Egg-chicken feed additive for producing xanthophyll-enriched eggs by using orange peel and preparation method of egg-chicken feed additive

Abstract

The invention discloses an egg-chicken feed additive for producing xanthophyll-enriched eggs by using orange peel. The egg-chicken feed additive is prepared from the following raw materials in parts by weight: 70-72 parts of fermented orange peel powder, 6-8 parts of rice hull powder, 12-14 parts of coccolithophore powder and 8-10 parts of assistant; wherein the assistant comprises solid calcium bisulfate, microcrystalline cellulose and silicon dioxide at the ratio of 1.5:6.7:1.8. A preparation method comprises the following steps: firstly, airing or drying orange peel, rice hull and coccolithophore, respectively crushing into coarse powder with a particle size of 60-80 meshes; in order to make xanthophyll in the orange peel relatively easily absorbed and utilized, fermenting the orange peel powder by using lactobacillus acidophilus, finally uniformly mixing the fermented orange peel powder, the rice hull powder and the coccolithophore powder according to a proportion and then uniformly mixing with the assistant, processing by using a high-energy vibration mill, and making all raw materials generate a solid mechanical and chemical reaction to obtain a finished product. By applying the egg-chicken feed, an egg-chicken is fed by applying the egg-chicken feed, the content of the xanthophyll in yolk can be remarkably improved, and is higher than that of a control group by above 30 percent. According to the egg-chicken feed additive, nutritional conditions of intensively culturing the egg-chicken are improved, the orange peel is comprehensively utilized, waste is changed into valuable, cyclic economy is realized, and the economic benefit is remarkable.

Description

technical field [0001] The invention relates to a layer hen feed additive for producing lutein biologically enriched eggs by using orange peel, and also relates to a preparation method of the layer hen feed additive. Background technique [0002] Lutein is a natural carotenoid, and its anti-oxidation, anti-cancer, anti-aging effects have been widely confirmed. What is more important is that lutein is the main pigment component in the macular area of ​​the human retina. The human body cannot synthesize it by itself and must be obtained from diet ingestion. [0003] There are a variety of health products containing lutein on the market, but due to the current chaos in the production, sales and promotion of health products, consumers prefer to use safer, green, and natural carriers—the less they use capsules, tablets, etc. The dosage form of the drug is easier for consumers to accept. [0004] Laying hens are natural bioreactors. After being purified and filtered by the diges...
