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

North American Limousin Foundation Releases Recalibrated GE-EPDs

By Joe Epperly, NALF assistant executive director

Limousin breeders and their commercial customers benefit greatly from new breeding and selection tools. The North American Limousin Foundation (NALF) has launched genomic-enhanced EPDs (GE-EPDs) with the fall 2015 international cattle evaluation. This provides GE-EPDs for all Limousin and Lim-Flex® animals that have completed DNA testing for genomic profiles.

A recalibration in cooperation with GeneSeek® and the Canadian Limousin Association has supplied genomic profiles on more than 4,500 Limousin and Lim-Flex animals. Molecular breeding values from either a high- or low-density genomic profile test are then blended into EPD calculations to produce GE-EPDs. This recalibration has led to the doubling of the number of animals included, the number of traits enhanced, and the genetic correlations.

The advantage to animals with GE-EPDs is increasing EPD accuracy values on many traits equivalent to having 8-20 progeny. This adds greatly to the predictability in selection for genetic merit of young, unproven seedstock. Animals that are genomic-enhanced will have the NALF GE-EPDs displayed on their animal detail screen and performance reports in the NALF-DigitalBeef platform. Traits that are genomic-enhanced are highlighted in yellow on these reports.

"We are excited to offer cutting edge tools for the selection of superior genetics to members and commercial producers purchasing Limousin and Lim-Flex animals. NALF has options for DNA testing that fit both your budget and needs for various traits," says Brittany Barrick, NALF director of registry and performance.

For questions regarding DNA testing options and procedures, contact Brittany Barrack, NALF director of registry and performance at 303-220-1693, ext. 57 or Brittany@NALF.org.

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 cat

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
