The correlation noted between the facial indexes
and the angles of the face width (Zy.r-Tr-Zy.l), interlabial (Sn-Ls/Li-Sm) angles, and the zygomatic and the mandibular width (Go.r -Gn-Go.l) angles means that the shape of the face is much more related to these factors (Figures 3-5, Table 6).

The mean facial length, facial width and facial index
were 11.53 [+ or -] 0.08 cm, 9.30 [+ or -] 0.015 cm and 80.67 [+ or -] 0.44 cm, respectively; whereas the facial index
was 85.44 [+ or -] 1.89 cm in Mehraban sheep (Karimi et al.) and 138.48 [+ or -] 0.57 cm in Kagani goat (Sarma).
Based on the mean value of the total facial index (Table I) the treated male entities with TFI=90.38 (variation 74.31-115.6) belonged to the leptoprosop facial type, and the females with TFI=90.27 (variation 77.6-109.01) belonged to hyperleptoprosop facial type.
Based on analysis of the results and discussion of this research, the following conclusions can be made: According to sex, the two treated groups show statistically significant differences in mean values of all measured cephalofacial variables, excepting the total facial index.
Of the 71 skulls used, it was not possible to determine the volume of the left fossa in one; in another, upper facial index cannot be determined.
