After, this ewes were fed until birth with 6 different rations (containing different nutrients levels) according to daily nutrient requirement of NRC (100%), below (80%) or above (120%) as groups during the last 6 weeks of pregnancy.Results: In the study, the differences between live weights and body condition scores of ewes before birth were significant (P0.05).Conclusion: As a result, it can be said that feeding of Konya Merino ewes during the last 6 weeks of pregnancy with ration about 80% of the level of daily nutrient requirements recommended by NRC may be sufficient for optimal growth of lambs until weaning.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:Aim: The aim of the present study was to examine the effect of feeding with ratios containing different nutrient levels of single or twin pregnant ewes during the last gestation on the live weights (LW), body conditions of Konya Merino ewes and growth and survival rate of lambs until weaning.Materials and Methods: For this aim, first, 120 ewes were synchronized with hormone at mating season (September) and mated.
📊
Key Findings & Data:After pregnancy statuses of ewes were determined via ultrasound imaging, 54 single and 54 twin pregnant ewes were separated 6 subgroups (3 singles, 3 twins).

Abstract

Aim: The aim of the present study was to examine the effect of feeding with ratios containing different nutrient levels of single or twin pregnant ewes during the last gestation on the live weights (LW), body conditions of Konya Merino ewes and growth and survival rate of lambs until weaning.Materials and Methods: For this aim, first, 120 ewes were synchronized with hormone at mating season (September) and mated. After pregnancy statuses of ewes were determined via ultrasound imaging, 54 single and 54 twin pregnant ewes were separated 6 subgroups (3 singles, 3 twins). After, this ewes were fed until birth with 6 different rations (containing different nutrients levels) according to daily nutrient requirement of NRC (100%), below (80%) or above (120%) as groups during the last 6 weeks of pregnancy.Results: In the study, the differences between live weights and body condition scores of ewes before birth were significant (P0.05).Conclusion: As a result, it can be said that feeding of Konya Merino ewes during the last 6 weeks of pregnancy with ration about 80% of the level of daily nutrient requirements recommended by NRC may be sufficient for optimal growth of lambs until weaning.

Özet

Amaç: Bu çalışmanın amacı, tekli ve ikiz gebe Konya Merinosu koyunları gebeliğin son döneminde farklı seviyede besin maddesi içeren rasyonlarla beslemenin, koyunların doğum öncesi canlı ağırlıkları ve vücut kondüsyonları ile kuzuların sütten kesime (75. gün) kadar olan büyüme ve yaşama güçleri üzerine etkisini araştırmaktır.Gereç ve Yöntem: Aşım sezonunda (Eylül) 120 baş koyuna östrüs senkronizasyonu uygulanarak doğal aşım yapıldı. Doğal aşım yaptırılan koyunların gebelik muayeneleri real-time ultrasonla yapılarak tekli ve ikiz gebe koyunlar belirlendi. Gebeliğin son 6 haftasında 54 baş tek ve 54 baş ikiz fetüs taşıyan koyunlar 6 alt gruba (3 tekli, 3 ikiz) ayrıldı. Daha sonra bu koyunlar doğuma kadar NRC (1985)'in tavsiye ettiği günlük besin madde ihtiyaçlarına yakın (%100), bunun altında (%80) ve üstünde (%120) besin maddesi ihtiva eden 6 farklı rasyonla gruplar halinde beslendi.Bulgular: Araştırmada, gebeliğin son döneminde farklı seviyede rasyonlarla beslenen koyunların doğum öncesi canlı ağırlıkları ve vücut kondüsyon puanları arasındaki fark önemli bulundu (P0.05) oldu.Öneri: Sonuç olarak, tekli ve ikiz gebe Konya Merinosu koyunları gebeliğin son 6 haftalık döneminde NRC (1985)'in tavsiye ettiği günlük besin maddesi ihtiyaçlarının yaklaşık %80'i seviyesinde beslemenin, sütten kesime kadar kuzuların optimum seviyede büyümeleri için yeterli olacağı kanısına varıldı.
