The present study aimed to evaluate the use of organic and inorganic minerals in Cobb500 broiler breeder diet and its effects on the performance. The birds were housed in an experimental house at Poultry Laboratory of the Federal University of Santa Maria with 20 floor pens of 4.61m2 each. The experiment was conducted between 51st and 65th weeks of age of birds. The design was completely randomized with four treatments and five pen replicates with 22 hens and 2 roosters each. The treatments evaluated were: PI=100% mineral inorganic premix; PO= 100% mineral organic premix: PI+PO= 70% mineral inorganic premix + 30% mineral organic premix and PI+Zn= 100% mineral inorganic premix, except zinc mineral, that was 70% inorganic form and 30% organic form. The following parameters of performance and egg quality were evaluated: laying rate, body weight, egg, albumen and yolk weight, yolk color and specific gravity of eggs. These parameters were performed one day per week throughout the experimental period to evaluated egg quality. Under the conditions and time that the experiment was conducted, the use of organic minerals had no significant effect on the performance and egg quality parameters evaluated in the broiler breeders.
