Bioavailability of selenium from raw or cured selenomethionine-enriched fillets of Atlantic salmon ( Salmo salar ) assessed in selenium-deficient rats
The bioavailability of Se from raw and cured selenomethionine-enriched (Se-enriched) salmon fillets was assessed in Se-deficient male albino rats (Mol: Wist). A low-Se Torula yeast feed was supplemented with 0, 50, 100, 150 or 200 μg Se/kg as sodium selenite or as Se from raw or cured Se-enriched sa...

The bioavailability of Se from raw and cured selenomethionine-enriched (Se-enriched) salmon fillets was assessed in Se-deficient male albino rats (Mol: Wist).

Bioavailability of Se was assessed by metabolic balance, Se accumulation in femur, muscle, liver and plasma, and induction of Se-dependent glutathione peroxidase ( EC 1·11·1.9; GSHpx) in plasma as response parameters.
