Technical Field

The invention belongs to the technical field of animal feed, and particularly relates to an eggshell color improver as well as a preparation method and application thereof.

Background

The color of the eggshell of the poultry is 3, namely green shell, brown shell and white shell. The shell color pigment comprises 3 kinds of protoporphyrin-IX, biliverdin-IX, and zinc chelate of biliverdin. protoporphyrin-IX forms a yellow, pink, yellowish or brownish color, while biliverdin and its zinc chelate cause a blue and green color. The 3 pigments can form different colors from purple blue to olive green according to different proportions. The eggshell is genetically higher in color but is more expressive, as is the brown shell egg, but shows a color that varies from brown to light brown. In the production process of laying hens, the fact that the color of eggshells of the laying hens is light (some eggshells are even white) is often found to influence the sale of eggs, and meanwhile, the eggshells are thin and easy to break and cannot be transported for a long distance, so that great economic loss is brought to breeders.

Improving disease prevention and stress, raising management are main factors for adjusting eggshell color, and nutrition regulation can improve eggshell color to a certain extent, for example, the addition amount of feed is increased by 2-5 times of vitamin A, vitamin D, manganese, zinc and the like compared with the raising standard, but now along with the execution of 2625 bulletin of the Ministry of agriculture and related regulations, the addition amount of nutrients of the category is limited, 2-3% of pine needle leaf powder or 1, 2% of animal protein and 1% of pepper are added, the addition amount is slightly large, the cost is relatively high, and the promotion and application are not facilitated. Therefore, it is significant to develop a feed additive which can improve the color of the eggshell and the quality of the egg, can improve the production performance, has low addition amount and can reduce the breeding cost.
