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

eBEEF Monday: Simple Inheritance in Beef Cattle

Managing traits controlled by simple inheritance has economic importance to many beef operations. Understanding simple inheritance can assist producers in breeding cattle that are the phenotype desired, such as polled, or avoid undesirable traits, such as lethal defects. This information sheet explains how simple inheritance works and how it can be managed. See Fact Sheet for more information on Simple Inheritance in Beef Cattle.

eBEEF Monday: Parentage Testing

Parentage testing can be a valuable tool for both seedstock breeders and commercial producers.  This fact sheet covers how parentage testing works and tips for using parentage testing successfully. Parentage testing is often thought of as a tool that is only applicable to seedstock producers, but in fact, there are benefits to commercial producers as well. Parentage testing not only ensures correct pedigree, but can provide information to make important management decisions for commercial producers. Knowing some of the basics of parentage testing and how it works can help a producer understand the benefits of testing. See Fact Sheet for more information about Parentage Testing.

Answering Genomic Prediction Questions

I received the following comments and questions from a beef breeder. 1. From a producer perspective I experienced the implementation of NCE [National Cattle Evaluation] from the beginning to the Genomically Enhanced phase we are experiencing.  I saw line breeders with lifetimes of work begin to outcross in order to keep up.  From the stuff I have read from Dr. Wilhelm two things stuck me.  Maybe my understanding of these is out of context but he felt one of the positives of numerical breeding was going to be the elimination of line breeding.  The second was his statement that creating some kind of index or indices with the merging the individual traits would be a mistake. ARE THE UNINTEDED CONSEQUENSES OF ELIMINATION OR DEVALUING OF LEGACY GENETICS AND LEGACY BREEDING METHODS SOMETHING TO WORRY ABOUT or conversely are the consequences of a narrowing toward what is bigger and better something to worry about? Expected progeny differences (EPDs) from NCE are simply a tool. The br
