Preliminary morphometric investigation of the brain Of red sokoto (maradi) goat.

Abstract

Morphometric studies were undertaken of the brain of Red Sokoto goat. A total of 13 frozen/unfixed specimens were used. The mean brain weight was 85.85±10.85g, mean brain length (from cerebrum, rostral to the coronal sulcus to the medulla oblongata at the level of the occipital condyles) was 10.19±0.52cm and the mean brain depth/ height was 4.67±0.34cm (measured from the level of the hypothalamus to the top of the cerebrum). The mean cerebellum depth, length and cerebrum length was 3.72±0.44cm, 2.83±0.39cm and 6.42±0.28cm respectively. The average ratio of brain to body weight was 0.006 or 1:165. There were no significant differences in brain linear dimensions, brain weight and brain to body weight ratio between male and female. There was, however, a significant difference P<0.05) between the brain weight and length, cerebellum depth, length and cerebrum length of animals between 15kg and those above this weight mark.
