From what I understand, you add 2.7 to the 3.6 BW EPD on the Hereford to compare it across breeds, so he would have a 6.3 BW EPD.dun":1q7bywtx said:Never have figured it all out but according to the 2008 across EPD table a 2.7 Hereford BW is the equivilent to 0 in angus

On the table, where there is a negative in front of the numbers, you subtract that from the animal's EPD, and the positive numbers you add.
