Feed additive capable of improving yolk color and egg quality

Abstract

The invention belongs to the field of animal feeds, and particularly discloses a feed additive capable of improving yolk color and egg quality. The feed additive capable of improving the yolk color and the egg quality is prepared from the following active components in parts by weight: 50-150 parts of thallus laminariae powder, 0.002-0.006 part of lactoflavin, 50-150 parts of chili meal, 0.0005-0.005 part of xanthophyll, 50-150 parts of southernwood powder, 50-150 parts of dried marine algae powder and 50-150 parts of orange peel powder. The feed additive capable of improving the yolk color and the egg quality is reasonable in formula, and simple to prepare, can notably increase the egg laying rate of egg layers, and can prolong the peak period of egg laying. After laying hens eat the feed additive, the yolk color can be obviously improved, the egg weight is increased, a cholesterol content in yolk is reduced, the immunity of the laying hens is improved, the color of eggshells is deepened, the egg destruction rate is reduced, and the material egg ratio is reduced; after the laying hens eat the feed additive, the situation that toxin is remained in the bodies and eggs is avoided, the commodity value of the eggs is increased, and the market competitiveness is improved; besides, the feed additive improves the economic benefits for breeding households.

Description

(1) Technical field [0001] The invention belongs to the technical field of animal feed, in particular to a feed additive for improving egg yolk color and egg quality. (2) Background technology [0002] Eggs are a common food on people's daily tables. In the pursuit of high quality of life, people pay more and more attention to their quality. Eggs with darker yolk, low cholesterol, and high polyunsaturated fatty acid content are favored by people. . In daily life, when people buy eggs, they prefer eggs with yellower and darker yolks, and the color of yolks is formed by the deposition of carotenoids such as lutein, zeaxanthin and carotene into the yolk during egg formation, and the chicken itself does not synthesize them. The ability of these pigments can only be ingested through external food. In the modern intensive breeding mode, the amount of natural food that can improve and increase the yellowness of eggs in the feeding of laying hens is greatly reduced, resulting in t...

AI Technical Summary

Problems solved by technology

Adding red pepper powder to diet can improve egg production performance, egg yolk color grade, and reduce cholesterol content in blood and eggs. Therefore, it is urgently necessary to study a feed additive that improves egg yolk color and egg quality through reasonable and scientific addition and deployment based on the selection and effective addition of various raw materials and additives. On the basis of cost, further meet the market demand, enhance the market competitiveness of eggs and improve their commercial value, and promote human health
