Ultrasound Definitions Ribeye Area (REA) Area of the longissimus muscle, measured in square inches. The trait is moderately to highly heritable and gives an indication of overall carcass muscling. Fat Thickness (FT) An external fat measurement taken between the 12th and 13th ribs, measured in inches. Rump Fat (RF) An external measurement taken between the hooks and pins, measured in inches. The rump fat and the rib fat measurements are used to determine the overall external body fat. Intramuscular Fat (%IMF) Percentage of fat in the ribeye area muscle (similar to marbling). The field technician collects four images and the values generated by the interpreting software are averaged for an overall %IMF. Marbling directly contributes to beef palatability. Lean Yield (LY) Carcass yield is expressed as the dressing percentage.
Genomic-enhanced EPD (GE-EPD) are important because they utilize genomic test results in addition to pedigree, performance and progeny data for increased reliability of an animal’s EPD
