Abstract
Bu çalışmada 102 baş yerli ırk Akkaraman ve 60 baş melez Bafra koyunların üreme özellikleri ile kuzularının büyüme performansının değerlendirilmesi amaçlanmıştır. Akkaraman ve Bafra koyunlarında kuzulama oranları sırasıyla %85.29 ve %66.67 (P<0.01), doğuran koyuna göre kuzu verimi 1.31 ve 1.75 kuzu (P<0.01), kuzuların 90 günlük (sütten kesim yaşı) toplam canlı ağırlığı 46.65 kg ve 45.52 kg (P>0.05) ve sütten kesim yaşında yaşama gücü oranı %99.1 ve %91.4 (P<0.05) olarak bulunmuştur. Akkaraman ve Bafra kuzuların doğum ağırlığı, 1. ay, 2. ay ve 3. aydaki ortalama canlı ağırlıkları sırasıyla 4.98; 3.72 kg, 8.09; 7.88 kg, 25.12; 19,52 kg ve 35.00; 24.14 kg'dır. Genotipin doğum ağırlığı, 60. ve 90. gün canlı ağırlıkları üzerine etkisi önemli (P<0.05), ancak 30. gün canlı ağırlığına etkisi önemsiz bulunmamıştır (P>0.05). Akkaraman ve Bafra kuzularından 30, 60 ve 90. günlerde alınan cidago yüksekliği, vücut uzunluğu, incik çevresi, göğüs çevresi, göğüs derinliği, kulak uzunluğu, kulak genişliği, sağrı yüksekliği ve sağrı çevresi ölçüleri arasındaki farklılıklar istatistiksel olarak önemli bulunmuştur.
This study was aimed to evaluate the reproductive characteristics and growth performance of 102 heads of local Akkaraman ewes and 60 heads of crossbred (Chios x Karayaka B1) Bafra genotype. Akkaraman and Bafra ewes were found as lambing rates 85.29% and 66.67% (P<0.01), litter size 1.31 and 1.75 lambs (P<0.01), total body weight at 90 days (weaning age) of lambs 46.65 kg and 45.52 kg (P>0.05) and survival rate at weaning age 99.1% and 91.4% (P<0.05), respectively. Average birth weight, live weights at 30, 60 and 90 days of Akkaraman vs Bafra lambs were 4.98; 3.72 kg, 8.09; 7.88 kg, 25.12; 19.52 kg and 35.00; 24.14 kg, respectively, in which genotype was significant (P<0.05) in the birth, 60 and 90 days live weight but was not statistically significant (P>0.05) in the 30 days live weight. The differences in body height, body length, cannon circumference, chest circumference, chest depth, ear length, ear width, rump height, rump circumference measurements were found statistically significant in Akkaraman and Bafra lambs at 30, 60 and 90 days.
