Moreover, soybean and rapeseed lysolecithin supplementation
improved (P < 0.05) DM digestibility
of the basal diet with pig lard by 5.1 and 5.7%,
respectively; nitrogen retention by 2.8 and 3.1 g/kg, respectively;
and AMEn by 182 and 199 kcal/kg, respectively. Despite the major difference in molecular composition,
there was, however, no impact of the lysolecithin
composition on in vitro and in vivo fat digestibility.
This study demonstrates that the improvements that
can be made with lysolecithin supplementation are
highly dependent on the fat incorporated in broiler
feeds.
