Poultry Feed Additives: 8 Natural Materials That Give Yellow Yolk Color

Parts of the Non-nutritional components of poultry diet are the poultry feed additives. They are added to poultry feeds to improve feed performance and animal well-being. Poultry feed majorly contains cereal and legumes; these two components take a larger percentage, like 95%, of the total feed formulation. Others ingredients are vitamins and minerals; they all play significant roles in poultry well-being.

Feed additives in animal nutrition usually take a very small percentage, less than 1%, of the feed composition. They play notable roles in poultry diet; such as attaining consumers’ choice of product and improving the performance of the animal by boosting the immune system and protecting the animals from various infections.
There are different examples of feed additives for poultry, they are antibiotics, antioxidants, pigmenters etc. In this article, we shall discuss pigmenters and their relevance in poultry nutrition.


Importance of Pigmenters as poultry feed additives

Pigmenters are examples of feed additives for poultry that enhance the quality of the chicken’s egg yolk color. Egg yolk colors are almost completely dependent on the feed served; yolk color is one of the internal qualities of an egg. Egg with bright yellow yolk is more preferred to egg with orange or pale color yolk.

The bright yellow color of the yolk is due to the presence of xanthophyll pigment in the diet. It can be sourced naturally or artificially, depending on the preference of the farmer. Yellow maize is a good source of xanthophyll pigment in poultry diet.

Take a look at this:

Yellow maize contains this pigment; when fed to poultry birds, it gives the yolk a bright yellow color. But wheat does not have this pigment. Hence, the use of wheat in a poultry diet requires the inclusion of pigmenters as additives to ensure the bright yellow color is achieved.

Poultry feed additives are classified into two; namely:

  • Natural or organic feed additives
  • Artificial or synthetic feed additives.

The natural poultry feed additives are those ones that are naturally present in feedstuff, like the presence of xanthophyll in yellow maize. If this maize is used as a whole source of energy in the poultry diet, then, the inclusion of pigmenter in the feed may not be necessary. However, if other energy feedstuff like wheat is used, then pigmenters can be added to the feed.

Synthetic feed additives are those materials developed to improve the performance of the diet and animal fed. They are real feed additives. They are not sourced in the feedstuff but synthesized in the laboratory and certified for animal use. Example of synthetic pigmenter is canthaxanthin. This can be added to poultry diet to improve the egg yolk color.

However, people are becoming more conversant with what they consume. Everyone craves organic nutrition; as an organic poultry farmer, instead of adding the synthetic pigmenters to your poultry diet, you can add any of the below materials as organic poultry feed additives to give you a bright yellow yolk color. Various researches have proven that they have pigmenting property in them.

  • Sunflower Petals
  • Marigold leaves
  • Alfalfa
  • Orange peels
  • Algae
  • Carrot
  • Annatto Seed
  • Chili pepper.

These are examples of feed additives for poultry with the ability to enhance a bright yellow color in egg yolk. They are natural and have no side effects; unlike the synthetic ones that tend to have residual effects upon consumption. These materials are applied in dried form with no limitation since they are organic in nature. They give better yolk color compare to the synthetic ones.

  1. I have never seen my chickens eat a citrus peel.. nor carrots. Maybe the addition of some more run space (chicken tractor etc) would allow for truly natural bright yellow yolks, and tastier eggs to boot. Grass, bugs and plants on the fringes of a backyard are favorites here with my ladies. Thanks for the blog. Good things for all poultry owners to think about.
