The objective of this work was to estimate the correlations among measurements taken in vivo with ultrasound equipment with some carcass characteristics measured after slaughter. Twenty two Nellore steers, with average shrunk body weight of 279 kg and 24 months of age, were fed by 98 days with high concentrate diets. The shrunk body weight, the ribeye area (AOLU) and the fat thickness (EGSU) over the Longissimus dorsi muscle between 12ª and 13ª ribs, were measured at 28 days intervals. […]
