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.
本研究针对尼日利亚本地猪的颅面指数和神经形态测量学展开，研究对象为12头雄性猪和14头雌性猪，年龄在一岁半至两岁之间。所获得的舌长、舌重、锉长度、左耳郭长度、右耳郭长度、左耳郭宽度、右耳郭宽度、左外鼻孔高度、右外鼻孔高度及口裂长度的平均值分别为17±1.3厘米、90±16克、4.6±0.58厘米、13±1.3厘米、13±1.3厘米、8.7±1.5厘米、8.7±1.4厘米、0.98±0.12厘米、0.96±0.13厘米和19.51±2.89厘米，而平均脑重、平均脑长、大脑和小脑长度、脑高和小脑高分别为84±12克、6.9±1.5厘米、4.9±1.7厘米、2.2±1.0厘米、5.2±0.88厘米和3.0±1.1厘米。动物体重与小脑高度、大脑长度和小脑长度之间以及头部重量与小脑高度之间呈负相关。然而，脑长与脑重之间以及大脑长度与脑重之间呈正相关。雄性猪的大脑长度在统计学上比雌性猪更长（P<0.01）。本研究获得的数据将为比较解剖学和猪神经解剖学研究领域提供更多信息。
