Abstract

The objective of this study was to evaluate the out-of-season reproductive performance and lamb birth weight of Kangal ewes orally administered a bolus of vitamin and mineral premix or mineral premix given as injection with at 40-45 days postpartum during the anestrous period. In total, 78 primiparous Kangal ewes with were randomly allocated to three experimental groups. Estrus induction protocol was performed and a ram was introduced to the ewes at the 80th days postpartum. Ewes in the group 1 a dose of 2 mL of injectable mineral solution at 40-45 days before oestrous synchronisation, was administered at once (n = 25). As for group 2, at 40-45 days before oestrous synchronisation, a mineral bolus was given orally once (n = 27). To the ewes in the group 3 a dose of 2 mL of physiological saline was given once to the animals (n = 26) simultaneously with group 1 and group 2. Reproductive parameters such as estrus and pregnancy rates; single, twin, triplet, and multiple pregnancy rates; litter size; embryonic mortality; fecundity; and dystocia rates were evaluated. In addition, the placentas were weighed to evaluate the effect of mineral supplements on placentation. There were no significant differences between the groups in terms of parameters above (p>0.05). However, the rate of dystocia was significantly lower in group 2 compared to Groups 1 and 3 (p<0.05). In conclusion, as a result, it was determined that slow-releasing boluses could not produce efficacy during the throughout pregnancy.

Özet

Bu çalışmanın amacı, doğumdan sonraki 40-45 günde anöstrus döneminde oral olarak verilen bolus vitamin ve mineral premiks veya enjeksiyonluk olarak uygulanan mineral premiksin Kangal koyunlarının sezon dışı üreme performanslarını ve kuzu doğum ağırlıklarını değerlendirmektir. Toplamda 78 adet primipar Kangal koyunu rastgele üç grubuna ayrıldı. Hayvanlar senkronize edildi ve postpartum 80. günde koç katımı yapıldı. Grup 1'deki koyunlara östrus senkronizasyonundan 40-45 gün önce 2 mL enjekte edilebilir mineral solüsyonu tek doz olarak uygulandı (n=25). Grup 2'ye ise, östrus senkronizasyonundan 40-45 gün önce oral olarak bir kez mineral bolus verildi (n=27). Grup 3'teki koyunlara grup 1 ve grup 2 ile eş zamanlı olarak hayvanlara (n = 26) bir kez 2 mL fizyolojik tuzlu su verildi. Östrus oranları gibi üreme parametreleri; gebelik oranları; tek, ikiz, üçüz ve çoğul gebelik oranları; bir batında yavru sayısı; embriyonik ölüm; doğurganlık; ve güç doğum oranları değerlendirildi. Ek olarak, mineral takviyelerinin plasentasyon üzerindeki etkisini değerlendirmek için plasentalar tartıldı. Yukarıdaki parametreler açısından gruplar arasında anlamlı fark yoktu (p>0.05). Ancak, güç doğum oranı Grup 2'de Grup 1 ve Grup 3'e göre anlamlı olarak daha düşüktü (p<0.05). Sonuç olarak, uzun salınımlı bolusların tüm gebelik boyunca etkinlik oluşturamadığı belirlendi.
