[QUOTE="Brandonm22, post: 623491, member: 7645"] The industry is inevitably moving towards the point that there is a unified across breeds EPD database where +50 Weaning Weight EPD means exactly the same thing whether we are looking at Angus, Hereford, Charolais, or Brahman bulls or some composite animal with all four breeds in him. We are not going to maintain 40 seperate EPD databases of questionable validity indefinitely into the future. The EPDs are transitioning from a tool seedstock breeders use to plan matings of pure stock to pure stock to a tool commercial cattlemen use to plan meetings. We know where we want to go. Now the questions are WHEN do we get there, HOW do we get there, and how do we calculate accuracy if/when we do get there. IF we are at the point where Hereford is actually using data from commercial Hereford, Angus or even crossbred cows to calculate EPDs I am completely fine with that (in theory). If Alex's bull underperformed bred to cows in that contemporary group......and I am assuming his competition was another Hereford bull......then we would WANT for that data to be used in his EPD caclculation because that does tell us something about how the bull performs.
