Technical Field
The invention relates to the technical field of laying hen mixed feed, in particular to laying hen feed for prolonging the egg preservation period.
Background
Eggs are an indispensable popular food in life of people, are rich in protein nutrition and are one of the main foods for the public to take in protein. Lecithin in egg yolk, which is a main component constituting brain and nerve cells, not only can improve intelligence, but also plays a role of an emulsifier in blood and has a function of relieving atherosclerosis. The egg shells of all eggs are mainly made of calcium carbonate, the surfaces of the eggs are provided with a plurality of extremely fine pores, water in the eggs can evaporate and run off from the pores, oxygen molecules, bacteria, mold and the like can enter the eggs through the pores, the quality of the eggs is reduced, and the preservation period of the eggs is shortened. At present, the quality guarantee period of eggs is not unified in China, the preservation period is relatively longer at low temperature, the best temperature is 4-7 ℃, the quality guarantee period of the eggs is shortened due to high temperature and humidity, and therefore the eggs are eaten within half a month. The shorter fresh-keeping period of the egg products influences the circulation and storage period from egg production to consumption.
Through years of research, the inventor finds that the formula of the laying hen feed has great influence on the shelf life of eggs. The feed formula of the laying hens is different, the structures of the eggshells of the produced eggs are different, and the air permeability of the eggshells is greatly different. Different layer feed affects the fresh-keeping period of eggs by changing the air permeability of the eggshell structure. By improving the feed formula of the laying hens, the research and development of eggs with prolonged preservation period have important practical significance.

Comparative example 6:
a laying hen feed for prolonging the fresh-keeping period of eggs comprises the following components in parts by weight:
65 parts of corn; 25 parts of soybean meal; 10 parts of stone powder; 14 parts of composite trace elements; 7 parts of amino acid; 5 parts of compound vitamin; 6 parts of prebiotics; 4 parts of a compound enzyme preparation; 1 part of amino acid chelated zinc; 5 parts of rangooncreeper fruit; 4 parts of dysosma versipellis; 4 parts of kaempferia galanga; cornel 4 parts; 2 parts of corn; 6 parts of betel nuts; 2 parts of lychee seeds; 10 parts of herba aristolochiae; 5 parts of mulberry leaves; 5 parts of sodium selenite.
The composite trace elements comprise 6 parts of ferric sulfate, 6 parts of iodine chloride, 3 parts of zinc sulfate, 1 part of selenium nitrate, 1 part of calcium hydrophosphate, 3 parts of aluminum nitrate and 3 parts of sodium chloride; the amino acids include 20 parts aspartic acid, 35 parts methionine and 55 parts arginine; the compound vitamin comprises 10 parts of vitamin B1, 6 parts of vitamin B6, 8 parts of vitamin B12 and 5 parts of vitamin D3; the prebiotics are 10 parts of isomalto-oligosaccharide, 10 parts of trehalose and 3 parts of oligochitosan; the compound enzyme preparation comprises 10 parts of polygalacturonase, 3 parts of neutral protease, 5 parts of papain and 6 parts of subtilisin.
Test example:
the detection method of the egg preservation period comprises the following steps: placing 100 eggs produced in the same day of the test group and the control group in the same condition and keeping away from light for storage, detecting every 10 days within 20 days, detecting every 5 days after 20 days, randomly sampling, and adopting an egg product freshness test standard-Ha's test method specified by the American Ministry of agriculture: the egg is broken and poured on a glass plate, under the condition that the yolk and the concentrated egg white layer are kept intact, the middle part of the concentrated egg white layer around the yolk is measured by avoiding a frenum, the height of the egg white is measured by an egg white height measuring instrument at three equidistant points, and the average value of the three points is the egg white height. Then, the Ha's unit is calculated according to the following formula:
hardgrove unit 100. Log (H-1.7W0.37+7.57)
In the formula: h is the concentrated protein height (mm); w is egg weight (gram)
The fresher the egg, the higher the protein height, and the larger the harderian unit.
The storage of the eggs is prolonged along with the time, the concentrated protein in the eggs is diluted by the hydrolysis of the protein, and the Ha's unit is reduced, so that the fresh-keeping period of the eggs is measured. The best Hardgrove unit index of the eggs is 75-80, and the eggs with the Hardgrove unit above 72 can be eaten. Therefore, the Hu's unit 72 is used as the lower limit of the shelf life of edible eggs.
The detection method of the laying hen prevalence rate comprises the following steps: all diseases of the laying hens in the investigation period are uniformly counted as diseased chickens.
The test results are shown in Table 1.
TABLE 1
According to the laying hen feed for prolonging the egg refreshing time, the Ha's unit of the eggs is continuously reduced along with the time lapse in the embodiments 1-3 and the comparative examples 1-6, but the Ha's unit of the feed groups in the embodiments 1-3 is always higher than that of the comparative example group in each stage, and through statistical analysis, when the eggs are stored for 20 days, the Ha's unit of the feed groups in the embodiments 1-3 is obviously higher than that of the feed groups in the comparative examples 1-6; when eggs are stored for 25, 30 and 35 days, the Ha's unit of the feed groups in the embodiments 1 to 3 is remarkably higher than that of the feed groups in the comparative examples 1 to 6, and the Ha's unit 72 is used as the lower limit test standard of the fresh-keeping period of the edible eggs, the test result shows that the fresh-keeping period of the eggs in the control feed group is 35 days, the fresh-keeping period of the eggs in the feed group is 55 to 60 days, and the fresh-keeping period of the eggs in the feed group is improved by 20 to 25 days compared with that of the control feed group.
While embodiments of the invention have been disclosed above, it is not limited to the applications listed in the description and the embodiments, which are fully applicable in all kinds of fields of application of the invention, and further modifications may readily be effected by those skilled in the art, so that the invention is not limited to the specific details without departing from the general concept defined by the claims and the scope of equivalents.
