Breakfast foods vary widely according to culture, location and resources but should contain major nutrient, a carbohydrate such as grains or cereals, fruit and/or vegetables, a protein food such as eggs, meat or fish, and a beverage such as tea, coffee, milk or fruit juice, Coffee, and milk. The objective of this study is to prepare breakfast foods from animal polypeptide, maize and crayfish were the sole energy and protein source respectively. Diet 1, nitrogen free diet (Basal), diet 2 (Crayfish: fermented maize 10g: 100g), diet 3 (Crayfish: fermented maize15g: 100g), diet 4 control (milk based). The formulated breakfast diets were fed to 50 albino rats. A commercial product, milk based commercial breakfast (MBCB) was used as standard diet. The results revealed that the growth response, (non protein dietary) declined from 24.62- 23.79g, (protein dietary) increased from 23.36-45.74, 24.50-40.77, and 24.43-37.81g, for diets 1 2, 3, and 4 respectively. Animal polypeptide (Diet 2) at combination of 10g: 100g performed better than 15g: 100g combination. It may be suggested that (Diet 2) at combination of 10g:100g could have complete amino acid profile that could sustained body for daily activities and meet daily requirements when compared to other formulated dietary. Animal polypeptide (crayfish) supplement to energy obtained from maize at 10g: 100g promoted the best growth performance. http://pubs.sciepub.com/ajfn/4/5/3/ajfn-4-5-3.pdf breakfast optimum nutrient polypeptide
