Lamb and beef. Never tried the pork. I did raise some "pastured pork" one time. 9 total...only "pastured" because the rascals wouldn't stay in. Long story there, but occasionally they got in with the fats and bellied up to the feeders. Didn't seem to have any effect on the meat quality, but they only escaped into that pen a few times...probably not enough to make much of a difference in the meat. It was a 3 way mix at that time with soyhulls and CC.Are you talking about pork also, or just lamb? I am curious.
