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...

how and why did any re-sortings or rankings occur?
Genomic-enhanced EPDs (and all EPDs in general) are predictions based on random effects. Random effects always have a certain degree of uncertainty, and with EPDs we express this uncertainty as an EPD accuracy. When we add additional data to random effects the predictions change. When genomic predictions are re-estimated the random effects change. This is especially significant for families within the breed have not been previously sampled. When these families are sampled the predictions for animals within these lineages change. This is the major source of re-ranking in recalibration.
