The productive response in second fry of trout “steelhead” (Oncorhynchus mykiss), prevenient from premium eggs with two extruded foods was determinated. The productive parameters that were evaluated were, unit weight gain, biomass gain, feed consumption, feed conversion, growth rate, survival and feed cost per kilogram of weight gain. An estimated 32,760 trout “steelhead” (Oncorhynchus mykiss) fingerlings with an average weight of 3.67 ± 0.19 were used, which were distributed in 6 pools. The fish were assigned to 2 treatments, each with 3 repetitions. The treatments included two types of extruded balanced foods: La Molina and Nicovita. The experimental diets of the La Molina food were prepared at the Food Plant of the Research and Social Projection Program, Faculty of Zootechnics, La Molina National Agrarian University, according to the nutritio nal requirements of the trout in the initial stage, applying the results obtained in research and commercial breeding. Fish weights were calculated at the beginning and at the end of the research. The diets were subjected to a proximal analysis. The resultsshowed that there were no significant differences between the treatments for unit weight gain, biomass gain, feed consumption, growth rate and feed conversion (P> 0.05). Regarding the survival rate, the best results were obtained with the extruded balanced feed La Molina. In addition, with this feed a decrease in feeding costs of 3.85 per cent was obtained. It is concluded that it is feasible to use the extruded La Molina balanced feed without affecting the productive performance of t trout at a lower cost.
