Do sheep eat apples?

[desperance]

Or - put it the other way - has anyone ever milked a pig?

All I'm saying is that sheep's cheese and apples go together - specifically, in a sheep's-cheese-and-apple-butter* sammich on sourdough, fried in butter - remarkably well. Pork and apple is famous, but mutton and apple not so much; which is why I wonder whether the affinity is internal. Saltmarsh lamb, again famous. Maybe by extension sheep eat apples and hence the flavinoids find their way into the milk...?

But coming back to my second question, has anyone ever milked a pig? And if not, why not? Is pig's milk just too difficult to obtain, or not digestible, or what?
