In this research, the fattening performance of Güney Karaman, Kangal-Akkaraman and Akkaraman ram lambs slaughtered at different (30,35 and 40 kg)live weights was determined. The material of the research consisted of 20 ram lambs at 2.5 to 3 months of age with the average body live weight of 23 kg for each group (total 60 ram lambs).During the experiments the lambs were fed with the concentrates ad libitum and restricted wheat hay (100 g/head/day). Daily weight gains for reaching 30, 35 and 40 kg body live weight were found to be 270.90, 275.42 and 278.12 g for Güney Karaman, 264.15, 285.66 and 310.16 g for Kangal-Akkaraman,and 271.00, 255.57 and 257.85 g for Akkaraman respectively.The periods for reaching 30,35 and 40 kg body live weight were found to be 26.75, 45.85 and 67.75 days,20.40, 36.33 and 49.83 days,24.95,48.28 and 67.57 days, the amounts of concentrates and hay consumed per kg of live weight gain 3.970 and 0.181, 4.295 and 0.194, 4.709 and 0.204 kg; 4.406 and 0.252, 4.531 and 0.234, 4.439 and 0.229 kg; 4.465 and 0.213, 5.043 and 0.206, 5.186 and 0.195 kg respectively.
