April 19 Webinar by Genetics Experts to Give Cattlemen Guidance on Creating the Best Herd
final webinar in series focuses on bull selection
CO (April 12, 2018) – This year’s edition of the NCBA Cattlemen’s
Genetics Webinar Series comes to a close April 19, with a special
presentation that puts a focus on honing bull selection. The
National Cattlemen’s Beef Association teamed up with six genetics
specialists from across the country to offer this series, which kicked
off Jan. 18. The Genetics Webinar Series was designed for producers who would
benefit from genetics knowledge, from the experienced seedstock breeder
to someone who might be new to the cattle industry and needs to better
understand genetics. It is being coordinated by the NCBA producer
education team. Earlier webinars were “The 4 S’s of Crossbreeding:
Simple, Structured, Successful and Sustainable,” “Show Me the Money!
Are there EPDs for Profit?”, and “Fake News: EPDs Don’t Work.” These
webinars can be accessed at www.NCBA.org
under the Producer Education tab. Titled “Putting the Tools to Use: Buying Your Next Bull,” the April 19
webinar puts the genetic concepts covered in the first three seminars
to work, as attendees will go to a virtual bull sale and select the
best bull from a sale catalog for two distinct production scenarios.
The webinar begins at 7 p.m. CDT. Leading discussion on the topic at the webinar will be Matt Spangler,
Ph.D., associate professor and extension beef genetics specialist at
the University of Nebraska – Lincoln, and Bob Weaber, Ph.D., professor
and beef extension specialist at Kansas State University. Joining in
the discussion will be other members of the eBEEF team, a group of six
genetic specialists from five academic institutions who have invested
time and resources in the advancement of the cattle industry through
genetics. According to Josh White, NCBA executive director of producer education,
the genetics webinar series has been an effective extension of NCBA
educational webinars, which was started several years ago. “Some of the
largest participations in our webinars have been for genetics topics in
the spring,” said White. “This 2018 partnership with the eBEEF team has
been a terrific addition to the education we can provide.” Cattle producers are invited to join the webinar live, although
“homework” for the seminar – available at www.NCBA.org
– is advised. The homework includes the eBEEF bull sale catalog and the
eBEEF bull selection scenario. For

National Cattlemen's Beef Association (NCBA) has represented America's
cattle producers since 1898, preserving the heritage and strength of
the industry through education and public policy. As the largest
association of cattle producers, NCBA works to create new markets and
increase demand for beef. Efforts are made possible through

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 …

Can we be frank
for a minute? It is quite simple: EPDs work. When we use EPDs to make selection
decisions (which bulls to buy, which females to keep and cull), the performance
of our herd improves. Let’s discuss why EPDs work, how they can be used, and
pitfalls to avoid. Defining EPDEPD stands for
Expected Progeny Difference. “Expected” in this context is a loaded word. We
use it here the way a statistician would use it. Expected means we are
describing a prediction of the future. Expected also means we are discussing an
average, not a single observation. What is the average that we are predicting
with EPDs? We are predicting the average progeny, or the average of an animal’s
calf crop. Finally, when we are discussing EPDs we are discussing differences.
Either the difference between two animals or the difference b…
