Most feral pigs are nasty (as opposed to wild hog which is good). Feral pigs also carry a lot of parasites. In some areas of East Texas, they have gotten so bad, we have hunting parties out on people’s farms but we just leave the ones we shoot for the buzzards.
Here in CA, we’ve had feral hogs ever since the Spanish came. Then in the 1920s someone introduced wild Russian boar to hunt on their ranch near Big Sur. Now pretty much all the hogs are hybrids, which are very tough, disease resistant and tasty. Best of both worlds, as it were. IIRC, the feral pigs have 36 chromosones, the Russian boar have 38, and the hybrids have 37. They can all interbreed.
I had wild boar’s ribs at the rodeo BBQ cookoff one year and those were some of the most delicious, succulent ribs I’ve ever had. I couldn’t stop eating them.
