Assuming these are domestic hogs, At 9mos old and 125lbs, not much fat on them at all. If domestic, what breed of hogs are they? And do you know how they were raised?
There have been studies done that say, especially on certain breeds of hogs, that boars can be put to pasture to free range for a month or two and that can better the taste of the meat as they are not in a confined small area and have less of a tendency to eat their own feces. Which will cause the meat to taste foul.
But many of these studies have the boars being harvested at 6-7 mos.
Some studies have also included pasturing the boars without the presence of any sows...stating that after a few months that the absence of a female, the boars produce much less testosterone hence having less tendency to have boar tainted meat.
There is much reading that can be done but without knowing a bit of their history or breed, it's a roll of the dice how the meat will turn out.
