[QUOTE="Idaman, post: 784096, member: 14119"] You are correct. I do have a measured amount of faith in the EPD that helps to arrive at the derivative that makes up the $EN for mature size. In the Diamond D example the raw weaning weight is used and the estimated condition score are used to arrive at the % cow calf ratio. When I look at this ratio I then observe the $EN number to see whether we have a smaller fat cow or a larger cow carrying a lot of fat. If we start with an 1100 lb. cow and then adjust for an 8 condition score which is -240 then we continue with the resultant 860 lbs. times 77% we come up with a 662 lb. calf which seems possible to me.
