Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of breeding, in particular to an artificial breeding method of Phoenicopterus chrysos. BACKGROUND

[0002] Phoenicopterus chrysos is one of the birds with the most red body color in the world, and has high ornamental value and ecological protection significance. Due to factors such as destruction of the original habitat and human disturbance, the number of wild populations has been declining, and it has become a rare bird in urgent need of protection.

[0003] Artificial breeding is a key means to supplement the population of Phoenicopterus chrysos and maintain the continuation of the species, but the biological characteristics of the species have brought many technical problems to artificial breeding. The existing breeding methods have significant deficiencies in fertilization rate, hatching rate and survival rate of nestlings. The specific problems are as follows: the formula of the adult bird feed is not optimized, some feed formulas do not fully combine the feeding preference and nutritional needs of Phoenicopterus chrysos, resulting in poor adult bird condition, which in turn restricts the improvement of fertilization rate and makes it difficult to maintain a high fertilization level; the unreasonable calcium content in the feed will cause imbalance in gas exchange and water regulation required for embryo development, eventually causing embryo death or failure to break the shell, in addition, the imbalance of nutrients in the feed will also lead to insufficient fertility of fertilized eggs, even if the incubation conditions are met, the embryo may stop growing in the later stage of development, and eventually fail to break the shell; Phoenicopterus chrysos is a highly neurotic species, and the development process of young birds has obvious stage characteristics. The lack of feed adaptability, stress response prevention and control, and inaccurate feeding management and disease control result in difficulty in guaranteeing the survival rate of nestlings.

[0004] In summary, the existing artificial breeding method of Phoenicopterus chrysos still has deficiencies in feed formula optimization, precise control of incubation parameters, stress prevention and control of young birds, and disease treatment, which leads to difficulty in simultaneous improvement of fertilization rate, hatching rate and survival rate of nestlings, and it is urgent to establish a systematic and precise artificial breeding technology system to solve the above key technical problems. SUMMARY

[0010] More preferably, the artificial brooding feed includes: feed for 1-9 day old chicks, comprising the following ingredients by weight: 30-35 parts live loach, 2.5-3.5 parts egg yolk, and 12-15 parts water; feed for 10-20 day old chicks, comprising the following ingredients by weight: 20-25 parts live loach, 10-13 parts shrimp, 2.5-3.5 parts egg yolk, and 12-15 parts water; after 21 days of age: in addition to the feed for 10-20 day old chicks, live mealworms are provided for independent feeding, gradually transitioning to adult bird feed.

[0011] More preferably, the feeding frequency includes: 5-7 meals per day for 1-7 days old, 4-6 meals per day for 8-14 days old, 3-5 meals per day after reaching 200g in weight, and 2-3 meals per day after learning to feed independently; before learning to feed independently, the amount of food fed per meal should not exceed 10% of the body weight, and the daily weight gain should be controlled at 10%-15%; after learning to feed independently, the amount of food fed and the weight gain are determined by the young bird's appetite.

[0012] Preferably, the method for preparing the feed includes: weighing the corresponding raw materials according to the age, mixing them into a paste, and freezing them at -18~-22℃ for 45h-50h; before consumption, thawing them at 2-5℃ and then warming them to 38-40℃ with boiling water.

[0013] Preferably, the artificially raised chicks feed is supplemented with the following additives before feeding: vitamin B1, vitamin B2, vitamin B6, vitamin B12, B complex vitamins, vitamin C, multi-enzyme tablets, water-soluble calcium, probiotics, vitamin AD and electrolyte multivitamins.

[0014] Preferably, the artificial brooding includes: 1-14 days old: setting the initial temperature of the brooding box at 37-38℃, decreasing it by 0.3-0.7℃ daily; after 15 days old: gradually removing the chicks from the brooding box and transferring them to a metal cage at time gradients of 0.5-1.5h, 5-7h, 10-15h, and 20-28h daily; after the chicks start feeding on live mealworms independently: removing them from the metal cage at gradients of 0.5-1.5h, 5-7h, 10-15h, and 20-28h daily, and transferring them to a large outdoor rearing cage; after 3 months old: transferring them to the exhibition area for rearing.

[0016] Compared with the prior art, the present invention has the following beneficial effects: This invention addresses the problems of low fertilization rate, hatching rate, and chick survival rate in existing artificial breeding techniques for the scarlet ibis, and provides an artificial breeding method for the scarlet ibis: In the adult bird rearing stage, the problem of insufficient targeting and nutritional imbalance of existing feed formulas is solved by scientifically proportioning diversified raw materials and dynamically regulating nutrition. Shrimp shells are added to the feed before breeding to ensure the reproductive performance of adult birds. During the breeding period, the shrimp shells in the feed are dynamically adjusted to avoid the eggshells being too thin or too thick, which would affect the hatching rate and the survival rate of chicks.

[0017] The artificial incubation process strictly controls the water loss rate to 14wt%-16wt%. By combining precise parameters of temperature, humidity, egg turning, and egg drying, it solves the problems of insufficient water loss in thick-shelled eggs and excessive water loss in thin-shelled eggs. It effectively avoids hatching defects such as yolk sac abnormalities and heart bleeding, and significantly improves the hatching rate and healthy chick rate compared to existing technologies.

[0018] The artificial brooding process employs age-segmented feed formulations and a gradient environmental adaptation method, tailored to the digestive capabilities and stress characteristics of chicks at different stages. Specialized additives alleviate stress responses and prevent digestive and nutritional problems, while the gradient transition feeding model reduces the stress risk from sudden environmental changes. Combined with disease control methods, this improves chick survival rates and solves the brooding challenges of the scarlet ibis, a highly neurotic species, providing systematic and efficient technical support for the conservation of this rare species.

Detailed Implementation

[0020] This invention provides a method for the artificial breeding of scarlet ibises, including: raising adult birds, fertilization, artificial incubation, and artificial brooding; the feed for raising adult birds and fertilization includes the following ingredients in parts by weight: 32-38 parts beef, 8-12 parts egg yolk, 8-12 parts cornbread, 32-38 parts cooked carrots, 32-38 parts tomatoes, 8-12 parts apples, 18-23 parts watermelon, 28-32 parts crucian carp, 18-23 parts shrimp, and 55-65 parts loach.

[0021] In this invention, the feed preferably includes dried shrimp. During the breeding and fertilization period, the amount of dried shrimp in the feed is dynamically adjusted according to the water loss of the bird eggs: After collecting the bird eggs, artificial incubation is carried out. The humidity of the incubator is adjusted according to the optimal daily water loss (optimal daily water loss (g) = 0.0074 × initial egg weight - 0.0086) until the optimal daily water loss is reached. If the daily water loss is still lower than the optimal daily water loss after adjusting the humidity of the incubator within 5 days, it indicates that the shell of the bird egg is thick and does not easily lose water, so the dried shrimp in the feed is removed; if the daily water loss is still higher than the optimal daily water loss after adjusting the humidity of the incubator within 5 days, it indicates that the shell of the bird egg is thin and easily loses water, so 1.5-2.5 parts by weight of dried shrimp are added to the feed.

[0022] If the eggshell of the scarlet ibis is too thick, moisture cannot dissipate easily, leading to obstructed gas exchange and water imbalance necessary for embryonic development. This can easily cause yolk sac abnormalities, poor umbilical cord development, and ultimately embryonic death or failure to hatch. Conversely, if the eggshell is too thin, moisture loss is too rapid, causing embryonic dehydration, which can also lead to developmental arrest, difficulty hatching, or weak chicks. This invention dynamically controls the eggshell thickness of the scarlet ibis by adjusting the amount of dried shrimp in the feed according to daily water loss, ensuring a balance of water and gas exchange within the egg during incubation, and improving hatching rate and chick survival rate.

[0023] This invention precisely meets the nutritional needs of adult scarlet ibises during their growth and breeding seasons through a scientifically proportioned blend of diverse ingredients: beef, crucian carp, shrimp, and loach provide high-quality animal protein and essential amino acids, ensuring robust health; cooked carrots and tomatoes are rich in beta-carotene, while apples and watermelons supplement vitamins and water, working together to maintain bright feathers and metabolic balance; steamed buns provide carbohydrates as an energy source, while egg yolks fortify lecithin and trace elements. During the breeding and fertilization period, the amount of shrimp shells can be dynamically adjusted in daily feeding based on the quality of the eggshells laid by the adult birds, ensuring that the eggshells are of moderate thickness, thus optimizing gas exchange and water regulation for embryonic development. Precisely defining the weight ratio of each ingredient matches the dietary preferences of scarlet ibises and achieves a balanced supply of protein, vitamins, and minerals, solving the problem of poor health and fluctuating fertilization rates in adult birds caused by nutritional imbalances in existing formulas.

[0024] In this invention, the preferred method of breeding and fertilization includes: monitoring the physical characteristics of adult scarlet ibises; when the beak of an adult bird changes from red to black, it is determined that it has entered the breeding and pairing period; continuously observing the behavior of adult birds; when both male and female individuals repeatedly exhibit mating behavior, it is determined that the pairing is successful; after successful pairing, the adult birds' rearing environment is kept quiet to avoid external interference affecting their breeding behavior; successfully paired scarlet ibises will begin nest building, and mating may continue during the nest building process; suitable nesting materials such as mulberry trees are provided, while maintaining a stable environment in the exhibition area to meet the nest building needs; when paired adult birds exhibit continuous nest-sitting behavior, it indicates that they are about to start laying eggs; the monitoring frequency is increased, and the start time and number of eggs laid are recorded; taking advantage of the scarlet ibises' habit of nest building and egg laying in groups, after all adult birds have completed one round of egg laying, the eggs are collected uniformly to avoid the problem of individual adult birds that lay eggs late stopping egg laying due to scattered egg collection; the handling of eggs should be gentle to avoid damaging the eggshells; after collection, the birds are immediately transferred to the artificial incubation stage.

[0025] This invention solves the problem of ambiguous determination of the breeding season of the American scarlet ibis by monitoring both appearance characteristics and behavioral performance, and achieves accurate identification of key links such as pairing and egg laying. By adopting a method of collecting eggs in a group after egg laying, it avoids interfering with the egg laying of individual adult birds that lay eggs later, and can maximize the egg laying of paired adult birds, thus providing a prerequisite for improving the breeding success rate.

[0026] In this invention, the artificial incubation process preferably controls the water loss rate of bird eggs to 14wt%-16wt%, more preferably 15wt%; the artificial incubation method preferably includes: setting the temperature to 37-38℃ and the initial humidity to 48%-52%; dynamically adjusting the humidity of the incubator according to the optimal daily water loss (optimal daily water loss (g) = 0.0074 × initial egg weight - 0.0086); turning the eggs once every 1.5-2.5 hours, turning them 80°-100° each time, and airing the eggs for 3-5 minutes each day; after the eggs hatch, adjusting the humidity to 68%-72% and stopping the turning and airing of the eggs; more preferably, it includes: setting the temperature to 37.5℃ and the initial humidity to 50%, turning the eggs once every 2 hours, turning them 90° each time, and airing the eggs for 4 minutes each day; after the eggs hatch, adjusting the humidity to 70% and stopping the turning and airing of the eggs.

[0027] This invention precisely controls water loss to perfectly match the moisture requirements of scarlet ibis embryonic development, effectively preventing hatching defects such as yolk sac abnormalities, poor umbilical cord development, and cardiac hemorrhage, thus ensuring healthy chick development. The temperature and initial humidity settings simulate a natural incubation environment, providing stable temperature and humidity conditions for embryonic development. The daily egg-turning frequency and angle, combined with egg airing, promote even oxygen supply to the embryo, regulate internal egg temperature, and prevent abnormal implantation. After hatching, adjusting humidity and stopping egg turning and airing provides a suitable humidity environment for chick hatching, reducing mortality caused by hatching difficulties. This invention addresses the high sensitivity of scarlet ibis eggs to water loss by dynamically adjusting incubator humidity based on the optimal daily average water loss, controlling the incubation water loss rate to 14wt%-16wt% and improving the chick survival rate. It optimizes parameters such as temperature, humidity, egg turning, and egg drying, ensuring normal embryonic development while resolving the technical contradiction of insufficient water loss in thick-shelled eggs and excessive water loss in thin-shelled eggs, thus improving hatching success rate. Parameter switching before and after hatching achieves environmental adaptation throughout the incubation cycle, preventing abnormal chick development due to parameter mutations and improving survival rate.

[0028] In this invention, the artificially raised brooder feed preferably includes: feed for 1-9 day old chicks comprising the following ingredients by weight: 30-35 parts live loach, 2.5-3.5 parts egg yolk, and 12-15 parts water; feed for 10-20 day old chicks comprising the following ingredients by weight: 20-25 parts live loach, 10-13 parts shrimp, 2.5-3.5 parts egg yolk, and 12-15 parts water; after 21 days of age: in addition to the feed for 10-20 day old chicks, live mealworms are provided for independent feeding, gradually transitioning to adult bird feed. More preferably, the following ingredients are included in the feed for 1-9 day old chicks: 33 parts live loach, 3 parts egg yolk and 14 parts water; the following ingredients are included in the feed for 10-20 day old chicks: 33 parts live loach, 11 parts shrimp, 3 parts egg yolk and 14 parts water; after 21 days of age: in addition to the feed for 10-20 day old chicks, live mealworms are provided for independent feeding, gradually transitioning to adult bird feed.

[0029] This invention designs a formula to address the differences in digestive capacity and nutritional needs of chicks at different stages. Chicks aged 1-9 days are fed mainly fine fish paste to match their weak digestive capacity and avoid indigestion. Chicks aged 10-20 days are fed an increased proportion of shrimp to strengthen protein supply and meet their rapid growth needs. After 21 days, live mealworms are introduced to gradually transition to adult bird feed, helping them develop independent feeding abilities. This invention solves the problem of indigestion or nutritional deficiencies caused by the current one-size-fits-all approach to feed.

[0030] In this invention, the preferred feeding frequency includes: 5-7 meals per day for birds aged 1-7 days, 4-6 meals per day for birds aged 8-14 days, 3-5 meals per day after reaching 200g in weight, and 2-3 meals per day after they learn to feed independently. Before they learn to feed independently, the amount of food given at each meal should not exceed 10% of their body weight, and daily weight gain should be controlled at 10%-15%. After they learn to feed independently, the amount of food given and the weight gain are determined by the bird's appetite. A more preferred feeding frequency includes: 6 meals per day for birds aged 1-7 days, 5 meals per day for birds aged 8-14 days, 4 meals per day after reaching 200g in weight, and 2 meals per day after they learn to feed independently; the amount of food given at each meal should not exceed 10% of their body weight. Controlling the feeding frequency and the amount of food given at each meal can avoid gastrointestinal diseases caused by overfeeding and ensure balanced growth and development.

[0031] In this invention, the preferred method for preparing the feed includes: weighing the appropriate raw materials according to the age of the chicks, mixing them into a paste, and freezing them at -18 to -22°C for 45-50 hours; before feeding, thawing the feed at 2-5°C and then warming it to 38-40°C with boiling water. Freezing can inactivate some microorganisms and reduce the content of pathogenic bacteria, while the thawing and warming steps ensure the feed is fresh and at a suitable temperature, avoiding gastrointestinal irritation in chicks.

[0032] In this invention, the feed for artificial brooding is preferably supplemented with the following additives before feeding: vitamin B1, vitamin B2, vitamin B6, vitamin B12, B complex vitamins, vitamin C, multi-enzyme tablets, water-soluble calcium, probiotics, vitamin AD and electrolyte multivitamins.

[0033] This invention's multi-enzyme tablets and probiotics can solve the problems of poor digestion and absorption in chicks; the addition of vitamin B prevents neurological symptoms; vitamins A and D and calcium can solve the calcium deficiency problem caused by rapid growth; other vitamins improve the chicks' resistance. Electrolyte multivitamins can alleviate the stress symptoms that scarlet ibises experience due to their highly neurotic nature, especially when changing environments or caretakers (which can lead to liver rupture and death in severe cases).

[0034] In this invention, the artificial brooding preferably includes: 1-14 days old: setting the initial temperature of the brooding box at 37-38℃, decreasing it by 0.3-0.7℃ daily; after 15 days old: gradually removing the chicks from the brooding box and transferring them to a metal cage at time gradients of 0.5-1.5h, 5-7h, 10-15h, and 20-28h per day; after the chicks begin to feed on live mealworms independently: gradually removing them from the metal cage and transferring them to a large outdoor rearing cage at time gradients of 0.5-1.5h, 5-7h, 10-15h, and 20-28h per day; after 3 months old: transferring them to the exhibition area for rearing. More preferably, the following measures are taken: 1-14 days old: set the initial temperature of the brooder box to 37.5℃ and decrease it by 0.5℃ each day; after 15 days old: gradually remove the chicks from the brooder box and transfer them to a metal cage according to the time gradient of 1h, 6h, 12h, and 24h each day; after the chicks start to eat live mealworms on their own: gradually remove them from the metal cage and transfer them to a large outdoor rearing cage according to the time gradient of 1h, 6h, 12h, and 24h each day; after 3 months old: transfer them to the exhibition area for rearing.

[0035] This invention addresses the increased stress response in Scarlet Ibis chicks after 15 days of age by employing a gradient cooling and transitional environmental control method: The initial temperature of the brooder box is controlled from 1 to 14 days of age to simulate the gradual development of the chicks' thermoregulation ability, avoiding stress caused by sudden temperature changes. After 15 days, the chicks are gradually removed from the brooder box and transferred to a metal cage. Once they can feed independently, they are transferred to a large outdoor rearing cage at the same gradient. This gradual environmental adaptation alleviates the stress response of the Scarlet Ibis chicks and enhances their environmental adaptability. After 3 months of age, they are transferred to an exhibition area. By this time, the chicks have developed independent survival skills and can gradually adapt to a natural rearing environment, completing a smooth transition from artificial breeding to exhibition display. This invention's gradual environmental change model highly matches environmental changes with the physiological development rhythm of the chicks, ensuring their sense of security while simultaneously developing their environmental adaptability, thus increasing their survival rate.

[0036] In this invention, disease prevention and control are also preferably included, which preferably includes: testing the feces of chicks; when starch granules > 2 / μg and no white blood cells are found, increasing the feeding amount of probiotics and multi-enzyme tablets; when the number of white blood cells in the feces > 5 / μg, feeding 5% enrofloxacin daily for 3-5 consecutive days.

[0039] Unless otherwise specified, the following embodiments are all conventional methods.

[0040] Unless otherwise specified, all materials and reagents used in the following examples are commercially available.

[0041] The enclosure environment for the scarlet ibis in the examples and comparative examples is as follows: Chengdu Zoo is located in the northeast of Chengdu City. The scarlet ibis exhibit is located in the northwest of the zoo, facing the waterfowl lake, backed by a perimeter wall, and adjacent to a residential area. The highest temperature in the exhibit area reaches above 40℃ throughout the year, and the lowest temperature is 0℃. The exhibit area is 4 m high and covers an area of ​​approximately 100 m². 2 The viewing area is made of glass. In the center of the exhibit is a pool measuring 2m long, 1.5m wide, and 15-20cm deep. A 60cm high wooden frame is provided above the pool to hold feeding dishes to meet the crested ibis's feeding needs. Perches of different heights are built in layers throughout the exhibit, and rope ladders are installed under the canopy to meet the crested ibis's needs for resting and standing. Mulberry trees are planted in the exhibit to provide shade for the crested ibis, and they can also be used to build nests during the breeding season. A small number of plants such as spring feathers and monstera are planted on the ground to provide hiding spaces for the crested ibis.

[0042] The Chengdu Zoo is raising 14 scarlet ibises (9 females and 5 males), who will gradually reach sexual maturity in 2024.

[0043] The incubator was a Brinsea Zoo28EX from the UK; the brooder box was a Brinsea TLC-50Adv from the UK.

[0044] The method for adding the additives is as follows: Take one tablet each of vitamin B1 (containing 10mg / tablet), vitamin B2 (containing 5mg / tablet), vitamin B6 (containing 10mg / tablet), vitamin B12 (containing 25μg / tablet), compound vitamin B (containing 3mg / tablet of VB1, 1.5mg / tablet of VB2, 0.2mg / tablet of VB6, 10mg / tablet of nicotinic acid, and 1mg / tablet of calcium pantothenate), vitamin C (containing 100mg / tablet of VC), and multi-enzyme tablets (0.3g / tablet), mix them together, grind them into powder, mix them with the feed, add 1 drop of water-soluble calcium, 100mg of probiotics, 33mg of vitamin AD and 0.5g of electrolytic multivitamins, and mix well.

[0045] The water-soluble calcium is bird-grade water-soluble calcium-phosphorus solution, sourced from Jingzhou Puxinno Technology Industry Co., Ltd.; the probiotics are Bacillus subtilis dual live bacteria granules, sourced from Beijing Hanmei Pharmaceutical Co., Ltd.; vitamin AD is sourced from Sinopharm Holding Xingsha Pharmaceutical (Xiamen) Co., Ltd.; and the electrolytic multivitamins are sourced from Xinyi Mochongle Pet Products Co., Ltd.

[0046] Example 1 (1) Adult bird rearing Feed for adult scarlet ibises: 35g beef, 2g dried shrimp, 10g egg yolk, 10g mixed grain steamed buns, 35g cooked carrots, 35g tomatoes, 10g apples, 20g watermelon, 30g crucian carp, 20g shrimp, and 60g loach. The feeding method is as follows: cut beef, egg yolk, cooked carrot, crucian carp, shrimp, mixed grain steamed buns, tomato, apple, and watermelon into pieces, grind the chopped materials into pellets using a meat grinder, and put them into the feed trough; the loaches will feed on their own. Feed each adult bird 200g of feed per day, divided into two feedings per day. Observe the adult birds' mental state, feeding, and droppings daily, and record changes in feather color (bright red during the breeding season); monitor changes in beak color, and mark the birds as entering the breeding and pairing period when the beak turns from red to black, and strengthen subsequent behavioral observation; clean up droppings, leftover feed, and debris in the exhibition area in a timely manner, and disinfect feeding dishes and water pools regularly to prevent the spread of diseases.

[0047] (2) Reproduction and fertilization Once the breeding and pairing period begins, a successful pairing is considered to occur when both male and female individuals mate repeatedly. Successfully paired scarlet ibises begin nest building and continue mating during the nest building process. The appearance of persistent nest-sitting behavior indicates the start of incubation. After all scarlet ibises have laid a round of eggs, the eggs are collected and artificially incubated. During the breeding and fertilization period, the amount of dried shrimp in the feed is dynamically adjusted according to the water loss of the bird eggs: After collecting the bird eggs, artificial incubation is carried out. The humidity of the incubator is adjusted according to the optimal daily water loss (optimal daily water loss (g) = 0.0074 × initial egg weight - 0.0086) until the optimal daily water loss is reached. If the daily water loss is still lower than the optimal daily water loss after adjusting the humidity of the incubator within 5 days, the dried shrimp in the feed is removed; if the daily water loss is still higher than the optimal daily water loss after adjusting the humidity of the incubator within 5 days, 2g of dried shrimp is added to the feed. (3) Artificial incubation Disinfect the incubator with F10, set the incubation program to a temperature of 37.5℃ and an initial humidity of 50%. Adjust the humidity of the incubator dynamically according to the optimal daily water loss (optimal daily water loss (g) = 0.0074 × initial egg weight - 0.0086). Turn the eggs once every 2 hours, turning them 90° each time, and let them air dry for 4 minutes each day. After hatching, set the humidity to 70% and stop turning and airing the eggs. The artificial incubation period is 22±1 days, and the water loss rate of the bird eggs is controlled at 15±1wt%.

[0048] (4) Artificial brooding 1) Feed Feed for 1-9 day old scarlet ibises: Mix 330g of live loach, 30g of egg yolk and 140g of sterile water and mash into a paste. Freeze at -20℃ for 48 hours. Before feeding, thaw at 4℃ and heat to 39℃ in a boiling water bath. Before feeding, add 39℃ sterile water and additives (0.5% of the feed weight) to dilute the feed to a consistency that can be drawn with a 5mL dropper. The feed formula for 10-20 day old scarlet ibises is as follows: 220g of live loach with no obvious external injuries, 110g of shrimp meat, 30g of egg yolk and 140g of sterile water are mixed and mashed into a paste; frozen at -20℃ for 48 hours, thawed at 4℃ before feeding, and heated to 39℃ in a boiling water bath. Add additives (0.7% of feed weight) before feeding. After 21 days: In addition to the feed for 10-20 day old birds, provide live mealworms for them to eat on their own, and gradually transition to adult bird feed.

[0049] 2) Feeding 1-7 days old: Chicks can be fed 24 hours after hatching, 6 meals a day; 8-14 days old, 5 meals a day; Once scarlet ibis chicks reach a weight of 200g, they should be fed four meals a day. Before the bird learns to feed itself, the amount of food given at each meal should not exceed 10% of its body weight, and the daily weight gain should be controlled at 12.5±2.5%. After the bird learns to feed itself, the amount of food given and the weight gain will be determined by the bird's appetite.

[0050] 3) Staged management of fledglings 1-14 days old: Set the initial temperature of the brooder box to 37.5℃, and decrease it by 0.5℃ each day; After 15 days: Gradually remove the brooder from the brooder box and transfer it to a metal cage (60cm×45cm×40cm) according to the time gradient of 1h, 6h, 12h and 24h per day; place the familiar brooder bowl in the metal cage; After feeding on live mealworms on their own: gradually remove them from the metal cage according to the time gradient of 1 hour, 6 hours, 12 hours and 24 hours per day, and transfer them to a large outdoor rearing cage; after the scarlet ibis chicks have adapted to the outdoor environment, the metal cage door can be opened to allow the chicks to choose whether to come out of the cage. Once the chicks are willing to move around outside the small metal cage, gradually close the metal cage door and no longer allow the chicks to enter. After 3 months of age: transferred to the exhibition area for rearing.

[0051] (5) Disease prevention and control If no obvious begging behavior is observed before or after feeding, or if the color, shape, or odor of the feces is abnormal, a fecal test should be performed: Abnormal stool, stool test showed starch granules >2 / μg, but no white blood cells, increase probiotics and multi-enzyme tablets daily; If the stool is abnormal and the white blood cell count in the stool is >5 / μg, feed the patient 5% enrofloxacin daily for 3 consecutive days.

[0052] Example 2 (1) Adult bird rearing Feed for adult scarlet ibises: 32g beef, 1.5g dried shrimp, 12g egg yolk, 8g mixed grain steamed buns, 38g cooked carrots, 32g tomatoes, 12g apples, 18g watermelon, 32g crucian carp, 18g shrimp, and 65g loach. The feeding method is as follows: cut beef, egg yolk, cooked carrot, crucian carp, shrimp, mixed grain steamed buns, tomato, apple, and watermelon into pieces respectively. Mix the chopped materials with shrimp shells, grind them into pellets using a meat grinder, and put them into the feed trough; the loaches will eat on their own. Feed each adult bird 150g of feed per day, divided into two feedings per day. Observe the adult birds' mental state, feeding, and droppings daily, and record changes in feather color (bright red during the breeding season); monitor changes in beak color, and mark the birds as entering the breeding and pairing period when the beak turns from red to black, and strengthen subsequent behavioral observation; clean up droppings, leftover feed, and debris in the exhibition area in a timely manner, and disinfect feeding dishes and water pools regularly to prevent the spread of diseases.

[0053] (2) Reproduction and fertilization Once the breeding and pairing period begins, a successful pairing is considered to occur when both male and female individuals mate repeatedly. Successfully paired scarlet ibises begin nest building and continue mating during the nest building process. The appearance of persistent nest-sitting behavior indicates the start of incubation. After all scarlet ibises have laid a round of eggs, the eggs are collected and artificially incubated. During the breeding and fertilization period, the amount of dried shrimp in the feed is dynamically adjusted according to the water loss of the bird eggs: After collecting the bird eggs, artificial incubation is carried out. The humidity of the incubator is adjusted according to the optimal daily water loss (optimal daily water loss (g) = 0.0074 × initial egg weight - 0.0086) until the optimal daily water loss is reached. If the daily water loss is still lower than the optimal daily water loss after adjusting the humidity of the incubator within 5 days, the dried shrimp in the feed is removed; if the daily water loss is still higher than the optimal daily water loss after adjusting the humidity of the incubator within 5 days, 1.5g of dried shrimp is added to the feed. (3) Artificial incubation Disinfect the incubator with F10, set the incubation program to a temperature of 37℃ and an initial humidity of 48%. Adjust the humidity of the incubator dynamically according to the optimal daily water loss (optimal daily water loss (g) = 0.0074 × initial egg weight - 0.0086). Turn the eggs once every 1.5 hours, turning them 80° each time, and let them air dry for 3 minutes each day. After hatching, set the humidity to 68%, and stop turning and airing the eggs. The artificial incubation period is 22±1 days, and the water loss rate of the bird eggs is controlled at 15±1wt%.

[0054] (4) Artificial brooding 1) Feed Feed for 1-9 day old scarlet ibises: Mix 300g of live loach, 25g of egg yolk and 120g of sterile water and mash into a paste. Freeze at -18℃ for 50 hours. Before feeding, thaw at 4℃ and heat to 38℃ in a boiling water bath. Before feeding, add 38℃ sterile water and additives (0.4% of the feed weight) to dilute the feed. The consistency should be such that it can be drawn with a 5mL dropper. The feed formula for 10-20 day old scarlet ibises is as follows: 200g of live loach with no obvious external injuries, 100g of shrimp meat, 25g of egg yolk and 120g of sterile water are mixed and mashed into a paste; frozen at -20℃ for 50 hours, thawed at 4℃ before feeding, and heated to 38℃ in a boiling water bath. Add additives (0.6% of feed weight) before feeding. After 21 days: In addition to the feed for 10-20 day old birds, provide live mealworms for them to eat on their own, and gradually transition to adult bird feed.

[0055] 2) Feeding 1-7 days old: Chicks can be fed 24 hours after hatching, 5 meals a day; 8-14 days old, 4 meals a day; Once the scarlet ibis chicks reach a weight of 200g, they should be fed three meals a day. After starting to forage independently, feed them twice a day. Before the bird learns to feed itself, the amount of food given at each meal should not exceed 10% of its body weight, and the daily weight gain should be controlled at 12.5±2.5%. After the bird learns to feed itself, the amount of food given and the weight gain will be determined by the bird's appetite.

[0056] 3) Staged management of fledglings 1-14 days old: Set the initial temperature of the brooder box to 37℃, and decrease it by 0.3℃ each day; After 15 days: Gradually remove the brooder from the brooder box and transfer it to a metal cage (60cm×45cm×40cm) according to the time gradient of 0.5h, 5h, 10h and 20h per day; place the familiar brooder bowl in the metal cage; After feeding live mealworms independently: gradually remove them from the metal cage according to the time gradient of 0.5h, 5h, 10h and 20h per day, and transfer them to a large outdoor rearing cage; after the scarlet ibis chicks have adapted to the outdoor environment, the metal cage door can be opened to allow the chicks to choose whether to come out of the cage. Once the chicks are willing to move around outside the small metal cage, gradually close the metal cage door and no longer allow the chicks to enter. After 3 months of age: transferred to the exhibition area for rearing.

[0057] (5) Disease prevention and control If no obvious begging behavior is observed before or after feeding, or if the color, shape, or odor of the feces is abnormal, a fecal test should be performed: Abnormal stool, stool test showed starch granules >2 / μg, but no white blood cells, increase probiotics and multi-enzyme tablets daily; If the stool is abnormal and the white blood cell count in the stool is >5 / μg, feed the patient 5% enrofloxacin daily for 4 consecutive days.

[0058] Example 3 (1) Adult bird rearing Feed for adult scarlet ibises: 38g beef, 2.5g dried shrimp, 8g egg yolk, 12g mixed grain steamed buns, 32g cooked carrots, 38g tomatoes, 8g apples, 23g watermelon, 28g crucian carp, 23g shrimp, and 55g loach; The feeding method is as follows: cut beef, egg yolk, cooked carrot, crucian carp, shrimp, mixed grain steamed buns, tomato, apple, and watermelon into pieces respectively. Mix the chopped materials with shrimp shells, grind them into pellets using a meat grinder, and put them into the feed trough; the loaches will eat on their own. Each adult bird is fed 220g of feed per day, divided into two feedings per day. Observe the adult birds' mental state, feeding, and droppings daily, and record changes in feather color (bright red during the breeding season); monitor changes in beak color, and mark the birds as entering the breeding and pairing period when the beak turns from red to black, and strengthen subsequent behavioral observation; clean up droppings, leftover feed, and debris in the exhibition area in a timely manner, and disinfect feeding dishes and water pools regularly to prevent the spread of diseases.

[0059] (2) Reproduction and fertilization Once the breeding and pairing period begins, a successful pairing is considered to occur when both male and female individuals mate repeatedly. Successfully paired scarlet ibises begin nest building and continue mating during the nest building process. The appearance of persistent nest-sitting behavior indicates the start of incubation. After all scarlet ibises have laid a round of eggs, the eggs are collected and artificially incubated. During the breeding and fertilization period, the amount of dried shrimp in the feed is dynamically adjusted according to the water loss of the bird eggs: After collecting the bird eggs, artificial incubation is carried out. The humidity of the incubator is adjusted according to the optimal daily water loss (optimal daily water loss (g) = 0.0074 × initial egg weight - 0.0086) until the optimal daily water loss is reached. If the daily water loss is still lower than the optimal daily water loss after adjusting the humidity of the incubator within 5 days, the dried shrimp in the feed is removed; if the daily water loss is still higher than the optimal daily water loss after adjusting the humidity of the incubator within 5 days, 2.5g of dried shrimp is added to the feed. (3) Artificial incubation Disinfect the incubator with F10, set the incubation program to a temperature of 38℃ and an initial humidity of 52%. Dynamically adjust the humidity of the incubator according to the optimal daily water loss (optimal daily water loss (g) = 0.0074 × initial egg weight - 0.0086). Turn the eggs once every 2.5 hours, turning them 100° each time, and let them air dry for 5 minutes each day. After hatching, set the humidity to 72% and stop turning and airing the eggs. The artificial incubation period is 22±1 days, and the water loss rate of the bird eggs is controlled at 15±1wt%.

[0060] (4) Artificial brooding 1) Feed Feed for 1-9 day old scarlet ibises: Mix 350g of live loach, 35g of egg yolk and 150g of sterile water and mash into a paste. Freeze at -22℃ for 45 hours. Before feeding, thaw at 4℃ and heat to 40℃ in a boiling water bath. Before feeding, add 40℃ sterile water and additives (0.6% of the feed weight) to dilute the feed to a consistency that can be drawn with a 5mL dropper. The feed formula for 10-20 day old scarlet ibises is as follows: 250g of live loach with no obvious external injuries, 130g of shrimp meat, 35g of egg yolk and 150g of sterile water are mixed and mashed into a paste; frozen at -20℃ for 45 hours, thawed at 4℃ before feeding, and heated to 38℃ in a boiling water bath. Add additives (0.8% of feed weight) before feeding. After 21 days: In addition to the feed for 10-20 day old birds, provide live mealworms for them to eat on their own, and gradually transition to adult bird feed.

[0061] 2) Feeding 1-7 days old: Chicks can be fed 24 hours after hatching, 7 meals a day; 8-14 days old, 6 meals a day; Once scarlet ibis chicks reach a weight of 200g, they should be fed five meals a day. After starting to forage independently, the animal will eat three meals a day. Before the bird learns to feed itself, the amount of food given at each meal should not exceed 10% of its body weight, and the daily weight gain should be controlled at 12.5±2.5%. After the bird learns to feed itself, the amount of food given and the weight gain will be determined by the bird's appetite.

[0062] 3) Staged management of fledglings 1-14 days old: Set the initial temperature of the brooder box to 38℃, and decrease it by 0.7℃ each day; After 15 days: Gradually remove the brooder from the brooder box and transfer it to a metal cage (60cm×45cm×40cm) according to the time gradient of 1.5h, 7h, 15h and 28h per day; place the familiar brooder bowl in the metal cage; After feeding on live mealworms on their own: gradually remove them from the metal cage according to the time gradient of 1.5h, 7h, 15h and 28h per day, and transfer them to a large outdoor rearing cage; after the scarlet ibis chicks have adapted to the outdoor environment, the metal cage door can be opened to allow the chicks to choose whether to come out of the cage. Once the chicks are willing to move around outside the small metal cage, gradually close the metal cage door and no longer allow the chicks to enter. After 3 months of age: transferred to the exhibition area for rearing.

[0063] (5) Disease prevention and control If no obvious begging behavior is observed before or after feeding, or if the color, shape, or odor of the feces is abnormal, a fecal test should be performed: Abnormal stool, stool test showed starch granules >2 / μg, but no white blood cells, increase probiotics and multi-enzyme tablets daily; If the stool is abnormal and the white blood cell count in the stool is >5 / μg, feed the patient 5% enrofloxacin daily for 5 consecutive days.

[0064] Comparative Example 1 Natural breeding (Chengdu Zoo has 14 scarlet ibises (9 females and 5 males), which gradually reached sexual maturity in 2024 and began laying eggs and incubating them naturally in May 2024), all of which failed to hatch.

[0065] Comparative Example 2 The specific artificial breeding method is the same as in Example 1, except that when the beak turns from red to black, the shrimp shells in the feed are not dynamically adjusted.

[0066] Experimental Example 1 Experimental subjects: 14 scarlet ibises (9 females and 5 males) kept at Chengdu Zoo.

[0067] Fourteen scarlet ibises reached sexual maturity in 2024 and began laying eggs in May 2024, which then hatched naturally, but all hatching attempts failed.

[0068] Artificial breeding was carried out using the method of Comparative Example 2 from May to July 2025. However, the eggs laid from May to July had excessively thick shells, which affected the hatching rate and survival rate of the chicks. Therefore, artificial breeding was carried out using the method of Example 1 starting from July 15, 2025.

[0069] (1) Artificial incubation and survival rate Table 1 shows the overall situation of artificial incubation and survival of scarlet ibises.

[0070] The egg candling method is used to observe the fertilization status of the egg: if blood streaks or reticular blood vessels are seen, it indicates that the egg has been fertilized; if the inside is uniformly transparent and shows no changes, it is considered an unfertilized egg. Candling should be done gently and quickly, for no more than one minute at a time, to avoid temperature fluctuations affecting the embryo.

[0071] Fertilization rate (%) = Number of fertilized eggs / Total number of eggs × 100%.

[0072] Table 1. Artificial incubation and survival rate of Scarlet Ibis As shown in Table 1, a total of 23 eggs were laid from May to September 2025, with only one egg failing to fertilize in September, resulting in an overall fertilization rate of 95.7%, significantly better than the common problem of low fertilization rates in American scarlet ibises under existing technologies. Precise formulation design of adult bird feed: adding shrimp shells before breeding ensures the reproductive performance of adult birds; dynamically adjusting the shrimp shells in the feed during the breeding season avoids eggshells being too thin or too thick, which could affect hatching rate and chick survival rate. Based on the survival data, when the shrimp shell formula was not adjusted from May to July, only 1 out of 8 eggs hatched in May and June, and only 1 out of 9 eggs hatched in July. The low survival rate in Comparative Example 2 was due to the excessively thick eggshells, which resulted in a low rate of water loss during hatching. In Example 1, all 5 eggs hatched in August, and 4 out of 5 survived. The hatching rate and survival rate were significantly improved, which verified the advantages of the dynamic regulation of adult bird feed in this invention. It also proved that the feed formula of this invention can accurately match the nutritional needs of the American scarlet ibis during the breeding season, laying the foundation for high fertilization rate and high survival rate.

[0073] (2) Water loss rate during hatching of young birds The hatching water loss rate of hatched chicks was estimated, and the hatching water loss rates of surviving and dead scarlet ibis chicks were statistically analyzed. The specific results are shown in Tables 2 and 3.

[0074] The study also compiled statistics on the age and cause of death of the dead scarlet ibis chicks.

[0075] Water loss rate (%) = (fresh weight of eggs - weight of eggs before hatching) / 21 × 22 / fresh weight of eggs × 100%.

[0076] Table 2. Hatching water loss rate of surviving scarlet ibis chicks Table 3 Information on the dead scarlet ibis chicks in Comparative Example 2 and Example 1 In Table 2, the incubation water loss rate of the six surviving chicks was controlled within the range of 14wt%-16wt%, demonstrating the rationality of the artificial incubation parameter settings of this invention. It is evident that this invention, by dynamically adjusting the shrimp shells in the feed during the breeding season and precisely defining the water loss rate range and corresponding incubation operations, ensures a balance between gas exchange and water regulation during embryonic development, avoiding hatching defects such as yolk sac abnormalities and poor umbilical cord development. The data confirms that the artificial incubation scheme of this invention can provide a stable environment for the healthy development of chicks and is a key technical support for improving survival quality.

[0077] In Table 3, the data shows that two birds died from stress (at 22 days and 17 days old), which confirms the highly neurotic nature of the American scarlet ibis and highlights the importance of stress control measures such as gradual removal from the brooder box and gradual transfer to outdoor cages in the artificial brooding process of this invention.

[0078] Four birds died due to developmental abnormalities (two with yolk sac abnormalities, one with cardiac hemorrhage, and one with umbilical infection). Their corresponding water loss rates were 17.7%, 12.5%, 12.8%, and 12.3%, respectively, all exceeding the optimal range of 14%-16%, directly proving that water loss rate control is a key factor for successful hatching.

[0079] The age distribution of deaths shows that 4 birds died before 15 days of age and 2 birds died after 15 days of age. This reflects the phased characteristics of young birds with poor water loss rates dying before 15 days of age due to congenital defects and increasing stress sensitivity after 15 days of age. The feed formula, feeding frequency and disease prevention and control program designed for different ages in this invention are precisely targeted at these vulnerable stages.

[0080] Case of weak digestive function in infants under 15 days old: Table 2 shows that animal number 3, at 5 days old, was found to be lethargic and had foul-smelling feces. A fecal examination revealed white blood cells in the feces. After being fed 5% enrofloxacin for 3 days, it recovered.

[0081] Table 2 shows that animal number 4, at 7 days old, was found to be lethargic and had foul-smelling feces. Fecal examination revealed white blood cells in the feces. After feeding it 5% enrofloxacin for 3 days, fecal examination revealed starch granules in the feces but no white blood cells. The amount of probiotics and multi-enzyme tablets was increased daily, and it gradually recovered.

[0082] The above data, from the opposite perspective, confirms the comprehensiveness and relevance of the technical system of this invention, and provides data support for solving the problem of low survival rate of chicks in existing breeding.

[0083] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
