Years ago I watched Dickey Betts of The Allman Brothers http://popup.lala.com/popup/432627047850146622hunt
with his traditional bow on a Florida citrus farm where feral pigs were dining on oranges, perhaps just the ones that had fallen and fermented, but they were surely there in full force like clock work, every evening showing up to dine.
I have fed pigs acorns before, they love them! I raised two feral Hampshires I caught in the wild for roughly 8 weeks until they were moved to a 13 acre farm where they grew and grew and grew. The male was Cool Breeze, the female Little Girl. I fell in love with these pigs and didn't have the mindset to eat them when their new owners slaughtered them.
I would fill Cool Breeze's feeding trough up with acorns and he would eat them until he would pass out on his side and continued eating with his eyes closed! I'm not making this up, talk about comical! Pigs love acorns!
