The aim of the present investigation was to determine the effects of the use of acidulated soybean oil in replacement (weight to weight) of crude soybean oil in diets for rainbow trout fry (Oncorhynchus mykiss). The productive parameters that were evaluated were feed intake, weight gain, size increase, feed conversion, survival, protein efficiency ratio and feed cost. Two hundred and sixteen rainbow trout fingerlings with an average weight of 1.47 ± 0.3 g and a size of 4.1 - 5.2 cm were used, which were distributed in 9 aquariums. The fish were assigned to 3 treatments, each with 3 repetitions. Treatments included two types of oil: acidulated soybean oil (AAS) and crude soybean oil (ACS) in the ratio 0: 5.0 (T1), 2.5: 2.5 (T2) and 5.0: 0 (T3). Experimental diets were elaborated in the Food Plant of the Program of Social Projection of the National Agrarian University La Molina, according to the nutritional requirements of the fish in the beginning stage in compliance to NRC (2011). The weights and sizes of the fish were calculated at the beginning and at the end of the investigation. The diets were subjected to a proximal analysis. The results showed that there is no significant difference between treatments for any parameter (p> 0.05). A reduction in costs up to 5.12% was obtained with respect to the use of ACS. It is concluded that it is feasible to use acidulated soybean oil at the levels evaluated in replacement (weight to weight) of the crude soybean oil without affecting the productive performance of the trout at a lower cost.
