Ovoscopic process of chicken eggs
Not everyone knows what ovoscopy of chicken eggs is and how it works. To do this, they invented and invented a special device - an ovoscope, which can shine through eggs - ovoscopy of chicken eggs by day. Thanks to this translucency, the embryo can be examined every day. If, during incubation, deviations are visible in the embryo, depending on this, the incubation conditions are improved or changed. Eggs should be checked before laying.
Ovoscopy of chicken eggs by day
Why is this needed?
ovoscopy is the best way to understand if there are abnormalities in the fetus that cannot be seen by the human eye. It is by this method that specialists determine during incubationwhether there are cracks in the shell or a violation of the fruit itself.
If there are such changes or cracks, the egg is destroyed in case bacteria enter through the crack, then the bacteria can spread to other fruits.
The device itself is expensive, which is why most farmers do it yourself at home, and the device works perfectly.
How the whole process goes
In fact, ovoscopy is very easy. To do this, you need to take the egg in your right hand, then bring it to the device, and then turn the egg along the longitudinal axis. If you do it correctly and follow the instructions, then you can view all the drawbacks and drawbacks of incubation.
If all this happens at a poultry farm, then usually a specialist chooses a place for this process. And then there are a number of preparations for this procedure:
- eggs arrive in a special incubator and on special transport (after all, if you carry eggs by car or truck, the embryo can be damaged);
- after that, the incubators are taken to the place chosen by the specialist;
- then Ovoscopy of chicken eggs occurs during incubation;
- a specialist must necessarily disinfect all eggs;
- after that, the containers with eggs are sent back again.
Many farmers say that it is very important to ovoscopic hen eggs before incubation and to make the correct selection of healthy eggs in the early stages of the incubation period. An ovoscope will also work for this procedure. In this case, they look at how active the yolk is, its movements and location at that time.
If the egg has a uniform structure, then its yolk should be in the center, and its blunt end should look to the side, and without any exceptions. During the entire incubation period, such an inspection must be carried out at least 3 times, on major days. Also, you should know that you can take an egg out of the incubator for no more than 15-25 minutes. This is usually enough to know if everything is okay. There is a table of days on the Internet when you can and should check embryos for their development.
The first stage of verification
On the sixth day of the incubation period, you need to inspect the fruits for the first time.It is at such times that you can see the state of the fetus, at what stage all the circulatory systems that have already begun to form, and, of course, how the embryo itself is located. If it so happens that a chicken egg is not fertilized, then it has a very bright color tone, and the yolk resembles a dark spot, and the circulatory system is not visible, which means that it is absent.
The fading of the embryo is noticeable by its size, the picture, when illuminated, forms an oval fetus, which has uneven edges. The fact that the fetus has died becomes known on day 3 through the same blood cycle. If the fetus was developing well, then the circle would not be noticeable, and you would only see the blood system itself.
Therefore, the first ovoscopy is very important, it is at this stage of development that you understand which fruits will develop and which have already died. Dead embryos begin to smell and breed bacteria, which can get on healthy embryos, and they can die. So keep an eye on this for the first few days. In the photo and video on the Internet, you can see how a chicken egg should look like.
Possible defects
Sometimes this method is used to view duck egg... You can keep your table of days, where to write what date the check was, so as not to accidentally miss the next day of the check. Defects can be as follows:
- on the shell, you can notice many dark spots, which may mean that the fetus has either an excess of calcium, or, on the contrary, a lack (before bookmark double check for such a symptom);
- strange light lines may appear that will resemble cracks - this indicates that the shell is damaged;
- airspace may appear on either side;
- blood clots;
- if you notice dark spots, then it is mold;
- inside the egg there may be various foreign bodies (seen in the first days of the embryo);
- sometimes it happens that an egg has two or even more yolks (it immediately appears before the laying);
- if the yolk floats throughout the space or, on the contrary, stands still, most likely this means that it has dried up.
Eleventh day of "inspection"
This examination takes place on the eleventh days of the fetus's life. You need to choose a time of day that is not too hot or too cold. The room in which this procedure is to take place must have a stable temperature. The viewing system has not changed, they also bring an incubator with fruits, and a specialist examines them (there is a special camera). At such times, it is assessed what the allantois looks like. If the fruit grows well, then the allantois grasps the entire fruit and closes at the sharp end of the fruit. If this end is not visible, this means that the embryo does not mature correctly.
When you notice that the blood pattern of allantois is growing poorly, this may indicate that it is necessary to improve the nutrition of the fetus. Ovoscoping chicken eggs during incubation is a serous stage, which should only be dealt with by a specialist or a person with extensive experience in this matter, because if you select the eggs correctly before laying, this is one of the main steps to success. Also, the ovoscopy should be done by someone who can distinguish a healthy fetus from a deceased one. There are a lot of videos on the Internet that will help you understand how and when an embryo should look like.
Eighteenth day
Before the chicks hatch, a checkout procedure needs to be done to make sure that everything is fine with the fetus that will be born. If you look at the sharp corner of the egg, and if there is no bright spot, it means that the embryo is growing correctly. If you see a gap, this means that something is wrong with the chick, and it is developing incorrectly, it may not hatch or it cannot do it on its own. What is ovoscopy of eggs. Ovoscoping eggs by day is an important stage in the formation of the correct embryo. Checking on the right days gives you the advantage to monitor the development of the embryo.Before laying in the incubator, you can understand which embryos are missing something, in which case it is best to transfer the eggs to the middle of the incubator. Checking eggs every day is possible at home.
