Holştayn Sütçü İneklerde Buzağılamadan Önceki Vücut Kondisyon Skorunun Seçilen Döl Verimi Özellikleri Üzerine Etkisi

Sunulan çalışmada, sağlıklı Holştayn sütçü ineklerde reprodüktif performans ve buzağılama civarındaki vücut kondisyon skoru (VKS) arasındaki ilişki araştırıldı. Vücut kondisyonu, 0.25 puan aralıklı 5'lik ölçü sistemine göre değerlendirildi. Seçilen döl verimi özellikleri üzerine VKS'nin etkisini belirlemek için, inekler antepartum dönemdeki VKS'leri dikkate alınarak Grup 1 (VKS =4; n=23) olarak üç gruba ayrıldı. Buzağılama-ilk tohumlama aralığı ve servis periyodu bakımından gruplar arasında önemli farklılıklar gözlendi. Grup 2'deki ineklerde buzağılama-ilk tohumlama aralığı ile servis periyodu 1. ve 3. Gruptaki ineklerden daha kısaydı (P

Effect of Body Condition Score Before Calving on Selected Reproductive Traits in Holstein Dairy Cows

In the present study, it was investigated the relationship between reproductive performance and body condition score (BCS) around calving in healthy Holstein dairy cows. Body condition was assessed according to the 5-point BCS system with 0.25 unite increments. To determine the effect of BCS on selected reproductive triats, cows were divided into three groups based on their BCS in antepartum period; Group 1 (BCS =4; n=23). Significant differences between the groups were observed considering calving to first insemination interval and service period. The calving to first insemination interval and the service period were shorterfor the cows in Group 2 than for the cows in Group 1 and Group 3 (P < 0.05). The pregnancy rate at in the first insemination for the cows in Group 2 was 1.4 and 1.8 fold higher than the cows in Group 1 and Group 3, respectively. The highest reproductive performance was achieved in cows with body condition ranging between 3.5 and 3.75. Therefore, it was concluded that the reasonable BCS at near calving around calving for Holstein cows were 3.5-3.75 body condition.
