Jared Decker, PhD University of Missouri One point must be clear from the very beginning: EPDs work. When we select parents based on EPDs the genetic merit
for that trait increases in our herd. When we select the parents using EPDs the
performance of the next generation improves. EPDs
Defined EPD stands for Expected Progeny Difference. These three words are loaded
with meaning, thus the need to define them here. The most loaded word is
Expected. Here we use Expected the way a statistician would use the word.
Expected means we are making a prediction of a future value. But, in this
context, Expected also means we are describing the average of a group. What is
the group for which we are predicting the average? We are predicting the
average performance of the Progeny or calves out of an animal. An animal’s own
performance and its EPD can be quite different, because that is not the purpose
of an EPD. The EPD is predicting the average performance of that animal’s calf
crop. Finally, EPDs are u…
Commercial beef producers will get more traits and selection index tools in the upgraded Igenity® Beef profile.
The Igenity Beef Profile will offer 16 traits for $29, replacing Neogen’s 13-trait Igenity Gold ($40) and 6-trait Igenity Silver ($25) tests. The upgrade includes new predictions for weaning weight, yearling weight and hot carcass weight for a total of 16 traits scored on a 1–10 scale, plus two new selection indexes.
“Our customers will be getting a powerful new profile at even greater value,” said Dr. Stewart Bauck, vice president of agrigenomics at Neogen. “The Igenity profile was designed and validated for crossbred or straightbred cattle with backgrounds of Angus, Red Angus, Simmental, Hereford, Limousin and Gelbvieh.
“Most DNA profiles are breed-specific,” Bauck continued. “The novel design of Igenity Beef allows for the accurate prediction of performance in both crossbred or straightbred cattle among the target breeds. This lets cow-calf producers use a DNA profile to …
What does it mean to have a successful cow herd in the Ozarks? What should be the genetic focus? How do we select and manage cattle to perform on toxic endophyte-infected fescue? What technologies can be used profitably? What marketing opportunities could add value to the cattle? These are questions facing every beef operation in Southwest Missouri, including the University of Missouri Southwest Research Center. As the Center moves away from a focus on grazing dairy production, faculty and staff at the Southwest Research Center and on campus at the University of Missouri recognize there is now an opportunity to increase the emphasis placed on beef cattle Research and Extension at the Southwest Research Center. With support from the Southwest Research Center Advisory Board and key stakeholders in the regional and national beef industry, an effort to expand and improve the Southwest Research Center beef herd is now underway.
