rabbits in the tropics. Due to the deleterious effects of papain (in pawpaw
parts) on some aspects of the physiology of livestock, an investigation was
made of the effect of pawpaw peel meal on the total protein and cholesterol levels of the brain regions of male rabbits using 16 bucks of mixed breeds. The animals were randomly allotted in groups of 4 to 4 dietary treatments containing 0% (control), 10%, 20% and 30% pawpaw peel meal. After 7 weeks of feeding, all the animals were sacrificed and the total protein and cholesterol concentrations in the brain regions evaluated. The results showed similarities (P>0.05) between the treatments in total protein concentrations in the cerebral cortex, medulla, hypothalamus, amygdala, mesencephalon and hippocampus. Total protein concentrations however differed significantly between diets (P
