The present research evaluated the productive response, carcass traits, and meat quality of sheep fed with increasing levels of crushed dry fruits of Acacia farnesiana (CDFAf). Thirty-two sheep (20 ± 2.5 kg and age 70 ± 15 d) were used. Four levels of CDFAf (T0=0.0, T1=1.5, T2=3.0, and T3=4.5 %) were evaluated. The stages of growing (21 d) and finishing (49 d) were assessed. Initial and final live weight (ILW and FLW), dry matter intake (DMI), daily and total weight gain (DWG and TWG), and feed efficiency (FE) were measured. On d 70, the animals were slaughtered to determine carcass traits (CaT), carcass morphometry (CaM), primal cut weight (PrCW), viscera weights (ViW), and meat quality parameters (MeQ). The addition of CDFAf did not affect the DMI; it positively affected DWG and TWG in the growing stage (P<0.05). No differences (P>0.05) were found in the productive variables during the finishing stage. The PrCWs differed (P<0.05), with T1 and T3 registering the highest weights in the loin and neck, respectively. The MeQ shows significant differences in the shear force and water retention capacity at 24 and 72 h. Better tenderness in the meat was observed in T1, and a greater loss of water and greater shear force was observed in T3. It is concluded that CDFAf improves weight gain and yield of primal cuts.
