How big should a pig be when it is butchered? I know that 20 years ago the ideal weight was 225 to 250. Has this changed? Last year I turned down an opportunity to buy half of a 440 pound pig, but I was wondering if it would have been OK. I DID buy hallf of a pig once and it was lovely. I turned down the half-pig because I didn't want to end up with a fatty animal.
