What does a full grown show pig boar average weight? And does anyone have any pics of a 3 year old or older show pig boar. I am new to the show pig world and have seen many pics of boars in the show ring but was curiouse of how they look fully matured years later. I remember years ago my Uncle had a Duroc boar on the farm and man was he huge . He was about waist high and wieghed well over 600 lbs.
