High Tech Genetics II Yesterday I introduced you to a new tool for evaluating genetic potential of beef cattle. I'm Jeff Keane; today I'll tell you a little more about this new technology. I just read an article in "Beef" magazine written by Wes Ishmael explaining a new tool for calculating potential performance of beef cattle called "molecular genetic value" or MGV. Until now beef cattle worth was discussed by what could be seen or measured. MGV is an evaluation at the cellular level studying DNA markers to predict performance. That's about as far as I need to go to explain the process because that's about as much as I could explain. I've sat in on a discussion of similar techniques at a cattlemen's convention and understand the potential, but I'm a little fuzzy on the details of the concept. I do understand how beef industry segments might use this new tool. Ben Brophy, director of genomics commercialization for Cargill's cattle feeding and beef processing enterprises says cattle could be tested to match the right cattle with the right management. What he is talking about is not overfeeding an animal that doesn't have the potential to reach a certain quality grade, or not even feeding one that doesn't have the ability to gain fast enough to make money. This new technology that could be used to provide consumers with consistent, high-quality beef is sure on a whole new level from rounding up Longhorn steers on Texas ranges, trailing them north to Kansas, and shipping them points east to yesteryear's consumers.
