These pigs are supposed to be around 15 pounds. We were told to feed them 1/4 cup of pig feed a day but we didn't think that was enough so we started feeding them more. We feed them 1/4 cup in the morning and 1/4 cup in the evening (and snacks in between). As with any pig, they will eat whatever you give to them, but they are much happier if you do not let them get too big. People who have never seen this breed of pig think that you are being cruel and not feeding the pig properly to keep it small. That is not so. We have overfed our pigs and they get fat but they do not get 'Big'. I think that 30 pounds is very fat for this breed.
