title: Metabolomic analysis of plasma and liver from surplus arginine fed Atlantic salmon.
abstract: The aim of this study was to determine the metabolic effect of surplus arginine (36.1 g/kg dry matter) compared to a control diet with required arginine (21.1 g/kg dry matter) in adult Atlantic salmon (Salmo salar L.). Although the feeding trial had no significant effect on growth, there were significant differences in the metabolite profile in both plasma and liver in experimental group as compared to the control group. There was increased concentrations of biliverdin, PGF-2 alpha, oxidized glutathione, selenocysteine, two monoacylglycerols and a tripeptide in the liver as well as decreased concentrations of valine and a vitamin D3 metabolite in plasma of arginine supplemented fish. These results indicate that while surplus arginine does not affect growth or body weight, it induces metabolic changes in Atlantic salmon.
