Description

[0001] This application claims priority to the prior application filed on May 20, 2026, with application number 202610696019.7, entitled "Complete Pellet Feed for Sheep Fattening and its Preparation Method and Feeding Method", the entire contents of which are set forth in this application. Technical Field

[0002] This invention relates to the technical field of feed, and in particular to a complete pelleted feed for fattening sheep rich in ginsenosides produced using ginseng stems and leaves, and a feeding method thereof. Background Technology

[0003] During ginseng harvesting and processing, ginseng stems and leaves, ginseng residue, and ginseng fruit residue are all byproducts. Ginseng stems and leaves can be further processed to extract ginsenosides. The functional substance in feed supplemented with ginseng is ginsenosides; however, excessive addition of ginsenosides can lead to toxicity, manifesting as over-excitement or digestive disorders. Testing shows that the crude ginseng content (Pr) in ginseng stems and leaves ranges from 6% to 19%, and the total ginsenoside content is above 7.19%. Ginseng stems and leaves can serve as a low-cost, high-quality feed resource, replacing ginseng in feed to produce feed with high ginsenoside content.

[0004] Currently, the extraction and utilization of saponins from ginseng stems and leaves often employs complex processes such as ultrafine grinding and high-efficiency extraction, which are costly and inefficient. However, directly preparing them into feed to create functional feeds with high ginsenoside content represents a new and efficient approach. Adding ginseng stems and leaves to pig and chicken feed leverages their high ginsenoside content to create functional feeds rich in ginsenosides. For example, adding ground ginseng stems and leaves to the basal diet of Jilin Lufeng chickens yields health-promoting chicken and eggs rich in ginsenosides, significantly improving production efficiency. Similarly, adding ginseng extract rich in ginsenosides to laying hens increases egg production. Furthermore, adding ginseng byproducts rich in ginsenosides to the diets of sows further enhances pork quality and promotes pig growth.

[0005] However, ginseng stems and leaves contain 24.1%-41.1% crude fiber (of which neutral detergent fiber accounts for 36.4% and acid detergent fiber reaches as high as 32.2%), which, when added to feed, leads to inefficient absorption by monogastric animals such as pigs and chickens. Therefore, adding ginseng leaves to feed for pigs and chickens often requires complex processing techniques such as ultra-fine grinding, targeted biological fermentation, ultra-high pressure enzyme-assisted crushing, and microfiltration membrane concentration to break down plant cell walls, ferment cellulose, and improve the solubility and absorption efficiency of ginsenoside active ingredients in order to achieve the desired functions.

[0006] The application of ginseng stems and leaves in sheep feed can degrade cellulose in the sheep's rumen due to fermentation, thus promoting the dissolution and absorption efficiency of ginsenoside active ingredients. This is a relatively efficient new method of utilization. However, there are no reports of practical application in the production of ginsenoside-rich functional feeds for sheep fattening, nor are there any reports of research results on ginsenoside-rich sheep feeds.

[0007] Existing research on the use of ginsenosides from ginseng stems and leaves in feed for sheep fattening only describes the physical properties of ginseng powder, namely, a powdered product rich in rare ginsenosides obtained through water or ethanol extraction, purification, concentration, drying, conversion, refining, and drying processes. It does not mention its application in the entire fattening process of sheep, nor does it mention the synergistic effect of the high cellulose content of ginseng stems and leaves. While existing technologies disclose that adding traditional Chinese medicine can regulate the immune system of sheep, they do not study the regulatory effect of ginseng stems and leaves on the sheep's immune system.

[0008] In view of this, the present invention is hereby proposed. Summary of the Invention

[0009] One of the objectives of this invention is to provide a complete pelleted feed for sheep fattening, which can improve the utilization efficiency of ginsenosides, synergistically enhance the immunity of sheep flocks, and increase the average daily weight gain of sheep throughout the entire period.

[0015] Secondly, a method for preparing a complete pelleted feed for sheep fattening as described in any of the above claims includes the following steps: The components are mixed and granulated to obtain the complete pelleted feed for sheep fattening.

[0016] Furthermore, the preparation method of the ginseng stems and leaves includes the following steps: Fresh ginseng stems and leaves are dried in an independent, ventilated environment until they become brittle, then compressed, bundled, and crushed to obtain the ginseng stems and leaves.

[0017] Furthermore, the drying process includes drying by scattering light; Preferably, the ambient temperature for drying is 16℃-20℃; Preferably, the humidity of the drying environment is 35%-40%.

[0018] Furthermore, the air in the drying environment circulates naturally for 24 hours; Preferably, the ventilation volume of the drying environment is 560m³. 3 / h-600m 3 / h.

[0019] Furthermore, the diameter of the shredder screen is 2mm-3mm.

[0020] Thirdly, a method for feeding sheep with complete pelleted feed as described in any of the above claims includes the following steps: The feed shall be given to the lambs once each in the morning, noon and evening.

[0021] Furthermore, the feed is fed at a rate of 1.8%-2.3% of the lamb's body weight per feeding.

[0022] Compared with the prior art, the present invention has at least the following beneficial effects: The complete pelleted feed for fattening sheep provided by this invention, by adding ginseng stems and leaves to sheep feed, can improve the utilization efficiency of total ginsenosides. Ginsenosides from ginseng stems and leaves can enhance the immunity of sheep flocks, especially when combined with red yeast extract, which can further enhance the immunity of sheep flocks and reduce the occurrence of diseases. Ginsenosides from ginseng stems and leaves can increase the average daily weight gain of sheep flocks throughout the entire period, especially when combined with red yeast extract, which can exert an excellent weight gain effect. In summary, the feed of this invention achieves the technical effects of improving the utilization efficiency of ginsenosides, synergistically enhancing the immunity of sheep flocks, and increasing the average daily weight gain of sheep flocks throughout the entire period. Attached Figure Description

[0023] To more clearly illustrate the specific embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the specific embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are some embodiments of the present invention. For those skilled in the art, other drawings can be obtained from these drawings without creative effort.

[0024] Figure 1 A flowchart illustrating the processing of ginseng stems and leaves according to one embodiment of the present invention. Detailed Implementation

[0025] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. 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.

[0026] The existing technology for extracting ginsenosides from ginseng stems and leaves is complex and costly. In addition, due to its extremely high crude fiber content, the digestibility and utilization efficiency of ginsenosides are low in monogastric animals such as pigs and chickens. Directly adding pure ginsenoside powder to feed is not only expensive, but also requires premixing due to the small amount added, which increases the process cost and limits its application.

[0027] Currently, there is no commercial market for full-life fattening feed rich in ginsenosides prepared by adding ginseng stems and leaves; as a special feed resource, ginseng stems and leaves have a low level of utilization in animal husbandry.

[0028] In view of this, the technical solution of the present invention is hereby proposed.

[0029] According to a first aspect of the present invention, a complete pelleted feed for sheep fattening is provided, comprising the following components: Ginseng stems and leaves, red yeast extract, and the basic feed ration for sheep.

[0030] In this invention, adding ginseng stems and leaves to sheep feed can improve the utilization efficiency of total ginsenosides; ginsenosides from ginseng stems and leaves can enhance the immunity of sheep flocks, especially when combined with red yeast extract, which can further enhance the immunity of sheep flocks and reduce the occurrence of diseases; ginsenosides from ginseng stems and leaves can increase the average daily weight gain of sheep flocks throughout the entire period, especially when combined with red yeast extract, which can exert an excellent weight gain effect.

[0031] The red yeast extract in the feed of this invention acts as a natural antioxidant and immunomodulatory substance, which synergistically enhances the activity of ginsenosides, thereby effectively improving immunity, reducing mortality and promoting lamb growth. This achieves the technical effects of improving the utilization efficiency of ginsenosides, synergistically enhancing the immunity of sheep flocks, and increasing the average daily weight gain of sheep flocks throughout the entire period.

[0032] In a preferred embodiment, the mass percentage of ginseng stems and leaves can be 2.4%-3.6%, for example, 2.4%, 2.5%, 2.6%, 2.7%, 2.8%, 2.9%, 3.0%, 3.1%, 3.2%, 3.3%, 3.4%, 3.5%, or 3.6%, but is not limited thereto, and can be further preferably 3%.

[0033] Ginseng stems and leaves, along with specific additive amounts, form a fattening sheep feed rich in ginsenosides. Because it utilizes the natural rumen fermentation tank of ruminants, there is no need for complex processing such as ultra-fine grinding, directional fermentation, and liquid-phase extraction of ginseng stems and leaves, thus achieving efficient absorption and utilization of ginsenosides. At the same time, the high crude fiber content of ginseng stems and leaves, along with the synergistic effect of additives, can stimulate and promote rumen development and regulate the microbial community in sheep.

[0034] Red yeast extract is a mixture of various bioactive components extracted from red yeast fermentation. It contains high levels of β-carotene and β-glucan, and has multiple functions including enhancing immunity, improving gut health, and promoting weight gain. In ruminants, yeast cultures contain special bioactive substances that can improve the rumen environment and regulate the rumen microbiota structure.

[0035] In a preferred embodiment, the mass percentage of red yeast extract can be 1.2%-2.0%, for example, 1.2%, 1.3%, 1.4%, 1.5%, 1.6%, 1.7%, 1.8%, 1.9%, or 2.0%, but is not limited thereto, and can be further preferably 1.5%.

[0036] The synergistic effect of ginseng stem and leaf extract, red yeast extract, and their specific mass ratios is more conducive to fully enhancing the immunity of sheep flocks and significantly increasing the average daily weight gain of sheep flocks throughout the entire period.

[0037] In a preferred embodiment, the basal diet for sheep includes, but is not limited to, the following components: Grass meal, corn, corn husk, soybean meal, wheat bran, premix, stone powder, baking soda, and sodium chloride.

[0038] In a preferred embodiment, the basal diet for sheep comprises the following components by weight percentage: Grass meal 18%-21%, soybean meal 17%-20%, wheat bran 3.5%-5%, premix 1.7%-2.0%, limestone powder 0.6%-0.9%, baking soda 0.65%-0.8%, sodium chloride 0.6%-0.75%, with the remainder being corn and corn husks; The mass ratio of corn to corn shavings can be 2:1, and the grass powder can be Jilin sheep grass.

[0039] According to a second aspect of the present invention, a method for preparing complete pelleted feed for sheep fattening as described in any of the preceding claims is provided, comprising the following steps: The components are mixed and granulated to obtain complete pelleted feed for sheep fattening.

[0040] The preparation method of this invention is simple and inexpensive.

[0041] In this invention, the corn sieve can be made by crushing corn and passing it through a 2mm sieve, then fermenting it with water and lactic acid bacteria liquid; corn, soybean meal and hay are crushed and passed through an 18-mesh sieve, mixed evenly with other materials, then a small amount of water vapor is added and sent to a pellet mill for pelleting, pressing the feed pellets into 4mm diameter pellets, spreading them out to cool naturally for 1 hour after they are made, and then storing them in a dry and ventilated place after cooling.

[0042] In this invention, the addition of red yeast extract to feed requires pre-mixing. This can be done by taking a small amount of crushed and sieved corn flour, diluting it with red yeast extract, stirring it evenly, and then mixing it with other processed formulations for granulation.

[0043] Ginseng stem and leaf powder and red yeast extract were mixed with the basic feed ration for sheep and pelleted to obtain complete pelleted feed for sheep fattening.

[0044] In a preferred embodiment, the method for preparing ginseng stems and leaves (powder) includes the following steps: Fresh ginseng stems and leaves are dried in an independent, ventilated place until they become brittle, then compressed, bundled, and crushed to obtain ginseng stem and leaf powder.

[0045] Adding ginseng stems and leaves directly to feed after coarse processing achieves low-cost and high-efficiency utilization, avoiding the complex chemical process of saponin extraction. The resulting functional feed rich in ginsenosides has significant effects. The powerful rumen of ruminant sheep can directly and efficiently utilize the crude fiber and ginsenosides in ginseng stems and leaves, avoiding the complex pre-processing processes such as fermentation and premixing and the corresponding cost increases when adding feed to monogastric animals.

[0046] A typical preparation method for ginseng stems and leaves (powder) is described below. Figure 1 This includes the following steps: (1) Harvesting: The harvesting time is mainly in early August each year, when the stem and leaf yield is better and the ginsenosides in the stem and leaves are more accumulated. Choose a time when the weather is sunny and the humidity is moderate. Use stems and leaves with dark green leaves and no yellow leaves as the standard. Do not dig up the roots. Harvest each plant only once a year. (2) Drying: The collected ginseng stems and leaves are strung together to a length of 1.6 meters and a weight of 10 kilograms, with each leaf in an independent ventilated state, and then hung on a drying rack 1.9 meters high to dry. Each bunch of ginseng stems and leaves is spaced 0.5 meters apart, and the drying racks are spaced 1 meter apart. The drying racks should be located in a semi-open outdoor shed. Each shed is 5 meters wide, 7 meters long, and 4 meters high. The roof should be shaded, and there should be no direct sunlight inside the shed. Only diffused light should be used for drying. The temperature inside the canopy should be approximately 18°C, with a relative humidity maintained at 35%-40%, and natural air convection ensured for 24 hours, with a ventilation volume of approximately 580 m³ / h. 3 / h, to avoid quality degradation due to slow oxidation of stems and leaves; The entire drying process lasts 38 days, using shade drying throughout. In the end, the weight of each bunch of ginseng stems and leaves is reduced from about 10 jin to about 2 jin, with the leaves being dark green and brittle when lightly squeezed. (3) Bundling: After the ginseng stems and leaves have been dried in the shade, use a pressure of about 800 Pa to bundle them to a size of about 50cm×60cm×40cm. After bundling, the surface of the bundle should be flat, the shape should be standardized, the bundle should have a certain degree of tightness and resilience, the leaves inside should have small gaps, there should be no large number of fragments, and the leaves and stems should be basically intact. After bundling, store in a dry, ventilated, and cool place, with a 10cm wooden board underneath and 10cm away from the wall. Do not stack too many items at once to allow for ventilation. The bundled ginseng stems and leaves are crushed into powder to obtain ginseng stem and leaf powder. The sieve diameter for crushing can be 2mm-3mm, which is beneficial for the subsequent granulation process.

[0047] According to a third aspect of the present invention, a method for feeding sheep fattening complete pelleted feed as described in any of the preceding claims is provided, comprising the following steps: Feed the lambs once each in the morning, noon, and evening.

[0048] In a preferred embodiment, the feed weight per feeding can be 1.8%-2.3% of the lamb's body weight, for example, 1.8%, 1.9%, 2.0%, 2.1%, 2.2%, 2.3%, but is not limited thereto, and can be further preferably 2.0%.

[0049] The present invention will be further illustrated by the following examples. Unless otherwise specified, the materials in the examples are prepared according to existing methods or purchased directly from the market.

[0050] Example 1 A complete pelleted feed for sheep fattening, comprising the following components: Ginseng stems and leaves, red yeast extract, and the basic feed ration for sheep; The weight of ginseng stems and leaves accounts for 3%; The red yeast extract accounts for 1.5% of the total mass.

The preparation method of ginseng stem and leaf powder includes the following steps: (1) Harvesting time is mainly in early August each year, when the stem and leaf yield is better and the ginsenosides in the stem and leaves are more accumulated. Select a sunny and humid time for harvesting, and use stems and leaves with dark green leaves and no yellow leaves as the standard. Do not dig up the roots. Harvest each plant only once a year. (2) The collected ginseng stems and leaves are strung together to a density of 1.6 meters in length and 10 kilograms in weight, with each leaf in an independent ventilated state, and then hung on a drying rack 1.9 meters high to dry. Each bunch of ginseng stems and leaves is spaced 0.5 meters apart, and the drying racks are spaced 1 meter apart. The drying racks should be located in a semi-open outdoor shed. Each shed is 5 meters wide, 7 meters long, and 4 meters high. The roof should be shaded, and there should be no direct sunlight inside the shed. Only diffused light should be used for drying.

After bundling, store in a dry, ventilated, and cool place, with a 10cm wooden board underneath and 10cm away from the wall. Do not stack too many items at once to allow for ventilation. The bundled ginseng stems and leaves are crushed into powder to obtain ginseng stem and leaf powder. The sieve diameter for crushing is 2mm.

[0060] Comparative Example 1 The only difference between this comparative example and Example 1 is that the feed does not contain ginseng stems and leaves, but is supplemented with an equal amount of red yeast extract. Everything else is the same as in Example 1.

[0061] Comparative Example 2 The only difference between this comparative example and Example 1 is that the feed does not contain red yeast extract, but is supplemented with an equal amount of ordinary yeast extract. Everything else is the same as in Example 1.

[0062] Comparative Example 3 The only difference between this comparative example and Example 1 is that the feed does not contain red yeast extract, but is supplemented with an equal amount of ginseng stems and leaves. Everything else is the same as in Example 1.

[0063] Comparative Example 4 The only difference between this comparative example and Example 1 is that the feed contains neither ginseng stems and leaves nor red yeast extract, but is only a basic feed ration for sheep.

[0064] Experimental Example 1 The nutritional composition test results of the feeds in each embodiment and comparative example are shown in Table 1.

[0065] Table 1. Results of nutrient composition analysis for different feeds

[0066] Experimental Example 2 The feeds from each embodiment and the comparative example were fed to lambs to verify the effect of the feeds on improving the immunity of lambs.

[0067] The feeding method is as follows: Feed the lambs three times a day, in the morning, noon and evening. Each feeding should be 2% of the lamb's body weight. Ensure that the lambs have free access to water.

[0068] Measurement indicators: The feeding period lasted 109 days. The serum IgG, IGA and IGM levels were measured after the feeding period ended. The results are shown in Table 2. The diarrhea rate and mortality rate of the sheep flock are shown in Table 3.

[0069] Table 2 shows that, compared with lambs fed the feeds of Comparative Examples 1-4, lambs fed the feeds of Examples 1-9 showed significantly higher serum IgG, IGA, and IGM levels, demonstrating better immunization effects. Meanwhile, Table 3 shows that, compared with lambs fed the feeds of Comparative Examples 1-4, lambs fed the feeds of Examples 1-9 had significantly lower diarrhea rates and mortality rates, demonstrating significantly improved flock immunity. Therefore, it is evident that ginsenosides from ginseng stems and leaves can synergistically enhance flock immunity in combination with red yeast extract.

[0070] Table 2. Serum immune components corresponding to different feeds

[0071] Table 3. Diarrhea and mortality rates in sheep flocks fed different diets.

[0072] Experimental Example 3 The feeds from each embodiment and the comparative example were fed to lambs to verify the effect of the feeds on increasing the daily weight gain of lambs.

[0073] The feeding method is as follows: Feed the lambs three times a day, in the morning, noon and evening. Each feeding should be 2% of the lamb's body weight. Ensure that the lambs have free access to water.

[0074] Measurement time and indicators: Body weight was measured on day 0, day 73 and day 109 of feeding, and the average daily weight gain was calculated as shown in Table 4.

[0075] Table 4 shows that, compared with lambs fed with the feeds of Comparative Examples 1-4, lambs fed with the feeds of Examples 1-9 showed significantly improved average daily weight gain from days 0-73 and from days 73-109. This demonstrates that ginsenosides from ginseng stems and leaves can synergistically enhance the average daily weight gain of fattening sheep during the early and middle stages of growth, in conjunction with red yeast extract.

[0076] Table 4. Average daily weight gain corresponding to different feeds

[0077] In summary, this invention utilizes the high ginsenoside content in ginseng stems and leaves to obtain sheep feed with high ginsenoside content. Simultaneously, the addition of red yeast extract synergistically enhances the immune-boosting and weight-gain-promoting effects of ginsenosides. Furthermore, the high crude fiber content of ginseng stems and leaves in the complete pelleted feed also stimulates and promotes rumen development and regulates the microbial flora in sheep. This overall synergistic effect reduces unfavorable factors for sheep during fattening, thereby achieving the goal of higher weight gain and reduced disease incidence during the sheep fattening period.

[0078] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
