Abstract
Hasak melez koyun tipinde ( % 31.25 Hampshire Down + % 31.25 Alman Siyah Baş + % 37.50 Akkaraman) neurocranium’un makro-anatomik olarak incelenmesi ve diğer evcil ve yabani koyunlarla arasındaki benzerlik ve farklılıkların tespit edilmesi amaçlandı. Araştırmada cinsiyet ayrımı gözetmeksizin 10 adet Hasak koyun tipi kullanıldı. Kafalar, vücuttan ayrıldıktan sonra her bir kafatası kemiği suda kaynatıldı. Kafatası örnekleri baştan yumuşak doku uzaklaştırılarak hazırlandı. İnceleme çıplak gözle yapıldı ve Sony marka digital fotoğraf makinasıyla fotoğrafları alındı. Neurocranium, os occipitale, os sphenoidale, os pterygoideum, os ethmoidale, vomer, os temporale, os parietale ve os frontale’den oluşmaktaydı. Hasak koyun tipinde tuberculum musculare’nin tam ortası düzeyinde longitudinal bir sulcus yapısı gözlendi. Os occipitale’nin squama occipitalis’i düzeyinde bir crista occipitalis externa tespit edildi. Fossa conylaris ventralis, fossa condylaris dorsalis’e göre daha derin ve belirgindi. Proc. pteryogoideus hafifçe lateral yönlü bir kıvrım oluşturmaktaydı. Fossa mandibularis sığ bir oluk şeklindeydi. Os parietale, planum parietale ve planum temporale’den oluşmuştu. Crista tentorica keskindi ve yay tarzında bir şekle sahipti. Hasak koyununun boynuzsuz olduğu ve yabani koyunlardaki boynuz çıkıntısının bulunduğu bölgede bir fossa yapısının bulunduğu gözlendi. Yeni bir tip olan Hasak melez koyununda herhangi bir makro-anatomik çalışma mevcut olmadığından bu çalışmanın gelecek araştırmalara kaynak teşkil etmesi beklenmektedir
It was aimed to investigate the macroanatomical structure of the neurocranium of Hasak crossbreed sheep (31.25% Hampshire Down + 31.25% German Black Headed Mutton + 37.50% Akkaraman) and to be determined of similarities and differences between other domestic and wild sheep. A total of 10 Hasak crossbreed sheep type were used without sexual distinction. After the heads were separated from the body, each head was boiled in water. The skull samples were prepared by removing the soft tissues from the head. The inspection was performed with the naked eye; and the pictures of the samples were taken by using a Sony Digital Camera. The neurocranium has consisted of os occipitale, os sphenoidale, os pterygoideum, os ethmoidale, vomer, os temporale, os parietale and os frontale. A longitudinal sulcus was observed in the middle of the tuberculum musculare in Hasak crossbreed sheep type. Crista occipitalis externa was determined on squama occipitalis of os occipitale. Fossa condylaris ventralis was more deep and evident than fossa condylaris dorsalis. Proc. pterygoideus had a curl toward to the lateral. Fossa mandibularis was in shaped of a shallow groove. Os parietale consisted of planum parietale and planum temporale. Crista tentorica was sharp and had a shape in the style of bow. Hasak sheep was hornless and the structure of a fossa was observed in the area where horn bulge in wild sheep. Because of there is not any macro-anatomical study about Hasak which is a new hybrid sheep type, this study has been expected to constitute a resource for future research.
