The color of egg yolks ranges from a very pale, powdery yellow to a deep, dark, golden orange depending on a range of influences such as the carotenoid content in the diet, or the age of the hen. At the same time, markets around the globe have very clear preferences as to the desired color. Luckily, farmers who want to meet market demands can rely on Lucantin® Yellow, Lucantin® Red and Lucantin® CX forte for precise results.
Poultry cannot produce carotenoids on their own, which is why poultry feed has to contain them – and why the color of egg yolks depends on their diet. However, it is not only the quantity of pigments that matters but also their bio-availability and color intensity. While C-30 ester (the pigment in Lucantin® Yellow) makes for a rich, golden color, the lutein pigment in marigold products will only lead to a lemony yellow, no matter how much lutein the hens eat. Enhanced bioavailability means not only a more vivid color, it is also more efficient because it produces less waste.
