El valor nutricional durante la preparacion y conservacion de los ensilados sigue siendo de gran interes para el consumo humano y animal. El objetivo del estudio fue demostrar si el abalon rojo ( Haliotis rufescens ) consume el ensilado de alga parda ( Lessonia trabeculata ) en condiciones experimentales, en el Centro Acuicola de Morro Sama-Tacna FONDEPES, durante los anos 2017 y 2018. Se experimento con el grupo control (alga fresca) y dos tipos de ensilado, tratamientos: T1 (ensilado 0% en base seca) y T2 (ensilado 35% en base seca) durante 62 dias; determinandose en el alga fresca el contenido de proteinas, grasas, hidratos de carbono y energia, no se observo diferencias estadisticamente significativas (p<0.05) entre los tratamientos, excepto para el contenido de grasas. En los tratamientos, se observo la aceptacion del alimento durante 10 dias y se estimo el consumo del alimento, las tallas y pesos que fueron estadisticamente similares. Se concluyo que: los abalones consumen el ensilado y que los mayores porcentajes de la composicion bromatologica correspondio al T2, su consumo para la ganancia de peso y talla de Haliotis rufescens donde probablemente, estas variables aumenten cuando exista mayor porcentaje del ensilado con base en materia seca o mayores dias de consumo. El analisis microbiologico demostro que los ensilados son aptos para el consumo de la especie. ABSTRACT The nutritional value during the preparation and conservation of the silage is still of great interest for human and animal consumption. The objective of the study was to demonstrate if the Red abalone ( Haliotis rufescens ) consumes the silage of Brown seaweed ( Lessonia trabeculata ) under experimental conditions, on the Morro Sama-Tacna FONDEPES aquaculture Centre, during the years 2017 and 2018. We experimented with the control group (fresh seaweed) and two types of silage, treatments: T1 (silage 0% on dry basis) and T2 (silage 35% on dry basis) for 62 days; determining the content of proteins, fats, carbohydrates and energy in the fresh seaweed, no statistically significant difference (p < 0.05) were observed between the treatments, except for the fat content. Treatments, food acceptance was observed during 10 days and food consumption, sizes and weights were estimated with statistically similar. It was concluded that the abalone eat silage and the highest percentages of bromatological composition corresponded to T2, its consumption to gain weight and height of Haliotis rufescens where probably these variables increase when there is a higher percentage of silage based on dry matter or more days of consumption. Microbiological analysis showed that the silages are suitable for the consumption of the species.    Key words: silage algal, drying, food science, biomass.
