Description

Technical Field

[0001] This invention relates to a production method for eggs enriched with unsaturated fatty acids, belonging to the field of poultry farming technology. Background Technology

[0002] With increasing health awareness, the demand for unsaturated fatty acids in food is growing. Unsaturated fatty acids play an important role in human health, including improving blood viscosity, enhancing brain cell activity, and lowering cholesterol and triglyceride levels. As an important source of protein in the daily diet, the unsaturated fatty acid content of eggs has a direct impact on consumers' health. However, traditional egg production methods result in limited unsaturated fatty acid content, which cannot meet the market demand for eggs with high unsaturated fatty acid content. Therefore, developing a production method to increase the unsaturated fatty acid content of eggs is of great significance for improving the nutritional value of eggs and meeting consumers' health needs.

[0003] Currently, the main method to increase the unsaturated fatty acid content in eggs relies on changing the chicken feed formula, such as adding raw materials rich in unsaturated fatty acids, such as flaxseed and fish oil. While these methods can increase the unsaturated fatty acid content in eggs to some extent, they have some drawbacks. First, these methods are costly, increasing the production cost of eggs. Second, these methods are highly dependent on feed raw materials and are greatly affected by fluctuations in raw material supply and prices. In addition, these methods have limited ability to regulate the types and proportions of unsaturated fatty acids in eggs, making it difficult to meet the market demand for eggs with specific types of unsaturated fatty acids.

[0004] Traditional egg production methods cannot effectively increase the unsaturated fatty acid content in eggs, failing to meet market demand for eggs with high unsaturated fatty acid content. Existing feed formulation improvement methods are costly, highly dependent, and have limited controllability, making it difficult to precisely control the unsaturated fatty acid content in eggs. Therefore, developing a low-cost, highly controllable production method that is not limited by raw materials to increase the unsaturated fatty acid content in eggs is of great significance for improving the nutritional value of eggs and meeting consumers' health needs. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a method for producing eggs enriched with unsaturated fatty acids. Through a synergistic system of phased nutritional regulation, functional drinking water assistance, and precise environmental control, the method achieves an Omega-3 content of no less than 0.8g / 100g and a monounsaturated fatty acid ratio of no less than 45% in eggs, with an Omega-3 / Omega-6 ratio of 1:5. This method reduces feed costs by 25% compared to the flaxseed approach, facilitates the procurement of raw materials, maintains a brooding mortality rate of ≤3%, and a shell breakage rate of ≤3% during the laying period, ensuring farming efficiency. The entire process is replicable, and the unsaturated fatty acid content fluctuates by ≤5%, meeting the requirements for large-scale production.

Filter out the residue, let it cool to room temperature, and then dilute it with clean water 50-80 times for daily drinking water. nurturing period, Feed formulation: Mix chicken feed, walnuts, pecans and peanut oil in a weight ratio of 3:1:1:1 before feeding. Drinking water formula: Add Coptis chinensis and honeysuckle to clean water, boil and then keep simmering at 90-95℃ for 3 hours. Filter out the residue, let it cool to room temperature, and then dilute it with clean water 30 to 50 times for daily drinking water. During the egg-laying period, Feed formulation: Mix chicken feed, walnuts, pecans and peanut oil in a weight ratio of 4:2:2:1 and feed them evenly. Drinking water formula: Add Coptis chinensis and honeysuckle to clean water, boil and then keep simmering at 90-95℃ for 3 hours. Filter out the residue, let it cool to room temperature, and then dilute it with clean water 15 to 30 times for daily drinking water. After the egg-laying period reaches its peak, sterilized bone meal is added to the feed. The chicken feed, walnuts, pecans, peanut oil and bone meal are mixed evenly in a weight ratio of 4:2:2:1:1 before feeding.

[0007] Preferably, during the brooding period, the relative humidity of the brooding house is maintained at 60%–70%, active ventilation is maintained at once every 3 hours, the vents of the brooding house are kept half-open, the brooding house is sterilized every 72 hours, and the temperature is controlled as follows: 1–3 days old, 33–35℃; 4–7 days old, 31–33℃; 8–14 days old, 29–31℃; 15–21 days old, 27–29℃; 22–28 days old, 24–27℃; 29–35 days old, 22–24℃; 36 days old to the time of group transfer, 18–21℃.

[0008] Preferably, in the temperature control, the temperature is measured at a distance of 5 cm from the ground or the surface of the mesh bed.

[0009] Preferably, the drinking water formula for the brooding, rearing and laying periods contains compound vitamins, and the amount of compound vitamins added accounts for 2% to 5% of the total amount of drinking water.

[0013] Preferably, during the egg-laying period, when the laying hens reach their peak egg-laying period, sterilized bone meal is added to the feed formula. Chicken feed, walnuts, pecans, peanut oil, and bone meal are mixed evenly in a weight ratio of 4:2:2:1:1 before feeding.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: Through phased and multi-dimensional regulation, a triple synergy is achieved in enriching unsaturated fatty acids, reducing breeding costs, and ensuring the health of laying hens. The specific advantages are as follows: The eggs contain no less than 0.8g of Omega-3 per 100g and no less than 45% of monounsaturated fatty acids, meeting daily health needs. The Omega-3 / Omega-6 ratio is controlled at about 1:5 to avoid the risk of inflammation. At the same time, the increased proportion of monounsaturated fatty acids is suitable for cardiovascular protection scenarios. The raw material supply is stable, and the unsaturated fatty acid content fluctuates by ≤5%, which is better than the existing solutions. By avoiding high-priced flaxseed and fish oil, feed costs are reduced by 25% compared to existing solutions, saving 146,000 yuan per year for 10,000 laying hens. The mortality rate during the brooding period is ≤3%, the eggshell breakage rate during the laying period is ≤3%, and the loss of culled hens and broken eggs is reduced, resulting in an additional annual income of 80,000 yuan. During the brooding period, the combination of traditional Chinese medicine in drinking water and probiotics reduces the incidence of intestinal diseases by 70% and the mortality rate by ≤3%. During the laying period, bone meal supplements calcium and phosphorus, increasing the laying rate to 92%, with eggshell strength not less than 3.5 kg / cm², and extending the laying cycle of laying hens by 1-2 months. Food safety: Made with natural nuts and traditional Chinese medicine, without chemical additives, the drug residue in the eggs is ≤0.01mg / kg, which meets the "National Food Safety Standard for Eggs and Egg Products" (GB2749-2015) and can be promoted as a functional food.

[0015] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the accompanying drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on the structures shown in these drawings without creative effort.

[0016] Figure 1 This is a flowchart of the method of the present invention. Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1 The present invention provides a technical solution: like Figure 1 As shown, a production method for eggs enriched with unsaturated fatty acids targets three stages of egg production: the brooding period (1-35 days old), the rearing period (36-140 days old), and the laying period (141 days old to culling). This method involves coordinated regulation of feed, water, and environment. The specific steps are as follows: Brooding period regulation, that is, from hatching to 35 days of age, lays the foundation for fatty acid metabolism in laying hens: Feed formulation Basic components: 6 parts of complete feed for laying hens, with a crude protein content of 20% to 22% and a metabolizable energy of 11.5 MJ / kg, to meet the growth needs of the chicks; Sources of unsaturated fatty acids: 1.5 parts walnuts, containing 12g / 100g Omega-3 and 25g / 100g monounsaturated fatty acids; 1.5 parts pecans, containing 30g / 100g oleic acid; 1 part olive oil, with an oleic acid content of not less than 75%; 1 part peanut oil, with a linoleic acid content of not less than 40%. Crush the nuts to a size of 1-2mm to prevent chicks from choking. Mix them with olive oil and peanut oil, then add them to the chick feed. Use a twin-shaft mixer at 300r / min for 15 minutes to ensure that the oil evenly coats the feed particles, so that the oil adhesion rate is not less than 90%.

[0019] Drinking water formula Extraction of Chinese medicine: Take 50g of Coptis chinensis and 50g of Lonicera japonica and add them to 10L of water. After boiling, simmer for 3 hours to ensure that the dissolution rate of alkaloids and flavonoids is not less than 80%. After filtering the residue, the mother liquor of Chinese medicine is obtained. Dilution and addition: Dilute the mother liquor with water 50-80 times, and add compound vitamins, accounting for 2-5% of the total drinking water volume, as well as compound probiotic liquid, with a ratio of drinking water to compound probiotic liquid of 80:1; The multivitamin components include: 12 parts vitamin A, 15 parts vitamin C, 10 parts vitamin D, and 4 parts folic acid. Among them, vitamin A can protect mucous membranes, vitamin C can fight oxidation, vitamin D can promote calcium absorption, and folic acid can prevent anemia. The compound probiotic liquid consists of: 6 parts Lactobacillus acidophilus, 2 parts Bifidobacterium and Enterococcus faecalis, 6 parts Bacillus subtilis, and 4 parts Bacillus licheniformis. Among them, Lactobacillus acidophilus can regulate intestinal pH, Bifidobacterium and Enterococcus faecalis can improve fatty acid digestion, Bacillus subtilis can degrade anti-nutritional factors, and Bacillus licheniformis can enhance immunity.

[0020] Environmental control The temperature gradient is precisely controlled according to the chicks' age, and the measurement point is 5cm above the ground or wire mesh, at the chicks' back height. 1-3 days old: 33-35℃; 4-7 days old: 31-33℃; 8-14 days old: 29-31℃; 15-21 days old: 27-29℃; 22-28 days old: 24-27℃; 29-35 days old: 22-24℃; Humidity and ventilation: A relative humidity of 60-70% can prevent respiratory dryness. Actively ventilate once every 3 hours for 10 minutes each time, with a ventilation volume of 0.5 m³ / (h・piece). Keep the vents half open to avoid direct cold air blowing. Sterilization management: Spray sterilization with a 0.3% compound peracetic acid solution every 72 hours, focusing on disinfecting feed troughs and water dispensers, so that the total bacterial count is ≤100 CFU / mL.

[0021] Growth period regulation, specifically for laying hens aged 36-140 days, to enhance their fatty acid synthesis capacity. Feed formulation Composition adjustment: 3 parts of complete feed for chicken growing period, with crude protein content of 16% to 18% and metabolizable energy of 11.2 MJ / kg, 1 part of walnut, 1 part of pecan, and 1 part of peanut oil; Reducing olive oil intake can lower costs, while increasing the proportion of nuts can enhance Omega-3 reserves. Through 140-day rearing, the activity of fatty acid synthase in the liver of laying hens increases by 30%, laying the foundation for enrichment during the egg-laying period.

[0022] Drinking water formula Dilute the mother liquor of traditional Chinese medicine 30-50 times to a concentration of 0.2-0.25g / L to enhance disease resistance. The amount of compound vitamins and probiotics added should be the same as during the brooding period. Daily water intake should be controlled at 100-150mL per bird, adjusted according to age, to avoid excessive water intake that could burden the intestines.

[0023] Environmental control Maintain the temperature at 18-21℃ to reduce energy consumption, keep the humidity at 55-65%, increase the ventilation to 1m³ / (h・animal), and ensure that the ammonia concentration in the enclosure is ≤15ppm to avoid respiratory damage.

[0024] Egg production regulation, specifically targeting and enriching egg production in laying hens from 141 days of age until culling, to ensure egg production. Basic feed formulation: Four parts of complete feed for the laying period, with crude protein content of 18% to 20%, calcium 3.5-4%, and phosphorus 0.6-0.7%, to meet the needs of egg production; two parts of walnuts; two parts of pecans; and one part of peanut oil. The proportion of nuts is increased to 4 parts, which allows unsaturated fatty acids to be absorbed through the oviduct mucosa of laying hens and transported to the yolk, making the fatty acids in the yolk account for more than 85% of the total amount of eggs.

[0025] Optimize peak egg production period, i.e., after the egg production rate of laying hens reaches no less than 85%, by adding bone meal. The feed formula was adjusted to chicken feed: walnut: pecan: peanut oil: bone meal = 4:2:2:1:1, where the bone meal is high-temperature sterilized bone meal with a particle size of 0.5mm and a calcium-to-phosphorus ratio of 2:1. Objective: To replenish the calcium and phosphorus consumed during egg production, prevent eggshell thinning, and at the same time, the phospholipids in bone meal can promote the deposition of unsaturated fatty acids in the yolk, thereby increasing the deposition efficiency by 15%.

[0026] Drinking water formula The mother liquor of traditional Chinese medicine is diluted 15-30 times to a concentration of 0.3-0.4g / L to prevent salpingitis during the egg-laying period. The amount of compound vitamins added is increased to 5%, which can enhance antioxidant capacity and prevent fatty acid oxidation. The proportion of probiotics remains unchanged.

[0027] Environmental control Temperature 20-23℃, temperature difference ≤2℃ / day, light 16 hours / day, light intensity 15-20 lux, promotes hormone secretion, carbon dioxide concentration in the house ≤3000ppm.

[0028] In one embodiment, large-scale breeding was used to verify the results, with 10,000 laying hens for 120 days.

[0029] Brooding period Feed: Mix 600kg of compound feed for chicks, 150kg of walnuts, 150kg of pecans, 100kg of olive oil, and 100kg of peanut oil, and feed 30g / chick three times a day. Drinking water: Boil 5kg of Coptis chinensis and 5kg of Lonicera japonica to make 1000L of mother liquor, dilute it 60 times, and then add 3kg of compound vitamins and 12.5L of probiotic liquid. Drink freely. Environment: Temperature is controlled in a gradient manner, 34℃ for 1-3 day old, and reduced by 2℃ every week; humidity is 65%; ventilation is carried out for 10 minutes every 3 hours; sterilization is carried out once every 72 hours. Results: The mortality rate during the brooding period was 2.8%, which was 65% lower than that of conventional methods, and the average weight of chicks reached the target level in 98% of cases.

[0030] The rearing period, i.e., the laying hen's age of 36-140 days, Feed: 300kg of growing chicken feed, 100kg of walnuts, 100kg of pecans, and 100kg of peanut oil, fed twice a day, 80g / chicken each time; Drinking water: Dilute the mother liquor 40 times, add 3kg of compound vitamins and 12.5L of probiotic liquid; Results: The laying rate of 140-day-old laying hens reached 5%, the intestinal digestibility improved by 20%, and the fat residue in feces was ≤5%.

[0031] The egg-laying period is from 141 to 260 days of age. During the basal period, i.e., 141-180 days old: 400kg of laying hen feed, 200kg of walnuts, 200kg of pecans, and 100kg of peanut oil, fed twice a day, 120g / bird each time; During the peak egg-laying period, i.e., 181-260 days of age: add 100kg of bone meal and adjust the formula to 4:2:2:1:1; Drinking water: Dilute the mother liquor 20 times, add 5 kg of compound vitamins and 12.5 L of probiotic solution; index Results of the Invention Comparison of traditional methods Omega-3 content 0.92g / 100g 0.25g / 100g Monounsaturated fatty acid ratio 48% 29% Omega-3 / Omega-6 Ratio 1:5.2 1:12.8 Eggshell breakage rate 2.5% 11% Egg production rate 92% 86% Feed costs 1.2 yuan / piece / day 1.6 yuan / piece / day Comparative Example 1, The difference from the embodiment is as follows: Brooding period; Chicks are fed a mixture of compound feed, walnuts, and pecans in a weight ratio of 6:1.5:1.5.
