Abstract

Horses, used for various purposes for centuries, are today commonly used for sporting purposes. It is critical to identify the horses that are used in this way by using the coat color and markings on the horse. The animal material for this research consisted of 101 Arabs and 206 Thoroughbreds. The most common coat color was BAY (56.6%). The least common coat colors were BLACK (0.3%) and DUN (0.3%). The presence of head marks on horses rated 0, 1, 2, 3, 4, and 5, and the rate of presence of the head mark were 17.2%, 29.2%, 7.5%, 6.8%, 26.0%, and 13.3%, respectively. When examining leg markings, the most common mark was the half-stocking (16.9%) on the left back leg, while the stocking (1.3%) was the least frequent mark on the front right leg. According to the findings of the study, which was conducted to analyze the condition of Arab and Thoroughbred horses, bay was the most common coat color seen in horses in general. Consequently, this situation is due to the preferences of breeders and horse owners.

Arap ve İngiliz atlarında don rengi ve nişanelerin dağılımı

Abstract

Yüzyıllar boyunca çeşitli amaçlarla kullanılan atlar günümüzde daha çok sportif amaçla kullanılmaktadır. Bu şekilde kullanılan atların kimliklendirilmesi büyük önem taşımakta ve bunun için atların don rengi ile nişanelerinden faydalanılmaktadır. Bu araştırma Türkiye’de yetiştirilen 101 Arap ve 206 İngiliz olmak üzere toplam 307 yarış atında don ve nişanelerin dağılımı incelenmiştir. Genel olarak atlarda % 56,5 ile en çok DORU don rengi gözlemlenirken, en az BOZ (% 0,3) ve YAĞIZ (% 0,3) don renkleri görülmüştür. Atlara baş nişaneleri bulduğu bölgelere göre 0; 1; 2; 3; 4 ve 5 olarak puanlanmıştır. Buna göre baş nişanelerinin bulunma oranları sırasıyla % 17,2; % 29,2; % 7,5; % 6,8; % 26,0 ve % 13,3 olmuştur. Atlarda sekiler incelendiğinde % 16,9 ile en çok sol arka bacakta Yüksek Seki, en az ise sağ ön bacakta Çizme Seki (% 1,3) görülmüştür. Sonuç olarak atların soy kütüklerine kayıdedilmesinde önemli bir yeri olan Don rengi ve Nişanelerin, Arap ve İngiliz atlarındaki durumunun incelenmesi amaçlanan bu çalışmada atlarda en çok DORU don renginin görüldüğü belirlenmiştir. Bu durumun ise yetiştircilerin ve at sahiplerinin tercihlerinden ileri geldiği sonucuna varılmıştır.
