The invention relates to agricultural production, particularly poultry. The invention aims to improve the hatchability of young poultry.

There are ways to encourage birds by preincubation handling eggs coherent radiation emitters (lasers) ("Method of biostimulation poultry" RF patent No. 2101939 C1. - Publ. 20.01.1998), as well as the integrated effect of discharge lamps, lasers and chemical stimulants ("plant for complex processing of hatching eggs of radiant energy by the RF patent №2265999 C2. - Publ. 20.12.2005 and Method of stimulation of embryonic and early postembryonic development of poultry" RF patent No. 2262228 C1. - Publ. 20.10.2005). The disadvantages of this method is the increased energy consumption, the use of emitters with low efficiency, large consumption of materials and dimensions of the units.

The essence of the invention lies in the fact that carry out the irradiation of eggs before laying on the incubation of electromagnetic radiation is unpolarized, incoherent polychromatic source, emitting in the range of 250-310 nm. The processing time is from 0.1 to 30 seconds, dose - 50-3000 MJ/m2. The application of this method allows to increase the hatchability of eggs by 4-9% and increase their innespace the activity. The method is easy to learn any practical and scientific worker associated with poultry.

The possibility of practical implementation of the method is confirmed by examples.

Example 1

To select the spectral characteristics of processing eggs need to know their optical properties. Conduct the experiment for the determination of the spectral coefficient of the reflected radiation. In the shortwave region of the spectrum (shorter than 400 nm) observed luminescence expressed in excess of its share of the reflected radiation over 100%. Then, in the range of 400...450 nm decreases and the decrease proportion of reflected radiation to 77...82%, after which it increases to 86...91% and remains relatively stable until near infrared range. For measurement of luminescence spectra and radiation, it is exciting, as the most important characteristics, spend experience on an FLUORAT-02-PANORAMA.

Measure the spectral characteristics of the excitation and luminescence belokolonny hatching eggs cross parent flock "Hisexs white". The results are shown in the drawing, it is obvious that there are two maximum absorption of the exciting radiation wavelength with λ<180 nm and longer wavelengths (λmax=285-290 nm). Fluorescent radiation excited from the first peak has its maximum at the wavelength of 231 nm, and the WTO is on high 337 nm. And the first maximum of the luminescence expressed more clearly.

From the analysis of the measured results, the conclusion must be conducting research on the impact of the spectrum of radiation on hatching characteristics of eggs in the range of their luminescence.

Example 2

To study the effect of radiation range 250...310 nm on incubation results in CJSC "Primorskoe" (Smolensk region) conduct an experiment using hatching eggs chicken parent stock of cross Hisexs white". Form 8 groups of eggs on 126 pieces per each. The exposure time is unpolarized, incoherent polychromatic radiation in group 1 is chosen equal to 0.5, 2-1, 3-2, 4-3, 5-4, 6-5, S. 7-30 Group 8 (control) process. Eggs irradiated before placing in the incubator. Incubation is carried out in the incubator ICP-90 "Caucasus" 19 days of incubation and 2 days in the Hatcher. When considering the results of incubation using conventional methods.

Example 3

Use hatching eggs chicken parent stock of cross Hisexs white". In studies using 10 groups of eggs on 126 pieces in each. For processing as a source of unpolarized incoherent polychromatic radiation is used generator helium plasma SUPR-M, generating radiation of a mixed spectral composition in the range of 200 nm and above with luminescence lines of helium. When irradiated eggs have horizontally at a distance from the nozzle of the plasma torch to the surface of eggs is equal to 30, 45 and 60 cm, the duration of treatment is 0.5, 1 and 30 seconds (table 2). Egg group 10 is not treated and used as control. The exposure dose is determined by the formula

where Ie- power radiation of the plasma torch (in particular the experience of Ie=9 mW/SR), h is the distance from the nozzle of the plasma torch to eggs, t - time processing.

Incubation is carried out in the incubator ICP-90 "Caucasus" 19 days of incubation and 2 days in the Hatcher. When taking into account the results of the incubation accepted the e method.

When analyzing the results, it was established that the method used in almost all groups leads to an increase hatchability. However, upon irradiation at different distances is more effective processing time of 0.5 C. the excess of the hatchability of irradiated eggs over control is almost the same size...4,9 4,1% at all distances. This allows you to increase the distance of 60 cm, significantly expanding, thus, the area of the workpiece and to reduce the duration of exposure. The application of irradiation had no significant effect on the weight and the length of the embryos (table 3).
