Lysolecithin is added to broiler diets to enhance fat digestibility. Their interaction with the origin of the dietary fat source needs further investigation. The effect of a soy lysolecithin on digestibility was examined using a titanium dioxide tracer method. A corn-based broiler diet was formulated with either 5.3% soy oil or 5.8% pig lard. Ross 308 male broilers (3/pen and 6 replicates/diets) were assigned to 4 dietary treatments: a basal diet with soy oil (T1), a basal diet with pig lard (T2), and both T1 and T2 supplemented with 250 ppm lysolecithin (T3, T4, respectively). Dry matter (DM) digestibility, nitrogen retention and AMEn were lower (P<0.05) for T2 compared to T1. Addition of lysolecithin improved (P<0.05) DM digestibility of the pig lard diet by 5.1%, nitrogen retention by 2.8 g/kg and AMEn by 760 kJ/kg. For the soy oil diet, lysolecithin also enhanced nitrogen retention (P<0.05) by 0.81 g/kg, whereas a tendency for improved DM digestibility and AMEn were observed. This study demonstrates that soy lysolecithin can improve nutrient digestibility and AMEn of broiler feed but that these improvements depend on the fat source incorporated.
