[QUOTE="smnherf, post: 1216251, member: 3235"] I don't know squat about Simmental epds, but looking at them as yearling bulls and I would pretty much have to throw them out and look at the bulls as there just isn't enough differences other than a little CE and REA and they are both in the upper 20% for both traits within the breed. With yearling bulls and the low accuracy of epds, there just isn't enough difference to separate these two bulls on paper. Now for me I would have to look into how much data that supports those epds. Does one have several hundred head of complete data collected on the sire and maternal grandsire and their lineage or is it simply a mating of extremes where the epds are averaged to come up with the great epd profile supported by several generations of cattle that just have a handful of data collected on them in the previous 3 generations.
