The Digestibility and Accumulation of Dietary Phytosterols in Atlantic Salmon (Salmo salar L) Smolt Fed Diets with Replacement Plant Oils
Phytosterols occur in high concentration in canola (Brassica napus L.) and other vegetable oils such as from the borage plant Echium (Echium plantagineum L.). We investigated if Atlantic salmon (Salmo salar) digest and accumulate dietary phytosterols in significant amounts in muscle and liver. Phyto...
