Comparison of EPA and DHA utilization in Atlantic salmon (Salmo salar) and rainbow trout (Oncorhynchus mykiss) fed two diets with different content of fish oil and rapeseed oil
Berge, Gerd Marit; Krogdahl, Åshild; Hillestad, Marie; Holm, Halvor; Holm, Jørgen; Ruyter, Bente (Peer reviewed; Journal article, 2021)Atlantic salmon and rainbow trout with initial weights of 460–468 g were fed two diets either high in fish oil (FO) or rapeseed oil (RO) content. The abilities of the fish to metabolize and deposit lipid and n-3 fatty acids ... -
Effects of dietary moisture content of extruded diets on physical feed quality and nutritional response in Atlantic salmon (Salmo salar)
Oehme, Maike Marlene; Aas, Turid Synnøve; Olsen, Hanne; Sørensen, Mette; Hillestad, Marie; Li, Yafei; Åsgård, Torbjørn Einar (Peer reviewed; Journal article, 2014)Feeds in modern aquaculture must be of high physical quality to withstand mechanical impacts. However, physical quality of feed has been shown to affect nutritional responses. In this study, different physical feed qualities ... -
Effects of dietary moisture content of extruded diets on physical feed quality and nutritional response in Atlantic salmon (Salmo salar) - A CREATE project
Oehme, Maike Marlene; Aas, Turid Synnøve; Olsen, Hanne Jorun; Sørensen, Mette; Hillestad, Marie; Li, Yafei; Åsgård, Torbjørn Einar (Nofima rapportserie, Research report, 2012)Feed pellets in modern aquaculture must be of high physical quality to withstand impacts during transport, storage and feeding. However, physical quality of feed has been shown to affect feed intake, nutrient digestibility ... -
Feed intake and nutrient digestibility and retention in Atlantic salmon fed diets with different physical pellet quality. A CREATE project
Aas, Turid Synnøve; Sixten, Hanne Jorun; Hillestad, Marie; Ytrestøyl, Trine; Sveier, Harald; Åsgård, Torbjørn Einar (Research report, 2015)Three extruded salmon diets (9 mm) were produced with the same formulation but different physical pellet qualities. Pellet quality was measured in terms of bulk density, durability (Ligno and DORIS test), fat leakage, ... -
Feed intake, nutrient digestibility and nutrient retention in Atlantic salmon (Salmo salar L.) fed diets with different physical pellet quality
Aas, Turid Synnøve; Sixten, Hanne Jorun; Hillestad, Marie; Ytrestøyl, Trine; Sveier, Harald; Åsgård, Torbjørn Einar (Peer reviewed; Journal article, 2020) -
Gastrointestinal passage rate in Atlantic salmon (Salmo salar) fed dry or soaked feed. A CREATE project
Aas, Turid Synnøve; Ytrestøyl, Trine; Hatlen, Bjarne; Sixten, Hanne Jorun; Hillestad, Marie; Åsgård, Torbjørn Einar (Research report, 2013)Atlantic salmon was fed a commercial-like diet either as is (92% dry matter) or soaked for 2 h in sea water prior to feeding (70% dry matter). The salmon showed large individual variation in gastrointestinal passage rate ... -
Gut evacuation rate in Atlantic salmon (Salmo salar) fed diets with different physical properties. A CREATE project
Aas, Turid Synnøve; Ytrestøyl, Trine; Hatlen, Bjarne; Sixten, Hanne Jorun; Hillestad, Marie; Sveier, Harald; Selset, Roger; Åsgård, Torbjørn Einar (Research report, 2014)To measure the effect of physical feed quality on gut evacuation, Atlantic salmon with mean weight 1047 g (measured after finishing the sampling) was fed two extruded feeds with different physical quality to satiation. ... -
Interaction of soyasaponins with plant ingredients in diets for Atlantic salmon, Salmo salar L
Chikwati, Elvis M; Venold, Fredrik Føllesdal; Penn, Michael; Rohloff, Jens; Refstie, Ståle; Guttvik, Arne; Hillestad, Marie; Krogdahl, Åshild (Peer reviewed; Journal article, 2012)The effects of combining soyasaponins with plant ingredients on intestinal function and fish health were investigated in an 80 d study with Atlantic salmon (270 g) distributed thirty each into twenty-four tanks with seawater. ... -
