I've got 2 pigs going to slaughter on Thursday. I will not have an opportunity to get a live weight on them. I'd like to figure out approx. what they weighed based on their carcass weights. What is the % generally with pigs?! My FIL suggested it is like 65% carcass of live weight. Any other thoughts on this? Babe and Porky aren't nearly as interested in this calculation as I am!
