YikesWere they low on food or water? Mine don't cannibalize their pups anymore, and it was a combination of making sure waters were ALWAYS full, weaners were always weaned on time (before mom had the next litter), and food was always available. I fed off any ASFs that had cannibalized before, and started new groups. Haven't had a problem in a long, long time.
Toss in a block of 2x4 or something they can stand on and push up to the water spout so they can reach it.
