ABSTRACT: The purpose of this study is to enhance the senescent plantain by making dockounou with a nutritional value for feeding Wistar rat. Batches of rats were fed with dockounou boiled and formulated with millet, soybean, sorghum, cassava, maize and rice flours for 15 days. The parameters such as weight gain, dry matter intake, feed efficiency and the digestibility of various dishes of dockounou were evaluated. It appears that apart from the control diet, only the dockounou of soybean made a weight gain to 2.05 g/d and 2.25 g/d obtained respectively with the formulation 80:20 and 75:25. The high dietary intakes to 7.18 g/d and 7.51 g/d were respectively obtained at 80:20 and 75:25 formulations for the same diet. Furthermore, there is no significant difference in the food efficiency and the digestibility dockounou of soybean at both formulated and the control diet. Regarding nutritional performance of dockounou of soybean formulated to 80:20; this food could be used in the diet of Wistar rat. KEYWORDS: senescent plantain, nutrient intake, dockounou, growth performance, digestibility. 1 INTRODUCTION Plantains (Musa ssp) constitute a major source of carbohydrates for millions of people in Africa, the Caribbean, Latin America, Asia and Pacific [1], [2]. For that, they play an important role in the economy and food security of many wet tropical regions in the world [2]. It constitutes the fourth most important global food commodity after rice, wheat and maize [3] [4]. In fact, plantain is an agriculture product with carbohydrates accounting for 22% of fruit weight and rich in vitamins A, B6, C, minerals and dietary fibre [5][6]. According to [7] plantain (1,577 043 tons/year) is the third food crops in Ivory Coast after yams (3,000 000 tons/year) and cassava (1,700 000 tons/year). In spite his importance, plantain is a highly perishable fruit, which requires processing into a more stable and convenient form. Indeed, any factor can accelerate banana ripening which are the deplorable transport conditions, the absence of adequate structures of conservation and storage on the markets. This factor can also accelerate the degradation about 35 to 60% of plantains [8] [9], [10], [11]. To face the problem of short life of plantain, processing or preservation treatments are often used whose the aim is to decrease (plantain degradation) (the post-harvest losses) [12]. However studies carried by [13] showed deficiencies in the content of essential nutrients such as proteins and lipids making dockounou a food of low nutritional value. Another work according [14], at this food were improved the production parameters, the quantity of plantain senescent used, the duration of fermentation and cooking, etc. These parameters had improved organoleptic characteristics without that there is a contribution in terms of nutritional value. One solution to this problem is the preparation of dockounou to different proportions with other types of flour derived from cereal such as millet, sorghum, leguminous such as soybean, cassava root which are usually met on our markets. The aim of this study is to valorized senescent plantain by producing nutritional feed capable to contribute at the growth of the young rats Wistar.
