[QUOTE="J+ Cattle, post: 1731476, member: 4063"] Instead of looking at the papers, I would suggest that you go to the Angus.org website and lookup the animal by registration number. The EPDs change all the time and as more data gets reported on offspring the sire data should become more accurate. If the animal was HD50K tested by a DNA sample that also improve the accuracy. Take BW EPD as an example, the +4.7 number is not based on breed average, you use it to compare to another sire. One sire has a BW of +4.7 and another has a BW of -0.5. The prediction is that the first sire will have calves that are 5.2 lbs heavier on average than the second sire. The number under the BW number (.80) is the accuracy of the prediction which comes from actual BW measurements reported by others that have used the sire. I hope this helps. [/QUOTE]
