Resumo
This study aimed to evaluate the effect of including soy lecithin emulsifier (SL) in broiler diets on the reduction of
metabolizable energy levels and to correlate it with nutrient metabolizability coefficients and the determination of apparent
metabolizable energy (AME). Two metabolic trials were conducted in a completely randomized design, with a 3x2 factorial
arrangement (feed with three levels of metabolizable energy, with or without the inclusion of an emulsifier in the diet),
totaling six treatments. In the starter phase, chicks received feed with 2,950; 3,050; and 3,150 kcal/kg of metabolizable
energy, with six replications of 10 birds each, totaling 360 birds. In the grower phase, 210 birds were used, with seven
replications of five chicks, and the energy levels tested were 3,100; 3,150; and 3,200 kcal/kg of feed. In the starter phase,
an interaction effect was observed, showing an increase in the nitrogen metabolizability coefficient (NMC) when adding the
emulsifier to diets with reduced energy, as well as an effect of the emulsifier in increasing the AME corrected by the balance
of nitrogen (AMEn). In the grower phase, an interaction effect was observed, showing an increase in AME and AMEn when
adding the emulsifier to diets with lower energy levels. To sum up, emulsifier inclusion in broiler diets can reduce
metabolizable energy while improving AMEn in both initial and grower phases, along with AME in growing broilers.
