That would be an interesting number to see. I don't think it changes the potential for their frame at all just the amount of meat and fat on that frame. I guess what I am saying is a boar that has a huge frame is still going to get bigger than a barr with a smaller frame, some of the size is genetically predetermined. With a lack of hog on hog fighting you usually have large teeth (especially if the whetters were knocked out) wihch makes most hunters happy and the any additional weight is an added bonus. The table is where the biggest difference is noticed.
Why does it taste different? Same food sources, but eat more of it. But if they travel more or just as much as a regular boar I wouldn't think their would be a difference in.....?...tenderness? Lack of testosterone? Not debating, just thinking out loud. What is it that makes the difference?
It is called 'boar taint'.. Same reason all show pigs are cut hogs. You may get lucky and can eat a young boar or catch a feed grain boar that's not bad, but trust me you'll know the smell and taste when you do get ahold of it. I've seen some guys ruin whole batches of sausage by adding a boar hog to it
http://en.m.wikipedia.org/wiki/Boar_taintWe cut hogs for 2 reasons, trophy aspect and and sausage aspect. Honestly the return rate is very low. It's always a special event to repo one of your own Barrs. Not everyone has the property to do it, but around east Texas where we hunt everyone I know Barrs hogs
