| The objective of this study was to evaluate the effects of the inclusion of annato (Bixa orellana L.) and turmeric (Turmeric longa L.) in layer feeds on live performance, egg quality, and yolk pigmentation and depigmentation time. A number of 144 layers were distributed in a completely randomized experimental design, with four treatments with six replicates of six birds each. In the basal diet, sorghum replaced 50% of corn, and was supplemented or not with natural pigments to composse the following treatments: Control (0% pigments), AS (2.0% annato), TR (2% turmeric) and ASTR (1% annato and 1% turmeric). Egg weight (g), egg production (%), egg mass (%), feed intake (g), feed conversion ratio (kg/dz and kg/kg) and mortality were evaluated. The following egg... |
