Zinc copper ratio of Japanese quails diets posture

The objective of this study was to verify the effect of the supplementation of different organic zinc and inorganic copper ratios and to compare the results with the Japanese quail control diet on the productive performance and egg quality. Two experiments were carried out in the experimental area of the Federal University of Espírito Santo, varying the levels of organic zinc and maintaining the recommended copper and the other varying levels of inorganic copper. The experimental period was 84 days. Five mineral premixes were used. Performance and egg quality variables were analyzed. It was first observed that the evaluated variables were not affected significantly by the different mineral relations, except for relative and absolute weight of the bark. In the second test, there was no interaction between the zinc and copper levels, neither between the control and the control diet, for any of the variables observed, when analyzing the individual means, a significant difference was observed for posture rate, commercial and total eggs ratio, feed intake, and in the Haugh Unit. It can be concluded that the ratio of 35mg/kg organic zinc and 3,5mg/kg of inorganic copper met the nutritional requirements of the animals for performance and egg quality.
