Özet:

 This study was conducted to examine some reproductive characteristics for Ile de France sheep and pre-weaning growth of their lambs in intensive conditions. In this research, 233 head two-year-old Ile de France sheep and 209 lambs born from them were used as animal material. Some fertility characteristics pregnancy rate, infertility rate, abortion rate, stillbirth rate, birth rate, single birth rate, twin birth rate and litter size of Ile de France sheep and pre-weaning growth characteristics of lambs birth weight, live weight and daily live weight gain were examined. Pregnancy rate, infertility rate, abortion rate, stillbirth and birth rate were determined 76.82, 23.18, 3.91, 1.68 and 72.53, respectively in intensively reared Ile de France sheep. The litter size was calculated 1.24 in this study. It was found to the least squares means of birth weight, 30th day, 60th day, 90th day live weight and daily live weight gain of Ile de France lambs were 4.93, 10.01, 17.32, 27.80 kg and 212.20 grams, respectively. The effect of birth type was found to be significant p0.05; p0.001 on the characteristics examined. As a result, it can be said that some fertility parameters of Ile de France sheep need to be improved and the birth weight of the lambs is at a good level. Considering the twinning rate of the ewes and the litter size, it was concluded that the reproductive performance of the herd may increase in the following production seasons.

 Bu çalışma entansif koşullarda yetiştirilen Ile de France koyunlarda bazı dölverimi özellikleri ile kuzularında sütten kesim öncesi büyümenin incelenmesi amacıyla yapılmıştır. Araştırmada hayvan materyali olarak iki yaşlı 233 baş Ile de France koyun ve bunlardan doğan 209 baş kuzu kullanılmıştır. Ile de France koyunların bazı dölverim özellikleri gebelik oranı, kısırlık oranı, Abort oranı, ölü doğum oranı, doğum oranı, tek doğum oranı, ikiz doğum oranı ve doğuran koyun başına düşen kuzu sayısı ile kuzularının sütten kesim öncesi büyüme özelliklerinden doğum ağırlığı, canlı ağırlık ve günlük canlı ağırlık artışı incelenmiştir. Entansif olarak yetiştirilen Ile de France koyunlarda gebelik oranı, kısırlık oranı, abort oranı, ölü doğum oranı ve doğum oranı sırasıyla; 76,82; 23,18; 3,91; 1,68 ve 72,53 olarak tespit edilmiştir. Bu çalışmada doğuran koyun başına düşen kuzu sayısı 1,24 olarak hesaplanmıştır. Ile de France kuzuların doğum ağırlığı, 30. gün, 60. gün, 90.gün canlı ağırlık ve günlük canlı ağırlık artışı genel ortalamaları sırasıyla; 4,93; 10,01; 17,32; 27,80 kg ve 212,20 gram olarak bulunmuştur. İncelenen özelliklere doğum tipinin etkisi önemli p0,05; p0.001 bulunmuştur. Sonuç olarak Ile de France koyunların bazı dölverimi parametrelerinin iyileştirilmesi gerektiği, kuzularda doğum ağırlığının iyi seviyede olduğu söylenebilir. Ile de France koyunların ikizlik oranı ve doğuran koyun başına düşen kuzu sayısı dikkate alındığında sürü yönetiminin iyileştirilmesiyle dölverim performansının sonraki üretim sezonlarında yükselebileceği kanaatine varılmıştır.
