Does moisture affect egg hatching?

Egg incubation is an important part of chicken production, and the hatchability rate directly affects the economic benefits of chicken production. In order to achieve ideal hatchability and quality chicks, incubation conditions are a key measure, in addition to developing healthy, productive flocks, improving egg quality and enhancing egg disinfection. Next, I will explain in detail how moisture affects egg hatching.

First, the role of water.

Water has a heat conduction effect, which can evenly heat the embryo in the early stage of the incubator, which is conducive to the physiological heat release of the embryo in the later stage of incubation. Improper humidity can affect the evaporation of water in the egg and the metabolism of substances in the embryo; Humidity also favors the appearance of chicks. After the eggshell is hatched, under the action of sufficient humidity and CO2 in the air, the CaCO3 in the eggshell will become Ca(HCO3)2, and the eggshell will become brittle, which is convenient for the chick to come out of the shell.

Second, moisture requirements.

The relative humidity of the incubation chamber and the incubation chamber should be maintained at 60% 65%, the incubator should be kept at 50% 60%, and the incubator should be kept at 65% 75%.

Third, the effect of moisture on the incubation effect.

Embryos have a wide range of adaptation to humidity and are not sensitive to temperature, which generally does not cause a significant decrease in hatchability. However, improper humidity control can affect the quality of young birds. If the humidity is too high, it will prolong the time of shelling, the chicks will be soft, the belly will become larger, and the fluff will stick to the yolk; If the humidity is too low, the eggshells will emerge early, the chicks will shrunk and emaciated, and the fluff will be dry and burnt and sometimes sticky.

Fourth, precautions.

1) The temperature in the incubator is easy to rise in summer, so the air inlet and outlet should be opened. In other seasons, especially winter, the temperature of the incubator is difficult to maintain. The early first eggs (1 to 4 days), because the embryos are still small, they can metabolize the eggs with oxygen, so there is no need for external oxygen, and all the vents are closed, so that the temperature inside the machine rises quickly, it is easy to keep the temperature stable, and it also saves energy.

2) If it is continuous incubation, there are eggs of different stages in the machine, at this time the inlet and exit holes should be opened, and continuous ventilation should be carried out. Especially in the case of incubation in the machine, ventilation should be continued, otherwise the broken embryo or chicks that are prone to appear will suffocate to death.

There will definitely be a big impact, and if the humidity is particularly high, it may affect the sudden death rate of chicks. So there should be a particularly good temperature.

Water does not affect the hatching of eggs, because hens do not drink water when hatching eggs, so water has no effect on egg hatching.

It will definitely affect the hatching of an egg and may even affect the nutrition of this egg. Should go to some of the right places to make a purchase.

Yes, moisture can affect the hatching of eggs because moisture has a heat conduction effect that can cause the heat around the eggs to be affected.

It will affect that water has the function of heat conduction, and the temperature of the hatching eggs should be moderate and not too much change.

In the incubation process of eggs, temperature is the most important condition in the incubation process and plays a decisive role in the hatchability and the health rate of the chicks. If the temperature is not well controlled, it will seriously affect the incubation results. So what is the effect of temperature on incubation during incubation?

First, the importance of temperature.

Temperature is the most important condition for incubation and plays a decisive role in the growth and development of embryos. 37 is the appropriate temperature for the development of chicken embryos. Due to the different incubation equipment and different spawning methods, there are usually two ways to control the temperature during the incubation process, one is variable temperature incubation, and the other is constant temperature incubation.

Different temperature control methods have different grasps of the appropriate temperature for the development of chicken embryos.

Second, the effect of different temperatures on eggs.

In ectothermic culture, the appropriate temperature according to the different stages of embryonic development is: 1 7 days 38 years old. 9 8 18 days old; At the age of 19 21 days, the temperature of the whole incubation period showed a trend of "high and low in the first place".

1) The temperature is too high. High, when the incubation temperature is high, the embryo develops quickly, but the chicks are weak. If the temperature exceeds 42, the embryo dies after 2-3 hours; In addition, it hinders the normal absorption of the contents of the egg, the chick has short villi and lacks pigment.

The weight is small, and the umbilical region does not heal well. On the contrary, the temperature is insufficient, the embryo growth and development is delayed, and the incubation is delayed.

2) If the temperature is too low, the hatchability will be reduced. If the temperature is below 224, all embryos die after about 30 hours.

Third, temperature control.

The temperature control should be based on the temperature requirements of the embryo, the incubation method, and the incubation method. For example, the constant temperature incubation method is used to incubate in batches, and the incubator temperature is controlled at the temperature of the incubator; The whole batch was incubated by variable temperature incubation method for 1-7 days. The temperature is 38 days, days, days.

The room temperature of the incubation room is best controlled at 22 26. This results in better hatching results.

Yes, this is because when incubating eggs, you must pay attention to the appropriate temperature, otherwise it will affect the hatching effect.

It has an impact on the quality of the eggs, and if the temperature is particularly high, the quality of the eggs can be particularly good, and the chicks may hatch.

Temperature has a very big impact on the quality of eggs, because the temperature of hatching eggs determines whether an egg can hatch, so the impact is still relatively large.

I think the temperature at which the eggs are hatched has an impact on the quality of the eggs, because the relationship between the two is very close, and there is a scientific basis for this, so we must look at it sensibly.

Eggs need to be kept humidity during the hatching process, and under normal circumstances, the humidity under the belly of the hen is a very suitable level. According to this criterion, it is also achieved in the process of electric incubation.

If necessary, maintaining a good humidity can make the skin of the egg a little better, which can make the hatching faster.

Hatching eggs needs to pay attention to humidity, if the humidity is not up to standard, it is difficult to succeed in hatching, and it is especially easy to waste eggs.

Yes, so that the eggs can be better hatched, prevent problems with the eggs, and improve the success rate.

1. High humidity has an impact on chicks. When incubating, it should be noted that humidity plays a very important role in the whole incubation process, if the humidity is insufficient, it will lead to embryonic stickiness, hatching difficulties, too high humidity, it will lead to poor yolk, poor physique, easy to die. The appropriate humidity must follow the principle of high at both ends and flat in the middle, that is, the humidity should be maintained at 60%-65% in the early stage, 55%-60% in the middle stage, 60%-68% in the later stage, and 70%-75% in the hatching period.

2. During embryonic development, temperature and humidity will affect each other, low humidity is required when the temperature is high, and high humidity is required when the temperature is low. Modern incubators can fix the right temperature for optimal incubation and loss rate, but it cannot fix the humidity, so the humidity can only be adjusted automatically. If you want to increase the humidity during the last 2 days of incubation (20 or 21 days), then you must empty it and lower the temperature.

3. The relative humidity of the incubator must always be kept at about 53-57%, and it must be increased to about 70% when the hatch begins. The relative humidity in the air can generally be measured by a thousand wet bulb thermometer, which is covered with a water-wet gauze strip on the ball part of the ordinary thermometer, and when the air flows through the ball and the gauze strip, it will produce a customized cooling effect due to the evaporation of water.

Very creative ideas ......

It is actually feasible to hatch eggs in warm water. Moreover, the warm water incubation method has simple equipment, easy operation, uniform egg temperature, low cost and good incubation effect.

Key points: 1. Egg selection and disinfection. Good eggs guarantee hatchability.

2. Water temperature control. The water temperature was not well controlled, so I had to wait for the boiled eggs.

Here's how:

1. Preparation of incubation equipment. Choose a house that is dry and warm, the size of which depends on the size of the hatchery. The outer layer is 150 cm long, 80 cm wide and 28 cm high.

8 egg trays are placed on each layer in the box, and sawdust (sawdust) is prepared as a thermal insulation material and covered with gauze and quilt to adjust the egg temperature.

2. Choose eggs. Choose eggs that have been stored for no more than 7 days, have a moderate size, normal egg shape, obvious egg ends, and a clean surface without cracks.

3. Disinfection and preheating. Before hatching, the eggs are placed in the1. Soak in the aqueous solution of Xinjieerfen for 3 minutes to kill the harmful microorganisms on the eggshell; The eggs are then pre-warmed at 36 to 38 for 6 to 8 hours.

4. Incubation temperature and humidity. Add hot water to the box and increase or decrease the thickness of the covering (gauze, single cloth, quilt) to adjust the egg temperature. The egg temperature is 7 days after the beginning of incubation, changed to 8 days later, 17 to 19 days to drop, 20 days to the end of hatching for the incubation period of 55% 65%, and increased to 65% 70% at hatching

5. Shine on the eggs. Before incubation, the eggs were strictly taken care of, and the unqualified eggs were eliminated, and the first eggs were taken three times on the 6th, 11th and 17th days of incubation.

6. Turn the eggs. Turning eggs at an angle of 80° is the key to improving hatchability. During hatching, the eggs can be turned once at an interval of 8 to 12 hours, and the eggs can be stopped after being moved into the hatcher tray 3 days before hatching.

7. Hatching. In the later stages of incubation, the embryonic lung function has been formed and sufficient oxygen is needed, so there should be some space between the mulch and the eggs and the frequency of ventilation should be increased.

No. In the process of development, the embryo must be exchanged with gas, especially after the 19th day of incubation (12 hours earlier in summer), the embryo begins to breathe in the lungs, the oxygen demand gradually increases, and the carbon dioxide emission gradually increases. At this time, if the ventilation is poor, it causes serious hypoxia in the incubator, even if the chick breathing volume is increased by 2-3 times, it still can not meet its need for oxygen, and the result inhibits the middle of cell metabolism, so that the acidic substances accumulate in the body, and the partial pressure of carbon dioxide in the tissue increases and metabolic respiratory acidosis occurs, so that the socks lead to a decrease in stroke volume, myocardial hypoxia, necrosis, cardiac disorder and beating arrest.

If the ambient temperature is above 22, chicks can still hatch.

The main influencing factors for the development of chicken embryos in vitro are: temperature, humidity and ventilation. Whether or not chicks can hatch depends on the control of three conditions.

a) Temperature. The effects of high and low temperature on embryonic development are as follows:

1) Under high temperature, the embryo develops rapidly, the incubation period is shortened, the embryo mortality rate increases, and the quality of chicks decreases. The incubation temperature exceeds 42 and the embryo dies for 2-3 hours. After 5 days of incubation, when the hatching temperature reaches 47, all the eggs die within 2 hours.

After 16 days of incubation, the hatchability rate decreased slightly after 24 hours at temperature; At 43 hours after 9 hours, hatchability was severely reduced; At 3 hours or 1 hour, all embryos die.

2) Embryonic development is stunted at low temperatures, the incubation period is prolonged, and the mortality rate increases. The incubation temperature is last, and most of the embryos die inside the shell. The small deviation from the upper and lower limits of the optimal temperature has less inhibition effect on embryonic development after 10 days of incubation, because the self-temperature of the embryo and egg can play a proper role in regulating it.

In general, the incubator temperature must be maintained at 22-26.

b) Relative humidity.

The adaptation range of chicken embryonic development to the relative humidity of the environment is wider than that of temperature, generally 40-70%. Too low humidity causes too much water evaporation in the egg, which can easily cause adhesion between the embryo and the shell membrane and cause dehydration of the chicks. Too high humidity will affect the normal evaporation of water in the egg, the belly of the chick is large, and the silver positive umbilicus is not well healed.

Too much humidity and too low will have normal metabolism in embryonic development, which will adversely affect hatchability and chick health.

c) Ventilation:

Ventilation and gas exchange of the embryo: The embryo must constantly exchange gas with the outside world except for the first few days during development, and it strengthens with the increase of embryo age, especially after 19 days of incubation, the embryo begins to breathe with the lungs, and its oxygen consumption is more. Therefore, ventilation must be strengthened.

If the ambient temperature is higher than 22, the chickens can still hatch. The main factors influencing the development of chicken embryos in vitro are temperature and humidity. The hatching of chicks depends on the control of three conditions.

If these 6 wild eggs have been fertilized, they can be hatched by domestic hens. At a constant temperature of 37 5 and a humidity of 50 60, chicks can hatch in about 22 days. If you don't have a hen at home, you can buy a thermostat to hatch eggs, ** around 200 300.

In addition, whether the wild egg is fertilized or not, it can be illuminated by the beam of a candle or electric lamp, and if a piece has a black line (up close) and a small egg is held in the left hand, it is a fertilized egg. If there are no hatching chickens, it is very important that the incubation conditions are 37 5 ° and the humidity is 50 60.
