We used to raise 2 - 4 hogs every year. We decided to take a couple years off. I like eating pigs but I don't like raising them. They stink. I much prefer cattle. This year we're growing corn, squash and watermelon in the pig pen.
I do mob grazing (aka Management Intensive Grazing) and move the cows and goats about every other day (breaks the worm cycle too), and the hogs now, about every 3-4 days. Keeps down on the manure build up and is less "stink." Give them enough room, they organize themselves with a poop section, separate from their A-frame and where the root up.
