Ultrasound has become widely used by the seedstock industry as a selection and evaluation tool. Ultrasound estimates of Ribeye Area, or REA, Intramuscular fat, or %IMF (marbling), and Rump Fat have been used to develop several EPD’s for many breed associations. Despite widespread use by seedstock producers, there is still some apprehension by commercial producers. Additionally, the use of ultrasound for commercial herd replacement decisions, used by some producers, is worth discussing. There are both benefits, as well as cautions, to using ultrasound generated information in a commercial beef herd.
