Contenido: | The objective of this study was to evaluate the effect of different types of supplements on the performance of yearling steers grazing an annual forage crop (Sorghum bicolor L. moench) and its subsequent influence on carcass quality traits. 50 Hereford steers (265.3 kg live weight - LW) of 15 months of age grazing at a 7.5 steers/ha stoking rate were randomly allotted to 5 treatments (T): T1 - no supplement; T2 - soy expeller; T3 - sunflower expeller; T4 - rice bran; T5 - maize (T2 to T5 had a 0.5%LW supplementation rate). 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.
