The present research aims to evaluate the inclusion of an emulsifying additive based on mono- and diglycerides of fatty acids in diets with different lipid sources, studying its effects on duodenum histology, biometry of the digestive and reproductive tract, and blood biochemical profile of Japanese quails. The study was carried out in the experimental aviary of the Federal University of Grande Dourados, Mato Grosso do Sul, Brazil. The experimental design was completely randomized, with diets in a 3x2 factorial design with three different lipid sources (soybean oil, poultry fat, and beef tallow), either supplemented or not with an emulsifier. The birds that received a diet composed of poultry fat and an emulsifying additive had a larger gizzard. Animals that received a diet containing an emulsifier, regardless of the lipid source, had greater heart weight. The duodenum of animals that received bovine tallow in their diet showed a greater height and villus:crypt ratio. Biochemical parameters were not affected by either the lipid source or the inclusion of emulsifier in quail diets. The biochemical blood profile of birds in treatments did not show significant changes among all diets used. The use of soybean oil, bovine tallow, and poultry fat with or without the inclusion of an emulsifier does not show changes in the health and development of the quails' organs, which also indicates that the health of Japanese quails in the laying phase is kept in good standards.(AU)
