No would be the correct answer here, and for good reason. If you're a veterinarian or other type of animal scientist (or a rancher for god's sake), please stop reading now. I don't want to embarrass myself.
This doesn't mean that ruminants can survive on moldy hay and prarie dust, though. They ideally need good hay that has appropriate protein and crude fiber content (yes, even though it's a weird idea to wrap your head around, grass does have a protein content). So we feed them hay in the morning, they meander over to the water tank for a drink, come back to the hay ground and lay around in the uneaten warm forage and regurgitate their food. This ruminant digestive system requires that they masticate all of the forage that they've consumed by bringing it back in to their mouth and chewing, sometimes several times over, in order to allow the latter of the two stomach components to properly absorb all of the nutrients. It's called chewing their cud and they don't do it just because they're bored. It's just what the little evolutionary bug told them to do.
