Pigs at this current time are only used for food and I think that is not the best they could be.
Because they are pigs and k own for being chunky why don’t they drop/make like 6.
Another thing is empty fertile soil pits/clay pits could be dug up by a pig when feed it a potato or something. It would go to nearest one then head back to pen or maybe you could lasso guide it.
Maybe along with 6 meat what about drops 2 pigs feet also which you could eat or pickle them then eat the pigs feet.
