Porkpal, I guess I should have been a bit more specific...........we have many more dairy operations around here; but the guys that have beef usually put them out on the stalks after the corn is harvested. There would not be enough good quality feed out there (and too much corn if your combine did a cruddy job...........LOL) for a dairy cow to produce milk. The very BASIC nutritional needs would probably be met, but a dairy cow requires more specialized nutrition for milk production. Not to mention that beef cows are tougher. LOL
