Abstract

The method of chickens elimination, which includes the pre-incubation treatment of eggs by a physical factor, which means that laser radiation with a wavelength of 6328 A is used to increase chickens ’output and survival, They are with an average irradiation energy of 10 1-10 2 J / cm of the egg surface.

Description

four

The invention relates to the poultry industry and can be used for incubating eggs.

There is a known method of hatching chickens by exposing eggs to eggs before incubation with ultraviolet rays 1.

However, the known method is laborious.

There is also a known method of chick pulling, which is carried out by treating the eggs before putting them in the incubator with a magnetic field Csj.

However, the effect of an additional magnetic field is undesirable because it affects the magnetic sensitivity of the offspring, which plays a significant role in birds. It is known that even a weak magnetic field can change the sex ratio in the progeny, for example, U.Tolubey, and this shift can be quite significant, which is not always desirable. In addition, the treatment of eggs with a magnetic field requires special devices to carry out shielding of the staff, thereby violating the standard incubation technology.

The purpose of the invention is to increase hatchability to chick survival.

This goal is achieved by using laser radiation with a wavelength of 6328 A, which is carried out with an average irradiation energy of 10-10 J / cm2 of the egg surface as a physical factor affecting the eggs before incubation.

The method is based on irradiation of eggs with low-energy non-thermal coherent laser radiation of the visible range. For this, pre-selected by parameters and processed eggs, placed in trays, are placed on a conveyor system. Laser irradiation of eggs is performed on a setup that includes helium-neon optical quantum generators (lasers) with a density indicator.

laser radiation, measured directly on the irradiated surface, and the conveyor system for giving eggs for irradiation in standard trays, without violating the technology.

The best effect is achieved when using a laser with a wavelength of 6328 Au and an average irradiation energy of 10 2 J / cm. After irradiation, the eggs are incubated in the usual manner.

Example 1. A standard tray filled with 140 eggs is taken and irradiated with laser radiation of the visible range with a wavelength of 6328 A, with an average irradiation energy of 10 J / cm with an exposure of 5 minutes, then incubated in a massive manner.

PRI mme R 2. Take the standard tray, filled.140 eggs, and. irradiated with visible light with a wavelength of 6328 I, with an average irradiation energy of 10 J / cm with an exposure time of 5 min, then placed in an incubator.

Froze A standard tray filled with 140 eggs is taken and irradiated with laser radiation of the visible range with a wavelength of 6328 A, with an average irradiation energy of 10 J / cm with an exposure time of 5 minutes, then placed in an incubator.

EXAMPLE 4 A standard tray filled with 140 eggs was taken and irradiated with laser radiation in the visible range with a wavelength of 6328 A, with an average irradiation energy of 10 J / cm2 with an exposure time of 2 minutes, then the eggs were transferred to an incubator.

Example 5. A standard. Tract filled with 140 eggs is taken and irradiated with laser radiation of the visible range with a wavelength of 6328 A, 5 with an average irradiation energy of 10 J / cm with an exposure time of 2 minutes, then the eggs are transferred to an incubator.

Example 6. A standard tray filled with 140 eggs, 0, is taken and irradiated with laser radiation of the visible range with a wavelength of 6328 A, with an average irradiation energy of 10 J / cm2 with an exposure time of 2 minutes, after which yy is placed in an incubator.

In tab. Figure 1 shows the results of hatchability of chickens after the applied treatment of eggs with laser irradiation.

In tab. Figure 2 shows the results of growing the experimental and control groups of chickens to 30 days of age.

From tab. 2 it can be seen that safety was higher in the experimental groups (there were no large differences in safety among these groups) in comparison with the control by 4.95 and 4.79%, respectively.

The results of the development of internal organs in chickens at the age of 30 days are presented in table 3.

in the experimental groups, the living mass and internal organs were developed better than in the control.

On opening the chickens, there were no abnormalities in the development of the internal organs.

In the best poultry farms, the hatchability and survival rate of juveniles during the first week for chickens is 80-85%, for ducks - 60-65%.

The increase in hatchability and survival rate of the young is even 1% in

the whole country gives a great economic effect.

The proposed method allows to increase the percentage of hatchability and survival rate of the young compared to the control batch by 3-4%. The use of laser irradiation is also convenient in that it allows mass treatment of eggs without disturbing

general technological cycle. In addition, the irradiation is directed in very small doses, so that there is no need for shielding the operating personnel.

In addition, irradiation contributes to an improvement in the duration of the viability of the embryo in the hatching egg.
