The statistical analysis of some volumetric measurements in the Japanese quails' head with different feather color: A computed tomography study [Farkli{dotless} tüy renklerine sahip Japon bi{dotless}ldi{dotless}rci{dotless}nlari{dotless}ni{dotless}n başlari{dotless}nda bazi{dotless} hacimsel ölçülerin İstatistiksel analizi: Bilgisayarli{dotless} tomografi çali{dotless}şmasi{dotless}]

The aim of this study was to contribute to quail head morphology and the formation of basic data sources for comparative measurement in the quail head. in this study,60 japanese quail (coturnix japonica) heads,which were white,brown and wild type were used. four different anatomical structures of the quail heads,varying in feather color,were measured manually by two independent radiologists. these anatomical structures were head volume (hv),brain volume (bv),parietooccipital air space volume (poav) and calvarial bone volume (cbv). according to computed tomography (ct) measurements,the quail head with white feather color had the smallest volumetrical values. this condition is thought to be caused by genetic differences.
