| Resumo: | The aim of this study was to evaluate the effects of symbiotic supplementation on the
performance and quality of Japanese quail eggs. 180 quails at 30 weeks of age were used,
divided into a completely randomized design with five treatments and six replications, with
six birds each, over the course of seventy days. The experimental diets comprised a control
diet without symbiotic containing 22% of crude protein and four other diets containing levels
of 22, 21, 20 and 19% of crude protein, respectively, and with inclusion of 0.25% of
symbiotic. The addition of symbiotic with reduced protein levels had no significant effect
(p>0.05) for the performance parameters. There was a significant difference (p <0.05) for the
yolk color variables, Haugh unit, albumen height, yolk height, yolk index and bark weight. It
is concluded that the symbiotic together with the reduction to 19% crude protein provided
significant gains in egg quality, where the variables outperformed or matched the control diet,
in addition to not impairing the performance of the birds. |
