A cow has to give birth to a calf every year to keep milk production going. By nature, a cow cannot produce so much milk that it has been enforced by breeding animals on a perfect body for one purpose: producing an extremely high amount of milk. A meat and blood milking machine that needs to be replaced after a few years because it's worn out.
