    • Safe limits of selenomethionine and selenite supplementation to plant-based Atlantic salmon feeds 

      Berntssen, Marc; Betancor, Mónica B.; Caballero, María José; Hillestad, Marie; Rasinger, Josef Daniel; Hamre, Kristin; Sele, Veronika; Amlund, Heidi; Ørnsrud, Robin (Journal article; Peer reviewed, 2018)
      The use of plant-based feeds warrants the supplementation with selenium (Se) to cover the requirement for Atlantic salmon. Depending on its chemical form, Se is a trace element with a narrow range between requirement and ...

    • Selenium and selenium species in feeds and muscle tissue of Atlantic salmon 

      Sele, Veronika; Ørnsrud, Robin; Sloth, Jens Jørgen; Berntssen, Marc; Amlund, Heidi (Journal article; Peer reviewed, 2018)
      Selenium (Se) is an essential element for animals, including fish. Due to changes in feed composition for Atlantic salmon (Salmo salar), it may be necessary to supplement feeds with Se. In the present work, the transfer ...

    • Subchronic dietary exposure to ethoxyquin dimer induces microvesicular steatosis in male BALB/c mice 

      Bernhard, Annette; Rasinger, Josef Daniel; Wisløff, Helene; Kolbjørnsen, Øyvor; Myrmel, Lene Secher; Berntssen, Marc; Lundebye, Anne-Katrine; Ørnsrud, Robin; Madsen, Lise (Journal article; Peer reviewed, 2018)
      The use of the synthetic antioxidant ethoxyquin (6-ethoxy-2,2,4-trimethyl-1,2-dihydroquinoline; EQ) in animal feed results in the presence of EQ residues and metabolites, including the EQ dimer (1,8′-bi(6-ethoxy-2,2,4-tr ...

    • Tolerance and dose-response assessment of subchronic dietary ethoxyquin exposure in Atlantic salmon (Salmo salar L.) 

      Bernhard, Annette; Rasinger, Josef Daniel; Betancor, Mónica B.; Caballero, María José; Berntssen, Marc; Lundebye, Anne-Katrine; Ørnsrud, Robin (Journal article; Peer reviewed, 2019)
      Ethoxyquin (EQ; 6-Ethoxy-2,2,4-trimethyl-1,2-dihydroquinoline) has been used as an antioxidant in feed components for pets, livestock and aquaculture. However, possible risks of EQ used in aquafeed for fish health have not ...

    • Use of (Q)SAR genotoxicity predictions and fuzzy multicriteria decision-making for priority ranking of ethoxyquin transformation products 

      Rasinger, Josef; Frenzel, F.; Braeuning, A.; Bernhard, Annette; Ørnsrud, Robin; Merel, Sylvain Alain Yves; Berntssen, Marc HG (Peer reviewed; Journal article, 2022)
      Ethoxyquin (EQ; 6-ethoxy-2,2,4-trimethyl-1,2-dihydroquinoline) has been used as an antioxidant in feed for pets and food-producing animals, including farmed fish such as Atlantic salmon. In Europe, the authorization for ...

    • Utfordringer som hindrer økt utnyttelse av marine restråstoff og marine arter 

      Vang, Birthe; Lian, Kjersti; Berntssen, Marc HG; Ørnsrud, Robin; Sele, Veronika; Solstad, Runar Gjerp; Pleym, Ingelinn Eskildsen; Svorken, Marianne; Steinsholm, Silje; Aas, Turid Synnøve; Kokkali, Marialena; Carvajal, Ana Karina; Dragøy, Ragnhild (Nofima rapportserie, Research report, 2021)
      Regjeringen har i flere meldinger uttalt at det skal legges til rette for økt verdiskaping i sjømatnæringen. Et bidrag inn mot dette er utvikling innen sirkulær bioøkonomi og innføring av en mer bærekraftig produksjon og ...

    • Utnyttelse av P fra sildeavskjær som alternativ P kilde i fôr til laksesmolt (Salmo salar L.) 

      Albrektsen, Sissel; Lock, Erik-Jan; Bæverfjord, Grete; Pedersen, Mona Elisabeth; Krasnov, Aleksei; Takle, Harald Rune; Veiseth-Kent, Eva; Ørnsrud, Robin; Waagbø, Rune; Ytteborg, Elisabeth (Nofima rapportserie, Research report, 2014)
      Målet med dette prosjektet var å øke verdiskapningen av marint restråstoff ved å utvikle bioteknologiske løsninger som kan frigjøre P fra fiskebein og gjøre P mer tilgjengelig for laks, samt å utvikle nye marine P ingredienser ...

    • Zinc uptake in fish intestinal epithelial model RTgutGC: Impact of media ion composition and methionine chelation 

      Prabhu, Antony; Stewart, Theodora; Carreiro-Silva, Marina; Amlund, Heidi; Ørnsrud, Robin; Lock, Erik-Jan; Waagbø, Rune; Hogstrand, Christer (Journal article; Peer reviewed, 2018)
      Apical uptake of zinc as ionic Zn(II) or as Zn-methionine (Zn-Met) was studied in RTgutGC cell line in vitro under media compositions mirroring the gut luminal ionic concentration of freshwater (FW) and seawater (SW) ...
