Amaç: Mevcut araştırmanın amacı buzağı ölümleri ile ilgili faktörlerin araştırılması amacı ile yapıldı. Gereç ve Yöntem: Merkez Sığır Yetiştiriciliği ve Süt Çiftliğinde (CCBDF) 16 yıl süresince kaydedilen buzağı ölümleri mevsim, yaş, cinsiyet, ırk ve etiyolojisine göre incelendi. Bulgular: Dişi buzağıların (%56.77) erkek buzağılardan (%43.23) daha çok öldüğü gözlendi. Egzotik ve melez ırklardaki ölüm oranı yerli ırklardan daha fazla olarak belirlendi. Bahar, yaz ve kış mevsimdeki ölüm oranı sırası ile %28.99, %33.03 ve %37.98 olarak belirlendi. Esas ölüm sebebi olarak solunum sistemi hastalıkları (%38.75), tüberküloz (%20.02) ve sindirim sistemi hastalıkları (%16.73) olarak tespit edildi. Diğer ölüm sebepleri ise malnutrusion (%5.28), zayıflık (%4.72), hairball (%3.12), babezioz (%2.56), iç kanama (%2.56), timpani (%2.24), yanıkara (%2.24) ve şap (%1.76) olarak belirlendi. Yaşın ise ölümle ilişkisinin olmadığı belirlendi. Öneri: Bir aylık buzağıların mortalite riskini yüksek oranda taşıdığı bildirilebilir.

Öz

Aim: The objective of this study was to find out the underlying causes and factors which are associated with calf mortality. Materials and Methods: The 16 year’s data of calf mortality in the Central Cattle Breeding and Dairy Farm (CCBDF) were analyzed for season, age, sex, breed and etiology. Results: Female calves (56.77%) died more than males (43.23%). The mortality was significantly higher in exotic and crossbred animals than in local/indigenous calves. Mortality rate were 28.99%, 33.03% and 37.98% in rainy, summer and winter season, respectively. The major causes of death were respiratory tract disease (38.75%), tuberculosis (20.02%) and alimentary tract infections (16.73%). The other causes of death in calves occurred in the following frequencies: Malnutrition (5.28%), debility (4.72%), hairball (3.12%), babesiosis (2.56%), internal haemorrhage (2.56%), tympanitis (2.24%), black quarter (2.24%) and foot and mouth disease (1.76%). Age is the most important factor and significantly associated with mortality. Conclusion: Calves of first month of life may have higher mortality risk
