Estimation of carcass composition in cattle. 1. Estimation of carcass composition in live cattle from ultrasound measurements and live weight


, : Estimation of carcass composition in cattle. 1. Estimation of carcass composition in live cattle from ultrasound measurements and live weight. Archiv fur Tierzucht 36(3-4): 315-324

Ultrasonic scanning at the level of the 1st and 5th lumbar vertebrae was carried out on 648 bulls of 5 breeds and 1 crossbred just prior to slaughter at 400 or 500 kg live weight. Weights of carcass cuts and carcass dissection data were also obtained. Repeatabilities of ultrasonic measurements were 0.73-0.98. Correlations between ultrasonic and carcass loin-eye area were 0.68-0.80. Correlations of carcass cut weights with ultrasonic and carcass loin-eye areas and live weight are tabulated.
