Genetic parameters were estimated for body weight at scanning (SCW), scrotal circumference (SC), rump fat thickness (P8FT), rib fat thickness (RBFT), eye muscle area (EMA), intramuscular fat content (IMF), carcass weight (CW), carcass conformation (CC), carcass fatness (CF), adjusted weaning weight (AWW) and adjusted yearling weight (AYW) in the Czech Aberdeen 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.
