My son has sold 3 hogs by the live weight. Instead of taking each hog in and weighing separately, I suggested we just calculate their live weight from their hanging weight. Everyone agreed that this would be fine. I used to have something that told me what this was. Today he took all three hogs in and of course now I discover I no longer have the formula. I heard from the locker plant and got all three hanging weights and have no idea how to figure it. After slaughter Hog # 1 weighed 149 Hog #2 weighed 127 Hog #3 weighed 171 Thanks!
