Notes:
The effects of L-carnitine (0 vs. 450mg added L-carnitine/kg diet) with different dietary levels of L-lysine (4.7 vs. 5.3 g Lys/16gN) and sulphur amino acids (3.2 vs. 3.5g Met + Cys/16gN) on growth and feed efficiency were studied over 84 days in a total of 480 rainbow trout fingerlings (Oncorhynchus mykiss) with a mean body weight of 20g per fish. In fish receiving diets marginally deficient in lysine and methionine, L-carnitine improved specific growth rate (+4%) and feed efficiency (+ 8%) significantly (P 〈 0.05). The effect of carnitine on body weight, weight gain and feed consumption was not significant. It is suggested that the lysine-sparing effect of carnitine can be traced back to metabolic effects of lysine on carnitine transport across membranes.
