FIELD: poultry farming.
SUBSTANCE: group of inventions relates to determination of viability of avian eggs. Disclosed is an egg identification system comprising an emitter unit having a radiator housing and configured to emit electromagnetic radiation in the direction of the egg, wherein the electromagnetic radiation has a predetermined wavelength; a detector unit located at a distance from the emitter unit and configured to detect electromagnetic radiation transmitted through the egg; light control assembly located near radiator assembly between radiator assembly and detector assembly, wherein the light control assembly comprises an absorbing layer for absorbing the parasitic interfering electromagnetic radiation reflected from the egg and other components of the system, having reflecting surfaces, when emitted from the emitter unit, wherein the absorbing layer has a hole through which the electromagnetic radiation emitted by the emitter unit is able to pass to the egg; a processor configured to process the output signal of the detector assembly to determine egg viability. Also disclosed is a method for determining viability of eggs using said system.
EFFECT: group of inventions provides higher accuracy of eggs viability determination due to minimization of undesirable signals.
