I also breed ASFs, been breeding em for years. I agree with everything else thats been posted here. In addition, one thing thata been successful with my groups is making sure they have plenty of things to chew on. ASFs love to chew the crap outta stuff. I think its a stress release for them. Toilet paper or paper towel tubes, small cardboard boxes, dog bones, wood caves, etc. If theres nothing for them to chew up abd theyre stressed, they may take it out on their babies. Ive never really had a problem with mommas eating their babies.
