Oropharma Yel-Lux is a natural yellow colorant based on luteine. This dietary supplement intensifies the yellow colour of the plumage and increases disease resistance.
When Yel-Lux is added to the food it is transmitted to the place where the feather is growing and it takes on a more intense yellow colour. The feathers formed retain their colour until the formation of new feathers.
Yel-Lux is not water-soluble and must therefore be mixed in the food.
