Abstract

The aim of present study was to investigate the effects of Ovsynch synchronisation programme combined with vitamins and minerals upon biochemical, hormonal and reproductive parameters for improving post partum (pp) reproductive performance of underfed dairy cows. Thirty-six healthy cows, aged 3-10 years-old, were used with a minimum 43 days pp. Following the first blood sampling (as baseline), 25 days before synchronisation (GnRH injection), the body condition scores (BCSs, 1-5 scale) were determined. After balancing the BCSs (2.56, mean), animals were then divided into four trial groups, as control (Group I, n=7), vitamin ADE (II, n=10), mineral mix (III, n=9) and combination group (IV, n=10). Overall, the results suggest that; i) Ovsynch synchronisation programme, supplemented with vitamins and minerals, favourably affected the plasma levels of vitamin A only, ii) desirable effects of supplements upon the presence of luteal structure and ultimate pregnancy rate were evident in vitamin group only, iii) glucose (tendency) as well as some protein and lipid levels were progressively changed by negative energy balance (NEB), and iv) the low initial cyclic activity and poor BCS seemed to diminish the overall success rate of synchronisation programme used in underfed dairy cows early pp.

Özet

Sunulan çalışmada, yetersiz bakım-besleme koşulları altındaki sütçü ineklerde vitamin ve mineral uygulamalarıyla kombine edilen Ovsynch senkronizasyon programının biyokimyasal, hormonal ve reprodüktif parametreler üzerine etkilerinin postpartum (pp) reprodüktif performansın artırılmasındaki rolü araştırıldı. Yaşları 3-10 arasında değişen, doğumunun üzerinden en az 43 gün geçmiş, 36 baş sütçü inek kullanıldı. İlk kan örneklerinin (bazal seviye) alınmasından sonra, senkronizasyon (GnRH enjeksiyonu) öncesi 25. günde, vücut kondisyon skorları (VKS, 1-5 skalası) belirlendi. Ardından, hayvanlar VKS yönünden dengelendikten (ort. 2,56) sonra, kontrol (Grup I, n=7), vitamin ADE (II, n=10), mineral mix (III, n=9) ve kombine grup (IV, n=10) olmak üzere dört deney grubuna ayrıldı. Sonuç olarak, erken pp dönemindeki sütçü ineklerde; i) Ovsynch senkronizasyon programıyla birlikte kullanılan vitamin ve minerallerin, sadece plazma vitamin A düzeylerini olumlu yönde etkilediği, ii) anılan katkının, luteal yapı varlığı ve gebelik oranı üzerine istenilen etkilerinin sadece vitamin grubunda belli olduğu, iii) glikoz (nispeten), protein ve lipid düzeylerinin, çalışma boyunca negatif enerji balansına (NEB) bağlı olarak değiştiği, ve iv) başlangıçtaki düşük siklik aktivite ve zayıf VKS düzeylerinin, senkronizasyon programının genel başarı oranını azaltabildiği kanısına varıldı.
