[QUOTE="DOC HARRIS, post: 248158, member: 1683"] This Hypothesis is fine - - as far as it goes! BUT, it does not go to the extent that was originally intended. "[b]MATERNAL MILK EPD (Milk)[/b] - is a predictor of a [i]sire's[/i] genetic merit for milk and mothering ability as expressed in pounds of calf weaned by [i]his[/i] daughters compared to daughters of [i]OTHER SIRES[/i]. In other words, it is that part of a calf's weaning weight attributed to milk and mothering ability." ([i]emphasis[/i] is mine. Doc Harris) In my discussions of the values and merits of EPD's, [i]per se[/i], I find that when it is difficult to be in accord with others the reasoning usually is because of equivicating and quibbling over 'presupposed' facts, unsupported by total cognizance of the literal and realistic definition of ALL "EPD's", which after all are [b]"EXPECTED PROGENY DIFFERENCES"[/b] In this particular case of 'Milk' EPD's, IN MY OPINION, most of us have taken a cursory view of EPD's, in our eagerness to achieve perfection in our breeding programs, have leaped to conclusions that they (EPD's) were [b]THE[/b] answer to all of our hopes and dreams. With that presumption in mind it became easy to take the "path of least resistance", disconnect our cogitating abilities, and lapse into a fairy-land dream world of breeding beef cattle "by-the-numbers", and STOP thinking about reality - - point in fact - - in concert with PHENOTYPE! The can be NO repudiation of this statement: [i]There is absolutely [b]NO ONE SINGLE ANSWER[/b] to Genetic Perfection![/i] WHY!?? Because [b][i]PERFECTION[/i][/b] is in the eye of the beholder. If perfection could be achieved, easily or not, ONE Bull and ONE Cow could produce ALL of the progeny in the Beef Industry, and we could all retire and cease struggling and arguing. We need to get real here, Folks! Using EPD's in conjunction with Phenotype and our good common Horse (if you'll excuse the expression) sense, is tantamount to a Championship Chess Game - it takes knowledge, intuition, and more good fortune than anyone possesses just to make a step forward in our breeding programs - but it CAN be done - as many good breeder's have proven. But KNOWLEDGE is paramount in the mix and we can never stop learning if we care to advance! DOC HARRIS [/QUOTE]
