Aimed to verify the effect of supplementation of different relations zinc organic and inorganic copper and compare the results with the control diet of Japanese quails in laying phase on performance and egg quality. Two simultaneous experiments were performed in the experimental area of the Federal University of Espírito Santo, the first a statistical regression, which varied the organic zinc levels (35, 50, 65 and 80 mg / kg diet) and kept the recommended copper levels 5mg / kg diet, four treatments and 320 Japanese quail distributed randomly in the second test in factorial arrangement 3x2 + 1 with three levels of organic zinc (35, 50 and 65 mg / kg) and two inorganic copper levels (3 , 5:05 mg / kg) and a control diet (50 and 5 mg / kg inorganic zinc and copper respectively), with seven treatments, both experiments with ten repetitions and eight animals each. The basal diet was formulated based on corn and soybean meal. The duration of the experiment lasted 84 days divided into 4 periods of 21 days. Five full mineral premixes and the base of which was composed of sodium selenite, manganese sulfate, calcium iodate, ferrous sulfate and copper sulfate, treatments with organic zinc had zinc proteinate (16% zinc) and the control diet zinc oxide as a zinc source. The variables analyzed were feed intake, laying rate, average egg weight, egg mass, feed conversion per egg mass and per dozen eggs, relative and absolute gem, albumen and shell, in addition to the unit Haugh. It is observed in the first trial that evaluated parameters were not significantly affected by different ratios of organic and inorganic minerals, except for absolute and relative weight of the shell. In the second trial there was no interaction between the levels of zinc and copper, and not between them and the control diet, for any of the parameters analyzed, but when we look at the averages of each variable, we can observe a significant difference for the performance variables feed intake and egg production rate to commercial and total egg relationship and quality variable egg Haugh unit. Thus, it can be concluded that the relationship of 35 mg / kg of organic zinc and 3.5 mg / kg inorganic copper met the performance and quality parameters of Japanese quails eggs in posture.
