Quality Protein Maize (QPM) cultivar BR 473 was employed, together with soybean flour, brown sugar, banana meal and oat meal, for the preparation of a nutritional supplement.. 21-day old male Fisher rats were fed diets containing the supplement as a protein source, both with and without soybean flour; casein diets with 10 or 7% protein served as respective controls. Protein Efficiency Ratio (PER), Net Protein Utilization (NPU), Net Protein Retention (NPR) and Digestibility were determined. Blood biochemical parameters (glucose, cholesterol, urea, hemoglobin, albumin and total protein) were also measured in the animals and showed that all were in good health condition at the end of the experiment. The obtained results for PER, NPU and NPR indicated that the supplement prepared with QPM maize cultivar BR 473 was a good protein source, especially when soybean flour was added.
