On Biometrical Aspects of the Cephalic Anatomy of Xisqueta Sheep (Catalunya, Spain)

This study, based on a 48 Xisqueta skull samples, gives a statistical insight of the skull shape in this breed. Thirty eight measurements and eight indexes were recorded. The variance structure was done using a Principal Component Analysis (PCA). This was possible sequel to the application and permi...

Thirty eight measurements and eight indexes were recorded. The variance structure was done using a Principal Component Analysis (PCA).

The mean length of the skulls was found to be 265.51±22.24 mm, with the width and cephalic index to the magnitude of 117.2 ± 6.89 mm and 44.69 ± 4.29 mm, respectively.
