Abstract
Description
Technical Field
[0001] This invention relates to the field of livestock and poultry feed technology, specifically to a mixed feed additive formulation and feeding method for livestock. Background Technology
[0002] In the aquaculture industry, feed additives are key substances for improving the growth performance of chickens, ensuring their health, and optimizing breeding efficiency. The rationality of their formulation and the scientific nature of their feeding directly affect the breeding results. The following technical problems are commonly found in current chicken feed additives on the market: First, their nutritional components are limited, focusing only on supplementing basic nutrients such as protein and minerals, failing to meet the diverse functional needs of chickens during their growth process. This results in uneven growth rates and limited improvement in production performance. Second, their immune-enhancing effects are poor. Additives lack targeted immune-active components, leading to weaker immune systems in chickens, making them susceptible to common poultry diseases such as intestinal diseases (e.g., salmonellosis, E. coli infection) and respiratory diseases. This not only increases the cost of medication but may also affect product safety. Third, their meat quality improvement effects are insufficient. Existing additives often neglect flavor improvement and meat quality optimization, resulting in chickens with coarse texture and bland flavor, failing to meet consumer demand for high-quality poultry. Fourth, their feeding methods are unscientific. Most farmers use fixed-ratio mixed feeding or uniform feeding throughout the entire process, without adjusting the feeding amount and frequency according to the physiological characteristics of chickens at different growth stages. This leads to low utilization of feed additives, resource waste, and failure to fully realize the functional benefits of the additives.
[0003] To address the aforementioned technical challenges, there is an urgent need to develop a mixed feed additive for chickens that is nutritionally complete, significantly enhances immunity, effectively improves chicken flavor, and is compatible with scientific feeding methods. This would solve the shortcomings of existing technologies and promote the development of the chicken farming industry towards high efficiency, high quality, and green practices. Summary of the Invention
[0004] Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a mixed feed additive formula and feeding method for poultry farming, which achieves balanced nutritional supply, enhances chicken immunity, and optimizes chicken flavor.
[0005] Technical solution To achieve the above objectives, the present invention provides the following technical solution: a mixed feed additive formulation for animal husbandry, comprising core nutrient components, immune-enhancing components, digestive-promoting components, and flavor-improving components in the following weight ratios: Core nutritional components: 5-10 parts calcium sulfate, 3-8 parts methionine, 4-9 parts lysine; calcium sulfate provides calcium and sulfur, promoting bone development and eggshell formation; methionine is feed-grade L-methionine, an essential amino acid that supplements protein synthesis raw materials and improves feed protein utilization; lysine is feed-grade L-lysine hydrochloride, which improves amino acid balance and promotes chicken growth and weight gain.
[0006] Immune-enhancing components: 2-6 parts Astragalus polysaccharide, 1-4 parts Eucommia ulmoides extract, 3-7 parts probiotic compound preparation; Astragalus polysaccharide is feed grade, which enhances the body's non-specific immunity and reduces the risk of infection by regulating the activity of immune cells; Eucommia ulmoides extract is feed grade, which works synergistically with Astragalus polysaccharide to enhance the immune effect, while also having antioxidant effects and delaying the aging of the body; The probiotic compound preparation is composed of Bacillus subtilis and Lactobacillus acidophilus in a weight ratio of 2:1 (Bacillus subtilis regulates the balance of intestinal flora and inhibits the reproduction of harmful bacteria, while Lactobacillus acidophilus promotes the repair of intestinal mucosa and synergistically maintains the health of the intestinal microecology).
[0007] Digestive aid components: 1-3 parts amylase, 1-3 parts phytase, 2-5 parts fructooligosaccharides; the amylase is feed grade, which breaks down starch in feed into absorbable sugars, reducing the digestive burden; the phytase is feed grade, which degrades phytic acid in feed, releasing minerals such as phosphorus and calcium, improving mineral utilization and reducing phosphorus pollution; the fructooligosaccharides are feed grade, which act as prebiotics, promoting the proliferation of probiotics, improving intestinal motility, and enhancing feed digestibility and absorption.
[0008] Flavor-improving components: 10-20 parts of fruit peel residue compound; the fruit peel residue is selected from apple residue, citrus residue, and grapefruit residue, and is used after pretreatment. Apple residue is rich in dietary fiber and malic acid, while citrus residue and grapefruit residue contain natural fruit aroma components and flavonoids. It can not only improve the palatability of feed, but also improve the flavor of chicken meat through the deposition of flavor substances, while supplementing dietary fiber to promote intestinal health.
[0009] The fruit peel residue in the flavor-improving component is selected from apple pomace, citrus pomace, and grapefruit pomace, and is dried, crushed, and passed through an 80-100 mesh sieve. Furthermore, the probiotic compound preparation is composed of Bacillus subtilis and Lactobacillus acidophilus in a weight ratio of 2:1, with a total live bacteria count ≥1×10⁻⁶. 9 CFU / g; Furthermore, it includes the following steps: (1)Raw material pretreatment: Remove impurities from the fruit peel residue in the flavor improvement component, dry it in a hot air drying oven at 60-80°C, turn it over every 30 minutes during the drying process, crush it after drying and sieve it through a 80-100 mesh sieve to obtain fruit peel residue powder; crush calcium sulfate and sieve it through a 60-80 mesh sieve for standby; select the remaining components according to the raw material ratio for standby (no additional pretreatment is required to avoid loss of active ingredients). (2)Component mixing: According to the weight ratio, first add the core nutrient component to a double helix conical mixer and pre-mix it at a speed of 150-200 r / min for 10 minutes, then sequentially add the immune enhancement component and the digestion promotion component, continue to mix for 20 minutes, and finally add the pretreated fruit peel residue powder and mix for 10 minutes. During the mixing process, control the temperature inside the machine ≤40°C to control the temperature and avoid the inactivation of probiotics and the denaturation of enzyme preparations caused by high temperature. (3)Finished product inspection and packaging: Extract samples for testing. If the moisture content ≤8% and the viable count of probiotics ≥1×10 9 CFU / g, it is qualified; use an aluminum foil composite packaging bag for sealed packaging and store it in a cool and dry place at a temperature of 10-25°C and a relative humidity ≤60%.
[0010] Further, in the step (1), the drying time is 2-4 hours.
[0011] Further, the basic feed is a complete feed suitable for the corresponding growth stage, and the mixing ratio, feeding amount and feeding frequency are adjusted according to the different growth stages of chickens as follows: S1. For 1-4 week-old chicks: The mixing weight ratio of the additive to the basic feed is 1:50-1:60. First, pre-mix the additive with 5-10 times the weight of the basic feed, and then add the remaining basic feed and stir; the total daily feeding amount is calculated according to 3-5% of the chicken's body weight and is fed in 3-4 times, once in the morning, middle and evening each day. When the body weight is relatively light, an additional meal in the morning is added (to adapt to the physiological characteristics of the growing chickens with an accelerating growth rate and gradually improving digestive function). S2. For 5-16 week-old growing chickens: Mix the additive with the basic feed and stir for 8-10 minutes; the total daily feeding amount is calculated according to 4-6% of the chicken's body weight and is fed in 2-3 times. S3. For laying hens / broiler fattening stage: The mixing weight ratio for laying hens is 1:70-1:80, and for the broiler fattening stage is 1:65-1:75. Stir for 10 minutes; the total daily feeding amount is calculated according to 5-8% of the chicken's body weight and is fed in 2-3 times. For laying hens, an additional feeding can be added after laying eggs in the morning; ensure drinking water during the feeding process, clean the water dispenser and feeding trough every day (to avoid bacterial growth), and the breeding environment temperature is 18-28°C and the humidity is 50-70%.
[0012] Further, in S1, the stirring time is 5-8 minutes.
[0013] Furthermore, in S2, the weight ratio of the additive to the basic feed is 1:60-1:70.
[0014] Furthermore, in S3, the drinking water temperature is 15-25℃.
[0015] Beneficial technical effects Comprehensive and balanced nutrition to support efficient chicken growth: This invention combines core nutrient components with functional components. Calcium sulfate in the core nutrient components provides calcium and sulfur elements, while methionine and lysine supplement essential amino acids to meet the basic nutritional needs of chicken growth and development. The immune-enhancing, digestion-promoting, and flavor-improving components cover the functional needs during the growth process. The weight proportions of each component work synergistically to avoid the problem of uneven growth rate caused by a single nutrient supply, thus ensuring stable weight gain for chickens.
[0016] Significantly enhances immunity and reduces the risk of diseases in poultry farming: The immune-enhancing components are a combination of Astragalus polysaccharide, Eucommia ulmoides extract and compound probiotics. Astragalus polysaccharide and Eucommia ulmoides extract synergistically regulate the activity of immune cells, while compound probiotics (Bacillus subtilis and Lactobacillus acidophilus) effectively regulate the balance of intestinal microecology, inhibit the reproduction of harmful bacteria such as Salmonella and Escherichia coli, and repair the intestinal mucosal barrier. It strengthens the resistance of chickens from the dual dimensions of immune regulation and intestinal health, significantly reduces the cost of medicines used in poultry farming, and improves the safety of poultry products.
[0017] Improved digestibility and absorption efficiency, saving livestock resources: The digestive aid components include amylase which breaks down starch, phytase which degrades phytic acid to release minerals, and fructooligosaccharides which, as prebiotics, promote the proliferation of beneficial bacteria. The synergistic effect of these three components significantly reduces the digestive burden of feed, increases the absorption rate of nutrients (protein, minerals, and carbohydrates), and simultaneously reduces phosphorus emissions and environmental pollution. Combined with a phased, scientific feeding method, feed utilization is improved, effectively avoiding resource waste and reducing livestock costs compared to conventional fixed-feeding methods.
[0018] Chicken flavor and quality optimization to meet market demand: The flavor-improving components are made from apple pomace, citrus pomace, or grapefruit pomace through special pretreatment. The natural fruit flavor components, flavonoids, and dietary fiber contained in them not only improve feed palatability, but also improve the taste and flavor of chicken meat through the deposition of flavor substances. This solves the problem of coarse texture and bland flavor in chicken meat raised with existing additives, and meets consumers' demand for high-quality poultry meat.
[0019] The preparation and feeding process is scientifically controlled and highly practical: the preparation process adopts a staged mixing process, strictly controlling temperature, rotation speed and time to ensure that active ingredients such as probiotics and enzymes are not lost, and the finished product has a moisture content of ≤8% and a live probiotic count of ≥1×10⁻⁶. 9The feed concentration is CFU / g, with stable and controllable quality. The feeding method is tailored to the physiological characteristics of chickens at different growth stages, with precise adjustments to the mixing ratio, feeding amount, and frequency. It is suitable for the characteristics of chicks with weak digestion, pullets with rapid growth, and laying hens / broilers with high nutritional needs during the fattening period. The operation is simple and easy to implement, and can be directly implemented by technical personnel in the relevant technical field. It is applicable to both large-scale chicken farms and small-scale farming scenarios.
[0020] Green and environmentally friendly with controllable costs, it has both economic and social benefits: the flavor-improving components use agricultural waste (fruit peel residue) as raw materials to achieve resource recycling and reduce raw material costs; the addition of phytase reduces phosphorus emission pollution, which is in line with the development trend of green aquaculture; at the same time, all components are made of feed-grade raw materials and the proportions are scientific and reasonable, which improves aquaculture efficiency while controlling raw material costs, taking into account both economic efficiency and environmental protection, and has broad application value.

[0030] 2. Preparation process Same as Example 1, the finished product has a moisture content of 5.8% and a live probiotic count of 2.1 × 10⁻⁶. 9 CFU / g.
[0031] 3. Feeding method S1 (1-4 weeks old): Additive: Basic feed = 1:55, stir for 6 minutes, the daily feeding amount is calculated as 4% of body weight, and fed 4 times.

[0035] 3. Experimental data (20 weeks) Incidence of intestinal diseases: 2.0%; Average weight at the end of the period: 2.98 kg / animal; Feed conversion ratio: 1.75:1; Chicken flavor score: 91 points (rich citrus flavor).

Experimental Data Laying hens (36 weeks): Egg production rate 91.8%, average egg weight 58.2g, incidence of intestinal disease 2.8%; Broiler chickens (20 weeks): Ending weight 2.83kg, feed conversion ratio 1.85:1, taste score 87; Conclusion: The formula is adaptable to different chicken breeds and has strong versatility.
[0041] Comparative Example 1 (lacking immune-enhancing components, compared with Example 1) Variables: Removed Astragalus polysaccharide, Eucommia ulmoides extract, and probiotic compound preparation; the remaining formula, preparation, and feeding methods are completely consistent with Example 1.
[0042] Experimental data (20 weeks, broiler chickens) Table 1: Comparison between Comparative Example 1 and Example 1
[0043] As shown in Table 1, the immune-enhancing components are the core of reducing disease and improving growth performance; their absence significantly reduces the immunity of chickens.
[0044] Comparative Example 2 (lacking flavor-improving components, compared with Example 1) 1. Variable: Remove the apple pomace compound; the rest of the formula, preparation, and feeding methods are completely consistent with Example 1.
[0045] 2. Experimental data (20 weeks, broiler chickens) Table 2: Comparison between Comparative Example 2 and Example 1
[0046] As shown in Table 2, flavor-modifying components can improve feed palatability and chicken flavor; their absence will prevent the achievement of high-quality poultry meat.
[0047] Comparative Example 3 (conventional fixed feeding, compared with Example 1) 1. Variables: The formula is the same as in Example 1, but the feeding method is changed to "fixed throughout the process": Additive: Basic feed = 1:65, fed twice a day, with the feeding amount calculated as 5% of body weight, without distinguishing between growth stages.
[0048] 2. Experimental data (20 weeks, broiler chickens) Table 3: Comparison between Comparative Example 3 and Example 1
[0049] As shown in Table 3, staged feeding is adapted to the physiological needs of chickens, while conventional fixed feeding leads to a decline in feed utilization and growth performance.
[0050] Comparative Example 1 (lacking immune-enhancing components): This confirms the core value of immune protection. After omitting Astragalus polysaccharide, Eucommia ulmoides extract, and the probiotic compound preparation, the incidence of intestinal disease in broiler chickens surged from 3.0% to 19.2% (an increase of 16.2 percentage points), with 19 chickens developing intestinal infections requiring additional medication. The average weight at the end of the period decreased to 2.35 kg (a decrease of 17.5%), and the feed conversion ratio increased to 2.38:1 (an increase of 25.3%). The data clearly demonstrate that the immune-enhancing components are the "core protective barrier" of this invention—Astragalus polysaccharide and Eucommia ulmoides extract synergistically regulate immune cell activity, while the compound probiotics (Bacillus subtilis + Lactobacillus acidophilus) maintain the balance of the intestinal microecology. The combination of these two components reduces disease risk from the dual dimensions of "immune regulation + intestinal health," avoiding growth stagnation and feed waste caused by disease.
[0051] Comparative Example 2 (lacking flavor-improving components): After removing the apple pomace compound, a key carrier for meat quality optimization, the chicken's palatability score plummeted from 88 to 65 (a decrease of 26.1%), resulting in coarse texture and bland flavor, completely failing to meet the requirements for high-quality poultry meat. Average feed intake decreased from 128g / bird / day to 120g / bird / day (a decrease of 6.3%). Due to decreased feed palatability, chickens' willingness to eat decreased, indirectly leading to a decrease in final weight to 2.62kg (a decrease of 8.1%), and a feed conversion ratio increasing to 2.05:1. Furthermore, the incidence of intestinal diseases increased from 3.0% to 4.8%, confirming that the dietary fiber in the fruit pomace can help maintain intestinal peristalsis and synergize with immune components. The data fully demonstrate that flavor-improving components are not only "meat quality optimizers" but also "palatability enhancers + intestinal health aids," which is key to solving the pain point of "insufficient meat quality improvement" in existing additives.
[0052] Comparative Example 3 (Conventional Fixed Feeding): Demonstrating the Scientific Value of Staged Feeding. The formula was the same as in Example 1, but after adopting the conventional method of "fixed ratio throughout the process + fixed feeding amount," the average weight of broiler chickens at the end of the period decreased to 2.58 kg (a decrease of 9.5%), the feed conversion ratio increased to 2.21:1 (an increase of 18.1%), and the incidence of intestinal diseases increased to 5.5% (an increase of 2.5 percentage points). The core reason is that: the digestion of chicks is weak in the chick stage, and the fixed feeding amount (5% of body weight) leads to indigestion; the nutritional requirements are high in the fattening period, and the fixed additive ratio (1:65) cannot meet the energy supply. This dual contradiction leads to a mismatch between nutritional supply and physiological needs. The data confirms that staged feeding is the key to "making a good formula achieve good results." By adapting to the digestive capacity and nutritional needs of different growth stages, it maximizes feed utilization, avoids resource waste, and solves the pain point of "unscientific feeding" in existing technologies.
