The "law of unintended consequences" kind of screams on this one, not a good idea. Red Tail Hawks, Turkey Buzzard and others are threatened now. Chowing down on a poison carcasses is unlikely to help them any.
Users of Kaput Feral Hog Lure are required to dispose of the carcasses. We will see how that one works out.
Kaput is a hog killing system complete with special feeders:

The Australians used Warfarin to kill wild hogs but concluded it was inhumane and outlawed its use. They now use sodium nitrite. Sodium nitrite kills faster.
Actually shooting hogs from helicopters is very effective but rather seldom used by state agencies or farmers/ranchers. A local game here warden killed 74 hogs in one flight.
The USDA has been shooting wild hogs (and coyotes) from the air for many years. Two weeks ago USDA were shooting hogs from helicopters in the Wichita Mountains Wildlife Refuge.
Well meaning hunters and landowners are adding to the hog problem by running deer feeders. Nearly every unfenced deer feeder attracts hogs. Yep, i was guilty of feeding and raising wild hogs for years. Then i wised up: You can either effectively trap wild hogs or feed wild hogs, can't do both. Now my feeders are fenced and hogs very seldom get to the corn.
BTW: India wiped out their buzzards with a veterinary medication. There were widespread consequences.
Drought does a trick on wild hogs. We were in severe drought here from 2010 until 2015. i saw hundreds of dead hogs during the drought. In a few south western Oklahoma counties the hog population has not recovered from that drought. Used to see sounders of 80-120 wild hogs on the wheat fields there, now hogs are scarce.
