The invention relates to the field of poultry and can be used on poultry farms to increase the hatchability of Chicks, including from eggs obtained from chickens to the late timing of egg production, as well as for the subsequent formation of stable immunity birds.
In terms of industrial production are important issues: increasing output conforming of young birds from hatching eggs of different quality; correction of immune disorders of different etiology in the early post-embryonic period and in subsequent stages of growth; the formation of a homogeneous immunological relationship of the herd; the formation of a stable post-vaccination immunity, increasing the safety of birds.
There are various physical methods of influence on the egg with the purpose of improvement of incubation, and Chicks to stimulate the immune system.
Known radiation method of processing eggs before placing in the incubator to increase hatchability (U.S. Pat. EN 2120209 IPC6AC 41/00, publ. 1998). In accordance with this method before laying eggs in the incubator they are subjected simultaneously to heat in the temperature range 37-40°C for 1-5 h and processing of x-ray and gamma radiation at doses of 10.5-15 happy at dose rate of ionizing radiation 1-10 rad/h, However, described the first method of processing eggs refers to the stress modalities, the effect is instantaneous and does not use any positive effects on embryos at the last stages of incubation, where the risk of death is high.
The known method of chick-based processing of eggs before placing in the incubator several sources of radiant energy in series: radiation intensity discharge lamp DMESG-500 with a wavelength of 630-650 nm, the average dose on the surface of eggs 23.1 erg in the exposition 15, light helium-neon laser of wavelength 632.8 nm, power density on the surface of eggs 50 mW/cm2in the exposition of 2 and UV lamp wavelength 185-400 nm, the average dose on the surface of eggs 20 mark in exposure 5 C. Such effects on the embryos of birds before placing in the incubator exercise four to five times with an interval of 5 minutes resulting In reduced fetal waste by the number of "false" fertilized eggs, blood rings, frozen embryos and sadahiko, as well as substandard, weak Chicks and crippled, while the output of viable offspring is provided above the control at 8-12% (U.S. Pat. No. 2053665 IPC6AC 67/02, AK 45/00, publ. 1996). The disadvantage is technologically sophisticated implementation of this method for application in industrial poultry farms, requires multiple handling of eggs before laying (4-5 times), but there is no damage to the Oia at the subsequent stages of embryonic development of birds, where the risk of death is high.
A method of processing eggs of low-intensity electromagnetic radiation of millimeter-wave range, described in the article (Burdekin "Irradiation of eggs increases hatchability", Ukr. "Poultry" No. 4, 2003), which describes a method of stimulation of the embryos in the eggs of chickens cross "Smena-2". Before placing in the incubator eggs were processed once the EHF radiation (emission frequency 53,53 GHz). The irradiator installation for implementing the method is executed in the form of a horn with an insulating nozzle that specifies the distance to the irradiated surface. The density of irradiation on the aperture of the horn - 10 mW/cm2. Irradiation was performed for 30 s According to the results of incubation investigated waste of incubation. The increase in output of young animals by reducing the number of dead embryos in the first days of incubation. The disadvantage of this method is that it does not use the positive influence of irradiation on the subsequent stages of embryonic and post embryonic development of birds, where the risk of death is high.
The known method of increasing the viability of poultry for Newcastle disease by increasing the immunity of the bird, which is selected as the closest analogue (published application No. 2001128822, IPC7AC 45/00, A61N 5/08). Prototype method is that consistently carry out the heating of chicken embryos SV is the volume of the gas-discharge lamp DMESG-500 wavelength 680-650 nm, the average dose on the surface of eggs 23.1 erg in the exhibition 15; processing radiation of helium-neon laser LGN-104 a wavelength of 632.8 nm, power density of the optical flow on the surface of eggs 50 mW/cm3in exposure 2, a mercury-quartz lamp CES-400 wavelength 400/185 nm, the average dose on the surface of eggs 20 mayor/h and two germicidal lamps PDR-15, the wavelength 254/800 mm, rated power on the surface of eggs 15 watts exposures to 5 C. Impact of exercise four times with an interval of 5 minutes Processing of hatching eggs is carried out before incubation and on the 6th, 12th and 18th day of incubation. In the same modes handle day-old Chicks before their immunization vaccine "Bor-74 VGNKI" against Newcastle disease. Prototype method provides repeated exposure to radiation on embryos of chickens and a single impact on day-old Chicks, which increases the immunity of the bird, but only at an early stage of development.
However, this method does not provide a stable immunity during the whole technological cycle of breeding birds, since it is known that for the formation of stable immunity requires repeated exposure to stimulating factor (Alikin US, Kirsanov CENTURIES, Klimenko V.P., Ponyhof VA, Chemetov E., Yushkov YG Methodology of immunomodulators in industrial poultry farming // Bio. -2004. - No. 4, 5, 6; B. Birman, I. Gromov Immunodeficiency birds. - Minsk: - 2001).
The problem solved by the present invention, is the formation of a stable immunity birds at all stages of the technological cycle of growing and improving the hatchability of Chicks, including from eggs obtained from industrial poultry late egg production.
This technical result in a designed way to enhance immunity of the birds in the conditions of industrial production, as well as in the way the prototype is achieved through the processing of eggs and Chicks of low-intensity electromagnetic radiation (EMR).
New in the developed method is that first before placing in the incubator, single irradiation hatching eggs EHF EMR power density on the surface of the eggs of the order of 0.3 mW/cm2the exhibition 3-6 minutes, then in the same modes carry out the irradiation of day-old Chicks to the first vaccination and during the next process cycle cultivation conduct subsequent periodic exposure of chickens radiation in the same mode every 6 days, but not later than 72 hours before the next vaccination.
It is expedient in the particular case of the method for irradiation of eggs and Chicks to use low-intensity EHF EMR with additional low-frequency modulatio is in scan mode from 1 to 10 Hz.
The formation of stable immunity birds at all stages of the technological cycle of cultivation developed method can be explained as follows.
One of the properties of low-intensity electromagnetic radiation EHF is improving immunity by raising nonspecific resistance of the organism due to the synthesis of biologically active substances immunocompetent cells of the body (Betsky OV, Kislov V.V., Lebedev N.N. Millimeter waves and living systems / "science press", M., 2004 pp.96-97, 116-117) in Addition, numerous clinical studies of the immunological response of the body to radiation EHF give reason to consider the influence of this factor for the formation of stress reactions, which contributes, in turn, the best adaptation of the organism to external influences (see ibid.).
Problem solving in industrial production is achieved by repeated exposure to a certain dose of low-intensity electromagnetic radiation EHF at different stages of embryonic and post embryonic development of birds. Processing of hatching eggs before placing in the incubator is used for stimulation of embryogenesis and reduce the destruction of embryos in the first 48 hours of incubation; the handling of day-old Chicks up to about what edenia first vaccination is achieved by reduction vaccination stress, that contributes to a more effective vaccination; treatment birds at the subsequent stages of the technological cycle of cultivation can reduce the negative impact of several factors (immunotropic viruses, worms, age immaturity of the immune system, technological stress etc), leading to the development of persistent immunopathological States and form a strong immunity (I. Bolotnikov, Makieva B.C., Oleinik E.K. Stress and immunity in birds. - L.: Nauka, 1999. - 118 S.; Voronin Y.S., Petrov A.M., Gray M.M., Gavrilov D.A.

The invention is illustrated by examples.
Example 1. We used hatching eggs obtained from chickens meat (Baros 123) and egg (ISA Brawn) crosses, various terms of egg production. Experimental and control group which is granted according to the principle of analogues. For group 1 (cross Baros 123) experimental and control on 816 eggs, 2 groups (ISA cross-Brawn) experimental and control on 816 eggs. Incubation was carried out with observance of the standard process parameters in industrial incubators CSI-f-45. Biological control in the course of the incubation, the analysis of the dynamics of mortality of embryos by periods of incubation and evaluation indicators output was carried out according to the standard technique (Bessarabov B.F., Sadchikov HE Embryonic and postembryonic diseases of poultry. Mgaweb them. Ceasaria, Moscow, 2003).
Egg experimental groups were treated with low-intensity EHF EMR for 10 hours before putting in the incubator. The irradiation was carried out by the generator millimeter radiation (EHF EMR) PORT-ELM/NN (frequency 53,56 GHz) with a power density of 0.29 mW/cm2on the surface of eggs in exposure 3 minutes. Incubation results presented in table 1.

It is found that the treatment of hatching eggs in a production environment can significantly increase the output of young animals in the experimental groups compared with control, non-irradiated groups. So, the General conclusion in the experimental and control group were, respectively, 85% and 81% (cross Baros 123); 80% and 75% (ISA cross-Brawn). The increase in total output in the experimental groups is associated with a significant decrease in the death of embryos at early stages of embryonic development (within the first 48 hours of incubation). In the later stages of incubation parameters in experimental groups did not significantly differ from the control.
Showed a significant increase in the output of the certified juveniles from irradiated eggs. Conditioning of the young animals in the experimental and control group were, respectively, 83% and 79% (cross Baros 123); 80% and 75% (Isa cross-Brawn).
Simultaneously examined the effect of EHF EMR on the conclusion of the young from hatching eggs obtained from hens of different timing of egg production cross bars 123. Experimental and control groups were formed on the principle analogues. For group 1 (age hens 259 days), group 2 (age of ness is to 336 days) for 3 groups (age hens 405 days) 136 eggs in the experimental and control groups. Processing was carried out according to the above method. The results of the output are given in table 2.

It is established that the effect of low-intensity EHF EMR contributes substantially improve the structure of the output is squared away young from eggs low hatching quality, retrieved from the birds to the late timing of egg production. So, conforming young cross Baros-123 in the experimental and control group were, respectively, 88% and 84% (age hens 259 days); 85% and 77% (age hens 336 days), 77% and 72% (age hens 405 days).
1. Processing of hatching eggs of low-intensity EHF EMR has a positive effect on embryonic and early postembryonic development of birds:
- leads to a significant decrease in the death of embryos at early stages of development. The death of the embryo within the first 48 hours of incubation decreases in 2 times;
- the chick is increased by 2-4%;
- significantly increases the output of conditioned calves 4%.
2. Irradiation significantly increased output conforming young from eggs low hatching quality obtained from birds late egg 5-8%.
3. Processing method of hatching eggs of low-intensity EHF EMR is one of the promising directions in the use of bio-stimulating properties of this radiation in industrial poultry farming. This is also due to the possibility of developing a simple technological solutions for the implementation of the method in scheme standard preincubation events.
Example 2. From Chicks day old ISA cross-Brawn were composed of g is uppy equivalents (experimental and control) 160 goals in each. In the experimental group consisted of Chicks obtained from eggs treated with EMR EHF before placing in the incubator. The control group consisted of Chicks obtained from raw eggs. The chickens in the experimental group (160 heads) were treated with low-intensity EHF EMR 10-12 hours after the conclusion, before the first vaccination (Marek's disease and infectious bronchitis chickens) and transportation in the shop. In further processed poultry was carried out every 6 days, including 72 hours prior to vaccination and routine veterinary activities. The irradiation was carried out by the generator millimeter radiation PORT-ELM/NN (frequency 53,56 GHz) with a power density of 0.3 mW/cm on the surface of the object, in the exposition of 3-6 minutes.
Chickens of the control group (160 heads) processing of millimeter radiation (EHF EMR) were not exposed.
At 20 days of age the Chicks of the experimental and control groups were inoculated spray method live virus vaccine La Sota against Newcastle disease in accordance with the instruction on its application.
The formation and intensity of immunity against Newcastle disease were studied using the reaction of inhibition of haemagglutination (see table 3).

Found that the titers of specific antibodies in chickens from the experimental group were higher and ranged from 1:239 14 day before 1:56 am on day 56 after the first vaccination, the chickens of the control group antibody titers at the same time were 1:138-1:24. Dynamics of extinction intensity group immunity was also not the same. So in the experimental group tensions of group immunity on day 14 after vaccination was 100%on day 56 - 92%in the control group, respectively 92% and 72%. The results obtained are statistically significant (p<0,05).
1. The formation of post-vaccination immunity on the example of Newcastle disease in chickens under the influence of low-intensity EHF EMR is faster and more reliable.
2. High titers of antibodies (antibody titer of 1:16 and above) are retained for 60 days 90% of the total grafted pogol the vias. This allows to extend the time of revaccinate and avoid frequent antigenic stimuli (multiple vaccinations in a short period of time) of the immune system, which is of great practical value.
3. Method EMR EHF as a very simple and cost-effective can be implemented in any production technology poultry production without any breach of this technology.
