I gave my pigs mostly starter at first/ then grower/cracked corn mix. Finisher I give about a month before butcher. Grower is plenty also by itself. Lots of fresh water. I did give some sweet grain sometimes but just a bit in with other feed once in a while. I gave hay little handful or 2 every other day. Also gave bread/milk they loved it it was there favorite. I got a cart of day old bread for $3 and gave slop to them all the time. Love yogurt too buy it old when on sale and freeze it. Fruits/veggies. Some veggies they can't have, no meat or chocolate either. I have gave wheat but soak it the night before in hot water it expands. Contact your local feed mills and ask for screenings. I get cheap pea screenings, wheat screenings etc to feed. Sometimes you can get cheap feed from, food bank, restaurants, and farmers that is going bad.
