title: Some aspects of the craniofacial indices and macro neurometrics of the Nigerian local pig (Sus scrofa).
abstract: This study is about the craniofacial indices and neuromorphometrics of the Nigerian local pig and has been performed on twelve males and fourteen females of ages one and a half to two years. The average values obtained for the tongue length, tongue weight, rasp length, left pinna length, right pinna length, left pinna width, right pinna width, height of left external nares, height of right external nares and the rima oris length were 17 +/- 1.3 cm, 90 +/- 16 g, 4.6 +/- 0.58 cm, 13 +/- 1.3 cm, 13 +/- 1.3 cm, 8.7 +/- 1.5 cm, 8.7 +/- 1.4 cm, 0.98 +/- 0.12 cm, 0.96 +/- 0.13 cm and 19.51 +/- 2.89 cm respectively, while the mean brain weight, mean brain length, cerebrum and cerebellum lengths, brain and cerebellar heights were 84 +/- 12 g, 6.9 +/- 1.5 cm, 4.9 +/- 1.7 cm, 2.2 +/- 1.0 cm, 5.2 +/- 0.88 cm and 3.0 +/- 1.1 cm respectively. There was a negative correlation between the weight of the animal and the height of the cerebellum, the length of cerebrum and length of the cerebellum and between the weight of the head and height of the cerebellum. A positive correlation was however observed between the length of brain and the weight of brain, and between the length of the cerebrum and weight of brain. The cerebral length was statistically longer (P < 0.01) in the males than the females. The data obtained from this study will provide added information in the field of comparative anatomy and porcine neuroanatomy research.
