In recent years, special attention has been given to dietary supplementation for laying hens with sources of chelated or organic minerals, so called because they consist of metallic ions bound to organic substances. This connection can make them more stable and less subject to interactions, therefore, more available to the organism when compared to inorganic forms. The objective was to determine the effect of organic mineral supplementation on the performance and quality of eggs of laying hens at the end of production. Two flocks of birds of the same age were selected. In the first batch, 780 birds of the Hisex White lineage were used, fed diets containing the inclusion of the product containing organic minerals. In the second batch, a total of 780 Hisex White birds received the control diet (without addition of organic minerals). The birds were distributed in 60 cages (13 birds/cage). The cages were identified and homogeneously distributed in a specific region of the shed. Each of the 60 cages was isolated to measure the percentage of posture and daily mortality. At the end of each cycle, egg quality analyzes were carried out, totaling 4 cycles of 28 days, where the following variables were measured: breaking strength, translucency score, shell thickness, specific gravity, egg weight, shell weight and characteristics internal egg quality. Thus, at the end of the experiment, it can be seen that the use of organic minerals for laying hens in the final stage of production positively influenced most of the egg quality variables in all evaluated cycles.
