Özet:

 The objective of study was to determine the fattening performance and carcass characteristics of Akkaraman and Assaf x Akkaraman ASF x AK F1 crossbred male lambs obtained by crossing Assaf rams with Akkaraman ewes under breeding conditions. While the initial live weights of Akkaraman and ASF x AK F1 crossbred lambs were 23.89 kg and 23.77 kg, their final live weights were 41.02 kg and 44.03 kg p0.01, respectively. In 70 days of intensive fattening, purebred and crossbred lambs gained 17.14 kg and 20.26 kg total live weight, respectively. The feed intake of both groups for 1 kg live weight gain was 4.70 kg and 4.15 kg, respectively. Crossbred F1 lambs had significantly greater withers height p0.01 and body length p0.01 than Akkaraman lambs at all stages of fattening. At finishing, ASF x AK F1 lambs had the highest body length, larger chest, and leg circumferences than Akkaraman lambs. Among the slaughter and carcass characteristics of Akkaraman and ASF x AK F1 lambs, slaughter weight, cold carcass weight, untailed cold carcass weight, left half carcass weight, dressing percentage and the area of Musculus longissimus dorsi were determined to be 39.22 kg and 44.34 kg p0.05, 19.60 kg and 21.40 kg p0.05, 15.86 kg and 19.22 kg p0.01, 7.20 kg and 9.41 kg p0.001, 50.04 and 48.28, 12.49 cm2 and 14.24 cm2, respectively. Crossbred F1 lambs had statistically significantly higher values for head, foot, skin, testes and kidneypelvic fat weights than pure lambs. The tail weights of purebred and crossbred F1 lambs were determined to be 3.74 and 2.18 kg, respectively p0.001. The crossbred F1 lambs were found to have a higher leg weight 3.48 kg vs. 2.92 kg, p0.01, forearm weight 1.80 kg vs. 1.44 kg, p0.01, and flank-chest weight 1.39 kg vs. 0.92 kg, p0.01 compared to Akkaraman lambs. As a result, ASF x AK F1 crossbred lambs were found to have better fattening performance, slaughter and carcass characteristics than Akkaraman lambs.

 Çalışmanın amacı, Asaf koçları ile Akkaraman koyunlarının yetiştirici koşullarında melezlenmesi ile elde edilen Akkaraman ve Asaf x Akkaraman ASF x AK F1 melezi erkek kuzuların besi performansı ve karkas özelliklerini belirlemektir. Akkaraman ve ASF x AK F1 melez kuzuların besi başı canlı ağırlıkları sırasıyla 23.89 kg ve 23.77 kg, besi sonu canlı ağırlıkları ise sırasıyla 41.02 kg ve 44.03 kg olarak bulunmuştur p0.01. Yetmiş günlük entansif besi sonunda saf ve melez kuzular sırasıyla 17.14 kg ve 20.26 kg toplam canlı ağırlık kazanmışlardır. Her iki grubun 1 kg canlı ağırlık artışı için yem tüketimi sırasıyla 4.70 kg ve 4.15 kg olarak belirlenmiştir. Melez F1 kuzuların, besi döneminin tüm aşamalarında cidago yüksekliği p0.01 ve vücut uzunluğu p0.01, Akkaraman kuzularına kıyasla önemli derecede daha yüksek bulunmuştur. Besi sonunda ASF x AK F1 kuzuları, Akkaraman kuzulara göre daha yüksek vücut uzunluğuna, daha büyük göğüs ve but çevrelerine sahip olmuştur. Akkaraman ve ASF x AK F1 kuzuların kesim ve karkas özelliklerinden kesimhane ağırlığı, soğuk karkas ağırlığı, kuyruksuz soğuk karkas ağırlığı, sol yarım karkas ağırlığı, karkas randımanı ve Musculus longissimus dorsi alanı sırasıyla 39.22 kg ve 44.34 kg p0.05, 19.60 kg ve 21.40 kg p0.05, 15.86 kg ve 19.22 kg p0.01, 7.20 kg ve 9.41 kg p0.001, 50.04 ve 48.28, 12.49 cm2 ve 14.24 cm2 olarak belirlenmiştir. Melez F1 kuzular, baş, ayak, post, testis ve böbrekleğen yağ ağırlıkları bakımından Akkaraman kuzulardan istatistiksel olarak önemli derecede daha yüksek değerlere sahip olmuştur. Saf ve melez F1 kuzuların kuyruk ağırlığı sırasıyla 3.74 ve 2.18 kg olarak belirlenmiştir p0.001. Melez F1 kuzular, Akkaraman kuzulara kıyasla daha yüksek but ağırlığına 3.48 kg ve 2.92 kg, p0.01, ön kol ağırlığına 1.80 kg ve 1.44 kg, p0.01 ve etek ağırlığına 1.39 kg ve 0.92 kg, p0.01 sahip olmuştur. Sonuç olarak, ASF x AK F1 melezi kuzuların Akkaraman kuzulara göre daha iyi besi performansı, kesim ve karkas özelliklerine sahip olduğu tespit edilmiştir.
