[QUOTE="DOC HARRIS, post: 576223, member: 1683"] Frankie- I have noticed on most of the threads the last week or so that the general 'thought trend' is leaning toward the discussion of EPD's, particularly "Milk" and "SC". Given that the subject of EPD's is, arguably and admittedly, a perplexing and Herculean task - at BEST, I commend Frankie on this post inasmuch as she points out that they are taking a "wait and see attitude" on the uses of [i]certain[/i] EPD's relating to Weaning Weight, Disposition, Docility, and ( subtly expressed in this post) how they plan to utilize EPD's [b][u]WITH[/u][/b] the EPD's of the COWS to which their bull subject will be bred! In recent discussions on these posts, I have noticed that the [i]dangerous[/i] trend of SINGLE TRAIT SELECTION is again lunging into the discussions with some poster's. I would suggest that the [b][i]antagonistic [/i][/b] characteristics ( low BW vs. High YW, low BW, High Milk vs. CW [Carcass Weight], and various SC EPD's as they relate to the bull's daughters' Fertility potentialities), be understood before arbitrarily being condemned and denounced 'out-of-hand' by those who don't comprehend the functionality of the EPD 'Evaluation of Performance' methods in the first place! The Accuracy (ACC) figures which relate to the reliability of ALL EPD's seem to be taken as an "afterthought" in the mind's of some breeders. [b]"SINGLE -TRAIT-SELECTION[/b]-thinking" is a formula for failure - not only in breeding, but in understanding what the management of EPD's resulting in successful breeding experiences is all about in the first place! Ignoring the "Accuracy" figures is like "buying a pig in a poke". Having to "wait and see" can be minimized by watching the Accuracy figures and 'betting' on proven genetics. Good work, Frankie!
