Kıvırcık koyunlarında stereolojik metotlacranial hacim hesaplanması ve bunun kraniyometrik ölçümleri ile ilişkisi

Bu çalışmada toplam 40 adet Kıvırcık koyunun (20 erkek, 20 dişi) kafatası kullanıldı. Bu amaçla kafataslarından 4adet morfometrik (canlı, karkas, kafa ve kafatası ağırlıkları) ve 23 craniometrik ölçüm alındı. Kafataslarından yapılanparalel kesitler kullanılarak nokta sayım tekniği ile cranial hacim hesaplanması yapıldı. Kıvırcık ırkı koyunlarda,cranial hacim dişiler için 133,89±10,82 cm3 , erkekler için ise 136,10±17,281 cm3olarak tespit edildi. Uygulanan noktasayım tekniği ile %1’den daha küçük bir hata katsayısı ile hesaplandı. Morfometrik verilerin hem dişi hem de erkekkoyunlar arasındaki farkın istatistiki olarak önem taşıdığı gözlenirken, cranial hacim değerleri arasındaki farkın önemliolmadığı belirlendi. Hem dişi hem de erkek koyunlarda tüm kafatasının genel değerlendirmesinde önem taşıyankafatasının uzunluk değerleri (M1, M2, M3) ile cranial hacim arasında P

Cranial volume estimation using stereological method in kivircik sheep andits correlations between skull parameters

We used 40 Kıvırcık breed sheep (20 male, 20 female) skulls in this study. We took 4 morphometric (body, carcas,head and skull weights) and 23 craniometric measurements from the skulls. Cranial volume estimation, using pointcounting technique on the paralel crosssections from the skulls was done. In Kıvırcık breed sheep, we determined thatcranial volume is 133.89±10.815 cm3for females and 136.10±17.281 cm3for males. The estimation using thestereological point counting technique gave us less than 1% coefficiency of error. The coefficient of error was less than5% for the stereological estimates using point counting technique. All the data were evaluated for sexual dimorphism.We observed that according to morfpohometric data the difference between males and females was statisticallysignificant. But the difference among cranial volume values was not significant. To observe the differences in cranialmorphology with more details and to be able to make comparisons in indices estimations made by different authors,we estimated our indices 6 different ways in this study. We observed statistically important correlastions betweencranial volume and the skull length values that are important in evaluation of whole skull (M1, M2, M3) in both maleand female sheep (P
