An old butcher and friend of mine told me that 41% of live weight was meat weight if there is no waist and the cutting is done clean.
So you loose 24% to 25% in field dressing. A 450 pound hanging animal weights 562 live.
417% of 562 = 230.62 So call it 231 pounds if it was a super clean kill, and if the butcher is very good at what he does.
