Description

Technical Field

[0001] This invention relates to the field of Baer's Pochard breeding technology, and in particular to a method and system for artificial brooding and raising of weak chicks of Baer's Pochard. Background Technology

[0002] The Baer's Pochard is a critically endangered species. The mortality rate of Baer's Pochard chicks is as high as 72.7% within the first month of life, mainly due to hypothermia, nutritional deficiencies, stress, and predation by predators. Existing warming techniques, primarily based on standards for other waterbirds, have failed to meet the specific needs of the Baer's Pochard, resulting in impaired digestion, development, and immune systems that prevent them from surviving the high-risk mortality period of their first month.

[0003] In addition, Baer's Pochard chicks are prone to fighting and trampling accidents during mixed rearing, and are easily injured, mainly in the head, beak, wings and feet. The mixed rearing model leads to malnutrition due to their poor ability to compete for food, especially in terms of protein requirements, and their molting is relatively delayed. Baer's Pochard chicks have a higher probability of dying from stress than other waterbird chicks.

[0004] One of the species-specific characteristics of the Baer's Pochard is its extreme sensitivity. The Baer's Pochard is smaller in size and more prone to stress, resulting in more screeching and aimless running around. It is a highly stressed species. In the past, the cages used for raising Baer's Pochards were too large, making it difficult to catch them. The process of catching them could easily cause collisions, which would affect their later breeding. In addition, the traditional cement floor caused Baer's Pochard chicks to develop footpad hyperplasia and fleshy spines. Furthermore, improper swimming time and methods led to an imbalance in muscle and wing development.

[0005] Overall, improving the survival rate, healthy development, and socialization capacity of Baer's Pochard is crucial for population conservation, expansion, and reintroduction into the wild. Currently, domestic regulations for the management of wild birds mainly cover common waterbirds such as mallards and spot-billed ducks, and there are no regulations for the breeding of rare and endangered pochard species.

[0006] Therefore, there is an urgent need for a method and system for artificial brooding and raising of weak chicks of Baer's Pochard to overcome the problems of high deformity rate of Baer's Pochard chicks, easy injury during mixed rearing, unhealthy development, and high mortality rate due to weak chicks being unable to feed independently and being thin and weak. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to provide a method for artificial brooding and raising of weak chicks of Baer's Pochard, so as to ensure that Baer's Pochard chicks safely pass through the high mortality risk stage within the first month of age, improve their overall health, and ultimately promote subsequent reproduction and survival.

[0008] To solve the above-mentioned technical problems, the present invention provides a method for artificial brooding and weak chick rearing of Baer's Pochard, comprising the following steps: First rearing stage: keeping Baer's Pochard chicks aged 1 to 3 days warm and monitoring their weight;

[0009] Second nursery stage: Adjust the environmental temperature for Baer's Pochard chicks aged 4-10 days, lowering the first environmental temperature to the second environmental temperature, and keep the Baer's Pochard chicks warm and nurtured.

[0010] Nutrients were supplied to 4-10 day old Baer's Pochard chicks using a quantitative feeding method.

[0011] A health assessment system was developed for Baer's Pochard chicks aged 4 to 10 days.

[0012] For 4-10 day old Baer's Pochard chicks, a phased net cage and a stepped swimming pool were set up, and the first phase of functional training was carried out based on the first-stage feeding net cage, the first-stage swimming pool and the second-stage swimming pool.

[0013] The third nursery stage: Health monitoring and nutritional adjustments are carried out for Baer's Pochard chicks aged 11 to 30 days. Based on the second-stage feeding cages and the third-stage swimming pool, the second-stage functional training is carried out.

[0014] As an improvement of the present invention, 1-3 day old Baer's Pochard chicks are placed in an incubator for 2-6 hours. After the down feathers of the Baer's Pochard chicks are completely dry, they are placed in an incubator and the temperature inside the incubator is set to 36-35°C. The set temperature is lowered by 0.5-1°C every day.

[0015] After placing the young Baer's Pochard in the incubator for 11 to 13 hours, give them boiled water that has been cooled to a temperature of 36 to 37°C.

[0016] After placing the young Baer's Pochard ducklings in the incubator for 20-36 hours, feed them pelleted feed and water simultaneously, with a feed amount of 2-3g per duckling.

[0017] The health status of Baer's Pochard chicks was monitored and tracked when they were not fed, and a chick weight curve was plotted.

[0018] As an improvement of the present invention, in the second nursery stage, the environmental temperature of the Baer's Pochard chicks is adjusted based on the incubator, and the first environmental temperature is set to 35-34°C.

[0019] For healthy Baer's Pochard chicks, the first ambient temperature should be lowered to a second ambient temperature of 29-28°C within 7-10 days of age;

[0020] For the weak Baer's Pochard chicks, a gradual cooling process was implemented, lowering the first ambient temperature to a second ambient temperature of 29–28°C.

[0021] As an improvement of the present invention, in the second nursery stage, a quantitative feeding method is used to provide nutrition to 4-10 day old Baer's Pochard chicks, including:

[0022] Feed the 4-10 day old Baer's Pochard chicks the above-mentioned quantitative feeding, provide them with boiled and cooled water, and add nutritional supplements;

[0023] The quantitative feeding method includes:

[0024] Feed the animals a fixed amount of pelleted feed and mealworms, 5 to 6 times a day, with a feeding interval of 2 to 3 hours.

[0025] For feeding 4-day-old Baer's Pochard chicks, the initial feed amount per chick is set at 4-5g, and the final feed amount at the last feeding of the day is set at 1.5-2 times the previous amount.

[0026] For 4-day-old Baer's Pochard chicks, feed them 3 mealworms each time. For each additional day the chicks grow, increase the amount by 3 mealworms per feeding.

[0027] As an improvement of the present invention, a health assessment system is established for 4-10 day old Baer's Pochard chicks in the second nursery stage, including:

[0028] The first weight monitoring, fecal collection, behavioral observation and morphological development of 4-10 day old Baer's Pochard chicks were conducted to establish a health assessment system.

[0029] As an improvement to the present invention, the first stage of functional training includes:

[0030] The first-stage breeding cages are designed in a modular, phased manner, with precise management, environmental regulation, and safety protection features.

[0031] Based on the observation and monitoring conducted in the first stage of the caged animal rearing, the companionship method for companion animals was adjusted to be outside the cage.

[0032] Based on the first stage of feeding net cages, a cage-within-a-cage method for raising weak chicks was implemented.

[0033] Sunbathing 4-5 day old Baer's Pochard chicks promotes synchronous development of their physical functions;

[0034] The first-stage rearing cages were set up for 4-10 day old ducklings, and the 4-10 day old Baer's Pochard ducklings were reared in groups of 5-10.

[0035] As an improvement to the present invention, the first stage of functional training further includes:

[0036] The first-stage swimming pool was used to conduct the first water trial for 5-day-old Baer's Pochard chicks.

[0037] Based on the second-stage swimming pool, 10-day-old Baer's Pochard chicks were tested in the water for 5 to 10 days;

[0038] Increase the swimming time and frequency of Baer's Pochard chicks after 10 days of age;

[0039] The first-tier swimming pool uses tap water that has been exposed to sunlight, while the second-tier swimming pool uses natural lake water.

[0040] As an improvement of the present invention, the third conservation stage includes:

[0041] During health monitoring, a second weight monitoring, fecal collection, behavioral observation, and morphological development assessment were conducted on Baer's Pochard chicks aged 11–30 days.

[0042] Nutritional adjustments are made to Baer's Pochard chicks, including:

[0043] Feed 11-15 day old Baer's Pochard chicks vegetables, providing vegetable leaves and processing them into small pieces;

[0044] Adjust the feeding amount and feed soft feed, mealworms, and pellet feed. The soft feed is a mixture of pellet feed, chopped vegetables, and chopped eggs.

[0045] Adjusting the drinking water for Baer's Pochard chicks, the adjustment of drinking water includes:

[0046] Add sun-exposed tap water to boiled lukewarm water. The initial ratio is 5:1 to 3:1, and it is used for Baer's Pochard chicks aged 5 to 10 days.

[0047] Baer's Pochard chicks aged 10-15 days can drink tap water that has been exposed to the sun directly.

[0048] Baer's Pochard chicks aged 15-30 days drink water from the third-stage swimming pool mixed with water from the natural lake.

[0049] As an improvement to the present invention, the third conservation stage further includes:

[0050] The second phase of functional training for Baer's Pochard chicks includes:

[0051] Based on the second-stage breeding cage, modular and phased design, precise management design, environmental regulation, and safety protection design are adopted;

[0052] Based on the observation and monitoring conducted in the second stage of the caged animal rearing, the companionship method for companion animals was adjusted to be outside the cage.

[0053] Based on the second stage of feeding net cages, a cage-within-a-cage method for raising weak chicks was implemented.

[0054] Daytime swimming behavior training was conducted on Baer's Pochard chicks aged 11 to 30 days.

[0055] The second stage of rearing net cages were set up for 11-30 day old ducklings, and the 11-30 day old Baer's Pochard ducklings were reared in groups of 5-6.

[0056] Swimming training is conducted using the third-tier swimming pool, transitioning from the second-tier pool to the third-tier pool;

[0057] Natural lake water is added to the third-tier swimming pool, and the water-to-volume ratio in the third-tier swimming pool is 1:3 to 1:2, with a water temperature of 30 to 35℃, based on the filtration of the water purification box.

[0058] As another improvement of the present invention, a system for artificial brooding and weak chick rearing of Baer's Pochard includes:

[0059] The first-stage feeding cage and the second-stage feeding cage are divided into a first-stage feeding cage and a second-stage feeding cage. The first-stage feeding cage is used to raise 4-10 day old Baer's Pochard chicks, and the second-stage feeding cage is used to raise 11-30 day old Baer's Pochard chicks. The first-stage feeding cage and the second-stage feeding cage are respectively equipped with inner cages to protect weak chicks.

[0060] The stepped swimming pool includes:

[0061] First-tier swimming pool, second-tier swimming pool, and third-tier swimming pool;

[0062] The first, second, and third tiered swimming pools are arranged in a stepped manner from low to high, adjacent to each other, to gradually transition the water pressure in the pools and train the young birds' jumping and diving strength.

[0063] With this design, the present invention has at least the following advantages:

[0064] 1. By utilizing an optimized heat preservation strategy during the first nursery stage, the high mortality rate caused by temperature discomfort and insufficient nutrition during yolk absorption and the initial stage is reduced, ensuring the safe transition of chicks.

[0065] 2. By designing a precise temperature control program and a scientific nutrition supply process in the second nursery stage, the temperature at each stage is adjusted in a timely manner to adapt to different developmental needs. A precise feeding method with fixed time and quantity is implemented to ensure that the chicks have sufficient nutrition intake, support healthy and stable weight gain and feather renewal, optimize gastrointestinal function, and reduce the occurrence of diseases.

[0066] 3. By establishing a phased net cage, a safe and interactive rearing environment is provided, reducing stress response and promoting the healthy growth and social integration of chicks. The cage-within-a-cage structure protects weak chicks while promoting their group interaction. The safe design and interactive modular settings meet different physiological and behavioral needs, while significantly improving management efficiency and monitoring accuracy, effectively avoiding the risks of injury and deformity caused by traditional large net cages.

[0067] 4. Enhance behavioral training through tiered swimming pools, creating multi-level swimming depths to support the transition of Baer's Pochard chicks from shallow to deep water, strengthen their muscle and preen gland development, and reasonably arrange sunbathing and exercise time to effectively promote vitamin D synthesis and reduce stress.

[0068] 5. A feeding and care program specifically designed for weak chicks ensures their effective integration into the group, improves developmental disparities, enhances overall community stability, improves competition for food and reproductive potential, and provides a solid foundation for subsequent population expansion and reintroduction into the wild.

[0092] This invention provides a method for artificial brooding and rearing of weak chicks of Baer's Pochard. Based on five years of monitoring and data collection, improvements were made to address the high mortality rate of 72.7% in Baer's Pochard chicks within one month of age. Within one month of age, chicks will undergo key stages such as yolk absorption, development of the body temperature system, increase in body mass index, and post-molting. Each stage presents different survival challenges. This invention organically combines these key developmental nodes to achieve a reasonable transition.

[0093] Figure 1 This is a schematic diagram of the method flow for artificial brooding and weak chick rearing of Baer's Pochard provided in the embodiments of this disclosure.

[0094] like Figure 2 As shown, during the first nursery stage, 1-3 day old Baer's Pochard chicks were kept warm and their weight was monitored.

[0095] In this embodiment of the invention, the first conservation stage includes:

[0096] like Figure 1 , Figure 2 And refer to Figure 15 and Figure 16 As shown, 1-3 day old Baer's Pochard chicks were placed in an incubator for 2-6 hours until their down feathers were completely dry. They were then transferred to a warming box with the temperature set at 36-35°C. This temperature was lowered by 0.5-1°C daily. After 12 hours in the warming box, the chicks were given boiled water cooled to 36-37°C. After 24 hours in the warming box, they were fed pelleted feed at a rate of 2-3g per chick, preferably 2g per chick. The chicks' weight was monitored and their health status tracked before feeding, and a chick weight curve was plotted.

[0097] Specifically, Baer's Pochard chicks primarily absorb the yolk sac during their 1-3 day old age, exhibiting a "false liveness" state. Prolonged stay in the incubator leads to significant down loss due to the fan. Therefore, the incubator time should be adjusted to 2-6 hours to reduce down shedding. Rapid yolk sac absorption can cause weight loss and hinder recovery; therefore, the insulation strategy should be adjusted. Once the down is completely dry, the chicks should be placed in an incubator with a set temperature of 36-35°C. The temperature should be lowered by 0.5-1°C daily to prevent excessive yolk sac depletion. After 11-13 hours in the incubator, the chicks should be given boiled water cooled to a temperature of 36-37°C. Maintaining a suitable temperature (℃) protects the digestive system and promotes nutrient absorption. Baer's Pochard chicks should be placed in an incubator for 20-36 hours before being fed pelleted feed, at a rate of 2-3g per chick. Ideally, feed should be given earlier if meconium has been expelled, and later if not. Water should be provided throughout the process. Zhengda 520 or 521 pelleted feed is preferred, as it promotes nutrient absorption and weight gain. A weight curve should be plotted for chicks experiencing rapid weight loss. Good and stable insulation is crucial for chicks to safely survive the high-risk mortality period of their first month, promoting growth and development, reducing energy consumption, minimizing stress from low temperatures, and enhancing immunity.

[0098] like Figure 1 and combined Figures 3 to 14 As shown, during the second nursery stage, the environmental temperature was adjusted for 4-10 day old Baer's Pochard chicks, and the first environmental temperature was lowered to the second environmental temperature to keep the Baer's Pochard chicks warm and nurtured.

[0099] Nutrients were supplied to 4-10 day old Baer's Pochard chicks using a quantitative feeding method.

[0100] A health assessment system was developed for Baer's Pochard chicks aged 4 to 10 days.

[0101] For 4-10 day old Baer's Pochard chicks, a staged net cage 100 and a stepped swimming pool 200 are set up. The first stage of functional training is carried out based on the first stage feeding net cage 110, the first stepped swimming pool 210 and the second stepped swimming pool 220.

[0102] In this embodiment of the invention, during the second nursery stage, the environmental temperature of Baer's Pochard chicks is adjusted based on the incubator. The first environmental temperature is set to 35-34°C. For healthy Baer's Pochard chicks, the first environmental temperature is lowered to a second environmental temperature of 29-28°C within 7-10 days of age. For weak Baer's Pochard chicks, the temperature is gradually lowered to the second environmental temperature of 29-28°C.

[0103] Specifically, Baer's Pochard chicks have poor thermoregulation during their downy plumage stage, making them more prone to exhibiting lower body temperatures in their beaks and feet. Therefore, the ambient temperature should be gradually lowered from 35-34℃ to around 29-28℃. Healthy chicks should complete this process around 7-10 days of age, while weaker chicks should complete it around 10-15 days of age. Steady warming measures can reduce animal stress and decrease the incidence of diarrhea, shivering, or even early death due to hypothermia.

[0104] In this embodiment of the invention, during the second nursery stage, a quantitative feeding method is adopted for the 4-10 day old Baer's Pochard chicks to provide nutrition. This includes providing the 4-10 day old Baer's Pochard chicks with the quantitative feeding method, drinking boiled and cooled water, and adding nutrient agents. The quantitative feeding method includes feeding quantitative pellets and mealworms, with an average of 5-6 feedings per day and a feeding interval of 2-3 hours. For 3-day-old Baer's Pochard chicks, the initial feed amount per chick is set at 4-5g, preferably 3.8g. The final feed amount at the last feeding of the day is set at 1.5-2 times that of the previous feeding. For 3-day-old Baer's Pochard chicks, 3 mealworms are fed each time. For each additional day of growth of the Baer's Pochard chicks, 3 more mealworms are added per feeding.

[0105] Specifically, 4-10 day old Baer's Pochard chicks often experience problems such as slippery tendons and diarrhea. Weak chicks may show slow or even decreased weight gain, requiring adjustments to nutrition and the development of a specialized care plan. Nutrition should consist of quantitative feeding of pelleted feed (520 / 521) and mealworms, 5-6 times daily, with 2-3 hour intervals between feedings. For 3-day-old Baer's Pochard chicks, the average feed amount is 3.8g per feeding per chick. Any leftover feed should be collected and weighed after each feeding, with a reduced amount for the next feeding. If there is no leftover feed, the amount should be increased for the next feeding. The last feeding of the day should be 1.5-2 times the amount of the previous feeding, with adjustments made based on whether there is any leftover feed the following day. For 3-day-old Baer's Pochard chicks, feed them 3 mealworms per feeding per chick, with an additional 1-2 mealworms for weaker chicks. Increase the amount by 3 mealworms per chick per day per feeding, adjusting based on fecal condition. Ensure that the chicks drink boiled water at a lukewarm temperature. Add nutritional supplements, preferably poultry multivitamins and poultry cod liver oil.

[0106] It should be noted that this invention describes the feeding tools and methods. The feed container for chicks aged 4 to 10 days should not be too large, just large enough so that each chick has its own feeding spot. The inside of the container should not be smooth to prevent the chicks from slipping when competing for food. Small poultry waterers should be used for chicks aged 3 to 10 days to prevent the chicks from getting wet and getting cold or the umbilical cord of weak chicks from getting infected.

[0107] This invention also provides another feeding method, focusing on the weight and nutrition of weak chicks during this period, and helping them integrate into the group to shorten the developmental gap. If weak chicks cannot feed themselves, 4-5 pellets of feed can be soaked in warm water, mashed into a paste with 2-3 mealworms, and placed into a 2-2.5ml syringe (without the needle). The paste is then pushed out about 2mm and gently touched to the lower edge of the chick's beak to stimulate it to open its mouth and put the feed in to supplement nutrition. After weak chicks can feed themselves, if their ability to compete for food is poor, a cage-within-a-cage method can be used to ensure they can eat and communicate with the group.

[0108] In this embodiment of the invention, the second nursery stage includes establishing a health assessment system for 4-10 day old Baer's Pochard chicks, which involves the first weight monitoring, fecal collection, behavioral observation, and morphological development of the 4-10 day old Baer's Pochard chicks, and establishing a health assessment system.

[0109] Specifically, weight monitoring is conducted. The weight curve of 1-month-old Baer's Pochard chicks shows a logistic "S" curve, which will experience a period of weight loss, steady growth, and rapid growth. The average weight of 4-10-day-old Baer's Pochard chicks will steadily increase from 25g at birth to 60g. If the chicks show a significant weight loss, special attention should be paid and measures should be taken in a timely manner.

[0110] Furthermore, fecal collection and testing are conducted. Baer's Pochard chicks excrete dark green meconium at 1-2 days of age. They begin to eat pelleted feed at 4-10 days of age. Healthy feces should be yellow, formed, and dry with no odor. If brown, tan, watery, mucousy, or foul-smelling feces are found, testing should be performed as soon as possible and treatment should be initiated.

[0111] Further behavioral observation is necessary. The earliest and best time to distinguish between healthy and weak chicks is between 4 and 10 days old. Healthy chicks are lively and energetic, feed independently, have warm feet, bright eyes, a clear sense of direction, and can quickly catch moving objects. Weak chicks are sluggish, do not feed actively, stand unsteadily, have cold feet, poor sense of direction, and low light sensitivity. Chicks aged 4 to 10 days exhibit fewer behaviors, mainly group exploration, feeding, and drinking, and rarely stray from the flock. If they appear listless or lie down for extended periods, extra attention should be paid.

[0112] Furthermore, in terms of morphological development, the Baer's Pochard, due to its excellent diving ability and molting after juvenile stage, is smaller in size, with thick and short tarsi and large and thick webbed feet. Therefore, during its growth and development period, it has higher requirements for wing development and is more prone to abnormal development of legs and feet than other birds.

[0113] The following describes the first stage of functional training in the second stage of conservation, including modular and phased design, precise management design, environmental regulation, and safety protection design for the first stage breeding cage 110.

[0114] Based on the observation and monitoring of the first-stage breeding cage 110, the companion animal companionship method was adjusted to be cage-free companionship.

[0115] Based on the first-stage feeding cage 110, a cage-within-a-cage method for raising weak chicks was implemented.

[0116] Sunbathing 4-5 day old Baer's Pochard chicks promotes synchronous development of their physical functions;

[0117] The first-stage rearing cage 110 was set up as a cage for 4-10 day old ducklings, and the 4-10 day old Baer's Pochard ducklings were reared in groups of 5-10.

[0118] In this embodiment of the invention, two modular, phased net cages are designed: a first-stage rearing net cage 110 for 4-10 day old animals and a second-stage rearing net cage 120 for 10-30 day old animals. The following is a specific implementation of the net cage for the 4-10 day old animal stage.

[0119] Specifically, Baer's Pochard chicks were raised in groups of 5 to 10. The net cages were set with two mesh sizes: 3*2*2 (105*70*70cm) and 2*2*2 (70*70*70cm). This solved the problem that the chicks were very small at this stage, had few down feathers, and were prone to squeezing into corners. The chicks in the early stages tended to huddle together for warmth. If the animals scattered, the isolated individuals would suffer from hypothermia and die. In addition, it reduced the stress on the chicks by reducing the space appropriately, which reduced the impact force after the chicks took off running and caused a high rate of deformities.

[0120] Furthermore, to facilitate real-time observation of chicks' behavior and health status by caregivers and achieve precise management, and to ensure that the spacing between the cage doors is suitable for safe, blind-spot-free operation by human upper limbs, a single-module animal access door was designed at the bottom of the cage for chicks to freely enter and exit, reducing interference and accidental injury caused by human handling, and enhancing animal behavior training. Simultaneously, a single-module manual access door was designed at the top diagonally for collecting feces, placing food and water, and assisting in animal behavior training. The animal access door and the manual access door serve different functions, which are beneficial for reducing stress levels in chicks, stimulating natural behaviors, and providing health care.

[0121] It should be noted that in this invention, the staged net cage 100 is equipped with horizontal grids (35cm*35cm) for placing incandescent lamps (which emit light but do not heat), heat lamps (which emit light and heat), or night lights (which emit light but do not heat) as the main means of controlling the built-in microenvironment, to prevent them from falling and injuring the chicks; in the event of extremely hot and humid weather, air circulation facilities can also be installed here to create a more stable microclimate and reduce stress caused by changes in the external environment.

[0122] For example, in this invention, the staged net cage 100 uses two soft materials to cover the edges and bottom of the cage and lay them on the ground below the net cage to reduce the risk of collision and pinching, and protect the feet of the chicks; one is a 3.5mm thick, S-patterned hollowed-out PVC soft pad, and the other is a 1.5mm thick, latex anti-slip PVC soft pad; the first type of soft pad is preferred for safety protection. In this invention, the mesh size of the staged net cage 100 is designed to be moderate to prevent chicks from escaping and to prevent intrusion by external predators.

[0123] Furthermore, the monitoring equipment at the right angle of the upper layer of the staged net cage 100 helps caregivers observe the behavior and health status of the chicks in real time, enabling precise management. The companionship methods of other ducks and birds are adjusted to outside the cage, and safety fences are used to prevent them from escaping. This can promote the active feeding and warmth of Baer's Pochard chicks, provide psychological support through group interaction, and avoid interspecies competition.

[0124] Specifically, this invention provides a cage-within-a-cage method for raising weak chicks, offering a safe space for weak chicks to be protected and prevent them from becoming separated from the flock. It allows them to maintain communication with the main cage group, promoting psychological stability. An inner cage composed of a single-piece mesh with a length-width-height ratio of 1*1*1 is installed within a staged mesh cage 100, with an entrance on one side. This inner cage can be flexibly placed in different stage cages, offering unrestricted visibility and protecting weak chicks and injured individuals within the flock. It facilitates individual feeding and treatment. The inner cage can be placed in the middle of different stage mesh cages, not against the walls, facilitating flock gathering and communication. The cage structure can also be periodically adjusted to adapt to the spatial and social needs of different stages, ensuring proper care for both weak and healthy chicks.

[0125] More specifically, adjust the exercise time and method in the cage, and advance the time for young birds to receive sunbathing to 3-5 days old to promote the synchronous development of various physical functions. The minimum temperature of the outdoor ground and air should be 28-29℃. The activity area for chicks should avoid direct sunlight and should be shaded by trees or have a dappled environment.

[0126] Specifically, the recommended sunbathing time for Baer's Pochard chicks in North China is 9:00-10:00 AM and 3:00-5:00 PM. The specific time and duration need to be adjusted according to the latitude, season, and climate of the breeding site. This measure is beneficial for the synthesis of vitamin D, the regulation of the body temperature system, and the reduction of stress rate in Baer's Pochard chicks.

[0127] As shown in the figure Figure 11 The diagram shown is a schematic representation of the structure of the stepped swimming pool in this invention.

[0128] The following describes the first stage of functional training in the second nursery stage, which also includes the initial water trial of 5-day-old Baer's Pochard chicks in the first-tier swimming pool 210.

[0129] The second-stage swimming pool was used to conduct a 5-10 day trial swim on 220 pairs of 10-day-old Baer's Pochard chicks.

[0130] Increase the swimming time and frequency of Baer's Pochard chicks after 10 days of age;

[0131] The first-stage swimming pool 210 uses tap water that has been exposed to sunlight, while the second-stage swimming pool 220 uses natural lake water.

[0132] Specifically, the 200 stepped swimming pool adopts a multi-step design, with each step providing different water depths to allow Baer's Pochard chicks to gradually adapt to water depths, especially the transition from shallow to deep water, promoting the development of the chicks' preen glands, wing muscles, and legs and feet, and enabling them to develop synchronously.

[0133] The specific experimental data are shown below:

[0134] Baer's Pochard chicks, at 5 days old, have legs that are 5-6 cm long and can jump 2-3 cm high. Therefore, the first-tier swimming pool (210) is designed with dimensions of 120*80*8 cm and a water level difference of 2-3 cm. This size is suitable for 5-10 chicks to try swimming for the first time, and the water depth of 5-6 cm is suitable for 5-day-old chicks. The second-tier swimming pool (220) has dimensions of 120*100*18 cm and a water level difference of 3 cm. This size is suitable for 5-10 chicks to jump independently after swimming progress, and the water depth of 15 cm is suitable for 10-day-old chicks to try swimming for 5-10 days. The third-tier swimming pool (230) has dimensions of 120*100*30 cm and a water level difference of 3-5 cm. This size is suitable for 5-10 chicks to jump independently after swimming progress, and the water depth of 25-27 cm is suitable for 15-20-day-old chicks to try swimming for 10-15 days. The tiered swimming pool 200 offers three different water depths, allowing young Baer's Pochards to gradually adapt to the water depth and flexibly choose between different areas, including transitioning from shallow to deep water and freely choosing between deep and shallow areas.

[0135] It should be noted that the present invention incorporates safety protection design for the tiered swimming pool 200, adding anti-slip plates and soft mats to prevent chicks from slipping or accidentally falling. The first tiered swimming pool 210 needs to be equipped with three tiers with an angle of less than 30°, as chicks tend to enter the water through the tiers and like to rest and preen their feathers on them. These tiers can be independent or fixed; preferably, independent tiers are chosen for their flexibility in placement and movement. All tiered swimming pools 200 must be equipped with movable anti-slip plates (with soft mats on top, the same specifications as the net cage mats). The preferred parameters are: the first tiered swimming pool 210 has dimensions of 120cm*8cm, and the second and third tiered swimming pools have dimensions of 120cm*15cm. The wide edge of the anti-slip plate should fasten to the edge of the pool for easy disassembly and movement. The application of anti-slip plates is closely related to the ecological habits of ducklings. After swimming, Baer's Pochard ducklings need to flap their wings repeatedly to promote muscle growth, and they also need to preen their feathers and rest to restore their body temperature and strength, and stimulate the secretion of oil from the preen gland. The anti-slip plate is a key design for duckling swimming training.

[0136] Specifically, intelligent water level sensing is added, and low water level sensors are set up to identify and alarm. Preferably, automatic water storage and automatic water supply devices can be installed in the pool. A water purification device is set up to filter, drain, and disinfect the water in the stepped swimming pool 200 to support the healthy growth of chicks. Drainage holes are set in the stepped pool, and the excrement is fermented and used as fertilizer after being discharged.

[0137] Furthermore, this invention introduces biomimetic materials and natural landscape simulation to create a more natural swimming experience and help chicks reduce their sense of unfamiliarity. By adding aquatic plants and fish and shrimp, a more natural swimming experience is created to help chicks transition to the wild. Aquatic plants are added to the second-tier swimming pool 220, and aquatic plants, lotus leaves, and live organisms such as fish, shrimp and snails are added to the third-tier swimming pool 230.

[0138] The present invention provides swimming training control data for young Baer's Pochards as shown below:

[0139] The stepped swimming pool is designed according to the biological development of Baer's Pochard chicks. The gradual transition of water pressure helps train the chicks' jumping and diving strength, avoiding stress and hypothermia. The stepped pool allows for the control of swimming time and frequency. Chicks aged 5-10 days swim twice daily, with the first swim lasting 5 minutes. This time should be gradually increased based on the chicks' performance. If the chick's back feathers are dry after entering the water, the second day's swim can be increased by 5 minutes. If the chick's back feathers are exposed or it quickly jumps out of the pool, the time should not be increased, and so on. After 10 days, healthy chicks will no longer have wet back feathers after entering the water and can swim 2-3 times daily for 40 minutes to 1 hour each time. Weaker chicks should have their swimming time adjusted according to their condition, with an appropriate time of 20-30 minutes. After 20 days, the difference between weak and healthy chicks decreases, and they can swim 3 times daily. Each session should last 50 minutes to 1 hour. After 30 days of age, there are no restrictions on the swimming time and frequency for chicks, but they should avoid swimming during the peak of sunlight, i.e., 12:00 to 14:00. The ideal swimming times are between 9:00 to 11:00 and 15:00 to 17:00. The first-tier swimming pool 210 should be filled with tap water that has been exposed to sunlight. After the chicks enter the second-tier swimming pool 220, in addition to tap water, add 200-500 ml of water from a natural lake or body of water each day to help them gradually adapt to the wild aquatic environment and avoid stress during release into the wild. After the chicks enter the third-tier swimming pool 230, ensure that the pool contains 1 / 3 to 1 / 2 natural water and is filtered by a water purifier. The water temperature should be maintained at around 30-35℃. After each water change, the water should be exposed to sunlight before use.

[0140] The third nursery stage is described below, which includes a second weight monitoring, fecal collection, behavioral observation, and morphological health assessment of 10- to 30-day-old Baer's Pochard chicks during health monitoring.

[0141] Nutritional adjustments should be made for Baer's Pochard chicks, including:

[0142] Feed vegetables to 10-15 day old Baer's Pochard chicks, providing vegetable leaves and processing them into small pieces;

[0143] Adjust the feeding amount and feed soft food, mealworms, and pellets. Soft food is pellets mixed with chopped vegetables and chopped eggs.

[0144] Adjusting the drinking water for Baer's Pochard chicks, the adjustment of drinking water includes:

[0145] Add sun-exposed tap water to boiled lukewarm water. The initial ratio is 5:1 to 3:1, preferably 4:1, for use on 5-10 day old Baer's Pochard chicks.

[0146] Baer's Pochard chicks aged 10-15 days can drink tap water that has been exposed to the sun directly.

[0147] Baer's Pochard chicks aged 15-30 days drink water from the third-level swimming pool mixed with water from the natural lake.

[0148] Specifically, during weight monitoring, the average weight of Baer's Pochard chicks aged 11 to 30 days will increase from 60g to 270g, entering a period of rapid growth and development. If the chicks experience a continuous weight loss for more than two days at this time, it is the primary signal that the chicks have health problems and should be given special attention.

[0149] Specifically, when collecting feces, start adding small amounts of spinach, lettuce, carrots, and aquatic plants to the diet of 11-30 day old Baer's Pochard chicks. Healthy feces should be yellow-green, formed, dry, and odorless. If brown, tan, watery, mucousy, or foul-smelling feces appear, tests should be conducted as soon as possible and treatment should be given.

[0150] Specifically, behavioral observations show that 11-30 day old chicks exhibit an increased variety of behaviors, including basic behaviors such as preening, swimming, diving, feeding, and resting, as well as social behaviors such as playing, competing for food, and hiding. There is mutual learning and information exchange among the group. If a chick becomes isolated or exhibits lethargic or listless behavior, the cause should be investigated promptly.

[0151] Specifically, during the final stage of morphological development, 11-30 days old chicks have completed most of their post-molting, transitioning from tertiary flight feathers to secondary flight feathers. There are still a few downy feathers on the breast and back feathers. If an individual is found to be molting late, their nutrition should be adjusted promptly. Because chicks grow rapidly between 11 and 30 days old, the pressure on their feet increases sharply, making this period a high-risk period for footpad hyperplasia. Extra attention should be paid to balancing weight, muscle development, and activity levels.

[0152] In this embodiment of the invention, specific steps are provided for nutritional adjustment of chicks aged 11-30 days. Chicks should be fed vegetables starting at 10-15 days of age. To avoid choking, leafy parts (such as rapeseed or lettuce) should be provided, and the vegetables should be finely chopped. The amount should be gradually increased from small amounts. The feeding amount should be adjusted during this period: generally, the first meal should consist of a sufficient amount of soft feed (granular feed + chopped vegetables + chopped egg); the second meal should consist of a small amount of soft feed; and the third meal should consist of chopped vegetables + mealworms. The mealworms should be fed 5-6 per day. For the fourth feeding, feed each chick a sufficient amount of Zhengda pelleted feed; for the last feeding, provide each chick with 10 mealworms (approximately 50g); water adjustment: after chicks are 5-10 days old (healthy chicks start at 5 days old, weak chicks can start at 10 days old), each time, mix cooled boiled water with sun-exposed tap water, the initial ratio is 4:1, after 10-15 days old, they can drink only sun-exposed tap water, after 15-30 days old, the animals can drink water from the swimming pool mixed with natural lake water (synchronized with the 200-meter stepped swimming pool).

[0153] The third nursery stage also includes the second stage of functional training for Baer's Pochard chicks, which includes:

[0154] Based on the second-stage breeding cage 120, modular and phased design, precise management design, environmental regulation and safety protection design are carried out;

[0155] Based on the observation and monitoring of the second-stage breeding cage 120, the companion animal companionship method was adjusted to be cage-free companionship;

[0156] Based on the second stage of rearing net cage 120, a cage-within-a-cage method for raising weak chicks was implemented.

[0157] Daytime swimming behavior training was conducted on Baer's Pochard chicks aged 11 to 30 days.

[0158] The second-stage rearing net cage 120 was set up as a net cage for the 11-30 day age stage, and the 11-30 day age Baer's Pochard chicks were reared in groups of 5-6;

[0159] Swimming training is conducted in the third-tier swimming pool 230, transitioning from the second-tier swimming pool 220 to the third-tier swimming pool 230;

[0160] Natural lake water is added to the third-stage swimming pool 230, and the water-to-volume ratio in the third-stage swimming pool 230 is 1:3 to 1:2, and the water temperature is 30 to 35℃, based on the filtration of the water purification box.

[0161] Specifically, the second-stage rearing net cage 120 is used to raise Baer's Pochard chicks aged 11-30 days. The second-stage rearing net cage 120 is designed with a length-width-height ratio of 4*2*2, or 140*70*70cm. The second-stage rearing net cage 120 is independent of the first-stage rearing net cage 110; the two different rearing net cages are used to raise different groups. The area of ​​the second-stage rearing net cage 120 is suitable for 5-6 chicks. Different numbers of net cages can be made according to the number of chicks for precise rearing management.

[0162] More specifically, chicks aged 11–30 days have gradually adapted to the second-stage swimming pool 220, while healthy chicks transition to the third-stage swimming pool 230. It should be noted that the swimming needs of weak chicks and healthy chicks are different, and the swimming time should be adjusted accordingly. Game training should be designed to meet the unique developmental requirements of Baer's Pochard chicks to avoid chick stress, slippage, wing drop, developmental delays, and other issues, thereby reducing the impact on their subsequent survival abilities such as flight and escape, as well as their reproductive abilities such as mate selection.

[0163] As shown in the figure, the present invention also provides a system for artificial brooding and weak chick rearing of Baer's Pochard, including a staged net cage 100 and a stepped swimming pool 200. The staged net cage 100 is divided into a first-stage rearing net cage 110 and a second-stage rearing net cage 120. The first-stage rearing net cage 110 is used to raise Baer's Pochard chicks aged 4 to 10 days, and the second-stage rearing net cage 120 is used to raise Baer's Pochard chicks aged 11 to 30 days. The first-stage rearing net cage 110 and the second-stage rearing net cage 120 are respectively equipped with inner cages for protecting weak chicks.

[0164] Specifically, the stepped swimming pool 200 includes a first stepped swimming pool 210, a second stepped swimming pool 220, and a third stepped swimming pool 230; the first stepped swimming pool 210, the second stepped swimming pool 220, and the third stepped swimming pool 230 are arranged in a stepped manner from low to high and are adjacent to each other, which is used to transition the water pressure of the swimming pool in a stepped manner to train the jumping and diving strength of young birds.
