Embodiment 1

[0038] The nutrient-enhanced mixed feed was prepared with 1.5% astaxanthin unbroken Haematococcus pluvialis (the content of astaxanthin in the algal powder accounted for 1.5% of the dry weight) algae powder and ordinary compound feed. Among them, the common compound feed accounts for 99.0% of the nutritionally enhanced mixed feed components, and 1.5% Haematococcus pluvialis algae powder accounts for 1.0% of the nutritionally enhanced mixed feed.

[0039] Feed the above-mentioned nutrient-enhanced mixed feed to laying hens according to the conventional feeding method. Generally, the daily feed intake of each hen during the laying period is 2.2-2.3 taels. When the time is extended to the 5th day, its egg yolk color is gradually stabilized as dark red, which is rich in natural astaxanthin (see figure 1 ).

Embodiment 2

[0041] Fresh algae mud of Haematococcus pluvialis (water accounts for about 70%, dry matter accounts for about 30%, astaxanthin content accounts for 0.5% of fresh algae mud, which is about 1.5% of biological dry weight), and ordinary compound feed Mix to prepare nutritionally fortified mixed feed. Among them, the common compound feed accounted for 97.0% of the components of the nutritionally enhanced mixed feed, and the fresh algal mud of Haematococcus pluvialis accounted for 3.0% of the nutritionally enhanced mixed feed.

[0042] The nutrient-enhanced mixed feed obtained above is fed to laying hens according to the conventional feeding method. Generally, the daily feed intake of hens during egg production is 2.2-2.3 taels, and eggs that are basically similar to those in Example 1 are obtained after 4 days, that is, eggs The color of the egg yolk is obviously deepened, which is rich in natural astaxanthin, and with the prolongation of the feeding time, the color of the egg yol...

Embodiment 3

[0044] The above nutrition-enhanced mixed feed is prepared by using the fresh algal mud of Haematococcus pluvialis (wherein the content of astaxanthin accounts for 0.15%) as an enhancer and mixed with common compound feed. Among them, common compound feed accounts for 95.0% of the nutritionally enhanced mixed feed components, while Haematococcus pluvialis algae mud accounts for 5.0% of the nutritionally enhanced mixed feed.

[0045] The nutrient-enhanced mixed feed obtained above is fed to the laying hens according to the conventional feeding method. Generally, the daily feed intake of each hen during the laying period is 2.2-2.3 taels, and the color of the egg yolk begins to deepen on the third day, similar to that of free-range eggs. standard; by 5 days, the color of the egg yolk is deepened to orange, and the egg contains natural astaxanthin; and with the prolongation of the feeding time, the color of the egg yolk gradually deepens, and the color of the egg yolk obtained aft...

Abstract

The invention belongs to the technical field of biology, relates to poultry breeding and particularly relates to nutrient enhanced laying hen feed and application thereof. The nutrient enhanced mixed feed is prepared by taking common compound chicken feed as a foundation, and adding a nutrient enhancer containing rich astaxanthin, wherein the adding amount of the nutrient enhancer containing the rich astaxanthin occupies 0.1%-5.0% of the total mass of the nutrient enhanced laying hen feed. Meanwhile, the feed is used for feeding hens during an egg laying period. The feed sufficiently utilizes the property that haematococcus contains rich natural astaxanthin, and astaxanthin has strong tinting strength and a nutritional health function; a transformation ability of laying hens is effectively used for transferring the natural astaxanthin of the haematococcus and storing the natural astaxanthin into yolk, so that nutrient enhanced functional products, which can be easily and widely accepted by the public, are produced, and requirements on dietary nutrition and health of the public are met.

Description

technical field [0001] The invention belongs to the field of biotechnology and relates to poultry breeding, in particular to a nutrient-enhanced egg feed and its application. Background technique [0002] Egg is a popular food with relatively low price and rich nutrition. It is widely loved by people at home and abroad. It is suitable for all ages, from babies of 4 to 5 months to the elderly. Eggs are composed of eggshell, embryo, thin ribbons, air cells, albumen and yolk. Among them, the egg yolk concentrates the main minerals, vitamins, phospholipids and other important nutrients in the egg. Its composition mainly includes 17.5% protein, 32.5% fat, about 48% water and 2% minerals, and various Vitamins and trace elements etc. [0003] Most of the fat in eggs is concentrated in the yolk, and its fat is mainly monounsaturated fatty acids (the content of oleic acid exceeds 50%), which is beneficial to the prevention of heart disease; all the lecithin in eggs comes from the y...
