This research was intended to determine the fattening performance andcarcass characteristics of Akkaraman male lambs fattened under traditionalsystem and intensive fattening system. Each treatment groups (traditional system I, control, traditional systemII) contained 20 Akkaraman male lambs and experiment lasted 70 days. Initialand final body weights of lambs were 32.47, 38.07, 37.73; 46.08,53.26, 46.87 kg for traditional system I, control, traditional systemII, respectively. Daily weight gains were 0.190, 0.220, 0.200 kg, andamounts of forage and concentrate feed consumed per 1 kg weight gainwere  4.995, 5.045, 3.715 kg; and4.165, 4.436, 5.710 kg for traditional system I, control, traditionalsystem II, respectively. Amounts of daily concentrate and forage consumptionwere 0.999, 1.110, 0.743 kg; and 0.833, 0.976, 1.142 kg fortraditional system I, control, traditional system II, respectively. Hotcarcass, cold carcass weights and dressing percentages were 22.18,24.68, 22.77 kg (P<0.05); 21.72, 24.18, 22.32 kg (P<0.05);and 0.48, 0.50, 0.50 % (P<0.05) for traditional system I, control,traditional system II, respectively. Some carcass characteristics obtained fromexperiment were as follows; 51.34, 52.44, 52.56 % for meat in carcass, 14.19,13.85, 13.26 % for fat in whole carcass, 19.74, 18.26, 18.69 % for bone incarcass,  8.03, 8.49, 8.62 % for fat in tail, 0.63, 0.37, 0.35 % (P<0.01) forfat on kidney, 0.52, 0.41, 0.59 for internal fat, 27.00, 26.84, 27,41 % forleg, 15.99, 15.69, 15.92 % for foreleg, 4.91, 4.88, 5.09 % for back, 4.85,5.37, 4.87 % for loin, 24.68, 24.66, 24.21 for others, respectively. Inconclusion, even though traditional sheep raisers claimed that they fatten verywell, it was observed that nutrient requirement of animal was not met undertraditional fattening system. Fattening period lasted long because adaptationperiod to concentrate feed was very long. Control group performed bettercompared with other groups.
