It's not that they revert, it's that the care and feeding is a part of this. Most hogs grow tusks, but they are docked or trimmed in some fashion. All pigs, even the "classic" pink cute ones you might think of when you think farm pig are covered in coarse "fur" though it is not as thick as you find on a feral hog like a razorback or some other such thing. Source; was a farmer. Edit: also, I didn't even think about this when I first wrote this, but we also butcher hogs VERY young, so they haven't had time to develop those "wild" traits yet by the time they are market size. So that might be part of it, too.
