Ultrasound technology offers a low-cost alternative to expensive and time-consuming progeny testing of beef sires for carcass merit. Expected progeny differences (EPDs) for carcass traits such as fat cover, ribeye area, and marbling would provide a tremendous tool to the beef 'cattle industry for producing a high quality, uniform end product. With these EPDs, breeders and commercial bull buyers will be able to directionally change the end product through genetic improvement programs. The objective of this report is to relate the accuracy with which fat cover and ribeye area can be measured with ultrasound equipment when compared with carcass measurements and to demonstrate how serial scans with ultrasound relate changes in body composition of cattle as they mature.
