You should use 60 pigs per pen to enable a continuous breeding loop. Use 12 blocks for the hopper timer that fires the AoE "love" arrows. Position your 60 pigs 6–10 blocks above the point where the "thunder" arrows are fired, to prevent them from transforming. You should also have a carrot farm, a rice (wheat) farm, and cinder.
