| Resumo: |
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 chromatography method. Vitamins supplementation did not improve productive performance neither the internal and external quality of the eggs, except for vitamin D supplementation, which increased intake. Incorporation of vitamin A in yolk increased 536.27% at level 30,000 UI/kg, vitamin D increased 13.43% at 1,500 UI/kg and vitamin E increased 479.05% at 600 UI/kg, and these results evidence that the nutritional value of eggs, related to vitamins, can be increased through supplementation of diets for quails.
