Subproduto do maracujá em rações de codornas em postura

Abstract

The objective of this experiment was to evaluate the inclusion of passion fruit by-product in the diet of Japanese quails phase on growth performance characteristics and quality of eggs. 280 female quails were used (Coturnix japonica) with 70 days initial age, distributed in five treatments, eight replicates and seven birds per experimental unit. The treatments consisted of five diets with 0, 2, 4, 6 and 8% inclusion by product of passion fruit. They checked the average feed intake (g), feed conversion (g / dz egg g / kg egg), laying percentage (%), average egg weight (g), weight albumen (g), yolk weight (g), specific gravity and egg yolk color (DSM), shell weight (g) and shell thickness (mm). There was no significant difference to the performance characteristics of the variables laying percentage and feed conversion. However, there was a linear decrease in feed intake in addition by product and quadratic behavior where there is optimum level of 2.96% to the weight of the eggs. For the characteristics of egg quality was not identified significant differences in the variables specific gravity, yolk weight, shell weight and shell thickness, but significant effects of treatments for weight albumen and yolk color, which increased staining with the increased by-product in feed. It follows that it is possible to include the passion fruit residue in diets for laying quails phase up to 8%, since most parameters assessed were not significant. Also, the egg yolk color was higher in the 8% level of inclusion of passion fruit residue.
