Fishing exploitation, for the purpose of marketing and consumption in the Cíenaga de Zapatosa, Cesar, Colombia, generates a large amount of waste represented in viscera and other by-products. The possibility of using these viscera for the production of flour for animal feed was studied. For the by-products from the six most important fish species in the Cíenaga de Zapatosa, their proximal composition was determined, and the respective flour, using a mixture in equal proportions elaborated evaluated. The final product was evaluated through bromatological, microbiological and stability parameters. The flour was elaborated through the procedures of cooking, pressing, centrifugation for the elimination of fat and humidity, draying, grinding, packaging and storage. The results showed a stable nutritional value during the measurement time, which makes it a favorable protein option for the production of animal feed, due to its digestibility of 80%, its protein content of 54%, its contribution in essential fatty acids eicosapentaenoic (EPA), docosapentaenoic (DPA), docosahexaenoic (DHA) and its contribution in essential amino acids. This flour was evaluated in the preparation of concentrated feeds for in vivo feeding of broilers, compared with commercial feed. The result showed a better productive performance represented in better daily weight gain and better feed conversion index. The results allow to conclude that the meal of fish viscera of the six most commercially important species obtained in the Cíenaga de Zapatosa, are an important alternative for feeding broilers.
