DHA, docosahexaenoic acid; DE, digestible energy; CP, crude protein; EE, ether extract; CF, crude fibre; NE, net energy; ST, starch.

The digestible energies of the diets were calculated according to Noblet and Perez [18] using the following equation: DE = 4,151–(122×%ash)+(23.2×%CP)+(38.2×%EE)–(64.2×%CF). The net energies of the diets were calculated according to Noblet et al [19] using the following equation: NE = 2,796+4.15×EE+0.81×ST–7.07×Ash–5.38×CF.
