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

Doctor Bovine Genome
or: How I Learned to Stop Worrying and Fix the Assembly

I know, this is a very strange title for a post.  More about that later... USDA Fellowship In this post I want to introduce you to part of my day-to-day research.  In August of this year, I was awarded a USDA NIFA Postdoctoral Fellowship.  I was awarded this fellowship for two reasons: to prepare to become a leader in agricultural science and to complete a specific project.  My project is reassembly of the bovine reference genome sequence. Motivation: Why are we reassembling the bovine genome? The completion of the draft human genome sequence was announced to much fanfare in 2000.  But, the work of finishing the human genome still continues.  Two versions of the bovine reference sequence, by the Baylor College of Medicine and the University of Maryland , were published in 2009.  At that time the bovine genomics community began discussing how to improve the draft assembly.  Key players suggested that more sequence data on  L1 Dominette 01449, the cow on whom the reference s

Take Care When Collecting Hair Samples

I received this reminder from the American Hereford Association this morning: Take Care When Collecting DNA GeneSeek Inc., Lincoln, Neb., is the new American Hereford Association (AHA) DNA lab ( learn more ). The switch has not been without its challenges and one of those is that the new technology, SNP based, requires a lot more DNA than the previous technology. In other words, we have had several requests that have not fully been reported because the lab will not have enough DNA for each of the tests. Assays are different for the abnormalities, parent verification, horned/polled and 50k GE-EPD. The bottom line is the lab needs a minimum of 80 hairs with the follicles and the best place to pull is right above the switch on the tail. This technology is also very sensitive to contamination due to pour-ons and other insecticides, so please keep that in mind. If you have any questions, contact  Jack Ward  at 816-842-3757. SNP assays require large amounts of high quality DNA. From
