  • Method and device for the raman spectroscopic, in ovo sex determination of fertilised and incubated birds' eggs
    Patent number: 9835560
    Abstract: The invention relates to a method for the Raman spectroscopic, in ovo sex determination of fertilized and hatched birds' eggs (1), wherein the embryo, including the extra-embryonic structures, can move in the egg, and is not yet attached to the shell at the time of measuring.
    Type: Grant
    Filed: July 3, 2015
    Date of Patent: December 5, 2017
    Assignees: TECHNISCHE UNIVERSITAET DRESDEN, UNIVERSITAET LEIPZIG
    Inventors: Roberta Galli, Grit Preusse, Edmund Koch, Gerald Steiner, Maria-Elisabeth Krautwald-Junghanns, Thomas Bartels

  • Method and device for determining the sex of fertilized, non-incubated bird eggs
    Patent number: 8624190
    Abstract: The invention relates to a method and a device (1, 100) for determining the sex of fertilized, nonincubated bird eggs (13, 130), where an egg (13, 130) has a solid egg shell (14), an egg yolk (2) which is surrounded by the egg shell and further egg integuments and a blastodisc (3) associated with the egg yolk (2), and where a probe (4, 40) for measuring a spectrum is introduced through a hole (17) of the egg shell (14) towards the blastodisc (3) with blastodisc cells (23), with the following steps: —positioning of the probe (4, 40) in the region of the blastodisc (3), —spectroscopic in-ovo characterization of the blastodisc cells (23), and —identification of the sex by an automatic classification of spectra.
