Description

Technical Field

[0001] The invention relates to the technical field of animal breeding, in particular to an ecological breeding method for sika deer. Background Art

[0002] The traditional sika deer breeding method has obvious defects in many aspects, which limits the improvement of breeding and ecological benefits. First of all, the traditional breeding method lacks scientific planning in site layout, and often fails to make reasonable zoning according to the living habits and ecological needs of sika deer, resulting in poor breeding environment and low quality of life for sika deer.

[0003] Secondly, in terms of breed selection and introduction, traditional methods often lack strict screening standards and comprehensive health checks, resulting in uneven quality of introduced sika deer and increasing the risk of disease transmission. In addition, traditional breeding is not sophisticated enough in feed management, the feed formula is single, and there is a lack of personalized management for different growth stages and gender differences, resulting in unbalanced nutritional intake of sika deer, affecting their healthy growth. In terms of health monitoring and disease prevention and control, traditional methods lack high-precision, real-time monitoring equipment and means, and are unable to promptly detect and deal with sika deer health problems. Disease prevention and control measures are also relatively lagging, which can easily cause the spread of the epidemic. At the same time, traditional breeding does not pay enough attention to the creation of an ecological environment, lacks the introduction of multi-level vegetation and ecological factors such as insects and birds, resulting in a monotonous breeding environment and an incomplete ecological chain, which is not conducive to the healthy growth of sika deer.

[0004] Finally, in terms of breeding management, traditional methods lack systematicity and scientificity, breeding plans are unreasonable, and reproductive health examinations are not comprehensive, resulting in low population quality and low breeding efficiency.

[0005] In summary, the traditional sika deer breeding method has obvious defects in many aspects, and a new and scientific breeding method is needed to overcome these shortcomings and improve breeding and ecological benefits. Summary of the invention

These measures comprehensively improve the breeding efficiency, ecological benefit and social benefit, bring a new sustainable, efficient and healthy model to sika deer breeding, and greatly promote the development of the industry.

[0008] Technical Solution

[0009] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0010] An ecological breeding method for sika deer, the method comprising the following steps:

[0011] Site layout and construction: Select an area of ​​no less than 10,000 square meters with natural water sources and undulating terrain to build a breeding site, and divide the site into living and breeding areas, sports and leisure areas, feed planting areas, and isolation and quarantine areas;

[0012] Selection and introduction of sika deer: The selection is based on the age, weight and physical appearance of sika deer. The age of sika deer is limited to 1.5 to 4.5 years old, and the weight range is 40 kg to 90 kg. The physical appearance requires a symmetrical body, no obvious deformities in the limbs, intact fur, clear eyes, and complete teeth. Before introduction, a comprehensive health check is conducted on the sika deer. The inspection items include but are not limited to routine blood tests, parasite tests and infectious disease screening. Routine blood test indicators include the number of red blood cells, white blood cells and platelets. Parasite detection uses a combination of fecal sampling and serum testing. Infectious disease screening targets deer pox, deer pasteurellosis and deer brucellosis. The introduction process uses specially designed transport vehicles, and the transportation time is controlled within 8 hours. After arriving at the breeding site, they directly enter the isolation and quarantine area for a 45-day isolation observation. During the isolation period, a health check is conducted every 5 days, and the inspection items are the same as before introduction.

[0013] Feed supply and management: Feed formulas are formulated according to the different growth stages, seasonal changes and gender differences of sika deer. Feed processing adopts a mechanized processing line.

[0016] Waste treatment and recycling: A waste collection system is built in the living and breeding area, including feces collection pipes and urine collection pools. The feces collected by the feces collection pipes enter the fermentation pool for fermentation treatment. The fermented feces are made into organic fertilizer and used for fertilizing the vegetation around the feed planting area and the breeding site. The urine collection pool collects and dilutes the urine, and then uses it for grassland irrigation through the irrigation system.

[0017] Reproduction management and population optimization: Establish a breeding file for sika deer to record the birth information, parent information, breeding history and health status of sika deer; arrange breeding plans according to the reproductive physiological characteristics and seasonal changes of sika deer, and adopt a breeding method that combines natural mating with artificial insemination; provide comprehensive care for newborn fawns, and the lactation period of fawns is 3.2 to 3.8 months. During the lactation period, solid feed is gradually added for supplementary feeding according to the growth of the fawns. After the fawns are 6.2 months old, they are weaned and raised in groups based on the sex, weight and health status of the fawns; in terms of population optimization, conduct genetic evaluations of the sika deer population on a regular basis, eliminate poor individuals based on the evaluation results, retain good individuals as breeding deer, and gradually improve the overall quality and adaptability of the sika deer population.

The electric energy storage and conversion device of the living house has an intelligent charging and discharging management function, which can automatically adjust the charging and discharging mode according to the power of the electrical equipment in the house and the power generation power of the solar panel, thereby improving the efficiency of electric energy utilization.

[0019] Furthermore, the transport vehicles used in the selection and introduction of sika deer have a closed structure with an adjustable partition device inside the compartment. The partition device is made of a composite material of plastic and metal and has a height of 1.2 meters. The bottom of the compartment is paved with shock-absorbing and anti-skid padding with a thickness of 8 centimeters. The padding is a mixture of rubber and fiber materials. The compartment is equipped with ventilation and adjustment equipment, temperature control equipment, humidity control equipment, and real-time monitoring and data transmission equipment. The air volume adjustment range of the ventilation and adjustment equipment is 12 cubic meters to 18 cubic meters per hour, and the temperature control equipment can adjust the air volume to 12 cubic meters per hour. The temperature in the car is controlled at 8°C to 22°C, and the humidity regulating device can control the humidity in the car at 45% to 65%; the connection part of the partition device adopts a sealing structure, and the sealing material is rubber. The sealing performance can ensure the stability of the air pressure in the car and reduce the risk of invasion of external pathogens. The vehicle's shock-absorbing and anti-slip padding has a self-cleaning function, which can remove surface dirt through water washing to keep the padding clean and hygienic. The vehicle's temperature control equipment adopts a dual-temperature zone control mode, and different temperature zones can be set according to the distribution of sika deer in different areas of the car to improve the transportation comfort of sika deer.

[0020] Furthermore, in the processing line of feed supply and management, the raw materials are first crushed to a particle size of 1.5 mm to 2.5 mm, and then mixed and stirred for 12 minutes. Finally, they are made into granular or block feed according to the feeding habits of sika deer. The diameter of the granular feed is 1 cm to 1.3 cm, and the side length of the block feed is 2.2 cm to 2.8 cm. The crushing device adopts a multi-stage crushing structure, which can crush the feed raw materials to a particle size of 0.2 mm to 0.8 mm, thereby improving the crushing effect of the feed raw materials. The mixing and stirring device adopts vacuum stirring technology, which can effectively remove bubbles generated during the stirring process, improve the mixing uniformity of the feed, and make the distribution of feed nutrients more even.

[0021] Furthermore, in health monitoring and epidemic prevention and control, the environmental monitoring system includes temperature sensors, humidity sensors, ammonia sensors and light sensors. The temperature sensor has a measurement accuracy of ±0.3°C, the humidity sensor has a measurement accuracy of ±2%, the ammonia sensor has a measurement accuracy of ±0.8ppm, and the light sensor has a measurement accuracy of ±8lux. The sensor transmits the collected environmental data to the data processing center, which makes early warning judgments based on preset thresholds.

[0022] The sika deer health monitoring system includes but is not limited to a contactless weight measuring instrument, a body temperature measuring instrument, a heart rate measuring instrument and a behavior monitoring camera. The measurement accuracy of the contactless weight measuring instrument is ±0.3 kg, the measurement accuracy of the body temperature measuring instrument is ±0.15°C, and the measurement accuracy of the heart rate measuring instrument is ±3 times / minute. The behavior monitoring camera monitors the behavior status of the sika deer in eating, drinking, exercising and resting. The monitoring data is transmitted to the data processing center, and the data processing center analyzes and judges based on the normal physiological indicators and behavior patterns of the sika deer.

[0023] The data processing center adopts a distributed computing architecture, and the data processing speed is 30% to 50% higher than that of traditional data processing centers. It can analyze and process environmental data more quickly and issue early warnings. The behavior monitoring camera in the sika deer health monitoring system adopts a panoramic high-definition camera with a monitoring viewing angle range of 180 degrees to 360 degrees, which can fully cover the sika deer activity area and improve the accuracy of behavior monitoring.

[0024] Furthermore, in the creation and maintenance of the ecological environment, a variety of plants, including trees, shrubs and herbaceous plants, are planted around the breeding grounds and in the sports and leisure areas. The trees include poplars, willows and pine trees, the shrubs include forsythia, wolfberry and Amorpha fruticosa, and the herbaceous plants include dandelions, plantains and foxtails;

[0025] In the sports and leisure area, an insect breeding area and a bird habitat area are set up. The insect breeding area breeds earthworms, locusts and crickets in a mode combining artificial breeding boxes with natural grazing. The breeding boxes are made of wood or plastic, with a size of 60 cm × 60 cm × 40 cm to 90 cm × 90 cm × 60 cm. The breeding boxes are set up with environmental conditions suitable for insect growth, that is, the temperature is between 22℃ and 28℃, the humidity is between 52% and 68%, and the substrate is a mixture of soil and leaf mold in a specific proportion. The area of ​​the natural grazing area is 120 square meters to 180 square meters. Tall trees are planted in the bird habitat area and bird nests are set up to attract sparrows, magpies and woodpeckers to roost.

[0026] An intelligent light adjustment device is arranged in the breeding box in the insect breeding area, and the light intensity and the light duration can be adjusted according to the growth needs of the insects. The light intensity adjustment range is 500 lux to 5000 lux, and the light duration adjustment range is 8 hours to 16 hours, which improves the insect breeding efficiency. The insect hatching rate is increased by 20% to 30% compared with ordinary breeding boxes. In addition, a sound attraction device is arranged in the bird habitat area, which can play a variety of bird calls to attract more birds to inhabit. The bird stay time is extended by 2 hours to 4 hours compared with the case where the sound attraction device is not arranged.

[0027] Furthermore, in waste treatment and recycling, the feces collection pipe is made of corrosion-resistant plastic material with a diameter of 15 cm and a pipe laying slope of 4%. The collected feces enter the fermentation tank for fermentation treatment. The fermentation tank adopts a brick-concrete structure with a volume of 80 cubic meters. Microbial fermentation agents are added during the fermentation process. The fermentation time is 2 months and the fermentation temperature is controlled at 55°C to 65°C. The fermented feces are made into organic fertilizer.

[0028] The microbial fermentation agent adopts a high-efficiency composite bacterial agent, which is composed of a variety of highly active microorganisms. It can shorten the feces fermentation time by 12 to 18 days, and the main nutrient content of nitrogen, phosphorus and potassium in the fermented organic fertilizer is increased by 18% to 28% compared with the ordinary fermentation method, which is more conducive to plant growth.

[0029] Furthermore, in breeding management and population optimization, the breeding plan is arranged according to the reproductive physiological characteristics and seasonal changes of sika deer. The breeding season of sika deer is from October to December every year. Before breeding, the male and female deer are examined for reproductive health. The examination items include semen quality examination, ovarian function examination and sex hormone level detection. The semen quality examination indicators are sperm motility, sperm density and sperm deformity rate. The ovarian function examination adopts the combination of ultrasound examination and blood hormone detection. The sex hormone level detection includes testosterone, estradiol and progesterone hormone level detection. Only reproductively healthy male and female deer are selected for breeding.

[0030] The breeding method is a combination of natural mating and artificial insemination. The ratio of male to female deer in natural mating is 1:5. During artificial insemination, the semen of the male deer is collected first. The semen is collected by electrical stimulation or pseudo-vagina method. The collected semen is tested and processed for quality. The quality test indicators are sperm motility, sperm density and sperm deformity rate. The processing includes semen dilution and cryopreservation. The frozen semen is thawed and revived before use. The semen motility after thawing and resuscitation is between 0.55 and 0.65. The insemination process adopts the rectal grasping insemination method to inject semen into the uterus of the doe. After insemination, the pregnancy diagnosis of the doe is carried out. The pregnancy diagnosis adopts the combination of ultrasound diagnosis and blood hormone detection. The ultrasound diagnosis is carried out 32 to 38 days after mating, and the blood hormone detection is carried out 22 to 28 days after mating. Special care is given to pregnant does, and a separate feeding environment is provided. The nutrient content of the feed is increased, and the protein content is between 19% and 21%, and the calcium-phosphorus ratio is 3.2:1.

[0031] The artificial insemination semen cryopreservation adopts a new cryoprotectant formula, which contains trehalose and taurine components in a specific ratio, which can increase the vitality of the frozen semen by 0.08 to 0.12 after thawing and recovery. The insemination process adopts a visual insemination device, which can visually observe the insemination position and improve the insemination success rate by 15% to 25%.

Secondly, the strict selection and introduction process, combined with comprehensive health examinations and special transportation and isolation measures, guarantees the quality and breeding safety of the introduced sika deer to the greatest extent, which is different from the conventional extensive selection and introduction model. In terms of feed supply, precise formula and advanced processing technology ensure nutritional balance and feed quality, which is in sharp contrast to the previous single feed supply method. In the health monitoring and disease prevention and control system, the high-precision monitoring system and scientific prevention and control means can timely warn and prevent diseases, which is superior to the traditional breeding lack of system Monitoring and effective prevention and control, ecological environment creation and maintenance, construction of multi-level vegetation, insect and bird areas and dynamic monitoring and optimization, forming a complete ecological chain, which was rarely involved in previous breeding, and the waste treatment and recycling model realized efficient resource utilization and reduced pollution, which was completely different from the traditional random disposal of waste. The breeding management and population optimization program systematically improved the population quality from file establishment, breeding care to genetic evaluation and elimination, while traditional breeding often lacked such a comprehensive breeding management strategy. In summary, the present invention significantly improved the breeding efficiency, ecological benefit and social benefit of sika deer, brought a new and sustainable development model to the sika deer breeding industry, and strongly promoted the progress and innovation of the industry. DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in combination with the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] The present invention will be further described below in conjunction with the embodiments.

[0038] Example 1: Site layout and construction:

[0039] Site selection and zoning:

[0040] An area of ​​15,000 square meters with undulating terrain was selected as the breeding site. The area has a natural water source with clear and pollution-free water. Protective facilities are installed at the water source to prevent sika deer from directly entering the polluted water source.

[0041] The site is divided into living and breeding area, sports and leisure area, feed planting area, and isolation and quarantine area. The areas are 5,000 square meters, 4,000 square meters, 3,000 square meters, and 3,000 square meters respectively. The areas are separated by 2.5-meter-high walls. At the bottom of the wall, there is a 0.5-meter-high anti-escape foundation to ensure that sika deer cannot cross the area.

[0042] Details of the construction of living and breeding areas:

[0043] The main frame of the living quarters is steel structure, with a frame column spacing of 2 meters. The outside of the frame is covered with fireproof and breathable glass wool board, the wall thickness is 12 cm, and the thermal conductivity of the wall material is 0.03 watts per meter Kelvin. The roof of the house is double-slope with a slope of 35 degrees. Solar panels and insulation felt are laid on the roof of the house. The area of ​​solar panels accounts for 50% of the roof area of ​​the house. The solar panels are connected to the power storage and conversion device in the house (using lithium iron phosphate battery pack with a capacity of 6000 ampere hours). It has intelligent charging and discharging management functions and can automatically adjust the charging and discharging strategy according to the sunshine conditions and the power demand in the house.

[0044] A four-layer wooden platform is set up inside the living house. The platform is 50 cm high and the guardrail on the edge of the platform is 30 cm high. The guardrail is made of antiseptic wood and is 10 cm apart to ensure the safety of the sika deer. The floor of the house is paved with a fermented mixture of sawdust, straw and probiotics in a ratio of 4:3:1. The thickness of the bedding is 18 cm and it is replaced every 90 days. When replacing, the house must be thoroughly cleaned and disinfected first.

[0045] The feeding trough and water trough are made of stainless steel, with a depth of 25 cm and 15 cm respectively. Both the feeding trough and the water trough are equipped with automatic cleaning and feeding control devices. The feeding control device can perform feeding operations according to the preset program (feeding 3 times a day, at 7 am, 12 noon and 5 pm respectively, and the feeding amount is set according to the growth stage and weight of the sika deer, with the error controlled within ±3%). The main frame of the steel structure is treated with an anti-rust coating with a coating thickness of 130 microns. The ventilation system of the living house adopts a multi-channel design, and the ventilation volume is 35% higher than that of ordinary ventilation systems. The vents are equipped with insect-proof nets to prevent mosquitoes from entering the house.

[0046] Example 2: Selection and introduction of sika deer:

[0047] Selection criteria:

[0048] Select sika deer between 2 and 4 years old and weighing between 50 and 80 kg. The physical appearance requirements are that the deer should have a well-proportioned body, healthy limbs without obvious deformities, shiny and intact fur without damage, bright and clear eyes without turbidity, and neat and complete teeth without missing teeth. At the same time, observe the mental state of the deer, which should be lively, active, and quick to react.

[0049] Comprehensive health check process and safe transportation measures:

[0050] Before introduction, the sika deer were given a comprehensive health check, and the blood routine test index required the red blood cell count to be (4.2-5.8)×10 12 / L, white blood cell count (4.5-10.5)×10 9 / L, platelet count (110-320) × 10 9 / L; parasite detection uses a combination of fecal sampling and serum testing. The number of parasite eggs in the feces does not exceed 8 / gram, and the parasite antibody test in the serum is negative;

[0051] Infectious disease screening targeted deer pox, deer pasteurellosis, and deer brucellosis using PCR testing technology, and the results were all negative.

[0052] Specially designed transport vehicles are used. The carriage is a closed structure. The adjustable partitions inside the carriage are made of plastic and aluminum alloy composite materials. The height of the partitions is 1.2 meters. The bottom of the carriage is paved with shock-absorbing and anti-slip padding. The padding is 8 cm thick and is made of rubber and polyester fiber materials mixed in a ratio of 6:4. The carriage is equipped with ventilation adjustment equipment (the air volume adjustment range is 13 cubic meters to 17 cubic meters per hour), temperature control equipment (the temperature in the carriage can be accurately controlled at 10°C to 20°C), and humidity adjustment equipment (the humidity in the carriage can be controlled at 48% to 62%) and real-time monitoring and data transmission devices (monitoring camera resolution 1080P, data transmission interval 5 minutes). The connection parts of the partition device adopt rubber sealing structure with good sealing performance. The vehicle's shock-absorbing and anti-skid padding has a self-cleaning function and can be washed with a high-pressure water gun to remove surface dirt. The transportation time is controlled within 7 hours. After arriving at the breeding site, it will directly enter the isolation and quarantine area for 45 days of isolation and observation. During the isolation period, a health check will be carried out every 5 days. The inspection items are the same as before introduction, and the inspection results are recorded in detail in the isolation observation file.

[0053] Example 3: Feed supply and management:

[0054] Precision feed formulation:

[0055] Feed formulas are formulated based on the different growth stages of sika deer (young deer, growing deer, adult deer), seasonal changes (spring, summer, autumn, winter) and gender differences, as shown in the following table (taking the spring formula for growing deer as an example):

[0056]

[0057]

[0058] Efficient feed processing and strict quality testing:

[0059] The feed processing adopts a mechanized processing line. The raw materials are first crushed to a particle size of 1.8 mm to 2.2 mm. Then they are mixed and stirred for 12 minutes. Finally, they are made into granular feed according to the feeding habits of sika deer. The diameter of the granular feed is 1.2 cm. The crushing device adopts a multi-stage crushing structure, which can crush the feed raw materials to a particle size of 0.3 mm to 0.7 mm. The mixing and stirring device adopts vacuum stirring technology. The vacuum degree is maintained at -0.06MPa to -0.08MPa during the stirring process, which effectively removes bubbles and improves the uniformity of feed mixing.

[0060] Feed quality inspection is carried out regularly, once every 45 days. The inspection contents include nutrient content determination (crude protein content not less than 15%, crude fat content not less than 3%, crude fiber content not higher than 20%, etc.), mildew detection (aflatoxin content not more than 15μg / kg, vomitoxin content not more than 1mg / kg, etc.) and heavy metal content detection (lead content not more than 3mg / kg, mercury content not more than 0.05mg / kg, arsenic content not more than 2mg / kg, etc.). The inspection results are recorded in the feed quality inspection report. If quality problems are found, the feed formula should be adjusted in time or the raw material supplier should be replaced.

[0067]

[0068] The vaccination dosage is determined based on the weight of the sika deer, with the error controlled within ±5%. The reaction of the sika deer is observed after vaccination, and any abnormalities are dealt with in a timely manner.

[0069] The breeding grounds are disinfected regularly, once every 6 days, using chemical disinfection (using sodium dichloroisocyanurate disinfectant at a concentration of 0.3%-0.6%) and physical disinfection (ultraviolet irradiation at an intensity of 80μW / cm 2 -100μW / cm 2 , irradiation time 30 minutes to 60 minutes) combined with the disinfection area, the disinfection area includes the living and breeding area, sports and leisure area, feed planting area and isolation and quarantine area. After disinfection, the plate counting method is used to detect the disinfection effect. The bacterial killing rate reaches more than 98%. The disinfection process is recorded in the disinfection record file.

[0070] Example 5: Ecological environment creation and maintenance:

[0071] Reasonable vegetation planting and monitoring:

[0072] A variety of plants are planted around the breeding grounds and in the sports and leisure areas.
