Description

Technical Field

[0001] The present invention relates to the technical field of feed additives, and in particular to the application of silicon-based hydrogen-releasing materials. Background Art

[0002] As demand for poultry products increases, driving the scale-up of the livestock industry, the importance of feed additives becomes increasingly prominent. Traditional feed additives can easily cause heavy metals to accumulate in animal feces, contaminating the soil and entering the food chain. Zinc, for example, can be toxic to microorganisms and aquatic life, and is subject to policy restrictions. As the livestock industry transitions toward a more efficient and environmentally friendly approach, functional feed additives have become a research hotspot. Improving animal health and production performance requires bioactive substances to improve physiological conditions. Most antioxidants indiscriminately scavenge all reactive oxygen species, potentially interfering with normal physiological functions. While hydrogen molecules can selectively neutralize the most toxic hydroxyl radical, existing technologies lack a long-term, sustained-release mechanism, making it difficult to precisely control the kinetics of hydrogen release.

[0003] Chinese patent CN119791199A discloses a feed additive and its preparation method, use, and feed. The feed additive, measured by mass, includes 8 to 12 parts of Chinese herbal medicine, 75 to 85 parts of yeast iron, 55 to 65 parts of starch, and 55 to 65 parts of bentonite. The Chinese herbal medicine is selected from at least one of Rehmannia root, Radix Glycyrrhizae Preparata, Codonopsis pilosula, Cinnamomum cassia, Semen Cannabis, Jujube, Astragalus membranaceus, and Gallnut. The above design can promote the metabolism of skin cells, enhance the barrier function of the skin, and make the skin firmer and smoother. At the same time, nourishing the hair follicles can promote hair growth, making the hair thicker and smoother. However, using only Chinese herbal medicine to exert its effect has complex ingredients and unclear mechanisms of action. The content of the active ingredients of Chinese herbal medicine is significantly affected by the place of production, harvest season, and processing method. It is difficult to ensure the consistency of the efficacy of each batch of products. The reproducibility of the effect of single application is poor.

[0004] Chinese patent CN106756399A discloses a porous metal-ceramic composite material for producing hydrogen-rich water, its preparation method, and application. The composite material has three functions: producing hydrogen-rich water, weakly alkaline water, and micro-molecular cluster water. It can be used in electric kettles, water cups, water purifiers, and humidifiers to produce healthy water rich in hydrogen, which can increase product added value and improve physical health. It can also be applied to aquaculture, feed processing, health care, and beauty industries. However, when applied to feed processing in the form of hydrogen-rich water, hydrogen molecules easily diffuse into the air during processing and storage, resulting in insufficient actual intake and difficulty in meeting the animals' continuous antioxidant needs.

[0005] Chinese patent CN115744816A discloses a solid-state hydrogen-loaded material, its preparation method, and application. The preparation method comprises the following steps: soaking a load shell in an alkaline solution, washing with water, and then drying; crushing the dried load shell to obtain an ultrafine shell powder; heating the ultrafine shell powder at 500-800°C; mixing the shell powder with silica in a mixer; placing the mixed powder in a sealed container, adding purified water, stirring, and sealing; then filling the water with hydrogen, filtering, and naturally drying to obtain a hydrogen storage powder; and placing the hydrogen storage powder in a hydrogen reactor and heating it in a mixed atmosphere of hydrogen and nitrogen to obtain a solid-state hydrogen-loaded material. The solid-state hydrogen-loaded material is used as a cosmetic additive, beverage additive, food additive, feed additive, plant growth regulator, or pharmaceutical additive. However, the application of this solid-state hydrogen-loaded material as a feed additive has been found to be relatively costly, less-than-ideal in efficacy, and limited market acceptance. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide an application of a silicon-based hydrogen-releasing material. The silicon-based hydrogen-releasing material can be used as a poultry feed additive or added to poultry drinking water to prepare hydrogen-rich drinking water, which can significantly increase the egg production rate of laying hens, improve the quality of eggs, and improve the survival rate and meat quality of broilers and ducks, and can effectively increase weight and reduce the feed-to-meat ratio.

[0007] The purpose of the present invention is achieved through the following technical solutions:

[0008] The silicon-based hydrogen-releasing material is used as a poultry feed additive or added to poultry drinking water to prepare hydrogen-rich drinking water;

[0009] The silicon-based hydrogen-releasing material comprises the following raw materials, in parts by weight: 1-30 parts of nano-silicon powder, 23-80 parts of composite alkaline material, 2-10 parts of microporous mineral material, and 1-10 parts of catalyst.

[0010] in:

[0011] The composite alkaline material comprises, by weight, 1-5 parts calcium formate, 5-30 parts calcium carbonate, 5-30 parts magnesium carbonate, and 10-30 parts magnesium oxide. Nano-silicon powder and the composite alkaline material are synergistically mixed to achieve controlled hydrogen release through acid-base regulation.

[0012] The microporous mineral material is at least one of zeolite, sepiolite, medical stone, attapulgite or diatomaceous earth, and its particle size meets the requirements of D90≤150μm, special pore size and adjustment of the proportion of nano-silicon to achieve efficient adsorption-release dynamic balance of hydrogen molecules.

[0013] The catalyst is at least one of magnesium metal, magnesium hydride or calcium hydride, the particle size of the catalyst is 10-200 μm, and the specific surface area is ≥50m 2 / g), breaking through the bottleneck of traditional catalyst agglomeration failure.

[0014] The preparation method of the silicon-based hydrogen-releasing material comprises the following steps:

[0015] (1) ball milling the nano-silicon powder and the composite alkaline material at a material-to-ball ratio of 1:2 at a speed of 200-400 rpm for 3-6 hours to obtain a mixed powder with a particle size of less than 100 μm;

[0016] (2) adding microporous mineral material and catalyst to the mixed powder, and treating the mixed powder by a vibration mixer at a frequency of 20-50 Hz for 30-90 minutes to obtain a mixture;

[0017] (3) Add water to adjust the moisture content of the mixture to 15-50%, and use a granulator to trigger a self-exothermic reaction to form granules, ultimately obtaining particles with a particle size of 0.5-5 mm, namely, the silicon-based hydrogen-releasing material. By controlling the humidity to trigger the exothermic reaction of the material, external energy consumption is reduced by 30-40%.

[0018] The silicon-based hydrogen-releasing material of the present invention has a three-level pore structure, wherein:

[0019] Macropores range from 100-500 nm in diameter, accounting for 40-60% of the total pore volume; mesopores range from 10-50 nm in diameter, accounting for 20-35% of the total pore volume; and micropores <2 nm in diameter, accounting for 15-25% of the total pore volume. The pore connectivity is ≥85%, and the porosity is 28-38%. By optimizing the pore volume ratio, both hydrogen storage capacity and sustained release kinetics are balanced. Microporous mineral materials and catalysts are added to the mixed powder and then processed in a high-energy vibration mixer at a frequency of 20-50 Hz for 30-90 minutes, promoting the formation of the aforementioned tertiary pore structure matrix.

[0020] The application method described in the present invention is specifically: adding the silicon-based hydrogen-releasing material to poultry feed as a feed additive in a certain proportion; or adding the silicon-based hydrogen-releasing material to water to produce hydrogen-rich water, which is used as drinking water for poultry, with the weight ratio of the silicon-based hydrogen-releasing material to water being 1:10-100. The poultry preferably includes laying hens, broiler chickens, and ducks.

[0021] When used as a laying hen feed additive, the added amount is 0.5-1.5‰ of the feed mass.

[0022] When used as a feed additive for broilers and ducks, the added amount is 0.5-2‰ of the feed mass, and is added in a gradient according to the age: during the growth period of broilers and ducks, the added amount is 0.5-1‰ of the feed mass; during the fattening period of broilers and ducks, the added amount is 1-2‰ of the feed mass.

[0023] Preferably, the silicon-based hydrogen-releasing material further comprises a Chinese herbal medicine or prebiotic composition, and the amount of the Chinese herbal medicine or prebiotic composition is 0.05-0.5% of the total mass of the silicon-based hydrogen-releasing material; the prebiotic composition comprises one or more of oligofructose, mannooligosaccharide and yeast β-glucan.

[0024] The present invention utilizes silicon-based materials, which have excellent hydrogen-release potential. Silicon reacts with water to generate hydrogen (Si + 2H2O → SiO2 + 2H2↑). The resulting byproduct, silicon dioxide, is non-toxic and not absorbed by the human body, making it highly safe. Research has shown that nano-silicon powder can efficiently and continuously produce hydrogen in a weakly alkaline environment (e.g., pH = 8.3 in the animal intestine), and the reaction rate is positively correlated with pH.

[0025] In this invention, the material's structural design and sustained-release optimization were optimized. Traditional silicon-based materials (such as silicon nanowires) are often used in energy applications (e.g., photovoltaic hydrogen production), but they suffer from photocorrosion and poor stability. In the field of feed additives, there is an urgent need to develop sustained-release systems with multi-level pore structures to prolong hydrogen release and match animal feeding rhythms.

[0026] This invention integrates interdisciplinary processes: Existing silicon-based material preparation processes (such as ball milling and spray coating) are mostly concentrated in the chemical industry and lack adaptability to industrial feed production. For example, traditional granulation processes are energy-intensive and cannot trigger the self-drying reaction.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. This invention constructs a nano-silicon-mineral synergistic system, introducing a composite microporous mineral material composed of calcium formate, calcium carbonate, magnesium carbonate, and magnesium oxide as a pH-regulating agent. This material, through a dynamic buffering mechanism, precisely maintains the reaction environment within a neutral to weakly alkaline range, triggering the controlled decomposition of nano-silicon powder and achieving sustained and stable hydrogen release. This breakthrough completely changes the inherent dependence of traditional silicon-based hydrogen-releasing materials on strongly alkaline media, effectively reducing the system's corrosiveness and safety risks, and significantly broadening the application boundaries of silicon-based hydrogen storage technology.

[0029] 2. The silicon-based hydrogen-releasing material of this invention utilizes metallic magnesium, magnesium hydride, or calcium hydride catalysts with particle sizes of 10-200 μm, which prevents agglomeration and failure. The material also possesses a three-level pore structure, creating a multi-level pore system consisting of macropores (100-500 nm), mesopores (10-50 nm), and micropores (<2 nm), with a pore connectivity of ≥85%, achieving synergistic optimization of hydrogen storage and sustained release. The material utilizes self-driven drying technology: humidity control triggers the exothermic reaction of the composite mineral (Tmax ≤ 95°C), reducing external energy consumption by 30-40%, making it compatible with feed pelleting equipment.

[0030] 3. Leveraging the hydrogen-releasing properties of silicon-based materials, this invention addresses the core challenges of traditional feed additives in terms of hydrogen-release efficiency, environmental friendliness, and compatibility for industrial production through innovative materials, structure, and process. This technical solution fills a gap in the field of silicon-based functionalized feed additives, aligns with global policies on green farming and carbon reduction, and possesses significant market competitiveness.

[0031] 4. The present invention adopts a cross-species adaptation strategy: based on the differences in the digestive system structure, metabolic rate and nutritional requirements of laying hens, broilers and ducks, a dynamic addition ratio is designed; at the same time, prebiotic synergistic enhancement technology is introduced, and the targeted binding characteristics of prebiotics and nutrients are utilized to optimize the intestinal flora structure, significantly improve the bioavailability efficiency of nutrients, and achieve efficient and precise nutritional supply for different poultry breeding. The silicon-based hydrogen-releasing material of the present invention is used as a poultry feed additive or added to poultry drinking water to prepare hydrogen-rich drinking water, which can significantly improve the egg production rate of laying hens, improve the quality of eggs, improve the survival rate and meat quality of broilers and ducks, and can effectively increase weight and reduce the feed-to-meat ratio.

[0032] 5. The present invention has developed a silicon-based hydrogen-releasing material composed of a variety of low-cost mineral materials. The preparation process is simple and the cost can be saved by about 80% compared with the existing solid-state hydrogen-loaded materials. The effect is significant and can be effectively promoted for large-scale use. DETAILED DESCRIPTION

[0058] Comparative Example 1

[0059] The solid-state hydrogen-loaded material was prepared using the method in Example 1 of Chinese patent CN115744816A.

[0060] 100g of oyster shells were soaked in a potassium hydroxide solution with a concentration of 0.1mol / L for 10h, and then taken out and dried at 50℃. The dried shells were first crushed to 50 mesh and then mechanically ground to 800 mesh to obtain ultrafine shell powder. The ultrafine shell powder was heated at 500℃ for 5h. The dried powder and nano-silica with a size of 50nm were added to the mixer at the same time. The nano-silica accounted for 10% of the total mass.

The volume ratio of nitrogen and hydrogen is 60:40, the heating temperature is 200℃, and the time is 5h to obtain a solid-state loaded hydrogen material.

[0061] The silicon-based hydrogen-releasing materials prepared in Examples 1-3 and the solid-state hydrogen-loaded material prepared in Comparative Example 1 were used as feed additives for experiments.

[0062] 1. Laying Hen Experiment

[0063] At a chicken farm in Yichang, Hunan, 500 laying hens aged 300-400 days with similar egg production rates were randomly divided into five groups. The control group was fed a basic feed, while the experimental groups were fed a basic feed supplemented with feed additives (see Table 1). Zhengda Feed was used as the basic feed. Experimental Groups 1-3 used the silicon-based hydrogen-releasing materials prepared in Examples 1-3, while Experimental Group 4 used the solid-state hydrogen-loaded material prepared in Comparative Example 1.

[0066] The egg production rate was calculated and the average egg weight was measured. The specific indicators measured were: (1) Egg production rate of laying hens: Eggs were collected once every afternoon at 6:00 PM, the total number of eggs laid was collected, and the average daily egg production rate was calculated. (2) Average egg weight. The test results are shown in Table 2.

[0069] Fifty eggs from each of the experimental and control groups were sampled and sent to a third party for testing of protein, calcium, folic acid, and silicon nutrients. The results are shown in Table 3.

[0074]

[0075]

[0076] It can be seen from the above tests that the silicon-based hydrogen-releasing material of the present invention can be used as a feed additive in combination with a basic feed to feed laying hens, which can significantly improve the egg production rate of laying hens and significantly increase the calcium, silicon, protein and folic acid content of eggs, thereby significantly improving the quality of eggs. In addition, the main components of the additive are mineral materials such as nano-silicon, calcium carbonate, and magnesium oxide, and the by-product is inert silicon dioxide (not absorbed), which meets the feed safety standards. The third-party heavy metal-free inspection of the eggs has confirmed that no harmful components are introduced. According to the experimental results, it can be seen that the effect of Comparative Example 1 is general. In Examples 1-3, as the content of nano-silicon powder increases, the effect increases positively, reaches a peak at 10 parts, and continues to increase. For example, the effect of Example 3 does not increase significantly. According to the foraging and emptying and excretion rules of chickens (4-8 hours), the content of the silicon-based material in Example 2 is the best, so only the formula of Example 2 is used for broiler chickens and ducks.

[0077] 2. Broiler chicken experiment

[0078] 400 healthy AA broiler chicks with normal feed intake and uniform weight were randomly divided into four groups. The control group was fed a basal feed, while the experimental groups were fed a basal feed supplemented with feed additives (see Table 5). Zhengda Feed was used as the basal feed. Experimental Groups 1 and 2 used the silicon-based hydrogen-releasing material prepared in Example 2, while Experimental Group 3 used the solid-state hydrogen-loaded material prepared in Comparative Example 1.

[0079] Table 5 Dosage of feed additives

[0080]

[0081] The results of statistics on age at market, survival rate, average market weight and feed-to-meat ratio are shown in Table 6.

[0082] Table 6 Results of age at market, survival rate, average market weight and feed-to-meat ratio

[0083] Group Age at market (days) Survival rate (%) Average slaughter weight / kg Feed-to-meat ratio Experimental Group 1 41 96 2.57 1.47 Experimental Group 2 41 96 2.73 1.42 Experimental Group 3 41 96 2.52 1.51 control group 42 95 2.51 1.53

[0084] The amount of feces was counted and the odor was evaluated. The results are shown in Table 7.

[0085] Table 7 Feces volume and odor evaluation results

[0086] Group Record age (days) Fecal volume (g) Odor rating (1-10, the larger the number, the stinkier) Experimental Group 1 30 750 5 Experimental Group 2 30 720 4 Experimental Group 3 30 782 8 control group 30 887 9

[0087] The above experiments show that hydrogen molecules selectively neutralize the most toxic hydroxyl radical (·OH) to increase the survival rate, and hydrogen molecules can effectively regulate the intestines, reduce the feed-to-meat ratio of broilers, significantly reduce the amount of feces, and reduce the odor of feces.

[0088] 3. Meat duck experiment

[0089] 500 healthy ducklings with normal feed intake and uniform weight were selected and randomly divided into five groups. The control group drank normal water, while the experimental groups drank water soaked with silicon-based hydrogen-producing materials. The addition amounts are shown in Table 8. Experimental Groups 1-2 used the silicon-based hydrogen-releasing material prepared in Example 2, Experimental Group 3 used the silicon-based hydrogen-releasing material prepared in Example 4, and Experimental Group 4 used the solid-state hydrogen-loaded material prepared in Comparative Example 1.

[0092] Ten meat ducks were randomly selected from the experimental group and the control group, and their average weights were compared at 7 days, 14 days, 21 days, 28 days, and 36 days of age. The comparison results are shown in Table 9.

[0093] Table 9 Comparison results

[0094]

[0095]

[0096] Experimental comparison shows that drinking water prepared from silicon-based hydrogen-releasing materials has a significant increase in weight.

[0097] The survival rate, average slaughter weight and feed-to-meat ratio were statistically analyzed and the results are shown in Table 10.

[0098] Table 10 Survival rate, average slaughter weight and feed-to-meat ratio

[0099] Group Survival rate (%) Average slaughter weight / g Feed-to-meat ratio Experimental Group 1 98 2910 1.77 Experimental Group 2 98 2950 1.74 Experimental Group 3 99 2961 1.73 Experimental Group 4 98 2886 1.80 control group 97 2870 1.83

[0100] It can be seen from Table 10 that the survival rate of meat ducks drinking hydrogen-rich water prepared by the material of Example 2 is improved, the slaughter weight of experimental group 1 is 40g higher, the slaughter weight of experimental group 2 is 80g higher, the slaughter weight of experimental group 3 is 91g higher, and the slaughter weight of experimental group 4 is 16g higher; the feed-to-meat ratio of experimental group 1 decreases by 0.05, the feed-to-meat ratio of experimental group 2 decreases by 0.09, the feed-to-meat ratio of experimental group 3 decreases by 0.1, and the feed-to-meat ratio of experimental group 4 decreases by 0.03, further illustrating that silicon-based hydrogen-releasing materials are more suitable for the field of feed additives.

This will be readily apparent to those skilled in the art. Therefore, such modifications or improvements, without departing from the spirit of the present invention, are considered within the scope of the present invention.
