Low fishmeal diets for Atlantic Salmon, Salmo salar L.,using soy protein concentrate treated with graded levels of phytase
The experiment aimed at determining the efficient use of phytase (Phy) inAtlantic salmon diets that had low (4.5%) fishmeal and contained 60% soy protein concentrate(SPC). Phytase was either included at 250, 500, 1,000 or 4,000 U Phy kg-1 diet orthe SPC was pre-treated prior to making diets using 25...
