Feral pigs are mostly domesticated pigs that got loose. They breed with other wild pigs which commonly have the russian bloodline. Some more prominent than others. They have evolved a bit to adapt to the wild. The nose is longer being that they rely on rooting more so than domesticated pigs. Taste wise, they are delicious. I have not tried the javelina, but have heard the taste was somewhat "wild". Feral pigs will destroy a coastal field because they like to eat the soft, sweet roots. They will also turnover a pecan orchard for the nuts. There diet also includes anything deer will eat. The reason people sour the corn is a). raccoons and other small animals dont like it as much soured, therefore saving on bait cost. Another thing people do is put diesel fuel on the corn. Pigs are drawn to diesel because if ingested, it helps fend off parasites. 2). Feral pigs have an amazing sense of smell. By souring the corn, you can bring them in from long distances. A feral pig can detect a potato buried in the ground for more than 100 yards away. Feral pigs can be trapped with a cage equipped with a guilotine door or a swing door. simply set a trip wire towards the back, pig trips wire, doors slams closed. You can either transfer the trapped pigs to a holding pen for fattening or to sell, or shoot (to be more specific, KILL) the pig, take it out of the trap and eat it. Most people quarter the pig up and soak in ice water for a few days to drain out all the blood. Once the liquid from the cooler comes out clear, its time to eat it. Meat taste great.I prefer to smoke it. I would put it up against a nice rib-eye any day.
