If someone was going to do this, they should set up to do it as a small business in Texas, where wild pigs are a pestilence and essentially free for the taking.
Round up a few hundred head, selecting the best of the lot, feed them Purina Pig Chow for a couple of weeks to improve their flavor, then send them to a subcontractor abattoir.
Feeding them Purina would improve the flavor? Major fail. Salmon fed Purina taste terrrible.
