| The influence of dietary phospholipid (PL) composition on early development was tested in a 25 day feeding trial with first-feeding common carp (<i>Cyprinus carpio</i>) larvae. A phosphatidylcholine (PC) fraction (PL: 94%, PC: 83%, PI: 1%) and a phosphatidylinositol (PI) fraction (PL: 100%, PC: 3%, PI: 64%) were prepared from soybean lecithin and added (2% on diet dry weight) to a casein-dextrin basal diet. Another diet was supplemented with 2% hen egg yolk PL (PL: 97%, PC: 68%, PI: 0%). A PL-deficient diet contained only peanut oil as lipid source and another one was supplemented with inositol. Final larval morphology was examined by an automatic image analysis system. The three PL fractions markedly improved growth in comparison with... |
