This study was conducted to evaluate the use of ultrasound measurements to predict carcass composition of 115 steers (Nellore, ½ Angus x Nellore, ½ Simental x Nellore, and Canchim) with different frame sizes (small and large) and average initial body weight of 329 kg. After 120 days in a feedlot, animals were weighed followed by ultrasound measurements of rib eye area (RA) and fat thickness (FT). Animals were slaughtered and measurements of carcass RA and FT, weights of hindquarter, forequarter, […]
