Is the bird eggs sold at the entrance of our school? Can it be hatched?

The eggs are very high temperature, and it is also heated and balanced. Do you think you can meet your requirements?

The necessary egg incubation process
Ifids in the late period of cold eggs can increase duck, goose incubation rate
duck, goose eggs with large volume, the unit weight of the unit is small, and the heat dissipation capacity is worse than that of chickens. Cool eggs must be used for a period. The specific method is as follows:
Is to incubate with 1 incubator, you should open the door twice a day, pull the egg plate from 18 to 24 days from the shelf for 2/3, and move the plate from 25 days to the out of the chicks. Two times the cold eggs are twice a day, and the egg sake is pulled out of the interval. If the egg temperature is too high, pull out the egg plate out of the machine and put it in the machine. Generally, the time of cold eggs is 30 to 40 minutes each time, and the specific time depends on the actual situation.
Is when using 2 incubators for incubation, incubation in A machine on the 1st to 15th day, temperature of 37, 7 degrees Celsius, 65%humidity, no cold eggs; incubation in the 16th to 26th day, temperature 37, 5, 5, 5 ~ 37, 7 degrees Celsius, 50%of the humidity, and the egg plate is pulled out of the machine regularly every day, sprayed with water twice, and after 26 days, the egg was moved to the chicks of the chicks of the armor.
In order to reduce the labor when the cold egg is, after the incubation 16 to 17 days, the method of strengthening ventilation can be used to discharge excess calories in the eggs and meet the needs of embryonic vitality.
The temperature and humidity conditions for poultry incubation period
. Temperature conditions
The temperature is the primary condition for poultry embryo development. Poultry embryo develops in different periods, and the requirements for temperature conditions are basically the same.
Chicken: The incubation period is 21 days. 38.5 ° C for 1 to 6 days; 7 to 14 days is 38 ° C; 15 days are 37.9 ° C; 16 to 21 days are 37.3 to 37.5 ° C.
duck: the incubation period is 28 days. 1 to 7 days is 38 ° C; 8 to 16 days is 37.8 ° C; 17 days are 37.5 ° C; 18-28 days are 37.3 ° C.
see: 30 days of incubation period. 1 to 8 days is 37.9 ° C; 9 to 18 days are 37.8 ° C; 19 days are 37.8 ° C; 20-30 days are 37.0 ° C to 37.3
° C.
. Humidity conditions
The humidity conditions are the basic guarantee for poultry to maintain embryo development. Poultry's requirements for relative humidity during different incubation periods are basically the same.
The relative humidity in the early stage of incubation is maintained at 60 % to 70 %; the relative humidity in the middle and late stages is maintained at 50 % to 55 %; the relative humidity during the shelling period is maintained at 65 % to 70 %.
The important factor affecting the incubation
In the development of chicken embryos, gas exchange must be performed, especially after the 19th day of the incubation (12 hours in summer), the embryo began to breathe lung, and oxygen needs to be oxygen. The amount gradually increases, and the amount of carbon dioxide discharge gradually increases. At this time, if the ventilation is poor, it will cause severe hypoxia in the incubator. Even if the volume of chicks from the shell increases 2-3 times, it will still not meet the needs of its oxygen. In the accumulation of the tissue, the increased voltage of carbon dioxide in the tissue increased metabolic respiratory acid poisoning, which caused the heart to decrease, and the cause of myocardial hypoxia, necrosis, cardiac disturbance and beating arrest occurred. The oxygen consumption of the entire incubation period of each embryo egg is 4-4.5L, and 3-3.5L of carbon dioxide is discharged. The test proves that the oxygen content in the incubator decreases by 1%, then the incubation rate decreases by 5%; when the carbon dioxide content of surrounding embryo eggs must not exceed 0.5%, and the carbon dioxide reaches 1%, the embryo development is slow, the mortality increases, and the
has increased. The normal oxygen amount in the air can be maintained at 20%-21%. Therefore, the key to ventilation is to try to reduce the concentration of carbon dioxide around embryo eggs, and the effect of ventilation and ventilation is related to the structure of the incubation equipment, the building design of the incubation hall (room), and the inside and outside environment of the incubator. The factors that affect the incubation rate are the first, followed by ventilation. Why do many books follow the temperature, humidity, ventilation ... sorted instead of temperature, ventilation, humidity? The reason is simple. The method of artificial incubation is imitated in the mother poultry to hold eggs. The mother poultry is selected in a dry place, and the birds are mostly on the trees. The number of incubation is not much, and the wind is too much. For more than one, this is important. Moreover, many experiments have proved that water -free incubation does not affect or does not affect the incubation rate in previous years.
The old -fashioned incubators mostly have disadvantages such as a small number of fans, low speed, and unreasonable distribution. Not only are the breathing incomplete, there are dead ends, but also the heat source and calories cannot be sent to everywhere. Big. To this end, a new incubator should be carried out or replaced.
In important issues that have been ignored during the incubation process
The summary and reasonable formation time according to the shell pecking during the fall. Under the premise of incubation technology, the difference in the storage period of egg production and
will also affect the neatness of the shell. In order to increase the neatness of the shell, in general, the planting
eggs at the beginning of the egg, the eggs with more than 7 days in the storage period should be incubated 6 hours in advance. When the egg is up to the incubation temperature to the set value. Potassium permanganate with 28ml/m3 formaldehyde and
14ml/m3 fumigated for 20min (or 30 seconds of disinfection lights). (Avoid the embryo eggs that have been incubated for 24-96 hours.) Those who are incubated in the batch will throw 28ml/m3 formaldehyde of 28ml/m3 in the incubator and potassium permanganate of 14ml/m3. Essence
This: hatch to the 19th day, pick out the dead tire. Put the embryo eggs in the upper and lower positions of the incubator to the back and rear position of the chicks
. After falling, clean the incubator in time, fumigate with 46ml/n3, smoked for 20min.
The smoked chicken: Observe the chicks, when the chicken starts, use 25ml/min formaldehyde Men let it evaporate naturally and disinfected.
In picked chicken: When most chickens come out of the shell, 5 % of the back of the neck will start picking the chicken when the pills are not dry. Details, pick chicken
seedlings in time after picking chicken. Distinguish between healthy and weak.
This storage: After the chosen chosen, the chicks are well ventilated, the temperature is 25 ° C, and the temperature is 50 % suitable, and the dehydration is sprayed with water according to the parking time.
Is sweeping stalls: After the chicks are over, pick out the hair eggs, check the number and record it in detail, and then completely clean the chicks. In the above -mentioned
In the main points of the operation, the action should be light, stable, and fast.
Is when the electric incubation work, what measures should be taken when encountering a temporary power outage
The length of power outages should be based on the power outage season. Take corresponding measures.
(1) Early spring, the temperature is low, and there is no heating equipment in the room. The room temperature is only (5 to 10 ° C). At this time, the inlet and outlets of the incubator are generally closed. If the power outage time is within 4 hours, there is no need to take any measures. If the power outage time is relatively long, you should increase the
warm equipment indoors, and quickly increase the room temperature to 32 ° C. If there are also embryo eggs that come out of the shell, but the number is not large, the treatment method is the same as the above. If you have a lot of eggs
The number of eggs, you should pay attention to prevent the central area and the top layer of embryo eggs on the top of the top. When you find that the egg temperature is hot, you can adjust it.
(2) The temperature exceeds 25 ° C. The egg embryo in the electric incubation is within 10 days. There is no need to take any measures when the power outage is out of power. The temperature in the machine decreases a little. It is estimated that the temperature of the top layer of eggs on the top will drop by 2-3 ° C (depending on the size of the visual embryo). , Keep it at a non -temperature. If the cooling time in the freezer is extended, the door will be closed after it decreases above 3 ° C. , Adjust the disk, pay special attention to prevent the egg temperature from high.
(3) When the temperature exceeds 30 ° C, if it is an early egg, you can not take measures. If it is an egg in the middle and late period, you must open the door (the air intakes are opened at the same time), and the air intakes are originally opened). Reduce the temperature in the machine below 35 ° C, and then close the door (the egg in the middle) or the door is not tightened as appropriate, leaving a seam of the later eggs), check the egg temperature on the top of the top once a few hours per hour. If the power outage time is long, or the power outage time is not long, but there is a regular temporary power outage (such as 2, 3 hours) almost every day, you must be daily or every 2 days at as appropriate. In order to make up for the low temperature caused by the daily power outage (especially the areas with more power outages), the incubation temperature should usually be about 0.28 ° C than the normal temperature standard used). In this way, despite the short -term power outage every day, the chicken embryos can also be gone in the twenty -first day.
The stinky eggs during the incubation process are prone to stinky eggs during the incubation process. The stink eggs are very harmful, and improper treatment will seriously affect the incubation benefits. Below, a brief description of the four aspects of the dangers, formation, treatment and prevention of stinky eggs is described for reference. First, the dangers of stinky eggs. Stinky eggs not only pollute the environment of the environment, but also endanger the health of chicks. Its harm mechanism is mainly: the content of the stink eggs contains a large amount of Greenworm. Once the smelly egg bursts, it invades the normal breeding eggs
to reproduce, causing these normal developmental egg embryos to die and stink, becoming another odor, becoming another odor Egg pollution sources, pollute other eggs, form a vicious circle. In addition, the stink eggs contain a concentration of hydrogen sulfide gas, which emits in the incubation room, affecting the breathing metabolism of the embryo. If the indoor hydrogen sulfide reaches a higher concentration, it will cause embryo to suffocate death, which will affect the chick rate. Second, the formation of stinky eggs. The formation of stink eggs is the result of bacterial infection eggs. These bacteria are mostly fake monocylococcus, mainly Greenland. The main reasons for the formation of the stink eggs are the following aspects: 1. Due, feet, feet, feces, pads and chicken house equipment pollute the eggshell. As the eggs are produced quickly, the content is shrinking, attached to the eggshell, attached to the eggshell The
Iladia bacteria invades the eggs and reproduce. 2. Broken eggs, crack eggs and thin shell eggs, bacteria can easily invade the eggs. 3. Due to the explosion of the stink eggs, the seeds of the same machine incubated. 4. Eggs that are not disinfected by incubation utensils are not strictly disinfected. Third, the treatment of stinky eggs. During the incubation process, if the smelly eggs are found, and the contaminated seed eggs should be gently removed out of the incubation plate, removed the breeding eggs that have not been contaminated, and code in another disinfected cleaning disk, and inserted into the incubator. The stink eggs and polluting eggs are installed into the seal container, and the incubation room is cleared; the incubation plate is soaked for 24 hours with 5% hydrochloric acid, and then was completely cleaned and then used at
. Fourth, the prevention of stinky eggs. 1. In order to prevent breeding eggs from being polluted, picking eggs in time, it is best to pick up eggs every half an hour. 2. Strictly select planting eggs. Dirty eggs, broken eggs, crack eggs, and thin shell eggs cannot be incubated. Wipe the eggs with wet wet cloth. 3. Do a good job of breeding eggs. After picking out the eggs from the chicken coop, immediately use potassium permanganate and Forma to fumigate for 20 minutes and send it to the egg library. 4. Follow the eggs, and you should find and remove the stinky eggs and crack eggs in time when you fall into the plate. 5. Do a good job of cleaning and disinfection of incubation equipment and incubation room. Incubation utensils such as eggs
, soaked with medicinal solution should be used to remove dirt such as egg skin, egg liquid, tire dung, mucus and other dirt. The chick must be completely disinfected once. The ground floor of the incubation room insists on sodium or 10%every two days to disinfect Surl.
One of the methods of chicks and male and female-turning anal
(1) The best time to identify chicks about 12 hours after the shell is out of shell. Because at this time, the most significant difference between the male and female reproductive protrusions
, the chicks are easy to grasp, the chick's belly is full, and it is easy to open the anus; N difficulty, and the anus is not easy to open. Do not exceed 24 hours after the shell is out of the shell.
(2) The identification of the chicken's mating organ is degraded, and there is a small protrusion in the center of the lower end of the chick's cloaca, called reproductive protrusions;
The oblique direction is eight -shaped, called the eight -character folds; reproductive protrusions and eight -character fixture constitute the reproductive bulge.
This Kwong Cowing Cress opening sees reproductive protrusions, reproductive protrusions, tight, elastic, shiny, bright contours, finger compression is not easy to change
; The residual reproductive protrusions are mostly atrophied, soft, soft, non -lustrous, and fingers are prone to deformation.
(3) The operation method holds the chicks with the left hand, holding the chick neck with the middle and ring fingers, and the ring finger and the little finger hold the chicks with both feet. Pay attention to the lightness and do not damage the chicks. Put your left thumbs close to the abdomen side, press the abdomen to discharge the abdomen, and then hold the side of the anus with your right thumb and index finger. The left thumb is matched with the left thumb and squeeze it gently to open the anus. Then observe under strong light. (Sunlight Excerion)
This The relationship between the humidity of shallow eggs and the incubation is extremely closely related to the incubation rate. In recent years, some scientific and technological workers in my country have been revealed by the freshman science "bionicism", and
have proposed that the electric incubator does not add water and does not control wet incubation. They believe that if the temperature is appropriate, the incubation rate of no water incubation has not changed much. For this doctrine, people have always been controversial. So, is there necessary for incubation production? In response to this problem, I talk about my opinions from a practical perspective, combining my work practice.
. The weight of the planting egg
is composed of most of the eggshells and contents, and its moisture accounts for about 65%. This shows that eggs are closely related to water during the incubation. Whether it is incubation, no water incubation and natural incubation, the weight of the egg does exist, and the reason for the loss is:
(1) During the development of the embryo, the product of the metabolism with metabolism is from the eggshell by the eggshell. Empty pores.
(2) The existence of poor pressure inside and outside the eggshell spread a large amount of water inside the egg to the outside of the egg shell.
(3) In order to form sufficient gas chamber so that the embryo can breathe and the chick pecking the shell.
(4) Maintain the water content in the newly hatched chicks as the same (about 67%)
Therefore, during the incubation process, the embryo is also more sensitive to humidity. If the water is lost too much, it will cause the embryo to develop too fast. The energy that is not used in use is used, which will cause dehydration, that is, "sticky glue". If the water loss is too small, the water produced during the metabolic process will drown in the embryo,
is the "water embryo". According to the experiment, from the top to the shell, the loss of moisture accounts for 12 or 6%of the fresh eggs, and the weight of the breeding eggs of different ages is different. Early period (1 ~ 10) average 0, 58%~ 0, 64%per day, and the average daily (10 ~ 16) is lost 0, 63%~ 0, 67%per day, and the average of 0, 57 in the later period (16 days to the pornography) %~ 0, 63%. In order to solve the problem of different weights, it is necessary to adjust a certain humidity in the incubator.
. The practicality of incubation
The relationship between temperature and incubation, the "bionic school" also pointed out in the proposal not controlling wet incubation method. Moisture still requires a certain amount of humidity. And where does this part of the water come from? There is no water incubation in the incubator, but there is still a certain amount of water in the air. The air along the incubator into the ventilator into the machine to affect the humidity in the machine. The difference between incubation and no water incubation in water lies in the control of humidity. Adding water incubation is to rely on the temperature of the controller to regulate the needs of different embryo poultry embryos. The incubation without water is to achieve the purpose of regulating the humidity of the intranchimeter by controlling the humidity (outside the machine) by controlling the indoor humidity (outside the machine). Although the latter can obtain a good incubation rate like the former, it is difficult to regulate humidity. The former is easier, especially with the continuous improvement of the degree of automation of the electric incubation, and the influence of the external (outside machine) environment is becoming smaller and smaller. The latter, due to the influence of seasonal and regional factors, such as different humidity in the north and south, the humidity required for embryos of different dates is equivalent to the former, which is more difficult. If it is improper, it will not only affect the incubation
, but also seriously affect the quality of chicks. As far as most incubation conditions in my country's incubation plants are concerned, it is still difficult to solve this problem. Therefore, it is suspicious of its practical value.
. The promotion of electrical incubation
With the rapid development of the chicken industry, the capacity and power of the electric incubation continuously increased. From the perspective of energy saving, it is reasonable to consider that without water incubation
But compared with natural incubation, the conditions it can provide to embryonic development is different. For example, the temperature in natural incubation is adjusted by its sensitive lower abdominal cortex to reduce the impact of the changing temperature of nature on the embryo eggs. In the electrical corruption (incubation), in order to make the constant temperature in the aircraft, the large -diameter wind drum device seriously destroys the ability of the poultry egg to adjust the greenhouse itself. As the degree of electricity incubation is improved, it is less and less affected by the external environment, so it is complete with appropriate humidity.
In short, in the entire incubation production, although the humidity is not as strict as the temperature, but if there is a work attitude of "humidity indifferent", it will inevitably affect the incubation rate and even the quality of chicks. As long as we require different rules and regulations according to the humidity of the embryo of different embryos, and apply different humidity in different incubation periods, we can also improve the incubation rate and the quality of chicks while saving electricity and electricity. High economic benefits. -Chic Chicken-2002-1/2-17
The effect of the frequency of egg rollover on incubation effect
Peving is one of the necessary conditions for artificial incubation to obtain high incubation rates. The purpose of the egg turning is to change the position of the embryo, prevent embryo and the shell membrane, promote embryo movement, make the embryo heat uniform, neatly develop and good, help shellasses exercise, improve the blood circulation of amniotic fluid, and enable the blood vessel area and the ils in the middle and late stages of the embryo. The growth of chorionic membranes is normal, the "close" and "seal the door" are good, and the protein enters amniotic fluid for embryo absorption, and the newborn is qualified. Eggs can also reduce the loss of amniotic fluid, so that the embryo pecks the shell and out of the shell in a moist environment. The important role of embryonic development during poultry egg incubation is obvious. So how to operate the eggs, how to determine the angle of eggs and the frequency of egg turning, this has a variety of solutions and views in the incubation practice and many monographs. Generally, the eggs are leaning back and backward at the horizontal position or turning left and right through the machine type 45 °, duck eggs 50 ° ~ 55 °, and goose eggs 55 ° ~ 60 °. Everyone's view is consistent. At this stage, there are many controversy on the frequency of egg turning, and there are various views such as every 4 hours, 3 hours, 2 hours, and 1 hour.
