Just curious, have you ever tried weaning at an earlier age before? Or is this your first litter ever? I have raised several different breeds before, but now solely raise Durocs. Through multiple trials and monitoring both the sows and piglets, I have found (at least in my experience) that weaning in the 3.5-5 week range yields the fastest growing and more tame piglets, along with a happier and healthier sow as well. Great writeup nontheless!
