Abstract:
1. A method for determining the sex of fertilized and non-incubated bird's eggs, wherein a bird's egg comprises a solid egg shell, an egg yolk surrounded by the solid egg shell and other egg envelopes and a germinal disc coordinated to the egg yolk with the following steps: furnishing a hole in the egg shell; positioning the hole in a region of the germinal disc; guiding a probe including an optical crystal through the hole toward the germinal disc having germinal disc cells; measuring spectra through the hole in the egg shell with the probe including the optical crystal; determinating the germinal disc cells spectroscopically in-ovo; receiving rapidly and back-reaction free infrared spectra or near infrared spectra at the optical crystal; using an attenuated total reflection within the optical crystal by an evanescent field in a region of the germinal disc; inducing attenuation or extinction due to a spectral absorption of gender specific germinal disc cells; accompanying the positioning of the optical crystal by a permanent automatic evaluation of the recirculated spectra for a determination of gender specific germinal disc cells; evaluating the spectra with an evaluation unit; identifying the sex of the fertilized egg through automatic classification of reflection spectra; displaying unequivocally the sex of the fertilized egg with a display unit.
