Ultrasound measures are also incorporated into this trait and have been shown to be highly correlated with the performance of slaughter progeny. Bulls are more masculine than cows in this respect; often having additional muscle mass in the shoulders, neck, and hindquarters than in cows, but this muscle mass is often less defined in Hereford cattle than in Continental breeds. Ultrasound measurements are also incorporated into this trait and have been shown to be highly correlated with the performance of slaughter progeny.
