Özet
Bu çalışmada, İvesi koyunlarında farklı yaşta sütten kesimin, kuzularda gelişim özellikleri, analarda süt üretimi üzerine etkileri araştırılmıştır. Araştırmanın hayvan materyalini, Kilis ilinde özel bir işletmede bulunan İvesi koyunları ve kuzuları oluşturmuştur. Doğan kuzular cinsiyetleri de dikkate alınarak 35'er başlık 3 gruba ayrılmıştır. Birinci gruptaki kuzular 60. günde (I. grup), ikinci gruptaki kuzular 75. günde (II. grup), üçüncü gruptaki kuzular ise geleneksel olarak yapılan sürede (90. gün) sütten kesilmiştir (III. grup). Çalışma sonunda, ortalama doğum ağırlıkları I. grupta 3.4 ± 0.09 kg, 3.6 ± 0.08 kg, 3.4 ± 0.09 kg olarak tespit edilmiş olup, geleneksel yönteme göre (90 gün) erken yaşta sütten kesimin (60 gün) kuzuların gelişimi üzerine etkisinin olduğu (P<0.05) tespit edilmiştir. Fakat sütten kesimden itibaren yarı entansif şartlarda kuzu beslemenin işletme açısından ekonomik olmadığı belirlenmiştir.
In this study, the effects of different weaning ages on the developmental characteristics of lambs and milk production of ewes were investigated. The animal material of the study consisted of Awassi sheep and its lambs in a private farm in the Kilis province. Lambs were divided into three groups (35 heads) according to sex type. The first group was weaned at 60. days, second group was at 75. days, III. group was at 90. days. At the end of the study, average birth weights were determined as 3.4 ± 0.09 kg, 3.6 ± 0.08 kg and 3.4 ± 0.09 kg in the same group ranking and weaning weight was effected by early weaning age (60 days) according to the traditional method (90 days) (P <0.05). However, it was determined that lamb feeding under semi-intensive conditions after weaning was not economical in terms of farm.
