An anatomical and morphometrical study was undertaken on the external and internal nares of 26 Gaddi sheep at Palampur during 2013-15. The results of the study revealed that the nostrils were slit like in Gaddi sheep and situated obliquely at rostral most part of head. The mean length of the nostrils was 2.51±0.52 cm. The mean distance between the dorsal commissures and ventral commissures was 3.26±0.54 cm and 1.04±0.25 cm, respectively. Nasal cavity of sheep extended from external nares to the chonae. The nasal cavity in Gaddi Sheep was provided with the three nasal turbinate bones (choanae) viz. dorsal, ventral and middle. Length of the dorsal turbinates ranged from 10.70 cm to 12.80 cm in adult animal. The width of the dorsal turbinate had range from 1.90 to 2.70 cm with mean length of 2.36±0.40 cm. The length of the ventral nasal turbinate ranged from 9.90 to 12.20 cm, whereas its width was from 2.40 to 3.50 cm.

Abstract


An anatomical and morphometrical study was undertaken on the external and internal nares of 26 Gaddi sheep at Palampur during 2013-15. The results of the study revealed that the nostrils were slit like in Gaddi sheep and situated obliquely at rostral most part of head. The mean length of the nostrils was 2.51±0.52 cm. The mean distance between the dorsal commissures and ventral commissures was 3.26±0.54 cm and 1.04±0.25 cm, respectively. Nasal cavity of sheep extended from external nares to the chonae. The nasal cavity in Gaddi Sheep was provided with the three nasal turbinate bones (choanae) viz. dorsal, ventral and middle. Length of the dorsal turbinates ranged from 10.70 cm to 12.80 cm in adult animal. The width of the dorsal turbinate had range from 1.90 to 2.70 cm with mean length of 2.36±0.40 cm. The length of the ventral nasal turbinate ranged from 9.90 to 12.20 cm, whereas its width was from 2.40 to 3.50 cm.
