| Abstract | Triplicate groups of Atlantic salmon (Salmo salar) fingerlings, about 4.7+or-0.2 g, were fed to appetite on diets containing 1.24, 1.76, 1.90, 2.19, 2.45, 2.68 and 2.94% lysine and gross energy 24.1 MJ/kg of diet (DM basis, DMB) for 70 days. The salmon were reared in water salinity 10 ppt at 15 degrees +or-0.9 degrees C with 12-h photoperiod. The dietary requirement for lysine, estimated by broken-line regression of growth against dietary lysine (DBM), was 1.99+or-0.11%, or 3.98% of the protein when protein was 50.0% of the diet. A dietary lysine requirement of 1.84+or-0.16 to (DMB) was estimated from broken-line regression of expired 14CO2 (following an intraperitoneal injection of L[U-14C]lysine) against dietary lysine concentration. Except for loss of appetite, resulting in low feed intake and decreased growth, no nutritional deficiency signs were seen in fish fed on a lysine-deficient diet for 140 days.. |
