No. But they are already healthier than most tame hogs fed in SPF barn. They are free range, few have diseases and don't walk around in their own crap.
We trapped them for years and at times fed them out before slaughtering them. They are very lean, not bred for quick growth. No hormones. Made some really good whole hog sausage. Barely enough fat to keep from sticking in the pan. EXCEPT: if they have been feeding on peanuts. If so, avoid. You cannot get the oil off of you or the equipment.
No peanuts around here.
