The egg yolk color is formed during the feed intake and the fat-soluble pigments are deposited in the egg yolk during egg formation. The color of the egg yolk is related to the carotenoids, lutein, zeaxanthin, etc. in the feed, but it has nothing to do with the nutritional value of the egg yolk. For consumers, red and yellow eggs are more popular than yellowish eggs. Why egg yolk color is light in yolk is light in color for a number of reasons: The lack of lutein in the diet. Some feedstuffs have low levels of lutein (wheat, barley, rice, or their by-products), and if the feeds are larger in the hens' diets, the yolks are less colored. Diseases such as coccidiosis, cryptospores, malabsorption, or other viral diseases all affect pigmentation. Contamination of feed by mycotoxins can reduce the coloration of the egg yolk. If the storage time is too long, the oxidation of lutein in feed ingredients such as corn and corn gluten meal will gradually reduce the lutein content. The yolk development time is not sufficient. Pigmentation increases with the development of follicles in the ovary, and follicular development (predominantly from small vesicles) takes 10 days, so it takes 10 days for the egg yolk to completely color. It is advisable to feed the pigmented feed for two weeks before egg production so that the color is completely produced. Vitamin A deficiency. Many carotenoids have pro-vitamin A activity. If vitamin A is insufficient, carotenoids will be converted to vitamin A to meet the nutritional requirements of the layer, which will reduce the extent of pigmentation. The correct amount of vitamin A added should balance these two effects. It is recommended that the vitamin A content in the layer chicken feed should not be less than 10,000 IU/kg, and the maximum should not exceed 15,000 IU/kg. How to improve the color of the egg yolk To deepen the color of the egg yolk, in addition to strengthening the feeding and management, eliminating the above factors, you can also take measures such as increasing the color-enhancing substances and supplementing the egg yolk color enhancer. Commercial additives can effectively enhance the degree of coloration to the desired level (Kali-sin Red and Garrison Yellow). Only 30 grams of calendra red per ton of feed is required to increase the egg yolk color of corns fed from RYCF 4-6 to RYCF 11-12. Only yellow yellow corn content in the diet is less than 35% before it is needed. However, if you add 20-40 grams of yellowish yellow can make egg yolk more bright color. In the actual breeding, there are many natural additive feed additives are more commonly used. For example, there are more than 30 varieties, such as calendula, peacock grass, kelp powder, spirulina powder, seaweed powder, honey, ryegrass, leeks, carrots, pumpkins, yellow corn, and cow dung powder. The above recommended feed additives are all natural colorants, safe and non-toxic, and can be safely eaten after the "Red Heart" or "Three Yellow Chicken" produced after feeding.
