Description

Technical Field

[0001] The present invention relates to a feed additive for optimizing the nutritional components of poultry eggs. Background Art

[0002] China is the world's largest producer and consumer of eggs. As a common source of protein in the diet of Chinese residents, eggs are rich in nutrition and cost-effective. However, at the same time, the egg yolks of poultry eggs such as eggs contain too much cholesterol. The average cholesterol content in each egg is 213 mg, which also limits people's intake of egg products. Especially in recent years, the incidence of cardiovascular diseases such as hyperlipidemia, coronary heart disease, and hypertension in China has been increasing continuously, and patients with these diseases are even more discouraged from consuming poultry eggs.

[0003] With the improvement of people's living standards and the pursuit of a healthy life, the consumption habits of poultry egg products have also changed. People's understanding of eggs has been continuously improved, and more and more people have begun to pay attention to refined nutritional supplements and better tastes. High-end egg products with richer nutritional components and more reasonable nutritional compositions have gradually become the criteria for consumers to choose eggs. Therefore, how to obtain egg products with higher nutritional value by adjusting the feed components of laying hens is an important direction for the development of the egg industry. In this context, developing a feed additive for optimizing the nutritional components of poultry eggs to improve and optimize the nutritional components of poultry eggs has important significance in promoting the development of the poultry egg market.

[0004] Flavonoids are a class of polyphenolic substances with broad-spectrum biological activities; they are widely present in fruits and vegetables and have important effects such as antioxidant, anti-cancer, anti-inflammatory, antibacterial, prevention and treatment of cardiovascular diseases, and immune regulation; research by Yin Jingdong et al. shows that adding daidzein to the diet can reduce the cholesterol content in chicken plasma and liver, and the cholesterol content in egg yolks also decreases accordingly; lotus plants contain various bioactive components such as flavonoids, nuciferine, terpenoids, and polysaccharides, which have many beneficial effects on the functions of animal organisms; adding components such as soy isoflavones and lotus leaves to feed additives can increase the immunity of laying hens and play a regulatory role in lipid metabolism.

[0005] Microalgae cells contain high-value nutritional components such as proteins, lipids, polyunsaturated fatty acids DHA and EPA, polysaccharides, β-carotene, and various inorganic elements (such as copper, iron, zinc, manganese, etc.). Among them, carotenoids such as astaxanthin, lutein, and β-carotene are excellent antioxidants in nature, which can scavenge free radicals in the body and reduce the risk of cardiovascular and cerebrovascular diseases caused by cholesterol. When soy isoflavones, lotus leaves, and microalgae nutritional components are used as feed additives and compounded with natural grains and used in laying hen feed, it can not only increase the nutritional richness of the produced eggs, but also increase the content of bioactive components such as flavonoids and carotenoids in the eggs, while significantly reducing the cholesterol content, optimizing the nutritional structure of the eggs, and meeting people's intake requirements for the nutrition and low cholesterol of egg products. Summary of the Invention

[0006] In view of the problem that people's demand for egg products with a better nutritional ratio, higher nutritional value, and better taste is growing rapidly, a feed additive for optimizing the nutritional components of eggs is provided. Using this additive can increase the content of various nutritional components such as proteins, flavonoids, algal carotenoids, and trace elements in eggs, optimize the nutritional components of eggs, promote the egg production rate of laying hens, and significantly reduce the cholesterol content in egg yolks in a short time. At the same time, it can improve the taste, reduce the fishy smell, and increase the economic value of laying hens.
