They even get wise to traps. We have caught up to a dozen at a time in the right trap. Not all big ones.
I'm not sure I've ever eaten a large boar. Young boars are OK.
But never ever try to dress one that has been eating peanuts (they like to destroy peanut patches). If they eat a heavy diet of peanuts they are so greasy they are worthless. You cannot get it off your hands.
Most feral hogs are pretty lean. If they are not confined they are less apt to have diseases. We've made some great sausage from them. At times we pinned them and fed them a while before we butchered them. Some of them required adding a little fat to make them sausage cook properly.
We have a meat house at the farm. With commercial equipment and walk-in box. We never do it commercially, but have dressed a lot of game for family and friends. It takes several knowledgeable bodies to do it generally.
And we have a big pit type smoker that we make the best beef sausage ever made. 100 year old recipe.
So greasy they are worthless? I’d think lard city.
Boar meat is edible, it just smells bad when cooking, like a wet dog. I’ve shot feral hogs, and just cook them on the grill, since one piece of boar meat will ruin the kitchen.
