The objective of this study was to determine how real-time ultrasound (RTU) measurements would compare with carcass measurements to predict the percentage of lean from the four primals (PERL4P). Data were collected on market ready cattle (n=490). Traditional carcass measures collected were: (1) hot carcass weight (HCW); (2) 12–13th rib fat thickness (CFAT); (3) 12–13th rib ribeye area (CREA); and (4) percentage of kidney, pelvic, and heart fat (KPH).
