For this aim, 10 HF and 8 BS in the first and 7 HF and 10 SIM in the second group were used. The values of HF and BS bulls in the first group were determined 549.20±16.87 and 512.62±16.86 kg for final weight (FW), 1.34±0.05 and 1.35±0.06 kg for average daily gain (ADG), 52.51±0.59 and 54.40±0.66% for dressing percentage (DP), 279.44±3.28 and 289.40±3.69 kg for hot carcass weight (HCW), 66.82±2.83 and 82.76±3.17 cm 2 for rib eye area (REA), 0.23±0.03 and 0.29±0.03 cm for subcutaneous fat thickness (SFT), 5.92±0.02 and 5.94±0.02 for pH24, 25.10±1.77 and 25.87±1.98% for cooking loss (CL) and 40.21±7.64 and 53.54±8.55 N for shear force (SF). On the other hand, the averages of HF and SIM bulls in the second group were found 579.14±16.60 and 562.00±13.88 kg for FW, 1.57±0.05 and 1.62±0.04 kg for ADG, 53.47±0.72 and 54.29±0.60% for DP, 304.36±4.14 and 309.25±3.45 kg for HCW, 69.50±4.10 and 76.50±3.43 cm 2 for REA, 0.49±0.08 and 0.36±0.07 cm for SFT, 5.74±0.04 and 5.77±0.04 for pH24, 26.63±1.10 and 27.09±0.92% for CL and 40.89±4.56 and 60.67±3.81 N for SF. Under the same managerial and nutritional conditions, fattening performance of HF was similar to BS and SIM breeds, but DP and REA of BS were higher, and beef from SIM was firmer that those of HF. <div> </div>}, number={1}, publisher={Aydın Adnan Menderes Üniversitesi}
