DEVICE AND METHOD FOR IN-OVO DETERMINATION OF THE SEX OF A FERTILISED BIRD EGG

摘要

The invention relates to a device (12) for the in-ovo determination of the sex of a fertilised bird egg (10), having – a light source (14) for emitting excitation radiation for exciting fluorescence in a region (16) inside the bird egg (10), - a spectroscopic apparatus (18) for analysing, in a temporally and/or spectrally-resolved manner, fluorescent radiation emitted from the region (16) inside the bird egg (10), - an evaluation unit (20) for determining the sex from the data determined by means of the spectroscopic apparatus (18) and – a measuring head (22) for jointly transmitting the excitation radiation into the bird egg (10) and receiving the fluorescence radiation from the bird egg (10). According to the invention, the measuring head (22) has an optical fibre system (28) with a head end (30) for transmitting the excitation radiation and receiving the fluorescence radiation. The invention also relates to a corresponding measuring head (22) and a corresponding method for the in-ovo determination of the sex of a fertilised bird egg (10).
