Objective: To investigate the ameliorating potentials of cocoyam (Colocasia esculenta (C.
esculenta) L.) and unripe plantain (Musa paradisiacae (M. paradisiacae) L.) incorporated feeds
on renal and liver growth of STZ induced rats. Method: The blood glucose level of all the rats
was measured with a glucometer, the protein and glucose levels in the urine samples of the rats
were determined using urine assay strips while the specific gravity of the urine samples of all
the rats was determined with a urinometer. The assay of the proximate, phytochemical, mineral
composition as well as screening for antioxidant activity of the test feeds was carried out using
standard techniques. Results: The administration of the test feeds for 21 days to the diabetic
rats of groups 4 and 5, resulted in 58.75% and 38.13% decreases in their hyperglycemia with a
corresponding amelioration of their elevated urinary protein, glucose, specific gravity as well
as renal and kidney growths. Administration of the cocoyam incorporated feeds to the diabetic
rats of group 4, resulted in 2.71% increase in body weight with a corresponding 19.52% increase
in growth rate unlike the diabetic rats of group 5, administered unripe plantain feed that had
5.12% decrease in weight with a corresponding 29.52% decrease in growth rate but higher than
the diabetic control rats that recorded 28.69% and 29.46% decreases in body weights with a
corresponding 248.9% and 250.14% decreases in growth rates. Analysis revealed that the test
feeds contained low quantities of moisture but significant quantities of crude fibre, proteins,
lipids, carbohydrates, ash, alkaloids, flavonoids, saponins, tannins, calcium, magnesium,
potassium, iron, zinc, phosphorous as well as considerable amount of energy. In addition, the
cocoyam incorporated feeds contained higher quantities of flavonoids, saponin, tannin, Ca, Mg,
Fe, Zn, K, P, crude fibre as well as antioxidant activity but lower quantities of alkaloids than the
unripe plantain feed. Conclusion: The use of cocoyam and unripe plantain flours in the dietary
management of diabetes mellitus could be a breakthrough in the search for plants that could
