Effects of dietary lysolecithin (LPC) on growth, apparent digestibility of nutrient and lipid metabolism in juvenile turbot Scophthalmus maximus L.
An 8-week trial was conducted to investigate graded levels of dietary LPC on growth, apparent digestibility (ADs) of nutrients and lipid metabolism in juvenile turbot Scophthalmus maximus L. Five experimental diets were formulated which contain 11% crude fat with graded amounts of LPC (0, 1000, 2500...

Each diet was fed to triplicate groups of turbot (initial body weight of 41 g) for 56d. Weight gain rate and specific growth rate of the fish fed LPC supplemented diets were significantly higher than the control groups, and the growth performance of the C-group was significantly lower than the others.

Both total cholesterol (T-CHO) and high density lipoprotein cholesterol (HDL-C) were up-regulated, meanwhile neither alanine aminotransferase (ALT) nor total protein (TP) were down-regulated by dietary LPC.
