Is there a limit to how much apple waste I can feed my pigs? We have two little porkers, about 4 months each (bought at auction, not sure of exact age). We currently feed them a mix of corn, day-old sub buns from Subway, my food scraps from in the kitchen, and occasional left-overs from a caterer friend. Today I was offered basically all the apple peels and apple chunks I could possibly ever use, from an orchard. I understand excessive feeding of apples can cause gas and/or diarhea; is this correct? In which case, what is a reasonable amount? We would be mixing it with the other food items.
