SUMMARY This study evaluated the effect of turmeric powder (TP) on the productivity and egg quality of quails and on the quality of eggs stored at different temperatures for 7 or 14 d. Quails were distributed in three treatments that consisted of sorghum-based diets with 1.5% and 3% TP or zero TP inclusion, with five replicates for 84 d. Eggs were stored at ambient temperature or refrigerated for 7 or 14 d in a 3 × 2 × 2 factorial arrangement with three TP levels × two storage temperatures (ST) × two storage periods (SP). Inclusion of TP did not affect the performance of the quails or egg quality at 84 d. Interaction SP × ST influenced the height and diameter of yolk and albumen, and the Haugh unit value. Eggs of quails with a diet supplemented with 3% TP and stored for 14 d showed specific gravity similar to the eggs stored for 7 d, despite the TP supplementation. It was concluded that diets with 3% TP did not affect the performance and quality of fresh eggs but improved the quality of eggs stored for 14 d at ambient temperature.
