| The objective of this research was to evaluate the performance of birds and the quality and enrichment of eggs from quails fed diets supplemented with vitamins A, D and E. Three experiments were performed, one for each vitamin, under completely randomized experimental design, with six replicates and eight birds per plot, totaling 192 quails. Performance of birds was evaluated by the daily feed intake, egg weight, laying percentage (%) and food conversion, per kg and dozen of eggs. It was also evaluated the internal quality (Haugh unit, yolk index and yolk and albumen percentages) and external quality (eggshell percentage, egg specific gravity, eggshell thickness and weight) and the concentration of vitamins in egg yolk by using the high performance liquid... |

| Three experiments with Japanese laying quails were performed aiming to assess the effect of supplementation with minerals in organic form on the egg quality during storage and the deposition of minerals in eggs. The assessments of each experiment were related to one mineral, thus, experiment 1 assessed the supplementation with selenium in 0.35-, 0.70- and 1.05-mg/kg levels of feed; experiment 2, the supplementation with zinc in 50-, 100- and 150-mg/kg levels of feed; and experiment 3, the supplementation of manganese with 60-; 120- and 180-mg/kg levels of feed. All diets were evaluated compared with a control diet without mineral supplementation. Birds were distributed in a completely randomized experimental design, with eight birds per plot and six... |
