Abstract

Objectives: To evaluate the inclusion of acidulated soybean oil in diets for rainbow trout alevins (Oncorhynchus mykiss) on its performance under commercial conditions. Methodology: Forty thousand and five hundred rainbow trout alevins were used and raised in ponds. Three levels of acidulated soybean oil included in the diet of 0.0, 2.5 and 5.0 % were evaluated. The study was conducted for 60 days. The variables evaluated were weight gain, feed intake, feed conversion, length gain, survival, growth rate, protein efficiency retention and feed cost / kg of weight. The data obtained were analyzed using the analysis of variance of a completely randomized design. Results: The levels of acidulated oil used in the diets for trout alevins had a similar effect on the evaluated variables . (P > 0.05). Conclusions: The acidulated soybean oil can partially or totally replace the crude soybeanoil, up to 5.0 % in diets for rainbow trout alevinsKeywords: Soybean oil, alevins, trout, performance.

Highlights

The fishing resource is a very important food source in the world
The acidulated soybean oil has been used in broiler chickens (Bedoya, 2003; Pérez 2011) and fish such as tilapia and trout (Bazán, 2002; Aguilar et al, 2012; Herbas, 2017)
It has proven to be a good substitute for traditional input; in trout has not been evaluated in the stage of alevins in commercial conditions so the objective of the research is to evaluate the inclusion of acidulated soybean oil in rainbow trout alevins and its performance in commercial conditions

Summary

Introduction

The fishing resource is a very important food source in the world. The production of this resource has been developing and increasing in recent years (FAO, 2001). The acidulated soybean oil has been used in broiler chickens (Bedoya, 2003; Pérez 2011) and fish such as tilapia and trout (Bazán, 2002; Aguilar et al, 2012; Herbas, 2017). In these studies, it has proven to be a good substitute for traditional input; in trout has not been evaluated in the stage of alevins in commercial conditions so the objective of the research is to evaluate the inclusion of acidulated soybean oil in rainbow trout alevins and its performance in commercial conditions
