The aim of our work was to estimate genetic parameters for ultrasound measurements and furthermore to estimate genetic correlations of ultrasound measurements with growth and carcass traits. Live animal ultrasound measurements, field test data and data from commercial slaughterhouses were used for the evaluation. The results of the ultrasound measurements included four carcass quality indicators measured on live animals – rump fat thickness, rib fat thickness, eye muscle area, and intramuscular fat content – so-called marbling. In addition, body weight at scanning and scrotal circumference were also recorded as part of the measurements. Two traits were selected from the field test for evaluation – adjusted weaning weight and adjusted yearling weight. Data from commercial abattoirs included three traits – carcass weight, conformation class and fatness class.Angus. The results support the potential value of live animal ultrasound measurements in the Czech Aberdeen Angus breeding program to generate indicator traits for carcass quality.
