Does anyone change their piggy diet during the winter months? Adding different veggies to give them a little extra? I don't know if this is the correct way to put it, but my pigs and I are moving to a different state, and it gets really cold during winter and even though we will have a space heater I'd like to plan their diet if it needs some change. I currently feed 1 or 2 leaves of lettuce, 1 grape tomato, 1/8 of bell pepper, 1 baby carrot and a small pidce of butternut squash.per pig per day.
