Journal Title: Mehmet Akif Ersoy Üniversitesi Sağlık Bilimleri Enstitüsü Dergisi - Year 2018, Vol 6, Issue 2
Abstract
This research was intended to determine the fattening performance and carcass characteristics of Akkaraman male lambs fattened under traditional system and intensive fattening system. Each treatment groups (traditional system I, control, traditional system II) contained 20 Akkaraman male lambs and experiment lasted 70 days. Initial and 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 system II, respectively. Daily weight gains were 0.190, 0.220, 0.200 kg, and amounts of forage and concentrate feed consumed per 1 kg weight gain were 4.995, 5.045, 3.715 kg; and 4.165, 4.436, 5.710 kg for traditional system I, control, traditional system II, respectively. Amounts of daily concentrate and forage consumption were 0.999, 1.110, 0.743 kg; and 0.833, 0.976, 1.142 kg for traditional system I, control, traditional system II, respectively. Hot carcass, 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 from experiment 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 in carcass, 8.03, 8.49, 8.62 % for fat in tail, 0.63, 0.37, 0.35 % (P<0.01) for fat on kidney, 0.52, 0.41, 0.59 for internal fat, 27.00, 26.84, 27,41 % for leg, 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. In conclusion, even though traditional sheep raisers claimed that they fatten very well, it was observed that nutrient requirement of animal was not met under traditional fattening system. Fattening period lasted long because adaptation period to concentrate feed was very long. Control group performed better compared with other groups.
