Extract

Ultrasound technology provides a oportunity to quickly and economically estimate carcass atributes on the live animal (Brethour, 2000). In general, this technology has been used to detect variation for fat depth and ribeye area (longissimus dorsi muscle) in performance tested yearling bulls at several countries. In the present study, real time ultrasonography was used to predict the ribeye area (RA) and the subcutaneous fat thickness (FT) in Nellore crossbred.
