This research was carried out at the Amazon Research, Postgraduate and Conservation Center (CIPCA) Poultry Program, of the Amazon State University, Ecuador and aimed to “Evaluate the productive behavior and quality of quail egg (Coturnix coturnix japan) on stage of posture”, for which 72 quail were used, with 69 days (week 10) of age; Each experimental unit (cages) housed 18 quails, in which the variables of posture percentage, egg weight, egg mass, food consumption, food conversion and water consumption as productive indicators were evaluated. For egg quality, 72 eggs were evaluated for 6 weeks, which were measured weekly for shape index, yolk index, egg whites index and Unit Haugh. A Fully Randomized Design (DCA) with four replications was used. The statistical analysis applied was an ANOVA and for the differences the test of Tukey means comparisons was used, at a statistical significance (p <0.05). The productive indicators did not show significant differences for p <0.05 per week, however, among the cages, except for food and water consumption. The ratio of feed conversion and egg mass to percentage of posture was higher at weeks 10, 13 and 15. The quality manifest form indexes from 76.05 to 80%, indicating that they are elliptical and can be accepted in the market. The yolk index and Haugh expressed good quality and freshness of the egg with 0.42 and 81.6% respectively. The quality of the eggs in the different weeks is very good, favoring the commercialization process, when it creates added value to quail products.
