Abstract
This study was a continuation of testing natural and synthetic materials in the production of deeply pigmented egg yolk. Thus far ß-apo 8\u27 carotenoic acid ethyl ester (BACE) has been the most efficient pigmenter used, followed by ß-apo 8\u27 carotenal (BAC) and then various alfalfa concentrates, alfalfa or corn gluten meal and marigold meals. There has been a tendency for enhanced yolk color when the synthetic pigmenters were fed with alfalfa, suggesting synergism. This study was therefore conducted to determine if fractions of alfalfa meal with little or no xanthophyll would enhance the utilization of pure pigmenting material
