Distillery dried grains with soluble from corn in diet of laying hens

Abstract

The objective of this study was to evaluate the different levels inclusion of corn DDG in the laying hens diet and its effects on the performance, egg quality, yolk pigmentation and economic analysis. A hundred fifty laying hens (Hisex Brown) were distributed in a completely randomized design with five treatments and six replicates, with five birds per experimental unit. The diet formulations met the nutritional requirements of the chickens, using the following treatments: control diet with the inclusion of 0% of DDG; inclusion of 5%, 10%, 15% and 20% of DDG. There was no effect (P> 0,05) on egg quality and performance parameters, the yolk coloring, by the colorimetric spectrum and digital colorimeter (L and a *); there was an effect with DDG inclusion (P <0,05). The corn DDG has a coloring potential in the egg yolk, making it appear more yellow, without influencing the performance and egg quality on laying hens, besides being a more economical product.
