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 quality parameters were evaluated: specific gravity (SG); yolk, albumen, and eggshell percentages, and yolk color. The treatments did not influence layer performance or egg quality parameters, except for egg production and yolk color. The dietary inclusion of 1% turmeric root and 1% annato seed promoted higher egg production. Diets containing annato resulted in more saturated, more intense, and redder yolk color, with increasing pigment deposition after day 10, with maximum values obtained on day 28. Dried turmeric root did not promote good yolk pigmentation, resulting in higher presence of white in the yolk, which was stabilized on day 4. Three days after pigments were withdrawn from the feeds, yolk color faded in the treatments with annato inclusion. 2011 artículo científico 1516-635X https://www.redalyc.org/articulo.oa?id=179719951002 en http://www.redalyc.org/revista.oa?id=1797 Revista Brasileira de Ciência Avícola application/pdf Fundação APINCO de Ciência e Tecnologia Avícolas Revista Brasileira de Ciência Avícola (Brasil) Num.3 Vol.13 |
