摘要

The last issue of Carcass Ultrasound 101 dealt with selection practices used to increase muscle via ultrasound, mainly through the use of Ribeye Area (REA) Expected Progeny Differences (EPD). This issue turns to the quality side of ultrasound technology via selection for Percent Intramuscular Fat (%IMF) or marbling. The ability of ultrasound to measure carcass quality significantly helped launch the science, since cattle breeders cannot "see" marbling from viewing the live animal. In 2000, May et. al. used highly trained personnel to asses carcass quality and only mustered a correlation of 0.30. Recent validation trials of CUP Lab software showed ultrasound %IMF correlation to carcass marbling score just under 0.80.
