Farmers and ranchers often feed the cows. However cows are able to feed themselves when they're out grazing on pasture.
Grass is the most inexpensive feed you can feed your cows. It grows in your backyard and in your pastures, and only requires the cows to harvest it themselves. Hay comes as the second least expensive feed to feed cattle.
Depends on how hungry and malnourished they are. If some cows broke into a feed house where grain was stored and they gorged themselves on the grain, they could very much die of bloat and/or acute acidosis.
