[QUOTE="DOC HARRIS, post: 320370, member: 1683"] Clem - The answer to your question, as with almost everything else, is more involved and extensive than just a simple few word answer. I would suggest that you contact the American Angus Association for a more complete understanding of the [b][i]reasons[/i][/b] for all the particulars involving the different traits and characteristics management technics necessary for a successful operation. To give you a simple answer to your question, assuming that your heifers are in the range of Frame Score 4.5 - 5 or 5.5, I would say the BW EPD for Bulls to be used for first calf heifers would be in a range from -2.0 to +1.5, considerating that the bull has a reasonably high Accuracy number (1.0 being as high as they go). An untested young Bull can have all kinds of accolades and recommendations, but because he has no calves by which to guage his abilities, his EPD's will be Interim, or have an "I" preceding the EPD number, which is an estimate. You can use this as an idea of what his actual EPD would or will be in the future, but it is only a guess - educated guess perhaps, but a guess nevertheless. The potential sire should have shoulders which are not so wide, or 'open', so as to make the calving by the heifers more easily accomplished. After the first calf, they can tolerate BW EPD's higher than when they are a 'first-calf' heifer. My personal preference is to not have "MILK" EPD's of the Sire be higher than +22 - +25, preferably lower. I will probably get a rash of arguments on that, but I am adament about it for a variety of reasons, which I won't elaborate on today. I hope this helps you, Clem. DOC HARRIS [/QUOTE]
