Cattle Breeding and Reproduction

We’ve got a cornucopia of Estimated Progeny Differences; in the future, says Dr. Wade Shafer, we’ll have a better idea of what they all mean to profitability. “In the past,” says Shafer, Director of Performance Programs for the American Simmental Association, “the conventional approach has been we just collect data on everything we can get our hands on. Ideally we’ll calculate EPD’s on that, because we know EPD’s are the best estimate we can get when it comes to a particular trait. But then, we just kind of leave things hanging in the wind; we don’t really know how much weight to put on this huge array of EPD’s we’ve amassed.
