Abstract excerpt
Ultrasound measurements by trained and accredited sonographers on 9,232 Angus, Hereford, and Polled Hereford cattle at an average age of 450 d were used to estimate genetic and environmental (co)variances for weight at scanning (Wt), longissimus muscle area (LMA), longissimus muscle area adjusted to a constant weight of 400 kg (LMAawt), and fat depths at the rump and 12/13 rib sites.
