The mitigating role of lysophospholipids in hepatic lipid metabolism and intestinal immunity in juvenile black seabream (Acanthopagrus schlegelii) fed a high-fat diet

An 8-week feeding experiment investigated the effects of lysophospholipids (LP) on growth performance, hepatic lipid metabolism, intestinal immunity and antioxidation in juvenile black seabream (Acanthopagrus schlegelii) (initial weight 4.60 ± 0.01 g) on a high-fat diet. Five experimental diets were established: normal fat diet (13 %, CON), high-fat diet (18 %, HFD) and HFD with different levels of LP (0.05 %, 0.1 %, and 0.2 %). The results indicated that dietary LP had no impact on the specific growth rate and survival rate of juvenile black seabream (P > 0.05), while 0.2 %LP supplementation reduced the intraperitoneal fat ratio (IPF) (P
