On a related topic: Years ago, I read up on Water Buffalo production.
My recollection is that the dairy breeds of water buffalo produce a lot
less milk than a dairy cow, but that the solids (fat and protein) were
much higher -- enough higher that simple dilution with water would yield
comparable "milk" volume and solids composition to that from one of our
standard western dairy cows. I'm not suggesting dilution of anybody's
milk, but it struck me that much of our intensive dairy cow breeding over
the past decades has mostly allowed the cows to put through more
water. Do any Sanetters have a more informed perspective on this?
