Description

Technical Field

[0001] The invention relates to the technical field of breeding baer's pochard, and in particular to a method and system for artificial brooding and weak chick conservation of baer's pochard. Background Art

[0002] The Baer's Pochard is an extremely endangered species. The mortality rate of Baer's Pochard chicks is as high as 72.7% within one month of age. The main reasons include hypothermia, malnutrition, stress response and predation by natural enemies. The existing insulation technology mainly follows the standards of other water birds and fails to adapt to the special needs of Baer's Pochard, resulting in damage to its digestion, development and immune system, and failing to survive the high-risk mortality period of one month.

[0003] In addition, fighting and trampling accidents frequently occur among young Baer's Pochard during mixed-breeding, and they are easily injured, with the main injured parts including the head, beak, wings and feet. The mixed-breeding 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. The probability of death due to stress among young Baer's Pochard is higher than that of other young water birds.

[0004] One of the species specificities of the Baer's Pochard is that it is extremely sensitive. The Baer's Pochard is smaller in size and more easily stressed, resulting in more screaming and aimless running around. It is a high-stress species. In the past, the cages were too large, making it difficult to catch the Baer's Pochard. The capture process was prone to collisions, affecting later reproduction. In addition, traditional cement floors cause the Baer's Pochard chicks to have hyperplasia of their foot pads and growth of papillae. Improper swimming time and method also lead to unbalanced muscle and wing development.

[0005] Overall, improving the survival rate, healthy development and group socialization ability of the blue-headed duck is crucial for population conservation, expansion and reintroduction into the wild. At present, domestic technical regulations for the breeding and management of wild birds mainly involve more common waterfowl such as mallards and spot-billed ducks, and there is no breeding technology for rare and endangered species of diving ducks.

[0006] Therefore, there is an urgent need for a method and system for artificial rearing and weak chick care of Baer's Pochard to overcome the problems of high deformity rate of Baer's Pochard chicks, easy injury during mixed breeding, unhealthy development, inability of weak chicks to eat independently, and high mortality rate due to their thinness and weakness. Summary of the invention

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

[0067] 4. Strengthen behavioral training through stepped swimming pools, create multi-level swimming depths, support the transition training of young blue-headed ducks from shallow water to deep water, enhance the development of their muscles and preen glands, and reasonably arrange sunbathing and exercise time to effectively promote vitamin D synthesis and reduce stress.

[0068] 5. A feeding and care program specially designed for weak chicks ensures that they can effectively integrate into the group, improve developmental gaps, enhance overall community stability, improve food competition and reproductive potential, and provide a solid foundation for subsequent population expansion and reintroduction to the wild.

[0092] The embodiment of the present invention provides a method for artificial breeding and weak chick conservation of Baer's Pochard. Through 5 years of monitoring and data collection, improvements are made to the situation where the mortality rate of Baer's Pochard chicks within one month of age is as high as 72.7%. Within one month of age, the chicks will go through key stages such as yolk absorption, body temperature system development, body mass index growth and post-mature molting; each stage faces different survival challenges. The present invention organically combines these key development nodes to achieve a reasonable transition.

[0093] Figure 1 A schematic diagram of the method flow for artificial brooding and weak chick conservation of Baer's Pochard provided in an embodiment of the present disclosure.

[0094] like Figure 2 As shown, during the first nursery stage, temperature preservation and weight monitoring were carried out on 1- to 3-day-old Baer's Pochard chicks.

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

[0096] like Figure 1 , Figure 2 And refer to Fig.15 and Fig.16 As shown, 1-3 day old blue-headed duck chicks are placed in an incubator, the placement time is adjusted to 2-6 hours, and the blue-headed duck chicks are placed in an incubator after their down feathers are completely dry. The temperature in the incubator is adjusted to 36-35°C, and the set temperature is lowered by 0.5-1°C every day; the blue-headed duck chicks are placed in the incubator for 12 hours and then drink boiled warm water, and the water temperature is adjusted to 36-37°C; the blue-headed duck chicks are placed in the incubator for 24 hours and then fed with pellets, and the feed amount is set to 2-3g / chick, and the preferred feed amount is 2g / chick; the weight of the blue-headed duck chicks is monitored and the health status is tracked when they are not eating, and a weight curve of the chicks is drawn.

[0097] Specifically, when the blue-headed duck is 1 to 3 days old, it mainly absorbs the yolk sac, and the chicks are in a "pseudo-alive" state. If they stay in the incubator for too long, the fan will cause a lot of down feather loss. Therefore, the incubator placement time is adjusted to 2 to 6 hours to reduce the shedding of down feathers. Too fast absorption of the yolk sac will cause weight loss, which is not conducive to weight recovery. Therefore, the insulation strategy is adjusted. After the down feathers of the blue-headed duck chicks are completely dry, they are placed in an incubator. The temperature in the incubator is adjusted to 36 to 35°C, and the temperature is lowered by 0.5 to 1°C every day to avoid excessive consumption of the yolk sac. The blue-headed duck chicks are placed in the incubator for 11 to 13 hours and then given boiling warm water to drink. The water temperature is adjusted to 36 to 37 ℃, protect the stomach and intestines, and facilitate nutrient absorption. The young blue-headed duck chicks are fed pellets after being placed in the incubator for 20 to 36 hours, and the feed amount is set at 2 to 3 g / bird. Preferably, according to the meconium excretion situation, it can be fed earlier if the meconium is excreted, and later if it is not excreted. Water cannot be lacking in the process. Preferably, the pellets are selected from Zhengda 520 or 521 pellets, which are beneficial to the nutrient absorption and weight gain of the blue-headed duck. The weight curve of the chicks is drawn to pay attention to the chicks with faster weight loss. Good and stable insulation measures are the key to the safety of young birds through the high-risk death period of 1 month old, which promotes their growth and development, reduces energy consumption, reduces the stress response caused by low temperature, and improves immunity.

[0098] like Figure 1 Combined with Figures 3 to 14 As shown, in the second nursery stage, the environmental temperature is adjusted for the 4-10-day-old Baer's Pochard chicks, the first environmental temperature is lowered to the second environmental temperature, and the Baer's Pochard chicks are kept warm and nurtured;

[0099] The 4- to 10-day-old young blue-headed ducks are fed with a quantitative feeding method to provide nutrition.

[0100] Develop a health assessment system for 4- to 10-day-old Baer's Pochard chicks;

[0101] For 4-10 day old young blue-headed ducks, a staged net cage 100 and a stepped swimming pool 200 are set up, and the first stage functional training is carried out based on the first stage breeding net cage 110, the first stepped swimming pool 210 and the second stepped swimming pool 220.

[0102] In an embodiment of the present invention, the environmental temperature of the blue-headed duck chicks is adjusted based on the incubator in the second incubation stage, and the first environmental temperature is set to 35-34°C. For healthy blue-headed duck chicks, the first environmental temperature is cooled to a second environmental temperature of 29-28°C within 7-10 days of age. For weak blue-headed duck chicks, the cooling is slowed down and the first environmental temperature is cooled to a second environmental temperature of 29-28°C.

[0103] Specifically, young Baer's Pochards have poor thermoregulation ability during the down feather period and are more likely to show low temperatures in their beaks and paws. Therefore, the ambient temperature should be gradually lowered from 35-34°C to around 29-28°C. Healthy chicks should complete this at around 7-10 days of age, and weak chicks should complete this at 10-15 days of age. Steady warmth measures can reduce animal stress and reduce diarrhea, chills, and even early death caused by hypothermia.

[0104] In an embodiment of the present invention, in the second nursery stage, a quantitative feeding method is adopted for 4-10 day old blue-headed duck chicks to provide nutrition, including the quantitative feeding of the 4-10 day old blue-headed duck chicks, drinking boiled warm water, and adding nutrients; the quantitative feeding method includes quantitative feeding of pellets and mealworms, the average daily feeding number is 5-6 times, the feeding interval is 2-3 hours, and the 3-day old blue-headed duck chicks are fed, the initial feed amount of each is set to 4-5g, preferably 3.8g, and the ending feed amount at the last feeding of the day is set to 1.5-2 times of the previous time. The 3-day old blue-headed duck chicks are fed 3 mealworms each time, and 3 mealworms are added per meal for each additional day of the blue-headed duck chicks.

[0105] Specifically, 4-10-day-old blue-headed duck chicks are more likely to suffer from tendon slippage and diarrhea, and weak chicks begin to show slow weight gain or even weight loss, so it is necessary to adjust the nutritional supply and formulate a special maintenance plan. The nutritional supply adopts quantitative feeding of granular feed 520 / 521 and mealworms, an average of 5 to 6 times a day, with an interval of 2 to 3 hours between each feeding; the average feed amount for 3-day-old blue-headed duck chicks is 3.8g / time / bird, and the remaining feed is recovered and weighed each time. The next feeding should be reduced as appropriate. If there is no surplus, the next feeding should be increased as appropriate. The last feed amount of the day is 1.5 to 2 times the previous feed, and the specific amount is adjusted according to whether there is surplus on the next day; 3-day-old blue-headed duck chicks should be fed 3 mealworms / time / bird, and 1 to 2 extra for weak chicks. 3 are added per meal for each young bird every day, and the amount should be increased or decreased as appropriate according to the feces situation to ensure that the drinking water for the chicks during this period is warm and cool after boiling. Nutrients are added, preferably poultry multivitamins and poultry cod liver oil.

[0106] It should be noted that the present invention describes the feeding tools and methods. The feed holding tools for 4-10 day old chicks should not be too large, and each chick should have a dining place. The inside of the container should be avoided to avoid slippage when the chicks compete for food. The waterer for 3-10 day old chicks should be a small poultry waterer to avoid the chicks' abdomen getting wet and catching a cold or the umbilical cord of weak chicks getting infected.

[0107] The present invention also provides another feeding method, which focuses on the weight and nutrition of weak chicks in this period, integrates them into the group, and shortens the development gap. If the weak chicks cannot eat independently, 4 to 5 granular materials can be soaked in warm water, mashed with 2 to 3 mealworms into a paste, put into a 2 to 2.5 ml syringe (without the needle), pushed out about 2 mm, and gently touch the lower edge of the beak of the weak chicks to stimulate them to open their mouths and put them in to supplement nutrition; after the weak chicks can eat independently, if they have poor competitive food ability, the cage-in-cage weak chick conservation method is used to ensure that they can eat and exchange information with the group.

[0108] In an embodiment of the present invention, the health assessment system for 4-10 day old Baer's Pochard chicks in the second conservation stage includes the first weight monitoring, feces collection, behavioral observation and morphological development of the 4-10 day old Baer's Pochard chicks to establish a health assessment system.

[0109] Specifically, when conducting weight testing, the weight curve of one-month-old Baer's Pochard chicks will follow a logistic "S" curve, and will experience weight loss, steady growth and rapid growth periods; the average weight of 4-10-day-old Baer's Pochard chicks will steadily increase from 25g at birth to 60g. If the weight of the chicks drops significantly, special attention should be paid and timely measures should be taken.

[0110] Furthermore, feces collection and testing showed that young blue-headed ducks excrete dark green meconium at 1 to 2 days old, and young blue-headed ducks begin to eat granular feed at 4 to 10 days old. Healthy feces should be yellow, formed, dry and odorless. If brown, brown, watery, mucous or smelly, it should be tested as soon as possible and treatment should be taken.

[0111] Further behavioral observations were conducted. 4 to 10 days of age is the earliest and best period to distinguish between healthy and weak chicks. Healthy chicks are lively and strong, feed themselves, have warm feet, bright eyes, a clear sense of direction, and can quickly capture moving objects. Weak chicks are slow to react, not active in feeding, stand unsteadily, have low foot temperature, poor sense of direction, and low photosensitivity. There are fewer types of behaviors in 4-10 day old young birds, mainly collective exploratory behaviors, feeding behaviors, and drinking behaviors, and they rarely become isolated from the group. If they become listless and lie down for a long time, extra attention should be paid.

[0112] Furthermore, in terms of morphological development, due to its biological characteristics such as being good at diving and molting after juveniles, the Baer's Pochard has a shorter morphology, thicker and shorter tarsus, and larger and thicker webbed feet. Therefore, during the 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] Next, the first stage functional training in the second conservation stage is described, including modular phased design, precise management design, environmental adjustment, and safety protection design of the first stage breeding cage 110;

[0114] Based on the observation and monitoring of the first stage feeding net cage 110, the companionship mode of the companion animal is adjusted to companionship outside the cage;

[0115] Based on the first stage of rearing net cage 110, a cage-in-cage weak chick care method is carried out;

[0116] Sunbathing of 4-5-day-old Baer's Pochard chicks to promote synchronous development of body functions;

[0117] The first stage feeding net cage 110 is set as a 4-10 day old net cage, and 4-10 day old Baer's Pochard chicks are fed in groups of 5-10.

[0118] In the embodiment of the present invention, two modularized staged cages are designed, namely the first stage breeding cage 110 for 4 to 10 days of age and the second stage breeding cage 120 for 10 to 30 days of age. The following is a specific implementation of the 4 to 10 day stage cage.

[0119] Specifically, the young blue-headed ducks are raised in groups of 5 to 10, and the net cages are set with two grids of length, width and height ratios of 3*2*2 (105*70*70cm) and 2*2*2 (70*70*70cm). This solves the problem that the young birds at this stage are very small and have less down feathers, so they are easy to get into corners. The young birds tend to cluster for warmth in the early stages. If the animals scatter, the stray individuals may suffer from hypothermia and die. It also reduces the stress of the young birds. By reducing the appropriate space, the problem of strong collision force and high deformity rate after the young birds' run-up is reduced.

[0120] Furthermore, in order to facilitate nursing staff to observe the behavior and health status of chicks in real time and realize precise management, and to make the distance between the cage doors just suitable for safe and no-dead-angle operation of the human upper limbs, a module of animal access door is designed on the bottom layer of the cage for the chicks to enter and exit freely, so as to reduce the interference and accidental injuries caused by human capture by hand, and strengthen animal behavior training. At the same time, a module of manual operation door is opened in the diagonal direction of the upper layer, which is used for collecting feces, placing food and water, and assisting animal behavior training. The animal access door and the manual operation door have different functions, which are beneficial to reduce the stress rate of chicks, stimulate natural behavior, and health care.

[0121] It should be noted that in the present invention, a horizontal barrier (35cm*35cm) is set in the staged net cage 100 to place incandescent lamps (which only emit light but not heat), baking lamps (which heat and emit light) or night lights (which only emit heat but not light) as the main way of built-in microenvironment control to prevent falling and hurting the young chicks; in case of extremely hot and humid weather, air circulation facilities can also be installed here to create a more stable microclimate and reduce the stress caused by changes in the external environment.

[0122] For example, in the present invention, the staged net cage 100 uses two soft materials to cover the edges and bottom of the cage, which are laid on the ground below the net cage to reduce the risk of collision and pinching and protect the feet of young chicks; one is a 3.5mm thick, S-patterned hollow PVC cushion, and the other is a 1.5mm thick, latex non-slip convex PVC cushion; the present invention prefers the first cushion for safety protection, and the mesh aperture design of the staged net cage 100 in the present invention is moderate to prevent the escape of young birds and the invasion of foreign predators.

[0123] Furthermore, monitoring equipment at the right angle of the upper layer of the staged net cage 100 helps caregivers to observe the behavior and health status of the chicks in real time and achieve precise management. It can adjust the companionship mode of other ducks and birds to companionship outside the cage, and use safety fences to prevent their escape. It can promote the active feeding and warming of the young blue-headed ducks, and group interaction provides psychological needs and avoids interspecies conflicts.

[0124] Specifically, the present invention provides a cage-in-cage weak chick conservation method, which provides weak chicks with protection and a safe space to avoid being separated from the group, allows them to maintain information exchange with the main cage group, and promotes psychological stability. An inner cage composed of a single-piece grid with a length, width and height ratio of 1*1*1 is set in the stage-type net cage 100, and an entrance is left on one side. The inner cage can be flexibly placed in cages of different stages, and its field of vision is not restricted. It is used to protect weak chicks and injured individuals in the group, and is convenient for individual feeding and treatment. The inner cage can be placed in the middle of the net cages of different stages, not attached to the wall, which is convenient for ducks to gather and for group information exchange. The cage structure can also be adjusted regularly to adapt to the space and social needs of different stages to ensure reasonable care for weak chicks and healthy chicks.

[0125] More specifically, adjust the time and method of exercise in the cage, advance the time for young birds to receive sunbathing to 3 to 5 days of age to promote the synchronous development of various body functions. The minimum outdoor ground and air temperature is 28 to 29°C. The activity area for young chicks should avoid direct sunlight and need to be shaded by trees or form a light spot environment.

[0126] The specific data is that the sunbathing time for young blue-headed duck chicks in North China should be between 9:00-10:00 in the morning and 15:00-17:00 in the afternoon. The specific time and duration need to be adjusted according to the latitude, season and climate of the breeding site. This measure is beneficial to the synthesis of vitamin D, regulation of the body temperature system and reduction of stress rate of young blue-headed duck chicks.

[0127] As shown Fig.11 Shown is a schematic diagram of the use display structure of the stepped swimming pool in the present invention.

[0128] Next, the first stage of functional training in the second nursing stage is described, which also includes the first water test of 5-day-old Baer's Pochard chicks based on the first step swimming pool 210;

[0129] Based on the second-tier swimming pool 220, 10-day-old young Baer's Pochard were tested for 5 to 10 days;

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

[0131] Tap water exposed to the sun is used in the first step swimming pool 210, and natural lake water is added in the second step swimming pool 220.

[0132] Specifically, the stepped swimming pool 200 adopts a multi-stage step design, and each step provides a different water depth, which is used for the young blue-headed duck chicks to gradually adapt to the water depth, especially the transition from shallow water to deep water, promoting the development of the preen glands, wing muscles, legs and feet of the chicks, so that they develop synchronously.

[0133] The specific experimental data are as follows:

[0134] The legs of a 5-day-old red-headed duck chick are 5 to 6 cm long and can jump 2 to 3 cm high. For this purpose, the first-step swimming pool 210 is designed to have a length, width and height of 120*80*8 cm and a water level difference of 2 to 3 cm. This area is suitable for 5 to 10 chicks to test the water for the first time, and a water depth of 5 to 6 cm is suitable for 5-day-old chicks to test the water; the second-step swimming pool 220 has a length, width and height of 120*100*18 cm and a water level difference of 3 cm. This area is suitable for 5 to 10 chicks to jump into the pool independently after they have advanced in swimming, and a water depth of 15 cm is suitable for 10-day-old chicks to test the water for 5 to 10 days; the third-step swimming pool 230 has a length, width and height of 120*100*30 cm and a water level difference of 3 to 5 cm. This area is suitable for 5 to 10 chicks to jump into the pool independently after they have advanced in swimming, and a water depth of 25 to 27 cm is suitable for 15 to 20-day-old chicks to test the water for 10 to 15 days. The stepped swimming pool 200 provides different water depths in three corresponding stages. After the young blue-headed ducks gradually adapt to the water depth, they can flexibly choose, including the transition from shallow water to deep water and the free choice from deep water area to shallow water area.

[0135] It should be noted that the present invention has designed a safety protection for the stepped swimming pool 200, adding anti-skid plates and soft cushions to prevent the chicks from slipping or falling accidentally. The first stepped swimming pool 210 needs to be installed with three steps with an angle of less than 30°. The chicks tend to enter the water through the steps, and like to rest and preen on the steps. The steps can be independent steps or fixed steps, or preferably, independent steps that can be freely placed and moved. The stepped swimming pool 200 needs to be installed with a movable anti-skid plate (with a soft cushion on top, the same specifications as the cage cushion). The preferred parameter setting is that the size of the first stepped swimming pool 210 is 120cm*8cm, and the size of the second and third stepped swimming pools is 120*15cm. The wide edge of the anti-skid plate should buckle the edge of the pool for easy disassembly and movement. The application of the anti-skid plate is closely related to the ecological habits of young chicks. After swimming, young blue-headed duck chicks need to flap their wings many times and repeatedly to promote muscle growth, and to preen their feathers and rest to restore body temperature and strength, and stimulate the preen glands to secrete oil. The anti-skid plate is a key design for young chicks' swimming training.

[0136] Specifically, intelligent water level sensing is added, and low water level sensors are set for identification and alarm. Preferably, automatic water reservoirs and automatic water fillers can be set in the pool, and water purification devices can be set to filter, drain, disinfect and clean the water in the stepped swimming pool 200 to support the healthy growth of young chicks. Excretion holes are set in the staged pool, and feces are uniformly fermented after discharge and used as fertilizer.

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

[0138] The present invention provides swimming training control data for young blue-headed ducks as follows:

[0139] The stepped swimming pool is designed according to the biological development of the young blue-headed duck. The stepped transition of swimming water pressure can train the jumping and diving intensity of the young birds and avoid stress and hypothermia. The swimming time and frequency of the young birds are regulated by the stepped swimming pool 200. The young birds aged 5 to 10 days swim twice a day, and the first swimming time is 5 minutes. The frequency is gradually increased according to the performance of the young birds. If the back feathers of the young birds are dry after entering the water, 5 minutes can be added on the second day. If the back feathers of the young birds are exposed to the skin, or the young birds jump out of the pool quickly, the time will not be increased, and so on. After 10 days of age, the back feathers of healthy chicks are basically no longer wet after entering the water. They swim 2 to 3 times a day, each time for 40 minutes to 1 hour. The weak chicks should be adjusted according to their status, and the appropriate time is 20 to 30 minutes. After 20 days of age, the gap between weak and healthy chicks becomes smaller, and they swim 3 times a day. Each time lasts 50 minutes to 1 hour. There is no limit on the swimming time and frequency of chicks after 30 days of age, but the positive sunlight period, i.e. 12:00 to 14:00, should be avoided. The suitable swimming time period is between 9:00 and 11:00 and 15:00 and 17:00. The first-step swimming pool 210 should be used after being exposed to the sun with tap water. After the chicks enter the second-step swimming pool 220, 200-500 ml of water from natural lakes or water bodies should be added every day on the basis of tap water to gradually adapt them to the water environment in the wild to avoid stress when they are released into the wild. After the chicks enter the third-step swimming pool 230, it should be ensured that there is 1 / 3-1 / 2 natural water in the pool, and there should be a water purifier to filter it. Note that the water temperature should be kept at around 30-35°C. After each water change, the water should be exposed to the sun before use.

[0140] Next, the third nursery stage is described, which includes the second weight monitoring, feces collection, behavioral observation and health status assessment of morphological development of 10-30-day-old Baer's Pochard chicks in health monitoring;

[0141] Nutritional adjustments are made to the young blue-headed ducks, including:

[0142] Feed 10-15 day old young Baer's Pochards with vegetables, provide them with vegetable leaves and process them into minced meat;

[0143] Adjust the feeding amount, feed soft feed, mealworms, and pellet feed. The soft feed is a mixture of pellet feed, chopped vegetables, and chopped eggs.

[0144] Drinking water is adjusted for young Baer's Pochard, and the drinking water adjustment includes:

[0145] Add tap water that has been exposed to the sun to boiling warm water, with the first adding ratio being 5:1 to 3:1, preferably 4:1, for 5-10 day old young blue-headed ducks;

[0146] 10-15-day-old Baer's Pochard chicks drink tap water that has been exposed to the sun directly;

[0147] The young blue-headed ducks aged 15 to 30 days drink the water of the third stepped swimming pool 230 mixed with the water of the natural lake.

[0148] Specifically, during weight monitoring, the average weight of 11-30-day-old Baer's Pochard chicks will increase from 60g to 270g, entering a period of rapid growth and development. At this time, if the chicks lose weight for more than two consecutive days, it is the primary signal that there is a problem with the health of the chicks and should be given special attention.

[0149] Specifically, when collecting feces, 11 to 30-day-old blue-headed duck chicks begin to add a small amount of spinach, lettuce, carrots, water plants and other supplementary food. Healthy feces should be yellow-green, formed, dry and odorless. If brown, brown, watery, mucous or smelly, it should be tested as soon as possible and treatment should be taken.

[0150] Specifically, in behavioral observations, the types of behaviors of young birds aged 11 to 30 days increased, including basic behaviors such as preening, swimming, diving, feeding, resting, and social behaviors such as playing, competing for food, and hiding. There will be mutual learning and information exchange among groups. If there is any phenomenon of isolation or dull behavior, the cause should be found in time.

[0151] Specifically, at the end of morphological development, young birds at the age of 11 to 30 days have completed most of their post-juvenile molt, with the tertiary flight feathers transitioning to secondary flight feathers, and there is still a small amount of down on the chest and back feathers. If there are individuals with delayed molting, the nutritional feeding of the individual should be adjusted in time. Because young birds at the age of 11 to 30 days grow rapidly, the pressure of weight on the feet increases sharply. Therefore, this period is a high incidence period of foot pad hyperplasia in young birds, and special attention should be paid to the balance of weight and muscle development and activity level.

[0152] In the embodiment of the present invention, specific steps are provided for the nutritional adjustment of young chicks aged 11 to 30 days. Young chicks are fed vegetables from 10 to 15 days old. To avoid throat choking, leafy vegetables (rapeseed and lettuce) should be provided as much as possible and processed into minced food. The amount of food should be increased gradually from small amounts to large amounts. The feeding amount during this period should be adjusted, that is, generally, a sufficient amount of soft food (granular food + vegetable minced food + egg minced food) is fed for the first meal; a small amount of soft food is fed for the second meal; and vegetable minced food + mealworms are fed for the third meal, and the mealworms are adjusted to 5 to 6 pieces / day every other day. For the fourth meal, feed enough Zhengda pellets; for the last meal, provide 10 mealworms (about 50g) to each chick; Drinking water adjustment: after the chicks are 5-10 days old (starting from 5 days old for healthy chicks and 10 days old for weak chicks), add tap water that has been exposed to the sun to the boiled water each time, with the first ratio of 4:1. After 10-15 days of age, they can drink all tap water that has been exposed to the sun. After 15-30 days of age, the animals can drink water from the swimming pool mixed with natural lake water (synchronized with the stepped swimming pool 200).

[0153] Next, the third conservation stage also includes the second stage of functional training for the young blue-headed duck chicks. The second stage of functional training includes:

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

[0155] Based on the observation and monitoring of the second stage feeding net cage 120, the companion animal companionship mode is adjusted to companionship outside the cage;

[0156] Based on the second stage of rearing net cage 120, a cage-in-cage weak chick care method is carried out;

[0157] Conduct daytime swimming behavior training on 11- to 30-day-old Baer's Pochard chicks;

[0158] The second stage feeding net cage 120 is set as an 11-30 day old net cage, and the 11-30 day old Baer's Pochard chicks are fed in groups of 5-6;

[0159] Perform swimming training based on the third stepped swimming pool 230, and transition from the second stepped swimming pool 220 to the third stepped swimming pool 230;

[0160] Natural lake water is added to the third step swimming pool 230, and filtered in a water purification box to make the water ratio in the third step swimming pool 230 be 1:3-1:2, and the water temperature be 30-35°C.

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

[0162] More specifically, the 11-30 day old chicks have gradually adapted to the second-step swimming pool 220, and the healthy chicks are transitioning to the third-step swimming pool 230. It should be noted that the swimming needs of weak chicks and healthy chicks are different, and the duration should be adjusted. Game training should be designed according to the unique developmental requirements of the young blue-headed ducks to avoid stress, tendon slippage, wing loss, developmental delay, etc. in the chicks, reducing the impact on subsequent survival abilities such as flying and escaping, and 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 conservation of blue-headed ducks, including a staged net cage 100 and a stepped swimming pool 200. The staged net cage 100 is divided into a first-stage feeding net cage 110 and a second-stage feeding net cage 120. The first-stage feeding net cage 110 is used to feed blue-headed duck chicks aged 4 to 10 days, and the second-stage feeding net cage 120 is used to feed blue-headed duck chicks aged 11 to 30 days. The first-stage feeding net cage 110 and the second-stage feeding net cage 120 are respectively provided 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 adjacently arranged from low to high in a stepped manner, and are used to transition the water pressure of the swimming pool in a stepped manner to train the jumping and diving intensity of young birds.
