Effect of Feeding Achiote Seed on Egg-Yolk Pigmentation

Abstract

The yolk-coloring effect of "achiote" seed was investigated. Hens fed a ration supplemented with whole achiote seed laid eggs with deep-colored yolks. The red-orange color that was observed in the egg yolks of the achiote group persisted in both fresh and boiled eggs. Ground achiote seed fed to laying hens did not impart color to the egg yolks when added to the basal ration or when mixed with the drinking water given. The addition of whole achiote seed to the ration fed to laying hens not only colored the egg yolks more deeply, but also increased egg production. Since Puerto Rican consumers prefer eggs with deeper colored yolks this rinding has potential commercial significance.
