Abstract
The invention pertains to the technical fields of bioanalytics and agriculture, and relates to a method and to an assembly for in-ovo sexing of bird eggs. The aim of the present invention is to provide a method and an assembly by means of which in-ovo sexing of bird eggs is achieved with a stable predictive accuracy of the sex and which are simple and cost-effective. The aim is achieved using a method and an assembly in which a fertilised bird egg incubated for 3 to 9 days is irradiated with at least two light-emitting laser beam sources with different excitation waves after the shell is opened, the captured and processed fluorescence scattering spectra and Raman scattering spectra being used, as complementary spectra associated with the different excitation wavelengths, to determine a classification value, and the sex being determined by comparing the determined classification value with an intrinsically determined threshold value. The method and the assembly can be used for sexing farm poultry.
