Özet
Özet: Bu araştırma Akkaraman irki kuzularının; 35, 40, 45 ve 50 kg kesim ağırlıklarında besi performansı, kesim ve karkas Özelliklerini incelemek amacıyla yapılmıştır. Araştırmada 2.5-3 aylık yaşta, ortalama 21 kg ağırlığında sütten kesilmiş 1. Grupta (35 kg) 13, diğer üç grupta (40, 45 ve 50 kg) 14'er baş olmak üzere toplam 55 baş Akkaraman erkek kuzu kul- lanılmıştır. Kuzular planlanan kesim ağırlıklarına ulaşana kadar ad libitum kesif yem ve günlük 100 g/baş buğday samanı ile beslenmişlerdir. Istatistik analizler tek yönlü variyans analizi ile yapılmıştır. Gruplarda sırası ile beside geçen süre 70.31, 87 36, 108. 14 ve 134.07 gün; günlük ortalama canlı ağırlık artışı 199.74, 224.30, 225.34 ve 216.37 g: yemden yararlanma değerleri 6.17, 5.77, 6.12 ve 6.62 kg olarak bulunmuştur Araştırmada karkas, but, kol, sirt, bel ve diğerleri olmak üzere beş parçaya ayrılmış ve karkas kompozisyonunu araştırmak amacı ile kol diseke edilmiştir. Gruplarda sırası ile soğuk karkas agirliği 16.18, 18.18, 21.28 ve 25.72 kg: soğuk karkas randimani F.33, 46.02, 47.25 ve 51.58, karkasta but oran 30.14, 29 42, 28.26 ve 27 12: kol oranı %15.17, 14.57 14.12 ve 13.43, bel oranı %6.42, 6.70, 6.25 ve 6.79, kuyruk oranı 16.18, 15.60, 17.78 ve 21.41: MLD kesit alanı 12.35, 14.40, 14.52 ve 16.24c * m ^ 2 sirt yağı kalınlığı 2.88, 3.68, 3.90 ve 4.73 mm, kolda et oranı %65.07, 65.33, 64.09 ve 61.83, yağ oranı %14.33, 13.31, 15.62 ve 18.77; kemik oranı %20.60, 21.36, 20.29 ve 19.40 olarak bulunmuştur. Sonuç olarak; incelenen özellikler bakımından diğer kesim gruplarına göre 45 kg kesim ağırlığının en yüksek değerleri gösterdiği bulunmuştur.
Summary: This study was carried out to investigate the fattening performance and carcass traits of Akkaraman male lambs at slaughter weight of 35, 40, 45 and 50 kg. The material of the research consisted of 55 Akkaraman male lambs aging from 2.5 to 3 months old with an average body weight of 21 kg. During the experiments lambs were fed with wheat hay (100 g/head/day) and consantrates ad libitum. The data were analyzed by one-way analysis of variance (ANOVA) test. The period acquired for reaching live weights, average daily gains at the fattening period and feed/gain ratios were found as 70.31 day, 199.74 g and 6.17 kg for 35 kg: 87.36 day, 224.30 g and 5.77 kg for 40 kg: 108.14 day, 225.34 g and 6.12 kg for 45 kg: 134.07 day, 216.37 g and 6.62 kg for 50 kg, respectively. The carcasses were seperated into five major cuts including leg, shoulder, back, loin and others. To determine carcass composition, shoulder cuts were dissected. The cold carcass weight, dressing percentage, the ratios of leg, shoulder, loin and tail fat weights were found as 16.18 kg. 46.33% 30.14%, 15.17%, 6.42% and 16.18% for 35 kg: 18.18 kg, 46.02%, 29.42%, 14.57%, 6.70% and 15.60% for 40 kg 21.28 kg. 47.25%, 28.26%, 14. 12%, 6.25% and 17.78% for 45 kg: 25.72 kg, 51.58%, 27 12%, 13.43%, 6.79% and 21.41% for 50 kg respectively. The percentages of lean, fat and bone at shoulder cuts were found as 65.07%, 14.33% and 20.60% for 35 kg: 65.33%, 13.31% and 21.36% for 40 kg: 64.09%, 15.62% and 20.29% for 45 kg: 61.83%, 18.77% and 19.40% for 50 kg respectively. As a result, slaughter weight of 45 kg show the maximum values about the investigated characteristics than the other slaughters group was found.
