Emulsifiers are used to improve fat absorption by increasing the total surface of the fat globules for enzymatic digestion. In a three-phase production trial, the Emulsifier B was added on top of two diets with a different unsaturated/saturated fatty acids (U/S) ratio (2.0 and 1.7) and FFA content but with a lower MEn content (-5.3%) compared to their respective reference diet. Each treatment consisted of six replicates with 30 male Ross 308 broilers. In the starter and grower period, the addition of the emulsifier compensated totally, both in low and high U/S ratio diets, the reduced MEn content and a comparable DWG and FCR were obtained. During the finisher period, however, diets with the combination of lower MEn and emulsifier showed a higher (P<0.05) FCR. Over the whole trial period, the FCR tended (P=0.093) to be somewhat higher in diets with lower MEn and emulsifier added. However, the adjusted FCR 2500 was comparable between diets and MEn content. The production performances show that the addition of the tested emulsifier was able to compensate for a 5.3% reduction of MEn. This effect was most clear in the starter and grower period, and for diets with a low U/S ratio.
