Method for in-ovo fertilisation determination and gender determination on a closed egg

A method for determining fertilization and sex in ovo on a closed egg, only containing natural pores, comprising the method steps of:

• a) positioning the closed egg, b) candling and/or illuminating the egg by means of at least one light source using light in the spectrum of visible and/or near-infrared light, c) recording an image of the candled and/or illuminated closed egg by means of an optical recording system and evaluating captured data of a generated image by means of an evaluator, d) calculating a position of a cardiovascular system situated in the egg from the evaluated data of a camera image by means of the evaluator, e) setting a detector above the calculated position of the cardiovascular system by means of a positioner, f) exciting blood situated in the cardiovascular system by means of an exciter, g) detecting and selecting blood-specific absorption spectra and blood-extrinsic absorption spectra by means of a capturer, h) determining fertilization, wherein the following method steps are performed after fertilization has been established, i) compensating the spectra with blood-extrinsic information by a compensation method by means of the evaluator, j) classifying the blood-specific absorption spectra by means of a multiple classification method for determining sex.
