The objective of this study was to determine the effect of different levels of organic minerals in Lohmann Brown laying hens on egg quality and zoo technical parameters, during a period between 50 to 62 weeks of age of the birds, 400 hens were used. The treatments applied were T0: inorganic minerals 100% (traditional food), T1: organic minerals (B-TRAXIM 2C) 100%, T2: organic minerals (B-TRAXIM 2C) 50% and T3: organic minerals (B-TRAXIM 2C) 25%. The zoo technical parameters recorded weekly were: mortality (%), feed conversion, bird weight (kg), eggs produced / treatments, broken eggs and feed consumption (g / day). Regarding the quality of the egg, the following were measured: yolk color, egg weight (g), resistance to rupture (Kgf), albumin height (mm), Haugh units, shell thickness (mm) and quality index (AAA; AA; A; B; C). For the variables of egg production, egg mass and broken eggs, significant differences were found between treatments (p <0.01), highlighting the diets with 100 and 50% organic minerals. For the variables of albumin height and Haugh units, the treatment with 100% organic minerals stood out, with respect to the variables of feed consumption, feed conversion, egg weight, yolk color, egg resistance, shell thickness and quality index, there were no significant differences between treatments (p> 0.01). When speaking of economic analysis in the last month, the benefit / cost ratio presented amounts between 2.60 and 2.59, respectively, the organic mineral treatments at 100 and 50%.
