Eggs hatching: requirements, features, storage

Breeding selection has meant that a lot of species known to date hens almost completely lost maternal instinct.Because of this, there is a need in the artificial cultivation of day-old chicks.Thus, the hatching egg can develop without hen in a special incubator.Let's talk with you about what demands are such eggs, how to properly store and so on. N.

Egg weight and shell quality

Currently, an experienced breeder should determine the weight with an accuracy of one gram.It uses precise electronic scales.It is desirable to select the largest balls, due to a high content of nutrients that are essential for survival of the instance.But despite this, these stringent requirements somewhat mitigated to the eggs of meat hens, which is due to drop in egg production.

egg hatching should be well protected.The surest barrier - shells.An important indicator - the integrity of the structure.This not only provides protection from external influences, but also allows for the necessary heat and gas exchange processes.Thus, the incubation is strictly forbidden to take away or cracked eggs beaten copies.Firstly, they rapidly deteriorate, leading to the development of bacteria.Second, such egg from moisture quickly leaves, thus minimizing the chances of survival of an embryo.Furthermore, it is not recommended to select eggs irregular shape having scratch m. P. Defect.

Using candling

As noted slightly higher hatching egg should not have defects.But in the eyes of small scratches reveal quite difficult.Therefore, it is best to use candling.This device, which is very bright and allows you to observe the smallest defects in the egg.As a general rule, you should immediately reject items damaged because of them get healthy offspring is almost impossible.

But it so happens that some of the eggs are of great value, so throw them out of the cracks or scratches are not very desirable.In this case, it makes sense to seal the crack starch-based glue.Pay attention to the marbling on the shell, which shows that from such eggs are unlikely to hatch healthy chicken.The problem is the low level of development of the embryo, which is not time to develop for 3 weeks.It is important that the egg hatching was an air chamber, which is responsible for the storage time.But the candling area is visible as dark spots.

About disinfect eggs

Almost all copies are pathogenic microflora.If it is not removed, the fungus or bacteria can penetrate and damage the embryo.To avoid this, you must disinfect the surface.If we talk about industrial scale here used formaldehyde vapors.Take an enamel bowl and pour it in about 30 ml of formalin and water.Next is added the same amount of sodium permanganate.All this is mixed and placed in a special chamber where the eggs are already prepared.As a result of the chemical reaction produces steam, which destroys all pathogens.Such amount of the mixture is sufficient to handle the camera 1 square meter.The disinfection procedure must proceed at a constant temperature of 37 degrees Celsius for an hour.Of course, besides this, broiler hatching eggs may be treated with 1% iodine solution, 3% sodium chloride and m. N. Let's go on.

hatching eggs of chickens: retention rules

Here it is imperative to observe the optimum temperature and humidity.According to studies, it is best to maintain a temperature of 18 degrees Celsius, since it is the largest young hatchability.The relative humidity in this case must be at least 85%.It is desirable that between laid eggs and laying it did not pass a lot of time.This is due to the fact that it begins to age and thus lose weight.Hatchability somewhat deteriorated, partly because of lost water from the protein.Permissible weight loss - no more than 0.2% of the total weight.Based on the foregoing, it must be said that the broiler hatching eggs, quail and other birds must be kept outside the incubator no more than 6 days.When the time hatchability of offspring drops sharply.Therefore, the productivity of the economy, too, will get worse, so do not forget about it.

about how you need to lay the chicken egg hatching

Most experts say that lay eggs directly into an incubator should be in the evening.This is due to the fact that in the morning can be chosen dried, i.e. unusable chickens.But despite this, you can perform this procedure when you want.It is important to choose the same weight eggs.This is because the large eggs in the incubator must be greater than the medium and small.At the same time you need to consider before laying the temperature drop.If storage is carried out in a cold room, you need to put the eggs in a warm room, thereby avoiding large evaporation.Tab must be in an upright position, and if the tray is not completely filled, then the eggs bonded metal strip.This is to ensure that the eggs were in place during turning.

Conclusion

Do not forget that in the incubator is necessary to observe a specific microclimate.This moisture, which must be at least 75%, and well ventilated.According to statistics, one egg consumes approximately 4 liters of oxygen and releases into the environment 3.5 liters of carbon dioxide.That is why the forced-air ventilation is a must attribute.This requires hatching eggs quail, chicken, geese and other birds.Remember that wet bulb temperature has to show not less than 29 degrees and dry - about 37. After about 6 days of incubation, you can watch the network of blood vessels.Thus itself the embryo is not yet visible.Him you will notice about the 11th day of development.Well, in principle, and all that can be said about how to store eggs for further incubation.
