Özet:

 This study was carried out to determine the relationship between body condition score BCS determined at birth and early lactation first 100 days, lactation milk yield 305 days, the number of inseminations resulting in pregnancy, and birth and growth characteristics in Holstein pregnant heifers. In the study, 59 pregnant heifers 242 months old and 55 heads 30 and 25 calves born from these heifers were used. BCS values of heifers were determined at the time of birth using the BCS application and scored as 3.50 n18, 3.75 n31 and 4.00 n10. As a result of the study, the relationship between BCS values and calves weight and body length at birth was significant P0.05. The birth weight and body length of the calves obtained from cows with a BCS score of 3.75 and 4.00 were higher than those with a BCS score of 3.50. The effect of BCS on other features examined in the study was not significant. According to the results of this study, it is possible to say that BCS is one of the positive criteria in improving calf performance in the management and selection studies to be carried out in the enterprises. There is a need for similar studies using more animals in different enterprises, in order to reach more precise judgments.

 Bu çalışma Holstein ırkı gebe düvelerde doğumda belirlenen vücut kondisyon skoru VKS ile erken laktasyon ilk 100 gün, laktasyon süt verimi 305 gün, gebelikle sonuçlanan tohumlama sayısı ve buzağılarda doğum ve büyüme performansı özellikleri arasındaki ilişkiyi belirlemek amacıyla yapılmıştır. Çalışmada Holstein ırkı 59 baş gebe düve 242 aylık yaşta ve bu düvelerden doğan 55 baş 30 ve 25 buzağı kullanılmıştır. Düvelerin VKS değerleri doğumda ve VKS aplikasyon uygulaması kullanılarak belirlenmiştir. Gebe düvelerde VKS ler 3.50 n18, 3.75 n31 ve 4.00 n10 olmak üzere üç şekilde skorlanmıştır. Çalışmada VKS değerleri ile ineklerde erken laktasyon ve laktasyon süt verimi, gebelikle sonuçlanan tohumlama sayısı ve buzağıların büyüme performansı arasındaki ilişki önemli olmamış ancak VKS ile buzağılarda doğum ağırlığı P0.05 ve vücut uzunluğu P0.05 arasındaki ilişki önemli bulunmuştur. Doğumda VKS skoru 3.75 ve 4.00 olan ineklerden elde edilen buzağıların doğum ağırlığı ve vücut uzunluğu VKS skoru 3.50 olanlardan daha yüksek olmuştur. Bu çalışmanın sonuçlarına göre işletmelerde yapılacak yönetim ve seleksiyon çalışmalarında VKSnin buzağı performansını iyileştirmede olumlu kriterlerden biri olduğunu söylemek mümkündür. Daha kesin yargılara varabilmek için farklı işletmelerde daha fazla sayıda hayvan kullanılarak yapılacak benzer çalışmalara ihtiyaç vardır.
