Cows do not eat corn in their natuaral diet. They eat grass. Cows are being fed corn because it is cheap and plentiful. Because corn is not a natural food for cows, they need help digesting it and are fed antibiotics to keep their digestion healthy.
Cows and goats need to be fed on grass and oilseed cakes because grass and oilseed cakes are milk producing food so these help them to produce milk
