ABSTRACT Two experiments were conducted to evaluate combinations of different storage periods and temperature of hatching eggs of breeder quails in two stages of the production cycle (24 and 43 weeks) on hatchability, quail neonate quality, and Bursa of Fabricius characteristics. In each experiment, a total of 1.050 Japanese quail eggs were incubated in a randomized block design in a factorial arrangement of 2 × 5 × 2, with two breeder ages (24 and 43 weeks), five storage periods (one, three, six, nine, and twelve days), and two storage temperatures (28 and 14 °C), totaling 20 treatments with 52 eggs each. Quantitative data were subjected to ANOVA and means were compared by Tukey's test. Qualitative data were subjected to Friedman's test. Polynomial...
