Abstract

BACKGROUND:There is no comprehension data on anatomical
indices of Nigerian goats. OBJECTIVES: To show osteometric
values of some cranial indices in Nigerian goats. METHODS:
Sixty (60) goat skulls that were found around Makurdi, Kwande,
Katsina-ala and the neighbouring Adamawa state of Nigeria,
were studied by investigating the 30 craniometric values.
RESULTS: The measured distance from the facial tuberosity to
the infraorbital foramen was 2.33±0.29 Cm and 1.80±0.14 Cm
for females and males, respectively. In addition, the distance
from the medial canthus to the supraorbital foramen was 27±0.31
Cm for females and 2.83±0.24 Cm for males; from the lateral
alveolar root to the mental foramen was 2.05±0.07 Cm for
females and 5.10±7.28 Cm for males; and from the mandibular
foramen to the ventral border of mandible was 5.90±0.14 Cm for
females and 5.48±0.43 Cm for males. CONCLUSIONS: This
breed of goat might be a different phenotype of the breeds that is
available in Nigeria.
