the passage of immunoglobulin G (IgG), which is responsible for establishing systemic immunity from mother to the fetus. This means that the human baby is born with an immune system that is already primed and ready to begin its work defending the newborn against infection.

The placenta of the cow does not allow the passage if IgG from mother to fetus. Therefore when the calf is born it is completely unprotected from infection and needs IgG from the mother's colostrum to survive.

The bovine (cow) colostrum contains predominantly IgG (over 85% of immunoglobulin) while human colostrum contain predominantly immunoglobulin A (IgA) which is designed for local immunity and is intended to the newborn's immune system to handle infections locally in the gut, rather than establish systemic immunity.

IgG, because it can pass immunity to a specific pathogen (disease causing microorganism) from one individual to another, is therefore of much more benefit to humans past stage of infancy.

Colostrum is a multifunctional complex of bioactive ingredients, produced by mammals for mammals, which means it includes humans as well.

No plant health product and or combinations thereof is so well researched, the mechanisms and the beneficial properties of colostrum for human health.

It can be said without doubt, no combination of plant-derived components could ever simulate the benefits colostrum to man and animal.
