Description

Technical Field

[0001] This invention belongs to the field of poultry farming technology, specifically relating to a breeding feed for geese and its application. Background Technology

[0002] Breeding goose farming is the core foundation of the goose industry's development. Breeding goose farming technology can fundamentally meet diverse market demands, create considerable economic benefits, and is a key pillar for promoting the industry's sustainable development. However, currently, the breeding goose farming sector, especially the breeding technology of Zhejiang East White geese, faces significant bottlenecks in production efficiency and cost pressures. Under the conventional mixed-species rearing model with a male-to-female ratio of 1:5, the average annual egg production of breeding geese is low, only 28 eggs / bird, accompanied by a mortality and culling rate as high as 12%. Furthermore, the breeding process of Zhejiang East White geese is highly dependent on complete feed. During the breeding period, the average daily consumption of complete feed reaches 0.5 catties / bird, and the unit price of feed generally remains at 1.3 yuan / catties, resulting in persistently high breeding costs. More fundamentally, the current dietary nutritional structure is relatively simple, failing to fully meet the physiological needs of breeding geese, causing their reproductive performance to fall far short of its potential genetic level.

[0003] Existing technologies have significant limitations in addressing the aforementioned problems. For example, when using green fodder to reduce feed costs, its application is generally limited to extensive supplementation, lacking precise formulations based on the specific nutritional needs of breeding geese, thus failing to maximize its effectiveness. Furthermore, seasonal factors (especially winter) leading to interruptions in green fodder supply cause discontinuous nutrient intake for the flock, further hindering the stable improvement of breeding efficiency. Currently, technologies for using green fodder to reduce breeding costs while improving breeding efficiency are not uncommon. Therefore, how to provide a technology that utilizes green fodder to reduce breeding costs and improve breeding efficiency has become an urgent problem to be solved in this field. Summary of the Invention

[0004] To address the lack of an effective method in existing technologies for utilizing green fodder resources to improve breeding goose yields and reduce costs, this invention provides a breeding goose feed and its application, specifically including the following technical solution: This invention provides a breeding feed for geese, the breeding feed comprising goosegrass additive and complete feed; The mass ratio of the goosegrass additive to the complete feed is (0.02~1.8):0.4; The goosegrass additive includes fresh goosegrass or dried goosegrass.

[0007] The method for preparing the aquaculture feed as described above includes the following steps: mixing the goosegrass additive and the complete feed in a certain mass ratio to obtain the aquaculture feed; When the goosegrass additive is dried goosegrass, the processing method further includes: drying fresh goosegrass to a moisture content of ≤10%, crushing it, and passing it through a 40-80 mesh sieve to obtain dried goosegrass.

[0009] The present invention also provides the application of the breeding feed or the breeding feed prepared by the above-described method in the breeding of geese.

[0010] The present invention also provides a method for raising Zhejiang East White Goose breeding geese, using the breeding feed or the breeding feed prepared by the method described above to raise Zhejiang East White Goose breeding geese; The breeding methods include spring, summer and autumn breeding methods and / or winter breeding methods; The spring, summer and autumn breeding method includes the following steps: The Zhejiang East White Goose breeding geese were fed with aquaculture feed, with each goose receiving 1.0-1.8 catties of fresh goosegrass and 0.4 catties of complete feed per day; The winter breeding method includes the following steps: The Zhejiang East White Goose breeding geese were fed with aquaculture feed, with each goose receiving 0.02-0.15 catties of dried goose intestine grass and 0.36-0.48 catties of complete feed per day.

[0011] Preferably, the feeding times for fresh goosegrass, dried goosegrass, and complete feed are 8:00-10:00 AM daily.

[0012] Preferably, the breeding method further includes providing clean drinking water to the geese after they have free access to feed.

[0013] Preferably, the breeding method further includes the following steps: maintaining a male-to-female ratio of 1:5 for mixed breeding; and maintaining the temperature of the goose house at 5℃~30℃.

[0014] The beneficial effects of this invention are as follows: This invention belongs to the field of poultry farming technology and relates to a breeding feed for geese and its application. This invention provides a breeding feed for Zhejiang East White Geese, comprising a goosegrass additive and a complete feed; the mass ratio of the goosegrass additive to the complete feed is (0.02~1.8):0.4; the goosegrass additive includes fresh goosegrass or dried goosegrass. This invention utilizes wild goosegrass resources, reducing the consumption of complete feed by 20%. Goosegrass is rich in nutrients, and mixing it with complete feed can reduce the mortality rate by 58.3%, far exceeding industry expectations. Furthermore, mixing goosegrass with complete feed can increase the egg production of breeding geese, increasing annual income by 605,000 yuan per 10,000 breeding geese. Finally, goosegrass has vigorous reproductive capacity and wide distribution; therefore, the technical solution of this invention has universality and is applicable to all white goose farming areas in the Yangtze River basin. This invention provides a new approach to improving the economic benefits of breeding goose farming. Detailed Implementation

[0018] The present invention also provides a method for preparing the above-mentioned aquaculture feed, the steps of which include: mixing goosegrass additive and complete feed in a certain proportion to obtain the aquaculture feed.

[0019] As one implementation method, the ratio of the goosegrass additive to the complete feed is the same as described above, and will not be repeated here.

[0020] In one embodiment, when the *Gentiana macrophylla* additive is dried *Gentiana macrophylla*, the processing method further includes: cutting the freshly cut *Gentiana macrophylla* into 4-10cm sections, drying the fresh *Gentiana macrophylla* until the moisture content is ≤10%, pulverizing it, and passing it through a 40-80 mesh sieve to obtain dried *Gentiana macrophylla*. In another embodiment, when the *Gentiana macrophylla* additive is dried *Gentiana macrophylla*, the processing method further includes: cutting the freshly cut *Gentiana macrophylla* into 4cm sections, naturally sun-drying it until the moisture content is ≤10%, pulverizing it, and passing it through a 60 mesh sieve to obtain dried *Gentiana macrophylla*.

[0021] This invention also provides the application of the breeding feed or the breeding feed prepared by the method described above in the breeding of geese. As one embodiment, the breeding geese are preferably breeds raised in the Yangtze River White Goose breeding area. As another embodiment, the breeding goose breeds raised in the Yangtze River White Goose breeding area include the Zhejiang East White Goose.

[0022] The present invention also provides a method for raising Zhejiang East White Goose breeding geese, using the breeding feed or the breeding feed prepared by the method described above to raise Zhejiang East White Goose breeding geese; The breeding methods include spring, summer and autumn breeding methods or winter breeding methods; The spring, summer and autumn breeding method includes the following steps: feed the Zhejiang East White Goose breeding geese with breeding feed, and feed each goose 1.0-1.8 catties of fresh goose intestine grass and 0.4 catties of complete feed per day; The winter breeding method includes the following steps: feeding the Zhejiang East White Goose breeding geese with breeding feed, feeding each goose with 0.02~0.15 catties of dried goose intestine grass and 0.36~0.48 catties of complete feed per day.

[0023] As one implementation method, the ratio of the goosegrass additive to the complete feed is the same as described above, and will not be repeated here.

[0024] In one implementation, the feeding times for fresh chickweed, dried chickweed, and complete feed are from 8:00 AM to 10:00 AM daily. In another implementation, the feeding times for fresh chickweed, dried chickweed, and complete feed are any one of 8:00 AM, 9:00 AM, and 10:00 AM daily, or the midpoint between any two times. In a specific embodiment, the feeding times for fresh chickweed, dried chickweed, and complete feed are all from 9:00 AM daily.

[0025] In one implementation, the breeding method further includes providing clean drinking water to the geese after they have free access to feed. In another implementation, the breeding method further includes the following steps: maintaining a male-to-female ratio of 1:5 for mixed rearing; and maintaining a goose house temperature of 5℃ to 30℃. In one implementation, the temperature of the goose house must be ensured to not exceed 30℃ in summer and not fall below 5℃ in winter.

[0026] To further illustrate the present invention, the following detailed description, in conjunction with embodiments, of a breeding feed for geese provided by the present invention and its application, should not be construed as limiting the scope of protection of the present invention.

[0027] Experiment Example 1: Optimization Experiment of the Ratio of Goosegrass Additive and Complete Feed Three thousand 300-day-old Zhejiang White Geese of similar growth were randomly divided into six groups of 500 each. Five groups served as the experimental group, fed with fresh *Gnaphalium affine* at doses of 1.0, 1.2, 1.3, 1.5, and 1.8 jin / bird, respectively. In addition, all five groups received an extra 0.4 jin / bird of complete feed daily. The control group received only the complete feed at 0.5 jin / bird / day, without *Gnaphalium affine*. The complete feed was mixed with the fresh *Gnaphalium affine* and fed simultaneously. After 120 days of rearing from spring to early summer, physiological indicators of the different groups were recorded, and the results are shown in Table 1.

[0028] The complete feed was purchased from Zhejiang Tongyuan Feed Co., Ltd., and the product name is: compound feed for geese.

[0029] Table 1. Test results of indicators for different groups of breeding geese

[0030] As shown in Table 1, the egg production rate and crude protein utilization rate of Zhejiang East White Geese fed with 1.3 catties / bird fresh goosegrass + 0.4 catties of complete feed per day reached their peak. When the amount of fresh goosegrass fed exceeded 1.3 catties, the feed conversion rate decreased due to the excessive crude fiber content, and the increase in egg production also decreased accordingly.

[0031] Experiment Example 2: Screening of Process Parameters for the Preparation of Dried Goosegrass Material The same batch of chickweed harvested on the same day was cut into 3-5 cm sections, dried until the moisture content was ≤10%, pulverized, and then divided into 5 equal portions. These portions were sieved through 40 mesh, 60 mesh, 80 mesh, and 100 mesh to produce chickweed dry materials of different mesh sizes. The retention rates of key substances in the chickweed dry materials of different mesh sizes were determined using HPLC and other methods (with fresh grass as a 100% baseline). The results are shown in Table 2.

[0032] Table 2. Nutritional content of dried goosegrass feed with different mesh sizes.

[0033] As shown in Table 2, the retention level of nutrients in dried goosegrass feed is highest when the mesh size is 60 mesh.

[0034] 1200 Zhejiang white geese of similar growth were randomly divided into 4 groups of 300 each. During winter, they were fed different sizes of dried goosegrass feed (n=300 birds / group). Each goose was fed 0.3 catties of dried goosegrass feed and 0.4 catties of complete feed per day. The mortality rate of the white geese in the 60 mesh and 80 mesh goosegrass feed groups was calculated. The results are shown in Table 3.

[0035] Table 3. Mortality rates of Zhejiang White Geese fed with different mesh sizes of dried goosegrass feed.

[0036] As shown in Table 3, the failure rate of the 60-mesh group was 4.8% (significantly lower than the 6.1% of the 80-mesh group, p<0.01).

[0037] The results in Tables 2 and 3 show that the dried goosegrass obtained by passing it through a 60-mesh sieve can balance the retention rate of active ingredients (>85%) with processing efficiency, and reduce the mortality rate of Zhejiang white geese.

[0038] Example 1: Preparation method of dried goosegrass feed During the growing season of goosegrass, take the goosegrass harvested that day, wash it clean to remove impurities, cut it into 4cm sections, let it dry naturally until the moisture content is ≤10%, crush it, pass it through a 60-mesh sieve to obtain dried goosegrass material, and store it for later use.

[0039] Test Example 1: Core Component Detection Report of *Centella asiatica* Dried chickweed was prepared according to the method described in Example 1. The core components of both fresh and dried chickweed were analyzed using the following methods, and the results are shown in Table 4. The detection method is as follows: Moisture content: Refer to GB 5009.3 direct drying method; Crude protein: Refer to GB / T 6432 Kjeldahl method for nitrogen determination; Crude fiber: GB / T 6364-2006 Acid-base method; Total flavonoids: SN / T 4592-2016 Spectrophotometric method; Polyphenols: T / ZCSIA 8-2023 Spectrophotometric Method; β-glucan: NY / T 2006-2011 Enzymatic colorimetric method; Folic acid: NY / T 2895-2016 High performance liquid chromatography; Calcium and zinc: GB / T 13885-2017 Atomic absorption spectrometry.

[0040] Table 4. Results of component content determination in fresh *Gentiana macrophylla* grass

[0041] As shown in Table 4, Goosegrass is rich in nutrients, which is beneficial to improving the breeding effect of breeding geese when fed to them.

[0042] Test Example 2: Performance Inflection Point Test Referring to the components shown in Table 4, a synthetic feed simulating the active ingredients of *Centipeda minima* was prepared. The synthetic feed was prepared by mixing complete feed and dried *Centipeda minima* powder in a specific ratio to fix the crude protein content of the synthetic feed at 16.8%. Based on this, the mass percentage of flavonoid-polyphenol complex in the synthetic feed was gradually adjusted to 0.6%, 1.0%, 1.4%, and 1.8% dry matter, respectively. The synthetic feed was thoroughly mixed and fed to the animals. After 3 months of rearing, relevant indicators were sampled and measured. The results are shown in Table 5.

[0043] 0.6%: 90.5% complete compound feed, 9.5% dried goosegrass powder; 1.0%: 84% complete compound feed, 16% dried goosegrass powder; 1.4%: 78% complete compound feed, 22% dried goosegrass powder; 1.8%: 71.5% complete compound feed, 28.5% dried goosegrass powder; Table 5. Mortality rate and gonadotropin increase in Zhejiang East White Geese fed with different active ingredient contents.

[0044] As shown in Table 5, compared with the control group fed with complete feed in Example 1, the mortality rate of the control group was 10.25%, while the mortality rate in this test case was 4.7% when the active ingredient content was 1.4%, a reduction of 54.15%. Secondly, the group with an active ingredient content of 1.8% showed a 50.24% reduction in mortality rate compared to the control group. This indicates that an active ingredient content of 1.4-1.8% represents a rigid threshold for a ≥50% reduction in mortality rate. When the flavonoid-polyphenol content was ≥1.4%, the Salmonella inhibition rate (ELISA detection) also jumped to >75%, demonstrating that an active ingredient content of 1.4-1.8% can inhibit Salmonella, promote goose production, and reduce mortality rate.

[0045] Example 2: A feed for raising Zhejiang white geese The aquaculture feed includes spring, summer and autumn aquaculture feed and winter aquaculture feed; The spring, summer and autumn breeding feed includes: fresh goosegrass and complete feed; The mass ratio of fresh goosegrass to complete feed is 1.3:0.4; The winter feed for livestock includes: dried goosegrass feed and complete feed; The mass ratio of dried goosegrass feed to complete feed is 0.11:0.39; The dried goosegrass was prepared using the method described in Example 1.

[0046] Example 3: A High-Efficiency Breeding Method for Zhejiang White Geese The efficient aquaculture method uses the aquaculture feed described in Example 2 for feeding; Spring, summer and autumn breeding methods: Fresh goosegrass was mixed with complete feed in a certain proportion and fed to the geese at 9:00 am every day, allowing them to eat freely. The feeding ratio of fresh goosegrass to complete feed is 1.3 catties / bird: 0.4 catties / bird; Winter farming methods: The dried goosegrass feed prepared according to the method described in Example 1 was mixed with complete feed in a certain proportion and fed to the geese at 9:00 am every day, allowing them to eat freely. The feeding ratio of dried goosegrass to complete feed is 0.11 catties / bird : 0.39 catties / bird; The dried goosegrass was prepared according to the method described in Example 1.

[0047] Of the spring, summer, autumn, and winter breeding methods, the remaining breeding conditions are as follows: In the goose house, the ratio of male geese to female geese is maintained at 1:5 throughout the year; drinking water: clean drinking water is provided immediately after the geese have free access to feed throughout the year; The temperature in the goose house should not exceed 30℃ in summer and should not be lower than 5℃ in winter.

[0048] Example 4: Verification of the effect of feeding with dried goosegrass. Example group: Zhejiang white geese were raised using the method described in Example 3.

[0049] Comparative control group: The breeding method was the same as in Example 3, except that the birds were fed 0.5 catties / bird / day of complete feed throughout the year.

[0050] The indicators of the Zhejiang white geese in the comparative and example groups were statistically analyzed, and the results are shown in Table 6.

[0051] Table 6. Statistical results of indicators after feeding Zhejiang White Geese with dried goosegrass feed.

[0052] As can be seen from the results in Table 6, the breeding method described in Example 1 of this invention overcomes the problem of seasonal shortages of green fodder and lack of nutritional continuity compared to conventional green fodder breeding methods. Furthermore, compared to conventional feeding methods, the breeding method of this invention can increase the annual egg production of breeding geese and reduce the mortality rate and breeding costs.

[0053] Example 5: Comprehensive Benefit Boundary Verification Scenario Simulation: The price of complete feed fluctuates on average between 1.1 yuan / jin and 1.5 yuan / jin. The traditional feeding method for Zhejiang East White Geese is 0.5 jin / bird / day. In this invention, the feeding amount of complete feed is 0.39-0.4 jin / bird / day. The supply cost of goosegrass is 0.02 yuan / jin for fresh grass and 0.4 yuan / jin for dried goosegrass. Based on the above price range, the costs incurred in goosegrass farming are calculated, and the results are shown in Table 7.

[0054] Table 7. Costs of raising Zhejiang East White Geese

[0055] As shown in Table 7, even with fluctuations in the price of complete feed, the feed cost of this invention can be stably reduced by 12.7% to 19%, which can significantly reduce breeding costs.

[0056] Implementation benefits (based on a breeding farm of 10,000 geese): Original feed cost = 10,000 birds × 0.5 catties × 1.3 yuan / catties × 365 days = 2,372,500 yuan; Feed cost of this invention: Spring, Summer and Autumn: 10,000 birds × (0.4 jin × 1.3 yuan / jin + 1.3 jin × 0.02 yuan / jin) × 274 days = 1,496,040 yuan; Winter: 10,000 birds × (0.39 jin × 1.3 yuan / jin + 0.11 jin × 0.4 yuan / jin) × 91 days = 501,410 yuan; Actual savings = 375,050 yuan.

[0057] Value-added benefits: Increased egg production = 10,000 birds × (30~28) = 20,000 birds (valued at 2 yuan / bird, worth 200,000 yuan). Increased value of surviving breeding geese = 10,000 birds × 7% mortality rate × 300 yuan / bird (estimated) = 210,000 yuan The overall benefits increased by 605,000 yuan per 10,000 birds per year.

[0058] The results of the above test and experimental examples show that *Centella asiatica* is rich in flavonoids and polyphenols. The synergistic effect of flavonoids and polyphenols can increase the secretion of gonadotropins in breeding geese by 22.3%. It also has a high β-glucan content, which can stimulate macrophage activity in breeding geese, reduce mortality, and inhibit intestinal pathogens (such as Salmonella) by more than 75%. Compared with the control group, the mortality rate of the group fed *Centella asiatica* was reduced by 58.3%.

[0059] In summary, this invention provides a method for feeding Zhejiang White Geese by mixing fresh or dried Goosegrass with complete feed. This method effectively utilizes green fodder resources to reduce the breeding cost of geese. Furthermore, this invention limits the use of dried Goosegrass with complete feed during winter, ensuring the continuity of green fodder nutrition. The nutrients in the Goosegrass feed can also improve the resistance of breeding geese, reduce mortality, and increase egg production. Therefore, the Goosegrass additive of this invention and its application provide a more economical and effective solution for the large-scale breeding of Zhejiang White Geese.

[0060] Although the above embodiments have provided a detailed description of the present invention, they are only some embodiments of the present invention, not all embodiments. People can obtain other embodiments without creative effort, as shown in these embodiments, and these embodiments all fall within the protection scope of the present invention.
