Description

Technical Field

[0001] This invention belongs to the field of animal husbandry technology, and in particular relates to an ecologically healthy method for breeding superior cattle breeds. Background Technology

[0002] In the current field of cattle breeding, conventional technical systems mainly revolve around core aspects such as genetic breeding, artificial insemination, nutritional support, and disease prevention. Existing technologies generally rely on genetic evaluation and selection based on pedigree records of bulls and cows, production performance data (such as milk yield and daily weight gain), and conformation, aiming to transfer superior genes. During the breeding process, artificial insemination technology has been widely used, using semen from superior bulls to improve the genetic level of offspring. In feeding management, emphasis is placed on formulating complete diets according to the different physiological stages of cattle to meet their nutritional needs. Disease control focuses on programmed vaccination of the herd and treatment-based strategies for common calf diseases (such as diarrhea and pneumonia). In addition, some modern ranches use boilers, fans, and other equipment to regulate the temperature and ventilation of livestock sheds to improve feeding conditions.

[0003] While existing technologies provide a foundation for the propagation of superior breeds, they still suffer from systemic shortcomings. First, parental selection often focuses on genetic and phenotypic data, neglecting the social behavioral structure and individual adaptability within the herd. This can lead to chronic stress in selected "superior" breeding stock in high-density group settings, which is detrimental to the stable expression of reproductive performance. Second, environmental control often emphasizes the static maintenance of physical factors such as temperature and humidity, lacking the programmed application of light as a key circadian rhythm regulator, and failing to achieve dynamic synergistic regulation of light and temperature. Therefore, it is difficult to proactively and efficiently induce and synchronize the natural estrus cycle of the herd, hindering the efficiency of large-scale, batch-based breeding management. Third, the health protection model for calves is relatively passive, mainly relying on postnatal vaccination and post-illness drug treatment, failing to fully utilize the window of opportunity during the cow's gestation period to proactively enhance the calf's innate immunity through nutritional and immune interventions. This results in high morbidity rates during lactation and severe antibiotic dependence. Finally, the existing technologies are relatively isolated in each stage, failing to form a comprehensive ecological health management plan that integrates parental selection, physiological regulation and offspring health protection, and also lacks consideration for resource recycling and animal welfare. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an ecological and healthy method for breeding superior cattle breeds, which solves the problems of neglecting parental behavioral adaptation, extensive environmental control, passive offspring health protection, and insufficient coordination among various links in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An ecologically healthy method for breeding superior cattle includes the following steps:

[0007] S1. Selection of breeding parents: Conduct behavioral observations on the superior cattle population and classify them into grades based on their social behavior; use pedigree analysis to select individuals of the same grade with low kinship coefficients as breeding parents;

[0008] S2. Group rearing and stress control: The selected breeding parents were reared in groups, with the dominant individuals fed a low-nitrogen, high-fiber diet and the subordinate individuals given separate feeding areas; the stress hormone cortisol levels of the breeding parents were monitored in real time and controlled.

[0009] S3. Environmental control and estrus synchronization: Construct a manure fermentation heat recovery system to heat the feeding shed, set up an intelligent photoperiod control device and set the light parameters according to the latitude of the native habitat of the superior cattle, establish a linkage control method for temperature and light, and realize the synchronization of estrus of the breeding parents.

[0010] S4. Pre-breeding forage induction: 30 days before estrus in cows and 45 days before semen collection in bulls, differentiated forage combinations are prepared and fed according to the intended use of the breed of cattle, and secondary metabolites of the forage are used to induce and enhance reproductive function.

[0011] S5. Motion monitoring and early warning: Equip all breeding parents with collar-type accelerometers, set differentiated motion parameters according to breed and physiological stage, and establish a motion parameter early warning method;

[0012] S6. Maternal Immunization and Antibody Transmission: During the mid-pregnancy period of high-quality cows, natural immune enhancers are added to their diets; at the same time, inactivated antigens of pathogens that are easily infected by calves during lactation are prepared and administered to pregnant cows via sublingual immunization, so that antibodies are transmitted to calves through the placenta and colostrum.

[0013] Preferably, in step S1, the behavioral observation is conducted for 15 consecutive days, with each day's observation time not less than 8 hours; the ranking is divided into dominant individuals, intermediate individuals, and subordinate individuals based on feeding priority, territorial fighting frequency, and group following behavior; the screening refers to screening individuals of the same ranking with a kinship coefficient of <5%.

[0014] Preferably, in step S2, the low-nitrogen, high-fiber diet consists of straw and bran in a weight ratio of 8:2; the standard for setting up the independent feeding area is no less than 2 square meters per cow; the regulation refers to adjusting the cortisol level to 10-15 ng / mL.

[0015] Preferably, in step S3, the heating controls the temperature of the breeding shed at 18-22℃; the setting standard for the light parameters is: when the latitude of the native habitat is not less than 35 degrees, a cycle of 14 hours of light and 10 hours of darkness per day is adopted; when it is less than 35 degrees, a cycle of 12 hours of light and 12 hours of darkness per day is adopted; the linkage control method is to automatically extend the light duration by 0.5-1 hour when the temperature of the breeding shed is lower than 18℃.

[0016] Preferably, in step S4, the differentiated forage combination configuration standard is as follows: dairy cattle are fed a mixture of alfalfa and yellow oxalis forage in a ratio of 7:3; beef cattle are fed a mixture of sheepgrass and alfalfa forage in a ratio of 6:4.

[0017] Preferably, in step S4, the amount of forage fed is 2.5% of the body weight of each breeding parent per day.

[0018] Preferably, in step S5, the differentiated exercise parameters are set as follows: young bulls exercise at a constant speed of 2.5 kilometers per hour for 30 minutes twice a day; and pregnant cows exercise freely for 20 minutes once a day during late pregnancy.

[0019] Preferably, in step S5, the early warning method is: when the sensor monitoring data deviates from the set value by ±10%, a control reminder is triggered.

[0020] Preferably, in step S6, the second trimester is from day 120 to day 180 of pregnancy; the natural immune enhancer is a compound preparation of astragalus polysaccharide, propolis extract and yeast cell wall polysaccharide, and the amount added is 0.2% of the daily diet weight.

[0021] Preferably, in step S6, the pathogens that calves are susceptible to during lactation are bovine mycoplasma and rotavirus.

[0022] The technical effects and advantages of the ecological and healthy method for breeding superior cattle according to the present invention are as follows:

[0023] 1. This invention integrates behavioral observation and pedigree analysis to screen parents, ensuring the quality and stability of the breeding population. Furthermore, through a unique manure fermentation heating and intelligent light-temperature linkage environmental control system, it can accurately and efficiently induce and achieve a high degree of synchronization of the estrus cycle in the cattle herd. This allows subsequent management work such as artificial insemination and pregnancy diagnosis to be carried out in a centralized and batch manner, significantly reducing the manpower and time costs of estrus detection, and greatly improving the conception rate during estrus and the overall efficiency of the breeding plan.

[0024] 2. This invention innovatively implements nutritional fortification and targeted sublingual immunization during the critical period of cow pregnancy, enabling the generated specific antibodies to be efficiently delivered to calves via both the placenta and colostrum. This provides calves with strong passive immune protection against specific pathogens (such as bovine mycoplasma and rotavirus) from birth, significantly reducing the incidence and severity of common diseases such as diarrhea and respiratory infections during the most vulnerable lactation period. This fundamentally reduces reliance on preventative and therapeutic antibiotics, improving calf survival rates and overall herd health.

[0025] 3. This invention encompasses meticulous individual management of parent stock. Group rearing and stress control based on social hierarchy effectively reduce intragroup fighting and chronic stress, ensuring the welfare and feeding opportunities of individuals at all levels (especially subordinate individuals). Specific forage induction during the pre-breeding period utilizes plant-based active substances to positively regulate reproductive endocrine function. Combined with continuous exercise monitoring and early warning management, this ensures that parent stock maintains optimal body condition and physiological vitality throughout the entire breeding cycle. These measures work synergistically to create optimal physiological and psychological conditions for maximizing reproductive performance.

[0026] 4. This invention practices the concept of circular agriculture, converting livestock manure into clean heat energy, reducing the consumption of external energy and carbon emissions. Through the aforementioned health management measures, especially the significant reduction in calf morbidity and medication dosage, production costs and the risk of veterinary drug residues are directly reduced, improving the safety, quality, and market competitiveness of livestock products. Increased reproductive efficiency and survival rates directly increase output and profits. Therefore, this invention improves the core production indicators of livestock farms while promoting the ecological sustainability of the production system, achieving a win-win situation for both economic and environmental benefits.

[0031] Example 1

[0032] This embodiment provides an ecologically healthy method for breeding superior cattle breeds, used for basic process implementation, and the specific implementation content includes:

[0033] This embodiment demonstrates the specific implementation of the six basic steps of the method described in claim 1.

[0034] Purpose of implementation: To verify the feasibility and basic effectiveness of the core processes “S1 to S6”.

[0035] Implementation steps:

[0036] S1. Selection of Breeding Parents: 120 healthy Holstein heifers were selected and their behavior was observed for 15 consecutive days, 8 hours a day. Based on feeding, fighting, and following behaviors, they were divided into three levels: dominant (15), intermediate (85), and subordinate (20). Combined with pedigree analysis, 5 heifers of the dominant level with a kinship coefficient of <5% were selected, along with 3 bulls that met the same criteria.

[0037] S2. Group rearing and stress control: Eight dominant broodstock cattle were raised together and fed a low-nitrogen, high-fiber diet composed of corn stalks and wheat bran in an 8:2 ratio. A separate control group of five dependent cattle was established, with independent feeding areas (≥2㎡ per head). Serum cortisol levels were monitored weekly and controlled to 12-14 ng / mL using environmental enrichment measures.

[0038] S3. Environmental Control and Estrus Synchronization: Manure fermentation produces biogas to heat the cattle shed's floor heating system, maintaining a stable temperature of 20±1℃. A 14-hour light / 10-hour dark light cycle is set, and the system is programmed to automatically extend the light exposure by 0.5 hours when the temperature drops below 18℃. After 28 days of operation, all 7 parent cattle exhibited estrus within 5 days, achieving a synchronization rate of 87.5%.

[0039] S4. Forage induction in the early breeding stage: 30 days (cows) and 45 days (bulls) before the start of S3, feed a mixture of alfalfa and yellow oxalis in a 7:3 ratio, with a daily feed amount of 2.5% of body weight.

[0040] S5. Motion Monitoring and Early Warning: All parent cattle are equipped with accelerometers. Young bulls are required to complete two 30-minute exercise sessions daily at a speed of 2.5 km / h; cows are required to complete 20 minutes of free exercise. An early warning is triggered if the data deviates from the set values ​​by ±10%.

[0041] S6. Maternal Immunity and Antibody Transmission: For pregnant cows, starting from day 150 of gestation, 0.2% of a compound immune enhancer (such as astragalus polysaccharide) was added to the diet, and bovine mycoplasma and rotavirus sublingual inactivated vaccines were administered simultaneously. Postpartum testing showed that the colostrum antibody titer was 6-8 times higher than the control group, and the serum antibody positivity rate of the calves reached 100%.

[0042] Implementation results: Preliminary verification shows that the core process can achieve estrus synchronization and enable calves to acquire a high level of specific passive immunity through maternal immunization.

[0043] Example 2

[0044] This embodiment provides an ecologically healthy method for breeding superior cattle breeds, focusing on the synergistic effects of stress regulation and herd management. Specific implementation details include:

[0045] Objective: To explore the synergistic effect of refined implementation of step S2 on improving overall reproductive performance.

[0046] Implementation steps: After identifying Simmental cattle broodstock in S1, intensify S2 management: Separate dominant individuals (Group A) from subordinate individuals (Group B). Group A is fed a specific diet, while Group B is provided with welfare facilities (such as a brush) in addition to its independent feeding area. Precisely control cortisol levels in both groups to 10-12 ng / mL. Subsequent steps S3 to S6 are implemented according to standard procedures.

[0047] Results: The estrus onset time of cattle in groups A and B was on average 7 days earlier than that of the mixed-species control group, and the early embryo loss rate was reduced by approximately 38%. This demonstrates that refined S2 management can effectively reduce stress and significantly optimize reproductive performance.

[0048] Example 3

[0049] This embodiment provides an ecologically healthy method for breeding superior cattle breeds, and a forage induction program for cattle for different purposes. Specific implementation details include:

[0050] Objective: To compare and verify the effectiveness of different forage induction programs for dairy and beef cattle in step S4.

[0051] Implementation steps: Holstein (dairy) and Angus (beef) heifers were selected and divided into experimental and control groups after S1 screening. The experimental group underwent S4 induction: Holstein cattle were fed a 7:3 ratio of alfalfa to yellow clover; Angus cattle were fed a 6:4 ratio of sheepgrass to alfalfa, with each group receiving 2.5% of their body weight. The control group was fed ordinary hay. Subsequently, S3 synchronization and mating were performed.

[0052] Results: The conception rate during estrus was 85% in the Holstein experimental group (compared to 72% in the control group), and 88% in the Angus experimental group (compared to 79% in the control group). The experimental group cows showed better synchronicity in follicle development, confirming that targeted forage induction can effectively improve reproductive function.

[0053] Example 4

[0054] This embodiment provides an ecologically healthy method for breeding superior cattle breeds, which is used for the application of exercise monitoring in long-term reproductive management. Specific implementation details include:

[0055] Purpose of implementation: To demonstrate the continuous management value and early warning capabilities of the S5 steps throughout the entire reproductive cycle.

[0056] Implementation steps: Implement S5 exercise monitoring long-term in a breeding herd. Establish differentiated daily exercise parameters (such as duration and intensity) for bulls, non-pregnant cows, and late-pregnancy cows, and set warning thresholds of ±15%. Continuously monitor and respond to warnings over a 10-month management cycle.

[0057] Implementation Results: The system successfully issued warnings for insufficient exercise and abnormal individual activity 27 times, helping managers to detect and treat 3 cases of hoof inflammation at an early stage. The herd condition score of cattle remained stable within the ideal range, the incidence of limb and hoof diseases decreased by 40%, and the exercise data also provided a reference for estrus identification.

[0058] Example 5

[0059] This embodiment provides an eco-friendly and healthy method for breeding superior cattle breeds, used for integrated, end-to-end commercial demonstration. Specific implementation details include:

[0060] Purpose of implementation: To comprehensively demonstrate the integrated application effect of all features of claims 1-10 in a commercial ranch.

[0061] Implementation steps: In a demonstration herd of 100 dairy cows, implement the entire process from S1 to S6 completely and to a high standard:

[0062] S1: 45 low-kinship cows and 8 bulls were rigorously selected.

[0063] S2: Group by grade and adjust cortisol to approximately 13 ng / mL.

[0064] S3: Utilize a combined heat and power system for manure and sewage to control the temperature (20℃) and implement intelligent light and temperature linkage (14L:10D).

[0065] S4: Feed a uniform 7:3 ratio of alfalfa and yellow spiny bean grass for 45 days before mating.

[0066] S5: All staff wear motion monitoring collars, with 100% response and alerts.

[0067] S6: Add 0.2% immune enhancer during the second trimester and complete sublingual immunization.

[0068] Results: The estrus synchronization rate in the demonstration group was 92%, and the first conception rate was 80%. The incidence of diarrhea during lactation in the calves was only 6.5%, far lower than the 31% in the control group. Antibiotic use in calves was reduced by more than 70%, and the weaning survival rate reached 99%.

[0069] Comparative Example 1

[0070] This comparison provides traditional breeding management methods, including:

[0071] Purpose of implementation: To use conventional methods for management as a benchmark to highlight the advantages of this invention.

[0072] Implementation steps: Select cattle from the same herd, choosing breeds solely based on milk production and body size; large-scale mixed rearing without grouping or stress control; conventional boiler heating with no photoperiod management; no pre-breeding forage induction; reliance on artificial observation of estrus with no exercise monitoring; no special immunization intervention during pregnancy, with calves relying on post-birth vaccination.

[0073] Results: Estrus in the cattle herd was dispersed, and the conception rate during estrus was 66%. The incidence of diarrhea in lactating calves reached 34% (of which 15% required antibiotic treatment), and the weaning survival rate was 92%. It was significantly inferior to the integrated solution of this invention in terms of reproductive efficiency, calf health, and medication costs.

[0074] Compared to Examples 1-5 and Comparative Example 1, Examples 1-5 of this invention and the comparative example reveal a systematic divergence between two drastically different reproductive management paradigms in terms of philosophical foundation, technological logic, and ultimate effectiveness. The traditional model represented by the comparative example is based on experiential learning, passive response, and the stacking of elements. It relies on isolated breeding indicators (such as milk yield or body size) while ignoring the behavioral adaptability of individuals in real communities; it provides basic food and shelter but lacks the programmed application of photoperiod, a core biological rhythm regulator, and is unable to achieve intelligent synergy among environmental factors to proactively guide physiological processes; its health management begins after calf birth, relying on programmed vaccination and a passive cycle of "treatment-medication." This technological path is essentially discrete, responsive, and remedial, with each link (breeding, nutrition, environment, veterinary medicine) isolated from each other, preventing the flow of information and benefits, resulting in high management costs and significant efficiency bottlenecks. In contrast, the system constructed by the embodiments of this invention is based on a holistic view, proactive intervention, and ecological synergy. Starting with S1 (behavioral-genetic co-screening), the focus is on building a parent population with both excellent genetic potential and high social adaptability, laying a stable biological foundation for all subsequent interventions. S2 (grouping and precise stress regulation) is not simply physical isolation, but rather a deep understanding and proactive management of community structure based on animal behavior. Through differentiated nutrition and facility support, the physiological stress level of the population is regulated to the optimal window, a necessary prerequisite for releasing reproductive potential. S3 (intelligent light and temperature linkage regulation) breaks away from the constraints of static environmental control, achieving ecological cycling through the energy utilization of manure, and innovatively coupling the light cycle with temperature dynamics to simulate and optimize key natural signals driving the estrus cycle, thereby achieving the "programming" and synchronization of the herd's reproductive rhythm. This is a core leap from "relying on nature" to "planned production" in reproductive management. S4 (nutritional induction) and S5 (movement monitoring) This is a refined "adjustment" based on the previous approach. The former utilizes specific plant secondary metabolites to positively regulate reproductive endocrine function during critical window periods, while the latter uses digital means to ensure that individuals maintain optimal physical condition and vitality throughout the reproductive cycle. Together, they ensure that the reproductive machinery operates at its best. Ultimately, S6 (maternal active immunization) completes a fundamental transformation in health management from "treating existing diseases" to "preventing diseases." Through nutritional fortification and mucosal immunity administered by the mother during fetal development, high levels of specific protective immunity are "written" into the offspring's life starting point, constructing a powerful innate immune defense line. These six steps are not simply a linear superposition, but rather constitute an organic whole with an efficient cycle of information flow, material flow, and energy flow. Each step creates more optimized conditions for the next, ultimately converging into a powerful synergistic effect.

[0075] This fundamental difference in pathways directly translates into a massive, quantifiable, and verifiable gap in benefits. In terms of reproductive efficiency, under the traditional model (comparative example), estrus in cattle is sporadic and scattered, with a conception rate during estrus remaining at approximately 66%, a prolonged calving season, and dispersed management efforts. However, in the herd applying the entire process of this invention (as in Example 5), the estrus synchronization rate exceeds 90%, and the first-time conception rate increases to approximately 80%, achieving highly intensive batch production and significantly reducing unit reproductive costs. The difference is even more striking in terms of calf health and survival: in the comparative example, calves face a diarrhea incidence rate as high as approximately 34% during lactation, nearly half of which require antibiotic intervention, and the weaning survival rate is only 92%; while this invention, through intervention in step S6, provides calves with strong maternal antibody protection, suppressing the diarrhea incidence rate during the same period to an extremely low level of approximately 6.5%, drastically reducing antibiotic use by over 70%, and increasing the weaning survival rate to over 99%. This not only signifies huge savings in veterinary drug costs but also represents a substantial improvement in animal welfare and a significant reduction in food safety risks. In terms of the combined economic and ecological benefits, the advantages of this invention are comprehensive: the energy conversion of manure (S3) reduces dependence on external fossil fuels and achieves on-farm material recycling; precise health management greatly reduces the environmental pressure of drug residues and emissions; and the dual improvement in reproductive efficiency and survival rate directly increases the quantity and quality of healthy calves available for sale. Therefore, the value of this invention goes far beyond the improvement of a single technical indicator. Rather, it represents the optimization of the entire chain from resource input and process control to healthy output through a precisely designed and interconnected system engineering approach. This represents the inevitable path for the transformation and upgrading of the breeding industry towards high efficiency, greenness, sustainability, and animal welfare friendliness. The comparison between the examples and comparative examples ultimately proves a core argument: in complex livestock production systems, solving deep-seated problems cannot rely on the simple accumulation of technical points, but must rely on a systematic solution based on a profound biological understanding and with deep synergy among all links.
