Colours are ever present in the animal kingdom, playing an important biological role. In birds, attraction and mate selection is determined by colours, which indicate good health. These colours come from the animal's diet and are linked to the presence of carotenoids. Carotenoids constitute the largest group of naturally occurring pigments, with much diversity in their distribution, structure and function. They are largely responsible for the variety of yellow to red colours in fruits, vegetables, fungi, feathers of birds, fish flesh, crustaceans and insects, as well as aquatic plants and algae. Carotenoids have always been part of the daily diet of animals and humans. With the development of optimised animal nutrition, the industry created tools to formulate feed to provide animals with required nutrients at the lowest cost. Carotenoids are added to the feed as nutrients that support animal health as well as product quality. New forms of concentrated carotenoids were developed to help feed formulators provide animals with sufficient carotenoids, for the benefit of both the animals and the end consumers. They have become an integral part of the diet of farmed fish and poultry. WELDING supplies essential xanthophylls and carotenoids to create the desired colour.

According to their main indications, different pigments are classified in the EU as carotenoids with the following functions:

  • Substances that add or restore colour in feedstuff
  • Substances which, when fed to animals, add colour to food of animal origin
  • Substances which favourably affect the colour of ornamental fish or birds

In some animal species, carotenoids are also used for other purposes, such as to improve the condition of the immune and reproductive systems.
