West virginia dnr says hogs there (which is more northern part of hog range) have 3 to 5 total piglets per year. Not the muliple litters and higher numbers of the south.

Wv treats their hogs in southern counties as a valued resource, and has been trying to allow its hog numbers to increase for some time now, but it isnt happening, even with limited hunting opportunities.

Black bear, coyote and bobcat all REALLY work on the piglets.
