Question

Cows eat grass and give milk

Answer 1

The process whereby cows and other ruminants digest and assimilate grass and leaves is long and complex. The workings of a cow’s alimentary canal is much more involved and complicated than your stomach and intestines. The “green” in grass is mainly chlorophyll, which is very quickly broken up, along with the cellulose structure of the grass. Fats, minerals, polypeptides, amino acids, sugars, and a vast number of trace elements are absorbed along the length of the cow’s intestine, circulated in blood and other fluids, metabolized in the liver and used or stored throughout the carcass.Milk contains no chlorophyll (so no green color) but is an emulsion and a solution of fats, protein, and minerals in water, giving a white appearance, although during certain seasons, if the animal is feeding on fresh lush grass, the cream and especially the butter can take on a slightly more golden hue, as a result of the beta carotene from the grass.
