Feed additive for reducing yolk scattering rate of fresh eggs

Abstract

The invention provides a feed additive for reducing the yolk scattering of fresh eggs, which comprises the following components in parts by weight: 20-40 parts of grape seed extract, 20-40 parts of vitamin E, 10-40 parts of folium artemisiae argyi extract, 10-40 parts of beta carotene, 20-40 parts of selenium yeast and 60-80 parts of carrier, wherein the carrier comprises bentonite and rice mill by-product and the weight ratio of the bentonite to the rice mill by-product is 1: 1-3: 1. In each ton of basic feed, the dosage of the feed additive is 200 grams to 600 grams. The feed additive provided by the invention is suitable for all egg-laying poultry, improves the oxidation resistance and antibacterial ability of fresh eggs, can greatly reduce the occurrence rate of yolk scattering of thefresh eggs in the storage period in combination with refrigeration, and the components in the feed additive are all natural plant components or substances allowed to be added into the feed.

Description

technical field [0001] The invention relates to the technical field of laying poultry feeding, in particular to a feed additive for reducing the yolk rate of fresh eggs. Background technique [0002] Fresh eggs will loose yellow after long-term storage, which is caused by the failure of the yolk membrane. The egg yolk membrane is a semipermeable membrane between the protein and the yolk content. Because most of the amino acids in it are hydrophobic, the egg yolk membrane is insoluble in water. The egg yolk membrane can prevent the passage of macromolecules in the egg white and egg yolk, but for water, etc. Both small molecules and ions can pass through, so the egg yolk membrane can effectively prevent the egg white from mixing with the egg yolk, but during storage, the water in the egg white will penetrate into the egg yolk. The yolk membrane is elastic, and the strength of the elasticity will gradually weaken as the egg gets older. After the yolk membrane is broken, the e...

Problems solved by technology

[0005] In the above-mentioned prior art, both the ozone sterilization method and the film coating method have the problems of complicated operation, increased labor and cost, difficult implementation and difficult promotion in practical application. The refrigeration method is currently the most used method with the most ideal effect. However, after the refrigerated period exceeds three months, the yolk rate of the eggs increases significantly, and moldy rot is prone to occur.
