After 5 min installation for laser light treatment and disinfection of eggs ready for use.

Trays hatching eggs (13) or boxes of Chicks (20) are placed on the stand (12). Click KMZ-2 turns on the motor transporting device (10), the trays are served by the chain conveyor (14) and moving the camera illumination (17) with smooth transition, the first heated gas discharge lamp DMESG-500 (6) and disinfected from all sides bactericidal lamps PDR-30 (21), then exposed to radiation of helium-neon laser LGN-104 (2), UV lamp CES-400 (7), bacterin is the breaking of lamps PDR-15 (9), then issued on the stand for trays (12) on the opposite side of the control panel.

Exposure time exposure of hatching eggs and day-old Chicks is controlled by switch KMZ-2.

To determine the biological result of the invention selected on the principle of analogues of hatching eggs 6 groups 144 of the embryo, from which 1 group passed through the pipeline when you turn off the lights and served as a control, 2 group were treated with radiation of a helium-neon laser LGN-104 wavelength 632, 8 nm, the optical density of the flux of 50 mW/cm2in exposure 3 min, 3-gas discharge lamp DMESG-500 wavelength 630-650 nm, the average dose on the surface of eggs 23.1 erg in exposure 5 min, 4-mercury-quartz lamp CES-400 wavelength 400/185 nm, the average dose on the surface of eggs 20 mayor/g in exposure 3 min, 5-three bactericidal lamps PDR-30 on all sides in exposures over 3 min, 6 group treatment of chicken embryos by the emission of a helium-neon laser LGN-104 a wavelength of 632.8 nm, the density of optical flow on the surface of eggs 50 mW/cm2, gas discharge lamp DMESG-500 wavelength 630-650 nm, the average dose on the surface of eggs 23.1 erg, mercury-quartz lamp CES-400 wavelength 400/185 nm, the average dose on the surface of eggs 20 mayor/h exposures for 3 min combined with the simultaneous processing of eggs from all three sides of the bacteria is rizenymi lamps PDR-30 wavelength 254/800 nm, the maximum absorption at 254 nm, the average dose on the surface of eggs 30 watts exposures for 3 min before incubation at 6, 12 and 18 days of embryonic development.
