Embodiment 1

[0016] Select 200 healthy laying hens at the age of 21 weeks of "Hailan Brown" and divide them into two groups at random, 100 in each group. Compare the above-mentioned feed with the common full-price laying hen feed, and compare the freshness of the eggs produced by feeding the two feeds. Prevalence of period and laying hens. Feeding method: Under conventional feeding environment and conditions, feed each chicken twice a day until 27 weeks.

[0017] Detection method of fresh-keeping period of eggs: 100 eggs produced on the same day in the test group and the control group were placed in the same condition at room temperature and stored away from light, and tested every 10 days within 20 days, and once on the 5th day after 20 days. Random sampling, using the US Department of Agriculture's egg standards to indicate the freshness of eggs --- Hash test method, that is: first break the egg and pour it on a glass plate, while keeping the egg yolk and thick egg white layer intact, av...

Abstract

The invention discloses a laying hen feed capable of prolonging shelf life of eggs. The laying hen feed comprises the following raw materials: by weight, 63-65 parts of corn, 1.2-1.5 parts of calcium hydrogen phosphate, 24-25 parts of soybean meal, 8.5-9 parts of stone flour, 0.015-0.02 part of a vitamin premix, 0.08-0.1 part of a trace element premix, 0.015-0.02 part of compound enzyme for laying hen, 0.015-0.02 part of a microecological preparation, 0.03-0.04 part of tea polyphenol and 0.5-0.6 part of an immunopotentiator. In comparison with a common feed, the feed provided by the invention has the following advantages: eggs of laying hens raised by the use of the feed have smooth and bright eggshells; and shelf life of eggs are prolonged by more than 10 days.

Description

technical field [0001] The invention relates to feed for livestock and poultry, in particular to a feed for laying hens that can prolong the preservation period of eggs. Background technique [0002] Egg is an indispensable public food in people's life, and its protein is rich in nutrition, and it is one of the main foods for the public to consume protein. The lecithin in the egg yolk is the main component of the brain and nerve cells. It can not only improve intelligence, but also acts as an emulsifier in the blood, which can reduce atherosclerosis. There are many types of laying hens, but the main component of the eggshell of all eggs is calcium carbonate, and there are many extremely small pores on the surface. The moisture inside the egg will evaporate from these pores, and oxygen molecules, bacteria, mold, etc. will pass through these pores. Into the inside of the egg, resulting in a decline in the quality of the egg and shortening the shelf life of the egg. At pres...
