Description

Technical Field

[0001] This invention relates to a method for producing eggs rich in various trace elements, belonging to the field of poultry egg production technology. Background Technology

[0002] Zinc, iron, copper, and iodine are essential trace elements for the human body, playing irreplaceable roles in growth and development, immune function, and metabolic regulation. However, the content of these elements in regular eggs is low, making it difficult to meet the daily needs of the human body. Current technologies for increasing the trace element content in eggs mainly suffer from the following drawbacks: Limitations of directly adding trace elements: Although directly adding inorganic trace elements to feed can increase egg content to a certain extent, it can lead to intestinal damage, decreased immunity, and increased mortality in laying hens. Furthermore, laying hens have a low absorption rate of inorganic elements, resulting in resource waste.

[0003] Poor breed compatibility: Different laying hen breeds have significantly different physiological characteristics. Existing solutions are mostly designed for a single breed, and their effectiveness is significantly reduced when applied to other breeds.

[0004] High environmental sensitivity: In non-ideal environments such as high temperature and humidity, low temperature and humidity, or high-density farming, the stress response of laying hens is enhanced, the efficiency of trace element deposition in existing programs decreases by more than 30%, and the egg production rate fluctuates significantly.

[0005] Insufficient nutritional synergy: Existing solutions only focus on micronutrient supplementation, neglecting the overall absorption capacity of the laying hen's body for nutrients, making it difficult to balance micronutrient enhancement with egg production performance.

[0006] Therefore, developing an egg production method that can be adapted to multiple chicken breeds, resist environmental fluctuations, and balance trace element content with breeding efficiency has become an urgent technical problem to be solved in this field. Summary of the Invention

[0007] To address the aforementioned technical problems, this invention provides a method for producing eggs rich in various trace elements, thereby increasing the zinc, iron, copper, and iodine content in eggs, reducing the mortality rate of laying hens, and enabling standardized processes for raw material processing, feed preparation, and drinking water preparation to meet the needs of large-scale farming. It also provides flexible functional component replacement options to adapt to different production costs and market demands.

[0008] The technical solution adopted by this invention to solve its technical problem is: A method for producing eggs rich in various trace elements includes the following steps: S1.

The multi-stage mixing process is as follows: dried grass powder and wolfberry powder are mixed at 200 r / min for 10 minutes; dried jujube powder and dendrobium powder are added and mixed at 200 r / min for 15 minutes; finally, Ganoderma lucidum spore powder is added and mixed at 250 r / min for 20 minutes. The uniformity of the mixture is detected by sodium fluorescein tracer method, and the coefficient of variation is ≤3%. The ultrafine grinding is carried out by an ultrafine grinder with a grinding speed of 4000 r / min and a grinding time of 20 minutes. The particle size after grinding is 100-120 mesh.

[0012] Preferably, in step S2.1, the dosage formula for the Ganoderma lucidum compound powder is as follows: Reishi compound powder dosage (kg) = total water consumption of laying hens (L) / dilution ratio × 0.002 kg / L; The basic nutrient solution must meet the following requirements: Ganoderma lucidum polysaccharide content ≥1.5g / L, total saponin content ≥0.5g / L, pH value 6.0-7.0, microbial indicators comply with GB5749-2022, and the basic nutrient solution must be stored in a refrigerated environment at 4-8℃.

[0013] Preferably, in step S2.2, the dilution ratio is determined according to the age of the laying hens: 30 times for chicks, 40 times for pullets, and 50 times for adult laying hens. The dilution water must comply with GB5749-2022 and be at a temperature of 20-25℃. The multivitamin is composed of 15-20 parts by weight of vitamin A, 20-40 parts by weight of vitamin C, 10-15 parts by weight of vitamin D, and 10-20 parts by weight of folic acid.

When replacing, the mixture of zinc, iron, copper and iodine should be pre-homogenized with 5 times its weight of stone powder before proceeding with the total mixing in step S1.4.

[0015] Preferably, the egg-laying hen-specific pelleted feed obtained in S1 needs to be quantitatively packaged in double-layer plastic woven bags and stored in a cool, dry warehouse with a temperature ≤25℃ and relative humidity ≤60%. The stacking method is quincunx, the storage period is ≤30 days, and the moisture and microorganisms are sampled and tested every 10 days. The functional drinking water of S2 is delivered through food-grade stainless steel pipes and a centrifugal pump. An 80-mesh filter is installed before the pipes. The chicken house uses nipple drinkers. The height of the drinkers is adjusted according to the age of the laying hens. The drinking system is soaked in 0.1% peracetic acid solution for 30 minutes every week and then rinsed with clean water 3 times.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: By supplying both feed and water, the zinc, iron, copper, and iodine content in eggs is increased by 100%-311% compared to traditional methods. The combination of traditional Chinese medicine components and natural Ganoderma lucidum compound powder works synergistically to regulate the physiological functions of laying hens. All steps have clearly defined key parameters and use conventional breeding equipment, which can be directly applied to laying hen farms with a scale of tens of thousands of chickens, and the product quality is highly stable. We offer two functional component options: Ganoderma lucidum compound powder and direct trace elements, to meet different market demands. The core ingredients are mainly traditional Chinese medicine and natural plants, avoiding the stimulation of laying hens by high concentrations of chemical trace elements. The eggs have no chemical residue risk and meet food safety standards. Attached Figure Description

S3. Supply the laying hens with the special pelleted feed for laying hens obtained in S1 and the functional drinking water obtained in S2, and clean up the remaining functional drinking water every 24 hours. Use the basic nutrient solution within 48 hours after preparation.

[0021] In S1.1, the pretreatment includes sorting and removing impurities, washing with clean water, cutting into sections, and then placing them in a drying device for drying. Specifically, preprocessing includes: Sorting and cleaning: Manually remove moldy and insect-infested parts, and clean them for 15 minutes with 20-25℃ clean water in a bubble cleaning machine. The turbidity of the effluent after rinsing is ≤5NTU. Segmentation and Drying: Cut Codonopsis pilosula and Astragalus membranaceus into 3-5cm segments, Glycyrrhiza uralensis into 2-3cm segments, and Poria cocos into 1-2cm granules. Place them in a constant temperature drying room and dry for 24-36 hours until the final moisture content is ≤12%. The specific testing method is to dry at 105℃ to constant weight. Moisture content = (weight before drying - weight after drying) / weight before drying × 100%). Crushing and sieving: A universal crusher is used, equipped with an 80-100 mesh screen, with a rotation speed of 3000-3500 r / min. After crushing, the particles are sieved through a standard inspection sieve, with the proportion of coarse particles ≤2%. Homogenization and storage: Transfer the sieved Chinese herbal powder to a V-type mixer and mix at 200-250 r / min for 15 minutes. The coefficient of variation of the mixing uniformity is ≤5%.

Soybean cake is crushed using a claw mill with an 80-mesh screen at a speed of 3500 r / min to achieve a particle size of 80 mesh. Moisture adjustment: Detect the initial moisture content. Corn 12-14%, wheat 11-13%, soybean meal 10-12%. If it is lower than the target values ​​of 13% for corn, 12% for wheat, and 11% for soybean meal, add water according to the formula: Water addition (kg) = (Target moisture content × Material weight - Initial moisture content × Material weight) / (1 - Target moisture content). Spray evenly with a sprayer, stir for 10 minutes, let stand for 30 minutes, and then test. The error should be ≤ ±0.5%.

Among them, accurate weighing: an electronic balance of model FA2004 is used to weigh each raw material, with an error of ≤±0.5%; The multi-stage mixing process was as follows: dried licorice powder and wolfberry powder were mixed at 200 rpm for 10 minutes; dried jujube powder and dendrobium powder were added and mixed at 200 rpm for 15 minutes; finally, Ganoderma lucidum spore powder was added and mixed at 250 rpm for 20 minutes. The uniformity of the mixture was detected by sodium fluorescein tracer method, and the coefficient of variation was ≤3%. Ultrafine grinding was carried out using an ultrafine grinder at a grinding speed of 4000 rpm for 20 minutes, and the particle size after grinding was 100-120 mesh. Ultrafine grinding and storage: Transfer to an ultrafine grinder and grind at 4000r / min for 20 minutes to achieve a particle size of 100-120 mesh; after sieving, transfer to a nitrogen-filled sealed silo with nitrogen purity ≥99.9% and a temperature ≤25℃ for storage time ≤15 days.

[0026] In S2, the basic nutrient solution preparation method includes: Pre-dissolving: Add 80g of Ganoderma lucidum compound powder to 5L of 30-40℃ water, stir with a magnetic stirrer at 500-600r / min for 5-10 minutes to form a paste-like pre-dissolving solution; Boiling extraction: Pour 35L of clean water into a 50L stainless steel reactor, heat to 80℃ with 15kW electric heating, add the pre-dissolved liquid, stir at 300-400r / min, and boil for 3-5 minutes. Constant temperature extraction: Cool to 80℃±2℃, keep warm for 8 hours, stirring for 5 minutes every hour; Ganoderma lucidum polysaccharide dissolution rate ≥90%; Multi-stage filtration: 80-mesh nylon filter for coarse filtration to remove large particles; 0.45μm polyethersulfone microporous membrane for fine filtration, turbidity ≤1NTU; Quality testing: Ganoderma lucidum polysaccharides ≥1.5g / L, total saponins ≥0.5g / L, pH 6.0-7.0, microbial content conforms to GB5749-2022, store at 4-8℃, use within ≤48 hours.

[0027] In S2.1, the formula for the dosage of Ganoderma lucidum compound powder is as follows: Reishi compound powder dosage (kg) = total water consumption of laying hens (L) / dilution ratio × 0.002 kg / L; The basic nutrient solution must meet the following requirements: Ganoderma lucidum polysaccharide content ≥1.5g / L, total saponin content ≥0.5g / L, pH value 6.0-7.0, microbial indicators comply with GB5749-2022, and the basic nutrient solution must be stored in a refrigerated environment at 4-8℃.

[0028] In S2.2, the dilution ratio is determined according to the age of the laying hens: 30 times for chicks, 40 times for pullets, and 50 times for adult laying hens. The water used for dilution must comply with GB5749-2022 and be at a temperature of 20-25℃. A multivitamin consists of 15-20 parts by weight of vitamin A, 20-40 parts by weight of vitamin C, 10-15 parts by weight of vitamin D, and 10-20 parts by weight of folic acid. The multivitamins need to be pre-dissolved in 30℃ warm water before being added to the diluted nutrient solution. After mixing and homogenization, the coefficient of variation of vitamin C content is ≤3%.

[0029] The Ganoderma lucidum compound powder in S1.2 can be replaced with a mixture of zinc, iron, copper and iodine, and the addition amount of each element per kilogram of diet is: zinc 100-1000ppm, iron 300-500ppm, copper 100-200ppm and iodine 0.05-100ppm. When replacing, the mixture of zinc, iron, copper and iodine should be pre-homogenized with 5 times its weight of stone powder before proceeding with the total mixing in step S1.4.

[0030] Specifically, the raw materials selected are: zinc oxide with a purity of ≥98%, ferrous sulfate with a purity of ≥99%, copper sulfate with a purity of ≥98%, and potassium iodide with a purity of ≥99%. Concentration calculation: Based on the amount added per kilogram of diet, zinc 100-1000 ppm, iron 300-500 ppm, copper 100-200 ppm, iodine 0.05-100 ppm (ppm=1 mg / kg); in one example, 125-1250 g of zinc oxide and 1500-2500 g of ferrous sulfate need to be added per 1000 kg of diet; Premixing: Mix the trace elements with 5 times their weight of stone powder, then transfer to a V-type mixer and mix at 200 rpm for 30 minutes to avoid excessively high local concentrations of trace elements.

[0031] The egg-laying hen-specific pelleted feed obtained from S1 needs to be quantitatively packaged in double-layer plastic woven bags and stored in a cool, dry warehouse with a temperature ≤25℃ and relative humidity ≤60%. The stacking method is quincunx, and the storage period is ≤30 days. Moisture and microorganisms are sampled and tested every 10 days. The S2's functional drinking water is delivered through food-grade stainless steel pipes and a centrifugal pump. An 80-mesh filter is installed before the pipes. The chicken house uses nipple drinkers, and the height of the drinkers is adjusted according to the age of the laying hens. The drinking system is soaked in a 0.1% peracetic acid solution for 30 minutes every week and then rinsed with clean water three times.

[0032] Example 1: A method for producing eggs rich in various trace elements includes the following steps: S1. Preparation of feed specifically for laying hens, including: S1.1 Take 20 parts by weight of Codonopsis pilosula, 20 parts by weight of Astragalus membranaceus, 20 parts by weight of Poria cocos, 10 parts by weight of Shenqu (medicated leaven), 10 parts by weight of Crataegus pinnatifida, and 5 parts by weight of Glycyrrhiza uralensis, and pre-treat them in sequence to obtain Chinese herbal powder. S1.2. Take 20 parts by weight of Ganoderma lucidum compound powder, 85 parts of traditional Chinese medicine powder obtained in step S1.1, 50 parts of staple food powder and 10 parts of malt powder, and mix them in sequence to obtain special pelleted feed for laying hens. S2. Preparation of functional drinking water for laying hens, specifically including: S2.1 Take the Ganoderma lucidum compound powder described in S1.2, add warm water to pre-dissolve it to obtain a pre-dissolved solution, mix the pre-dissolved solution with water and place it in a heating device to boil, then cool it down to 80℃±2℃ and keep it warm for 8 hours, and then perform coarse filtration and fine filtration in sequence to obtain a basic nutrient solution. S2.2. Dilute the basic nutrient solution obtained in step 2.1 with water at a dilution ratio of 30 to 50 times. After dilution, add compound vitamins and mix and homogenize to obtain functional drinking water. The amount of compound vitamins added is 2 to 7% of the total weight of the diluted drinking water. S3. Supply the laying hens with the special pelleted feed for laying hens obtained in S1 and the functional drinking water obtained in S2, and clean up the remaining functional drinking water every 24 hours. The basic nutrient solution is used within 48 hours after preparation.

[0033] Example 2: The difference from Example 1 is that the drinking water in S2 is set to regular clean water, and the Ganoderma lucidum compound powder in S1 is replaced with zinc, iron, copper and iodine, with the following contents per kilogram of diet: zinc 00-1000ppm, iron 300-500ppm, copper 100-200ppm and iodine 0.05-100ppm.

[0034] Example 3: The difference from Example 1 is that the drinking water in step two is set to regular clean water.

[0035] Example 4: The difference from Example 1 is that the feed in step one is set to ordinary feed.

[0036] Five hundred laying hens were randomly divided into five groups, including one control group and three experimental groups. The experimental groups were fed according to the method provided in Example 13, while the control group was fed a basal diet and regular drinking water.

[0037] index control group Example 1 Example 2 Example 3 Example 4 Egg production rate % 91.2 92.8 91.2 90.3 90.5 Zinc content (ppm) 10 25 21 15 17 Iron content (ppm) 12 29 30 14 15 Copper content (ppm) 1.3 5.35 5.22 4.4 5.6 Iodine content (ppm) 4.6 9.05 8.45 6.7 7.3 mortality rate 0.97 0.45 5.51 0.75 0.85 As shown in Table 1, compared with the control group, the egg production rate of Examples 1 to 4 of the present invention was almost the same. The trace elements in Examples 1 and 2 were significantly increased, and the mortality rate of Example 1 was also significantly reduced. However, the mortality rate of Example 2 was also increased. Therefore, although the method of directly adding trace elements can increase the trace element content in eggs, it will increase the mortality rate.

[0038] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
