Pigs will eat anything! We raised them years ago and always fed ours hog feed but they will eat anything you throw at them, no matter how rotten. The smellier the better. LOL
The proper term here in Texas is we "slop" the hogs....usually a bucket of scraps...
A hungry hog will eat anything...I've seen ours eat live chickens that were dumb enough to venture into the pens.....feathers and all....
