Bilateral opening in the nasal bones of goats in Nigeria

ABSTRACT

The present study was performed to observe the morphological details of the skulls of the major goat breeds in Nigeria involving 28 Red Sokoto, 24 Sahel and 12 West African Dwarf goats. The study revealed the presence of a bilateral opening in the nasal bones of the skulls. This unique occurrence appeared in about 70 of the Red Sokoto, less than 10 of the West African Dwarf and did not occur in the Sahel goat skulls. It was suggested that the structure which displayed a high level of breed specificity may be contributing to the weakness of the nasal area of the face. This finding to the best of our knowledge is rarely described in the literature and will be important in breed identification of goats and can contribute to the migratory history of the species.
