Assessing mineral availability in fish feeds using complementary methods demonstrated with the example of zinc in atlantic salmon
Silva, Marta Sofia; Stewart, Thea; Amlund, Heidi; Sloth, Jens Jørgen; Araujo, Pedro; Lock, Erik Jan Robert; Hogstrand, Christer; Ørnsrud, Robin; Waagbø, Rune; Prabhu, P. Antony Jesu (Peer reviewed; Journal article, 2021)Assessing the availability of dietary micro-minerals is a major challenge in mineral nutrition of fish species. The present article aims to describe a systematic approach combining different methodologies to assess the ... -
Dietary selenium required to achieve body homeostasis and attenuate pro-inflammatory responses in Atlantic salmon post-smolt exceeds the present EU legal limit
Prabhu, P. Antony Jesu; Holen, Elisabeth; Espe, Marit; Silva, Marta Sofia; Holme, May-Helen; Hamre, Kristin; Lock, Erik-Jan; Waagbø, Rune (Peer reviewed; Journal article, 2020)Selenium (Se) supplementation either as inorganic or organic form was evaluated in Atlantic salmon post-smolt in vivo and in vitro. The basal diet was formulated to be low in fish meal and contain 0.24 mg Se kg−1; six other ... -
Effect of levels and sources of dietary manganese on growth and mineral composition of post-smolt Atlantic salmon fed low fish meal, plant-based ingredient diets
Phillip, Antony Jesu Prabhu; Silva, Marta Sofia; Kröeckel, Saskia; Holme, May-Helen; Ørnsrud, Robin; Amlund, Heidi; Lock, Erik-Jan; Waagbø, Rune (Journal article; Peer reviewed, 2019)The impact of dietary manganese (Mn) levels and sources on the growth and mineral composition of post-smolt Atlantic salmon (Salmo salar) fed practical diets was studied. Seven experimental diets were prepared with graded ... -
