A golden yolk can only come from a healthy hen. The hen, the environment and the feed have to work in unison to deliver an attractively pigmented yolk. The DSM Egg Yolk Pigmentation Guidelines provide a practical guide to measuring and improving egg yolk pigmentation.

Achieving desired colour

There are two components of egg yolk pigmentation. The first involves the deposition of yellow carotenoids to create a yellow base - very important for good saturation of the final color. Once the yellow base is established, the addition of the red carotenoid changes the hue to a more orange-red color.

Measuring and monitoring

To succeed in any yolk pigmentation program, it is important to measure. For more than five decades, the DSM’s YolkFan™ has been the standard on yolk pigmentation measuring technology. By using CAROPHYLL® products in conjunction with the DSM’s YolkFan™ score, you can use the least cost formulation to fix the required levels of CAROPHYLL® yellow and CAROPHYLL® red.
