نبذة مختصرة : Fish waste, when used as raw material, is considered a valuable byproduct due to its nutrient content, and through transformation processes, it can help prevent environmental pollution. The waste generated from fishing activities is not adequately treated in terms of its final disposal, which contributes to environmental contamination. Additionally, these waste materials are not used rationally due to a lack of knowledge regarding the applicable technological processes for utilizing the byproducts generated on a daily basis. This study aims to characterize and utilize these agro-industrial waste materials in the production of biological silage. The objective of this research was to obtain biological silage using fish waste in Gamarra (Cesar). An experimental factorial design of 2 x 3 was employed, with the first factor being the carbon source (molasses) at two levels of 12% and 18%, and the second factor being the fermenting agent, which utilized yogurt at three levels of 6%, 11%, and 15%. These factors were evaluated at a confidence level of 95% (P<0.05), resulting in six treatments with four replications each (24 experimental units). The mixtures obtained were placed in plastic reactors and kept at room temperature for 15 days, with pH and acidity levels monitored throughout the experiment. After this period, the silage was subjected to hot air drying. The final product exhibited protein levels ranging from 32% to 43% and fat content ranging from 19% to 33%. Microbiological analysis confirmed the product's safety as animal feed, making it suitable for consumption. ; Los desechos del pescado como materia prima, aprovechando estos se consideran como un subproducto valioso por ser fuente de nutrientes que con procesos de transformación pueden llegar a evitar problemas de contaminación ambiental. Los residuos provenientes de la pesca no tienen un tratamiento adecuado referente su disposición final, siendo un factor contaminante del ambiente, además no son utilizados de manera racional, debido al desconocimiento ...
