In an experiment to determine the effects of variations in weight on the acetycholinesterase (AChE) activity and total protein concentration in the brain regions and hypophyses of pigs commercially reared in the tropics, a total of 80 pigs were sorted into 8 body weight categories with 10 pigs in each body weight category. The pigs were sacrificed and their brain regions and hypophyses assayed for AChE activity and for total protein concentration. The body weight categories were 21-30, 31-40, 41-50, 51-60, 61-70, 71-80, 81-90 and 91-100kg. Bothe sexes were equally represented in each category. Acetylcholinesterase activity was highest in the amygdala, hippocamus and mid-brain of pigs within the 41-70kg weight categories and lowest in the cerebral cortex of pigs within the 31-40kg weight category although the differences were not significant (P>0.05). Variations in mean Specific Acetylcholinesterase (SAChE) activity and in mean concentration of total proteins with pig body weight and brain regions/hypophyses were highly significant (P
