how a cow produces milk

Plant material will soften in the first chamber. The second chamber has microorganisms that feed on the softened plant material. This makes energy and proteins.

In the third chamber material will move through into the small intestine as nutrients and extra water are put back into the the bloodstream.

Next it circulates to the mammary gland in the udder. Milk is created when cells combine the nutrients with sugars from the cow's liver. Then her udder will fill with milk so she can feed her calf or get milked by a dairy farmer.
