Final LW and in vivo carcass quality traits (Rib Eye Area-REA; Back Fat Thickness-BFT; Rump Fat Thickness - P8; Intramuscular Fat - IMF) were not affected by treatments (P<0.05). Slaughter weight was affected (P<0.05) by treatments (T4 ? T5 ? T2 = T1 ? T3). Treatments did not affect (P>0.05) Hot Carcass Weight (HCW), Chilled Carcass Weight (CCW), Pistola Cut (PC), main cuts (tender and strip loin, rump) nor morphometric measurements. Even though supplementing at a 0.5%LW rate allows higher daily LW gains, no differences were detected on carcass quality traits. aCARNE aSUPLEMENTACION aANIMAL PERFORMANCE aCARCASS TRAITS aSUPPLEMENTATION aTEERS1 aCAZZULI, F.1 aDEL CAMPO, M.1 aMONTOSSI, F.
