    The present research work determined the effect of the addition of Eucalyptus globulus essential oil on the productive indices and egg quality in Japanese quail (Coturnix japonica). The study is of great importance due to the current search for phytogenic alternatives which allow us to improve productive efficiency and reduce dependence on conventional growth promoters. The study was developed under the line of research oriented to poultry nutrition and production with emphasis on the use of natural additives in minor species. Four treatments were evaluated, a control group without essential oil and 3 levels of inclusion of eucalyptus oil globulus, which are T1 (0.01%), T2 (0.015%) and T3 (0.02%). The variables analyzed were bird production/day, bird/housed production, feed consumption, feed conversion, mortality, egg quality using Haugh units, albumen height, egg weight and shell thickness. All variables were analyzed in 288 birds which were distributed in 9 repetitions of 8 birds each experimental unit, a completely randomized design (DCA) was used. The data were subjected to parametric statistical tests while mortality was evaluated using Kruskal-Wallis. The results showed that the addition of the essential oil did not have a significant value in production, feed consumption, mortality or egg quality; however, the treatment with 0.02% significantly improved feed conversion, demonstrating greater efficiency in feed use, which determines that Eucalyptus globulus essential oil can be a phytogenic alternative to optimize feed efficiency in Japanese quail, without compromising the other productive parameters or egg quality.
