Abstract

Kızgınlığı senkronize edilen Kıvırcık koyunlarında yaş, canlı ağırlık ve vücut kondisyon skorunun koyunların üreme parametreleri ve kuzuların gelişimi üzerindeki etkisi araştırılmıştır. Bu kapsamda yaş, vücut kondisyonu ve canlı ağırlığı farklı olan toplam 85 baş koyun değerlendirmeye alınmıştır. Ana yaşı, vücut kondisyon skoru (koç katım-doğum) ve canlı ağırlık (koç katım-doğum) ortalamaları sırasıyla 2.98, (3.04-3.22) ve (57.05-62.99) bulunmuştur. Ana yaşı ve vücut kondisyon skorunun kuzulama oranı, çoğuz doğum oranı ve yaşama gücü üzerine etkisi önemli bulunmuştur (P<0.05). Koç katım ve doğum dönemindeki canlı ağırlıkların çoğuz doğum oranı üzerine etkisi önemli bulunurken, yaşama gücü üzerine sadece doğum dönemindeki canlı ağırlık değerinin etkisi önemlidir (P<0.05). Ana yaşının doğum ağırlığı üzerine önemsiz, sütten kesim ağırlığı ve günlük canlı ağırlık artışı üzerine etkileri ise önemlidir (P<0.05). Anaların doğum dönemindeki canlı ağırlığının, kuzuların sütten kesim ve günlük canlı ağırlık artışı üzerindeki regresyon katsayısı önemlidir (P<0.05). Koyunların yaş, farklı dönemlerdeki canlı ağırlık ve vücut kondisyonun kendi aralarındaki korelasyon katsayısı değerlerinin (0.220-0.874) önemli olduğu saptanmıştır (P<0.05; P<0.01).

Abstract

The effects of age, live weight and body condition score on the reproductive parameters of the ewes and the development of the lambs were investigated in Kıvırcık ewes whose estrus was synchronized. In this context, a total of 85 sheep with different age, body condition and live weight were evaluated. The average dam age, body condition score (mating-birth) and live weight (mating-birth) were found to be 2.98, (3.04-3.22) and (57.05-62.99), respectively. The effect of dam age and body condition score on lambing rate, multiple birth rate and viability was found to be significant (P<0.05). While the effect of live weights during periods of mating season and birth on the multiple birth rate was found to be significant, only the effect of live weight during the birth period on survival rate was significant (P<0.05). While the effects of dam age on birth weight are insignificant, their effects on weaning weight and daily live weight gain are significant (P<0.05). The regression coefficient of the live weight of the dams at birth on the weaning and daily live weight gain of the lambs is significant (P<0.05). It was determined that the correlation coefficient values (0.220-0.874) between the age, live weight and body condition of the sheep in different periods were significant (P<0.05; P<0.01).
