I took a boar to slaughter earlier this year which was of a similar age and the sausages came back with a strong taint in them. Even with the meat seasoned I could tell the difference between our normal sausages and these, the OH didn't seem to mind the taste but I stopped eating them because of it. It can also depend on if he has been around any females recently as our boar was near to our sows a week before slaughter, they where on heat and I know he was horny. I won't be sending any more boars of that age to slaughter again, but you may be lucky!!
