Description

Technical Field

[0001] The present invention relates to the technical field of food production, in particular to a method for producing selenium-rich and high-astaxanthin eggs. Background Art

[0002] As people's living standards improve, their demand for food has shifted from basic sustenance to health and nutrition. However, current egg brands marketed as health-promoting, such as Qianji Multivitamin Selenium-Enriched Eggs, Youzhengkang Algae-Source Astaxanthin Eggs, Xiaoji Small Algae Astaxanthin Eggs, Maiquanquan Algae-Source Astaxanthin Eggs, Huangtian'e Algae-Source Astaxanthin Eggs, Xianrixi Selenium-Enriched Eggs, and Zhengda Selenium-Enriched Eggs, lack both selenium-rich and high-astaxanthin properties. Therefore, there is an urgent need to develop selenium-enriched, high-astaxanthin eggs that simultaneously offer antioxidant, immune-boosting, and cardiovascular health benefits to meet market demand. Summary of the Invention

[0003] In response to the above problems, the purpose of the present invention is to provide a method for producing selenium-rich and high-astaxanthin eggs, which improves the quality and yield of eggs by giving laying hens a reasonably formulated feed, feeding management and lighting control.

[0004] To achieve its purpose, the present invention adopts the following technical solutions: The present invention provides a method for producing selenium-rich and high-astaxanthin eggs, comprising the following steps: Step 1: Select laying hens: Choose healthy, disease-free, and fertile laying hens; Step 2: Feed preparation: The feed formula includes a basic feed and additives; in parts by weight, the basic feed is a premix containing 5 parts of fish meal, 5 parts of shrimp shell meal, 10 parts of seaweed powder and 5 parts of vitamins; the additives are 0.0005-0.001 parts of yeast selenium and 15-30 parts of Haematococcus pluvialis; Step 3: Light control: Keep the light source in the laying hen house evenly distributed, with a light intensity of 10-20 lux; Step 4. Temperature and humidity control: Maintain the temperature of the laying hen house at 13-20°C and the humidity at 50-60%, and clean and disinfect the house regularly; Step 5: Feeding and management: feeding the laying hens with the feed prepared in step 2; Step 6: Collect and disinfect eggs.

[0005] As a further preferred embodiment of the technical solution of the present invention, in step 1, the laying hens are 1-2 years old.

[0006] Preferably, in step 2, the weight portion of Haematococcus pluvialis in the additive is 30 parts.

[0007] Preferably, in step three, the chickens in the growing and laying periods are exposed to light for 16-18 hours per day, and the chickens in the brooding period are exposed to light for 24 hours per day.

[0008] Preferably, in step five, the daily feeding time of the laying hens is divided into 6 times (6:30, 9:00, 12:00, 14:30, 17:00, 19:30), and 2 to 4 times of the feed containing the additive in step two are selected for feeding, and the basic feed is fed for the remaining times; the feeding amount per time is 15 to 40 g / hen.

[0009] The beneficial effects of the present invention are as follows: In the feed formula of the present invention, the basic feed provides the energy and protein required by the laying hens daily to ensure their normal growth and development. Specifically: (1) Fish meal is a high-quality protein source, far higher than most plant protein sources, and can provide the necessary basis for the rapid growth of animals, which is particularly important for the development of young animals; (2) Although the crude protein content of shrimp shell powder is lower than that of fish meal, as an animal protein supplement, it can still provide essential amino acids. In addition, shrimp shell powder is rich in minerals, with high calcium and phosphorus contents, and the calcium-phosphorus ratio is appropriate, which is helpful for bone health, especially suitable for poultry. Moreover, the price of shrimp shell powder is usually lower than that of fish meal. Partially replacing fish meal in livestock and poultry feed can reduce the formula cost; (3) Seaweed powder can promote the improvement of the production performance of laying hens, significantly enhance the nutritional value of eggs. At the same time, components such as alginate and mannitol in seaweed have antibacterial and antiviral activities, which can reduce salpingitis in laying hens and respiratory diseases in broilers. Replacing an equal amount of bran in conventional feed can reduce the feed cost and increase the egg production rate. In addition, the organic minerals (such as calcium, phosphorus, and iodine) in seaweed powder exist in a bioavailable form, which promotes bone development and eggshell formation, and can reduce chondropathy and broken egg rate in laying hens. Moreover, the iodine content of the eggs produced by laying hens added with seaweed powder will increase significantly, deepening the color of the egg yolk, meeting the dual needs of consumers for nutrition and appearance. (4) Adding vitamins to the feed is one of the core measures to ensure animal health, promote growth, and optimize production performance. As essential micronutrients, they participate in the metabolic regulation, immune defense, and physiological function maintenance in animals.

[0010] Among the additives, selenium yeast selenium is the key component to increase the selenium content in eggs. Selenium plays an important role in antioxidant and immune enhancement. Haematococcus pluvialis is the main source to increase the astaxanthin content in eggs. Astaxanthin has strong antioxidant ability and coloring effect, which can significantly improve the nutritional value and commercial value of eggs. There is a mutual promotion effect between the selenium source and the astaxanthin source. Selenium, as an important component of antioxidant enzymes, can enhance the antioxidant ability of the body, while astaxanthin, as a highly efficient free radical scavenger, can further protect cells from oxidative damage. When selenium and astaxanthin act together, they can synergistically enhance the antioxidant defense system of laying hens and improve the overall health level of the body. In addition, selenium and astaxanthin can also promote the absorption and utilization of nutrients by laying hens, thereby improving the feed conversion rate and increasing the egg production and quality.

[0011] 2. The present invention can further improve the quality and yield of eggs, reduce production costs, and meet market demands through reasonable feeding management and light control.

[0012] In summary, through the above-mentioned condition control, the selenium-rich and high-astaxanthin eggs produced by the present invention contain rich nutritional components such as protein, fat, vitamins, minerals, etc., and also have health care functions such as antioxidation, immune enhancement, and cardiovascular protection.

Detailed Description of the Specific Embodiments

[0014] The following combines the drawings to detail the process of the production method of the selenium-rich and high-astaxanthin eggs of the present invention through specific embodiments.

[0015] In specific implementation, the selection of laying hens is crucial. Select healthy, disease-free, and highly reproductive laying hens, aged 1 - 2 years. Laying hens at this age have the strongest reproductive ability and high egg-laying quality. At the same time, feed is an important factor affecting egg quality. Prepare feed containing appropriate amounts of fish meal, shrimp shell powder, seaweed powder, and vitamin premix according to the nutritional requirements of laying hens. These components provide rich nutritional components and trace elements, which help improve the quality and yield of eggs. In addition, adding appropriate amounts of selenium and Haematococcus pluvialis can further enhance the health care function of eggs. Both of these components have functions such as antioxidation, immune enhancement, and cardiovascular protection. Feeding management is also a crucial link. It is essential to keep the chicken house clean, dry, and well-ventilated. At the same time, regularly clean the chicken house and disinfect it to ensure that laying hens live in a healthy environment. In addition, light control is also an important factor affecting the growth and egg-laying of laying hens. Reasonably controlling the light time and intensity according to the growth stage and production requirements of laying hens can promote the growth and egg-laying of laying hens. Finally, the collection, storage, and transportation of eggs are also links that need attention. Collect the eggs laid by laying hens regularly every day, clean, disinfect, and dry them. Keep the temperature suitable and the humidity moderate during storage, and regularly check the egg quality. Keep the container sealed and shock-proof during transportation to prevent breakage and contamination. Through the implementation of the above steps, the present invention can achieve the high-quality and high-yield production of selenium-rich and high-astaxanthin eggs.
