That's Justin Rhodes I have been following his Youtube channel for a while now. I do not recall the specific breed. But, those pigs are particularly small and nonagressive. He will broadfork the entire area while the livestock is there (as a form of exercise). Also, when he finds deep rooted weeds with the broadfork he dumps grain down the holes so the pigs will go after it and dislodge the roots. So, this is not a labor free method. But, he is getting help with tilling and fertilization from his livestock.
