Dr. Jamie Courter is your Mizzou Beef Genetics Extension Specialist

Image
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...

American Gelbvieh Association Releases Genomic-Enhanced EPDs

The American Gelbvieh Association (AGA) has released genomic-enhanced EPDs with the fall 2014 international cattle evaluation. Genomic-enhanced EPDs (GE EPDs) combine pedigree, individual performance and genomic information to save time and money, reduce risk, and accelerate the rate of genetic progress.

GE EPDs provide more precise EPDs based on a combination of both phenotype and DNA. One major benefit of these EPDs is risk reduction through increased accuracies. These increased accuracies save time when assessing young breeding stock as well as deliver commercial customer confidence when buying seedstock. Herd improvement is accelerated when breeders can more accurately identify young individuals with the best genetics.

GE EPDs also give the chance to collect data on economically important traits, which are expensive or difficult to measure.

The information from the genomic data can be as informative as a bull's first calf crop or a cow's lifetime production record. Since the genomic data is incorporated directly into the EPDs, cattle producers will not have to learn how to interpret the new data.

Development of GE EPDs for Gelbvieh and Balancer® animals has been in progress at the AGA since 2012, starting with the Genomic Pioneers project. This project helped to build a diverse panel of Gelbvieh and Balancer genetics to be the foundation genetics for the calculation of the GE EPDs.

"The AGA has been working closely with the scientific community over the past couple years to build the training population for developing GE EPDs for the Gelbvieh breed," says Susan Willmon, director of breed improvement at the AGA. "Implementing genomic-enhanced EPDs is a high-priority goal in the AGA's strategic plan and we are excited to be able to offer this tool to our breeders and their commercial customers."

EPDs that are genomically-enhanced will show up on the new American Gelbvieh Association Registry Service as highlighted in yellow. All animals with these enhanced EPDs will also have the AGA GE EPDs logo on their registration certificate.

For more information on GE EPDs visit Gelbvieh.org or contact Susan Willmon at susanw@gelbvieh.org or call 303-465-2333.

New Show-Me-Select Sire EPD Requirements Announced

Image
At the January 4th Show-Me-Select Board of Directors meeting, new service sire EPD requirements were approved. All sires, artificial insemination and natural service, must meet minimum Calving Ease Direct (CED) EPD requirements. In addition to yearly updates, two changes were made. First, no Birth Weight EPD requirement will be published. All commonly used breeds now have CED EPDs available. Second, all breeds in the International Genetic Solutions (IGS) genetic evaluation are now set to a common requirement. In the summer of 2018, breeds within the International Genetic Solutions switched to a single-step BOLT multi-breed genetic evaluation. The EPDs for animals in the IGS genetic evaluation are directly comparable across breeds. In 2017, the Red Angus requirement for CED was a CED of 8, which represents the 30th percentile. Less than 5% percent of heifers breed to a bull with a CED EPD of 8 or larger had calving difficulty. We feel that this require is meeting the need to re...

Show-Me-Select Board Approves Genomic Testing Requirement for Natural Service Sires

Image
All bulls purchased after February 1st, 2019 for use as natural service sires in the Show-Me-Select Replacement Heifer Program ™  must be DNA tested to have genomic-enhanced EPDs. All bulls used as natural service sires after February 1st, 2020 must have genomic-enhanced EPDs, regardless of when they were purchased. Seedstock producers classifying bulls as Show-Me-Select qualified in sale books must have genomic-enhanced EPDs on those lots. Bulls purchased prior to February 1st, 2019 will be grandfathered into the program, as is the common practice with all natural service sires. However, this grandfather grace period will end February 1st, 2020. At that time for a bull to qualify for use in the program, it must have genomic-enhanced EPDs. Why the change? The Show-Me-Select Replacement Heifer Program has the goal of producing premium heifers that perform predictably as 2 year olds. The program has a history of requiring Show-Me-Select producers to go beyond typical...

Bob Hough Comments on Changes at Breed Associations

Bob Hough recently posted the following comment on Facebook (posted with his permission): Early in my career at a breed association, the much beloved American Angus breed executive told me that the secret to success running a breed association was to have a top junior program, keep the books straight, and make sure the numbers (EPDs) don't change. This philosophy meant Angus valued stability in their genetic predictions over keeping them up-to-date with the latest science. The Angus Association also marketed extremely effectively the infallibility of their EPDs because of the size of their database. I will start with the later. Yes, a database needs certain critical mass to make sure the animals are tied, but that can be achieved in a modest size database. After that, data quality far and away outweighs data quantity in assuring the most precise and reliable EPDs possible. On the former point, Angus breeders are simply not use to change. This is not the case in most breed associ...
