Dr. Jamie Courter is your Mizzou Beef Genetics Extension Specialist

By Jared E. Decker Many of you have probably noticed that things have been a lot less active on the A Steak in Genomics™   blog, but you probably haven't known why. In January 2021, I was named the Wurdack Chair in Animal Genomics at Mizzou, and I now focus on research, with a little bit of teaching. I no longer have an extension appointment. But, with exciting news, the blog is about to become a lot more active! Jamie Courter began as the new MU Extension state beef genetics specialist in the Division of Animal Sciences on September 1, 2023. I have known Jamie for several years, meeting her at BIF when she was a Masters student. I have been impressed by Jamie in my interactions with her since that time.  Dr. Courter and I have been working closely together the last 6 weeks, and I am excited to work together to serve the beef industry for years to come! Jamie holds a bachelor’s degree in animal science from North Carolina State University and earned a master's degree in animal

ReproGene Workshops: High-quality, profitable beef made possible by genetic tests

Five meetings explain options.

Making quality beef for more farm profits becomes predictable by using genetic testing.
Meetings across Missouri will review current breeding technology and explain new genomic tools.
University of Missouri Extension specialists plan meetings in Maryville, Kingsville, Macon, Springfield and Jackson.
The five meetings are called "ReproGene: Taking the next steps in beef cattle reproduction and genetics."
Missouri herd owners can learn to produce more profitable cattle with better genetics. EPDs, expected progeny differences, guided improvement.
With genomic testing, all heifers in a herd can be DNA-tested. This provides accurate predictions of future calf performance.
Now producers can use genetic information on the male and female side of the herd, Decker says.
On the reproduction side, Dave Patterson will tell of new research that offers better conception rates from artificial insemination (AI). Split-time AI gets more cows pregnant.
Also coming is the use of sex-sorted semen. This allows making heifers or bulls. The sex can be set before insemination.
Many new tools are available on the genetic side, Decker said. Mostly, the tests are breed-specific. Different tests are used for registered and commercial herds. However, some tests work on crossbred or mixed-breed cattle.
DNA samples can come from blood drawn from a calf’s ear or from the root bulb from tail hair. Many producers use convenient tissue sampling units that take a punch from the ear.
New technology allows breeding higher-value animals, selecting traits that improve pregnancy rates and carry through to final product at the packing plant.
To gain full advantage of the advances will take more attention to marketing of cattle. Further, genetic predictions can actually be used to place a value on the calf crop. Now, the producer can get paid for the genetic merit of their cattle through various programs.
Those attending can start on being a step ahead in building profits in their beef herds. As cattle prices fall, quality premiums gain value. Efficiency improves and adds sustainability.
Options will be explained in the three-hour sessions. A meal will be served at each location.
