The animals were slaughtered at 210 days of age, being determined the weight and measures of carcass, dressing percentage and commercial joints. There was no diet effect on the slaughter weight (SW), hot (HCW) and cold (CCW) carcass weights, hot (HCD) and cold (CCD) carcass dressing and percentage of cold loss (PCL).
