Resumo: This study was conducted to determine the composition and fatty acid profile of the Nile tilapia waste silage with the aim of investigating its nutritional potential. Four lots (5 kg each) of Nile tilapia waste was ground with 3% (w/w) formic acid, stored at 27°C room temperature for 90 days in polyethylene boxes with holes, through which gases went out and then the levels of moisture, protein, ash and total lipids were analyzed obtaining: 77.25, 16.31, 3.17 and 3.26% respectively. 22 types of fatty acids were identified in the range of 10 to 22 carbon atoms and the most abundant was oleic acid-18:1 (22:14%), followed by palmitic acid-16:0 (18.2%). Approximate ly 97% of fatty acids (FA) were identified in the silage, being 30.81% of saturated fatty acids (SFA), 38.42% of monounsaturated fatty acids (MUFA) and 27.32% of polyunsaturated fatty acids (PUFA) which characterize this product as an important source of essential fatty acids. All parameters indicate a good nutritional potential for acid silage of Nile tilapia, mainly in relation to fatty acids and protein content.

Cuatro lotes (5 kg cada uno) de despesca de la tilapia del Nilo se molieron con 3% (p/p) ácido fórmico, almacenados a 27ºC de temperatura ambiente durante 90 días en cubos de polietileno con un agujero, a través del cual los gases puedem salir y después se analizaron los niveles de humedad, proteína, cenizas y lipidos totales (77,25, 16,31, 3,17 y 3,26 %, respectivamente). En el ensilado se detectaron 22 tipos de ácidos grasos en el rango de 10 a 22 átomos de carbono, el más abundante fue ácido oleico-18:1 (22:14%), seguido por el ácido palmítico-16:0 (18,2%). Aproximadamente 97% de ácidos grasos (AG) fueron identificados en el ensilagem, 30,81% de ácidos grassos saturados (AGS), 38,42% de ácidos grasos monoinsaturados (AGMI) y 27,32% de ácidos grasos poliinsaturados (AGPI), ló que caracteriza este produto una fuente importante de ácidos grasos esenciales. Todos lós parâmetros indican un bueno potencial nutricional para el ensilado ácido despesca de la tilapia del Nilo, principalmente en relacione a lós ácidos grasos e contendo de proteína.Rev. Bras.
