Problems solved by technology

Since calcium carbonate is the main component of eggshells, the current measures to improve eggshell quality are mainly focused on changing the supply mode of calcium, or supplementing vitamin D3 to promote calcium absorption, so as to improve the quality of eggshells. Causing transitional deposition of calcium on the surface of the eggshell, making the eggshell lighter in color

Abstract

The invention belongs to the technical field of feed additives and discloses a microelement eggshell quality improving agent. The microelement eggshell quality improving agent comprises the following components in percentage by mass: 17.65-36.0% of ferrous glycine chelate, 5.81-11.88% of zinc methionine chelate, 3.33-6.80% of copper glycinate chelate, 3.03-6.18% of manganese methionine chelate, 2.50-5.10% of selenium yeast, 1.72-3.52% of basic zinc chloride, 0.86-1.76% of copper chloride hydroxide, 5.00-10.20% of phytase, 0.10-0.20% of ethoxyquin, and 18.38-59.99% of medical stone. The microelement eggshell quality improving agent improves an eggshell ultrastructure comprising internal and external eggshell membranes, a calcified irregular mastoid layer, a palisade layer, a vertical crystal layer and an epidermal layer, the effective regular deposition of calcium carbonate of an eggshell is promoted, the hematopoietic function of a laying hen is improved, and then the quality and the color of the eggshell are further improved.

Description

technical field [0001] The invention relates to a feed additive, in particular to a feed additive for improving eggshell quality. Background technique [0002] At present, with the intensive and large-scale breeding of laying hens, defective eggs caused by eggshell factors such as faded eggs, shellless eggs, soft-shelled eggs, and cracked eggs emerge in an endless stream, bringing huge economic losses. The egg breakage rate of general professional farmers is 2.0-4.5%, and some chicken farms in my country are as high as about 10.0%. The loss rate is about 6.0-10.0%. The economic loss caused by eggshell quality problems in my country is as high as more than 500 million yuan every year. In addition, in the consumption of eggs, the choice of eggshell color has attracted more and more attention from consumers. In a large part of China, perhaps due to the influence of traditional customs, consumers often prefer red (brown) shell eggs with bright colors, so the color of eggshells...
