The response to substitution of soybean with faba bean protein concentrate on hepatic transcriptome of Atlantic salmon (Salmo salar)


ABSTRACT: The production of carnivorous fish such as Atlantic salmon (Salmo salar) is dependent on the availability of high quality protein required as a sustainable substitute for the formulation of the feeds. Plants have arguably the greatest potential, however a major limitation is associated with the presence of anti-nutritional factors. Investigating novel raw materials involves understanding the physiological consequences of the substitution. The primary aim of the present study was to assess the metabolic response of salmon to increasing inclusion of air-classified faba bean protein concentrate (BPC) in feeds as a replacement for soy (SPC). Specifically, we focused on the hepatic transcriptome response to dietary BPC inclusion over a range including commercially relevant levels (e.g. 11-22%) to levels giving impaired performance (45 %). The present investigation provided a profile of the salmon hepatic response to BPC indicating that fish tolerated moderate substitution of dietary SPC with BPC with no evident negative effects on the hepatic physiology of the fish. The analysis of extreme levels of substitution provided insights into physiological mechanisms that are significantly altered providing the basis for further investigation and improvement.
