Özet
Bu araştırmada Ankara şartlarında Akkaraman, İvesi ve Kıvırcık koyunlarda döl verimi, kuzularda yaşama gücü ve büyüme özellikleri incelenmiştir. Araştırmada 42 Akkaraman, 28 İvesi ve 25 Kıvırcık koyun ve bunların kuzuları kullanılmıştır. Akkaraman, İvesi ve Kıvırcık koyunlarda doğum oranı ve bir doğuma kuzu sayısı sırasıyla % 85.71, 85.71 ve 80.00; 1.19, 1.13 ve 1.10 olmuştur. Akkaraman, İvesi ve Kıvırcık kuzularda sütten kesimde (90. gün) yaşama gücü sırasıyla % 97.67, 88.89 ve 90.91 bulunmuştur. Kuzularda doğum, sütten kesim ve 180. gün canlı ağırlıklara ait en küçük kareler ortalamaları aynı genotip sırasıyla 4.50, 4.40 ve 4.34 kg (P>0.05); 25.85, 25.19 ve 23.79 kg (P>0.05); 37.88, 36.65 ve 33.86 kg (P<0.01) olarak tespit edilmiştir. Sonuç olarak Ankara şartlarında yetiştirilen Akkaraman, İvesi ve Kıvırcık koyunlarda döl verimi ve kuzularda yaşama gücü bakımından ırkların genel olarak benzer olduğu; Kıvırcık kuzularda büyüme performansının Akkaraman ve İvesi kuzulardan daha düşük olduğu görülmüştür.
The current study was carried out to investigate the reproduction, survival rate and growth characteristics of Akkaraman, Awassi and Kıvırcık sheep breeds in Ankara, in central Anatolia, conditions. Akkaraman sheep breed is reared in central Anatolia while Awassi and Kıvırcık sheep breeds are reared at southeastern and western regions of Turkey, respectively. In the study, 42 Akkaraman, 28 Awasssi and 25 Kıvırcık ewes and those of lambs were used as animal material. The means of fertility results of Akkaraman, Awassi and Kıvırcık ewes were determined to be 85.71, 85.72 and 80.00 % for birth rates; 1.19, 1.13 and 1.10 for litter size, respectively. The survival rates of Akkaraman, Awassi and Kıvırcık lambs at weaning $(90^{th}$ days) 97.67, 88.89 and 90.91%, respectively. The least squares means obtained for Akkaraman, Awassi and Kivircik lambs were 4.50, 4.40 and 4.34 kg (P>0.05) for birth weight; 25.85, 25.19 and 23.79 kg (P>0.05) for weaning weight; 37.88,36.65 and 33.86 kg (P<0.01) for 180-day weight, respectively. The result of the study showed that reproduction traits and survival rate were similar among breeds while growth performance of Akkaraman and Awassi lambs was better than Kivircik lambs in Ankara, in Central Anatolia, conditions.
