Problems solved by technology

The decline in the quality of poultry eggs is mainly manifested in the decrease of the smoothness of the eggshell, the decrease of the thickness and hardness of the eggshell, and the easy breakage, especially the chroma (yellow) of the egg yolk becomes lighter and the taste becomes worse, so that the feed-fed eggs lose The Delicacy of Local Eggs in Traditional Egg Farming

Embodiment 1

[0016] The Shangzhuang Breeding Chicken Farm of China Agricultural University conducted experiments on 20-week-old ground chickens. Hens were randomly selected from the large flock and divided into 13 groups A-M, with 45 chickens in each group. A is that the control group is fed with laying hen feed, and B-M group is the feed with mixed additives fed by the test group (wherein, the feed additive is calcium pyruvate and egg shells removed (in order to keep the active ingredients of eggs, through vacuum drying and pulverization) , Feed additives are mixed with laying hen feed when feeding), and fed for 28 days. The ingredients of the additives are shown in Table 1. After four weeks of feeding, 200 eggs were randomly selected for egg quality measurement. The measurement methods and evaluation indicators are as follows. The test data were analyzed by single factor variance of SAS statistical software, and the LSD method was used for multiple comparisons if the difference was sig...

Abstract

The invention discloses a feed additive for improving quality of poultry eggs and egg laying performance. The feed additive consists of pyruvate, calcium salt and poultry eggs of which eggshells are removed, wherein the poultry eggs are subjected to vacuum drying treatment; and the pyruvate and the calcium salt can be calcium pyruvate. When the feed additive is used for feeding the poultry, the feeding amount of the calcium pyruvate is 0.01 to 100 milligrams every day in kilogram by mass, and the feeding amount of the poultry eggs is 22 to 11,000 milligrams every day in kilogram by mass. The feed additive not only improves the egg laying performance of the poultry, but also improves the quality of the eggs, improves the hardness of the eggshells, the color of the yolk and high thick egg white, does not deposit harmful substances in the yolk; improves the utilization rate of feed, reduces the breeding cost, and remarkably increases the economic benefit.

Description

technical field [0001] The invention relates to a feed additive for improving poultry egg quality and egg production performance. Background technique [0002] Traditional feed additives are basically chemically synthesized growth promoters, antibiotics, hormones and other substances, which are prone to produce toxic residues, and are prone to carcinogenic, teratogenic, and mutagenic, which seriously endanger human health, pollute the environment, and cause product quality problems. decline. Therefore, the relevant government departments of various countries in the world have made more and more strict restrictions or regulations on chemical compounds and antibiotic feed additives used in livestock and poultry products. Contaminant feed additives. In recent years, with the continuous improvement of people's living standards, people pay more and more attention to food safety and have higher and higher requirements for quality. Therefore, there is an urgent need to develop a...
