The hyperspectral measurement technology

Let there be light

Due to gender-specific plumage colours in brown layer lines, the sex can already be determined in the embryo based on its first feathers. This is how it works: inside the measuring chamber, eggs are illuminated from below and a spectral image is taken from above. The spectrum of the image is then analyzed by a computer automatically. By using an algorithm, that, in contrast to neural network, is based on a so-called parametric model, the sex can be determined.

The procedure is non-invasive, keeping the eggshell intact. Based on differences in the measured light spectra, an algorithm classifies the gender. In addition to sex determination, unfertilized eggs are also identified and sorted out at the same time.

The hyperspectral measurement technology does not require expensive consumables. This is another reason why it is around one-third of the cost of alternative methods and, most importantly, is more environmentally friendly.
