CATDOLL : CATDOLL: Duckling hatching technology? How many days does it take to hatch ducklings in an incubator?

1. Duckling hatching technology?

1. Preparation before incubation

(1) Check the incubator and conduct a test run. Observe the operation of the motor, temperature/humidity controller, alarm, ventilation, egg turning and other systems. The test run time is 3 days.

(2) Calibrate the temperature inside the incubator. Use a human body thermometer to measure the temperature of the top, middle, bottom, front, back, left, right, inside and outside of the incubator. The temperature difference between the various parts of the incubator should be less than 0.2°C. If it is not, find the cause and wait until it is properly adjusted before incubating.

(3) Cleaning and disinfection. After each batch of chicks has hatched, the incubator, egg trays, and the inside and outside of the hatchery should be thoroughly cleaned, rinsed, and disinfected.

1. Temperature and humidity: In the early stage of incubation (1-15 days), the temperature in the incubator should be controlled between 38.5°C and 38°C, and in the middle stage (16-30 days), it should be controlled between 38°C and 37.5°C. The humidity should be 60% in the early stage of incubation, 50% in the middle stage, and 60%-70% in the late stage and when hatching.

2. Turn the eggs: Turn the eggs more often, every 2.5 hours, at an angle of 180°, and turn the eggs manually twice a day.

3. Cooling eggs: You don’t need to cool the eggs in the early stage of incubation, but you can cool the eggs once a day in the middle stage and 3-4 times a day in the later stage.

4. Water spraying: From the middle of incubation to hatching, spray the eggs once with 35°C warm water when they are cooling down. After they are dried, put them into the machine to continue incubation.

5. Ventilation: The incubator should have an electric fan with ventilation holes to ensure uniform temperature and air circulation inside the machine. This is especially important in the middle and late stages of incubation. If necessary, slightly open the door.

6. Assisted production: The broiler ducklings will hatch after 35 days of incubation. Those with difficulty in hatching should be artificially broken to increase the hatching rate.

7. In spring, summer and autumn, you can also use solar hot water bag heat source electric incubator, which only costs 2 cents per day for every 1,000 eggs.

2. How many days does it take to hatch ducklings in an incubator?

The requirements for temperature and humidity of duckling hatching are as follows: if the incubator sensor is placed in the space outside the egg tray in the incubator, the temperature of the incubator space is 38.5 degrees on the 1st to 7th day after incubation, 38 degrees on the 8th to 25th day, and 37 degrees on the 26th to 28th day. If the incubator sensor is placed on the breeding eggs in the egg tray, the egg temperature can be kept at 37.8-38 degrees from beginning to end.

3. Is it good to artificially hatch ducklings?

Artificially hatched ducklings should have a higher success rate than ducks

4. What are the requirements for setting up a duck hatchery?

Preparation of the chemical field:

1. Preparation of the incubator: The incubator should be separated from the breeding farm by a certain distance (at least 150m), and the incubator should be tight, well-insulated, and well-ventilated. The temperature of the incubator is 20-24℃, and it rises to 30℃ when the chicks are hatched; the relative humidity is 55%-60%, and it increases to 60%-65% when the chicks are hatched.

2. Hatching process flow: The process flow of the hatchery is: collection of breeding eggs → disinfection, storage and grading of breeding eggs → incubation → transfer of trays → grading, identification and vaccination of ducklings → storage of ducklings → distribution of ducklings.

3. Preparation of the incubator: Before hatching, the incubator should be inspected, disinfected, and tested before hatching. After inspection, it should be thoroughly cleaned, fumigated and disinfected, and then tested two days before hatching. It can only be hatched after it is operating normally.

Selection, storage, disinfection and preparation of eggs for transport

1. Breeding eggs should preferably come from breeds with high and stable production performance and no egg-borne diseases such as pullorum, mycoplasma, Marek's disease, etc. The surface should be clean, and the egg weight and eggshell color should meet the breed requirements.

2. Storage of breeding eggs: A special egg warehouse is set up to store breeding eggs. The suitable temperature is 12~15℃ and the humidity is 70%~80%. Note: The storage period should not exceed two weeks. It is best to place the breeding eggs with the blunt end facing down.

3. Transport of breeding eggs: Use special egg boxes to prevent collision and shock. Place the eggs with the blunt end facing upwards.

4. Disinfection of breeding eggs: Disinfect eggs as soon as possible after collecting them, and disinfect them again before hatching.

5. Where are the duck hatcheries in Hebei?

There is a Galaxy hatchery in Baoding, Hebei

6. What is the specific temperature and humidity for hatching ducklings?

The requirements for temperature and humidity of duckling hatching are as follows: if the incubator sensor is placed in the space outside the egg tray in the incubator, the temperature of the incubator space is 38.5 degrees on the 1st to 7th day after incubation, 38 degrees on the 8th to 25th day, and 37 degrees on the 26th to 28th day. If the incubator sensor is placed on the breeding eggs in the egg tray, the egg temperature can be kept at 37.8-38 degrees from beginning to end.

7. Weaned ducklings breeding technology?

The temperature for the first three days of brooding is 30-32 degrees. Starting from the fourth day, depending on the situation of the ducklings, the temperature can be adjusted down by 0.5-1 degree every day to ensure that the indoor temperature is around 20-22 degrees at the end of brooding. Since it is winter brooding, the indoor temperature depends on the temperature and the weaning time will be appropriately delayed.

As for temperature, the most important thing is to keep it stable. It should not fluctuate too high or too low. The temperature should be adjusted appropriately according to the performance of the ducklings.

Ducklings huddle together close to the heat source, with their down standing upright, their bodies curled up, and they often make sharp cries, indicating that the temperature is too low.

The ducklings are away from the heat source, panting with their mouths open, their back feathers are wet, their water intake increases, and their feed intake decreases, indicating that the temperature is too high.

8. What will happen if the eggs are not dried when hatching ducklings?

The main purpose of drying eggs is to dissipate the excess physiological heat in the eggs and provide sufficient oxygen to the embryo, preventing overheating accidents and suffocation of the embryo due to lack of oxygen.

The eggs are incubated at a constant temperature. The eggs are incubated at a variable temperature. The variable temperature incubation simulates the incubation process of hens.

9. Meat pigeon hatching technology?

In meat pigeon farming, there are two ways to hatch young pigeons. One is natural hatching and the other is artificial hatching. Below we will give a brief description of these two hatching methods.

Natural incubation:

After the pigeons are paired, they will continue to breed, with the female pigeon crouching in the nest for a long time. After the second egg is laid, the parent pigeon will start to incubate the eggs. During the process of the parent pigeon incubating the eggs, the following management work should be paid attention to and carried out:

1. Keep the environment quiet, avoid external interference and stress factors, and provide appropriate light shielding for the pigeon cages when necessary to encourage the parent pigeons to concentrate on incubating eggs.

2. The nesting material should preferably be double-layered old linen, with rice husks, sawdust or dry fine sand under the linen. Dry fine sand is ideal, with a thickness of 2 to 3 cm in the nesting basin. The breeder should check the egg laying and hatching every day, and pick out any damaged eggs in time.

3. Improve the nutritional level of feed during the egg-laying period, ensure that the crude protein content reaches 18-20%, and the energy level is also increased accordingly. Make the parent pigeons have a strong physique and lay a good foundation for feeding the young pigeons. Prevent the eggshells from being contaminated with feces, because bacteria may invade the eggs and cause embryo death. If they are stained with feces, wipe them clean with gauze.

4. Candling is a must. Candling is done once on the 5th and 10th days of incubation. During the first candling, if reddish-brown blood vessels are found in the egg in a spider web-like shape and the shape is stable, it is a fertilized egg and the egg should continue to be incubated. If there are blood vessels in the egg, but they are a thick line and U-shaped, it is a dead sperm egg; if it is transparent and has no blood vessels, it is an unfertilized egg, and dead sperm eggs and unfertilized eggs should be picked out. Candling is done for the second time on the 10th day of incubation. If most of the egg is black, and the other end forms a relatively transparent blank area due to the enlargement of the air chamber, it means that the embryo is developing healthily; if the egg is not clearly black and white, the material in the egg is unstable, there is a sense of fluctuation when turning the egg, and the eggshell is gray, it is a dead embryo egg and should be removed in time.

5. Timely combine the eggs, because combining eggs is one of the effective measures to improve the reproductive capacity of meat pigeons. After taking out the infertile eggs, dead sperm eggs and dead embryo eggs, combine 2 eggs per nest into one nest, and combine the remaining eggs into other nests with the same incubation period or 1 day difference. It is better to combine nests after 10 days. If nests are combined before 10 days, those pigeons with empty nests can lay eggs in about 8 days. Early egg laying will affect the pigeons' physical recovery, and the next nest may not be very energetic, or there may be infertile eggs, dead sperm eggs, dead embryo eggs, etc.

6. It is very important to know the date of hatching. 7-8 days after the second egg candling, pay attention to the hatching of the squab. If it is really difficult to hatch, artificial help is needed. Generally, if the shell surface is only pecked with a small hole after the 18th day of incubation, artificial assistance is needed to remove the shell. If the shell has not been pecked after more than 18 days of incubation, the embryo may have died.

7. The incubation temperature of pigeons is very important and should be kept at a suitable temperature. In winter, the temperature in the room should be kept at least above 5 ℃. If the temperature is too low, the room should be heated, otherwise it is easy to freeze to death in the early stage of incubation. In the hot summer, it is necessary to reduce the bedding appropriately, open the doors and windows, and start the exhaust fan to keep the room temperature below 32 ℃, otherwise it is easy to cause stillbirth in the late stage of incubation.

Artificial incubation:

Artificial incubation can avoid crushing eggs during incubation, prevent pigeon feces pollution, reduce unfavorable factors such as embryo death during incubation, improve the hatching rate and hatching rate of meat pigeons, shorten the egg-laying cycle of breeder pigeons, speed up reproduction, and improve the reproduction rate. Experiments have shown that the average egg-laying cycle of natural incubation is 63 days, while the average egg-laying cycle of artificial incubation can be shortened to 50 days. Based on this estimate, the egg-laying rate of pigeons can be increased by nearly 4 times, and artificial incubation technology should be promoted and applied in meat pigeon production as soon as possible.

1. Preparation before incubation

① Incubator: Use a small flat incubator, such as a chicken incubator, and replace the egg rack for incubating chicken eggs with the egg rack for incubating pigeon eggs. Perform maintenance, disinfection, and temperature testing on the incubator. Keep the incubator away from heat sources and avoid direct sunlight.

② Breeding eggs: Breeding eggs should be selected and disinfected. Fertilized eggs that meet the requirements of the breed, have a moderate egg weight, normal egg shape, and uniform eggshell thickness should be selected as breeding eggs. The disinfection of breeding eggs is very important. The hatching rate of disinfected breeding eggs is significantly higher than that of undisinfected breeding eggs. Use formaldehyde gas fumigation disinfection method, use potassium permanganate chocolate and formalin 30 ml per cubic meter of space, and fumigate for 20 minutes at a temperature of 27-30 ℃. Then move to the incubator for incubation.

2. Incubation conditions: The key to artificial incubation of pigeon eggs is to control the temperature, humidity, egg turning and other conditions to create a good environment for embryonic growth and development, so as to improve the hatching results.

① Temperature: Temperature is the most important condition in the incubation of meat pigeons. Only at a suitable temperature can the normal metabolism and growth and development of the embryo be guaranteed. The temperature required by the embryos at different stages of development is slightly different. The incubation temperature is 38.7℃ for 1-7 days, 38.3℃ for 8-14 days, and 38℃ after 14 days. 2. Humidity. The relative humidity during the incubation period is 60-70%. Some suggest that the relative humidity should reach 80% when the meat pigeons hatch. Generally speaking, the humidity should be high in the early and late stages of incubation and low in the middle stage. This is conducive to the metabolism of the embryo, gas metabolism, and the absorption and evaporation of water; it is also conducive to the uniform heating of the eggs and the hatching of the embryos during the hatching period.

② Turning eggs: The purpose of turning eggs is to prevent the embryo from being attached to the shell membrane; to adjust the temperature of the egg so that the embryo is heated evenly; to help the embryo move and maintain a normal fetal position; to increase the contact area between the yolk sac blood vessels, allantois blood vessels, yolk and egg white, which is beneficial to the absorption of nutrients. Generally, eggs are turned twice on the day of incubation, and then turned 6 times a day until 2 days before hatching.

3. Check the embryonic development: During the incubation process, check whether the embryonic development is normal, so as to timely detect the phenomenon of poor hatching, find out the cause and take improvement measures. The specific operation refers to the egg candling of natural incubation.

4. Hatching: On the 6th day of incubation, transfer the eggs to the hatcher. After 1-2 days of incubation, the chicks will hatch. The best time for hatching is about 24 hours. Chicks that hatch too late or too early are not healthy. After hatching, the hatcher should be cleaned and disinfected for use next time.

5. Incubation records: For each incubation, the date of incubation, number of eggs, source of eggs, previous egg-checking, incubation batches, incubation results, temperature changes during the incubation period, etc. should be recorded for reference when analyzing the incubation results. The record form can be designed by yourself.

After artificial incubation, the hatchlings no longer have the task of feeding the baby pigeons and need to be raised artificially.

10. River shrimp hatching technology?

During the hatching process, new water needs to be added regularly to keep the water fresh. The shrimp eggs will hatch after 20 to 25 days. When the eggs become transparent and eye spots appear on the embryos, apply 50 to 100 kg of decomposed organic fertilizer per mu. When 80% of the shrimps in the shrimp pond have hatched into larvae, use ground traps to catch the broodstock and sell them on the market.
