Definitions
- the invention relates to the technical fields of bioanalytics and agriculture and relates to a method and an arrangement for in-ovo sex determination of bird eggs.
- the proposed method and the arrangement can be used, for example, to determine the sex of productive poultry, in animal husbandry and in commercial egg production.
- DE 10 2014 010 150 A1 discloses a method and a device for Raman spectroscopic in-ovo sex determination of fertilized and incubated bird eggs, in which a hole is made in the calcareous shell by a laser or mechanical perforation and the Raman scattered radiation of the irradiated blood is recorded and evaluated by means of an evaluation unit.
- a non-contact spectroscopic method and a device for optical in-ovo sex determination of fertilized and incubated bird eggs is described in DE 10 2016 004 051 A1.
- a hole is also made in the calcareous shell and the sex is determined by evaluating the Raman scattered radiation on incubation day 4, which corresponds to an early embryonic stage before the onset of pain sensation.
- DE 10 2018 105 512 A1 discloses a method for in-ovo fertilization and sex determination on a closed egg, in which a closed egg is positioned, transilluminated and/or illuminated, an image of the closed egg is then recorded, and then the the recorded data is evaluated and the position of the cardiovascular system in the egg is calculated, a detection unit is set over the calculated position of the cardiovascular system by means of a positioning unit and the blood is then stimulated, after which the blood-specific and non-blood absorption spectra are detected and selected, fertilization is determined and then the spectra are compensated with non-blood information by a compensation method and the spectra are classified for gender determination.
- a disadvantage of the known solutions is that the in-ovo sex determination is carried out with an insufficiently stable prognosis accuracy. It is also disadvantageous that known methods and arrangements are complex and expensive.
- the object of the present invention consists in specifying a new method and an arrangement provided for carrying out the method, with which the in-ovo sex determination of avian eggs is carried out with a high and stable prediction accuracy of the sex and which are simple and inexpensive to carry out.
- a method for in-ovo sex determination of bird eggs in which the following method steps are carried out:
- the temperature of the fertilized and incubated bird's egg is adjusted to between 35°C and 38°C while the method is being carried out.
- the at least two different excitation wavelengths differ by at least 0.3 eV of the emitted light.
- At least one first laser beam with an excitation wavelength of 400 nm to 570 nm and at least one second laser beam with an excitation wavelength of 640 nm to 790 nm are used.
- complementary spectra in a backscatter wavelength range of 620 nm to 700 nm and 820 nm to 900 nm are used to determine the classification value.
- Complementary spectra in the form of sex-specific spectra of molecular concentrations in the blood are advantageously processed to determine the sex.
- the classification value is also advantageously determined by algebraically linking the respective intensity maxima Ismax of the complementary spectra and/or spectral range of fluorescence and Raman scattering assigned to the different excitation wavelengths, with the classification value being particularly advantageously determined by quotient, difference and/or sum formation .
- the intrinsically determined threshold value is determined by comparison operations of the classification value, taking into account a given training sets, formation of intensity ratios and/or neural networks is realized.
- an arrangement for in-ovo sex determination of fertilized and incubated bird eggs using the method described above comprising
- At least one egg storage unit on which at least one fertilized bird egg that has been incubated for 3 to 9 days is arranged in a secured position
- At least two light-emitting laser beam sources the laser beams of which have different excitation wavelengths and stimulate fluorescence and Raman scattering in the blood of at least one component of the developed extraembryonic cardiovascular system, wherein
- At least one detector device for detecting the excited fluorescence and Raman scattering
- Classification unit for determining a classification value and determining gender.
- the laser beam sources have excitation wavelengths Ai, A2 . . . Ai in the range from 400 nm to 1064 nm. It is also advantageous if the different excitation wavelengths differ by at least 0.3 eV.
- a first laser beam source has an excitation wavelength Ai of 500 nm to 550 nm and a second laser beam source has an excitation wavelength A2 of 750 nm to 790 nm.
- the laser focus of the at least two laser beams in the xyz direction and/or the beam waist is set essentially the same.
- the present invention provides a new method and an arrangement for carrying out the method, with which the in ovo sex determination of avian eggs is carried out with a high and stable predictive accuracy of the sex on the basis of the biochemical molecular profile of the avian egg and which has a simple and enable a cost-effective procedure for sex determination. Furthermore, the present invention describes a solution with which the surprisingly found natural variations in the biochemical molecular profile of bird eggs can be compensated for in the measurement.
- the main advantages of the solution according to the invention are achieved by a method for in-ovo sex determination of bird eggs, in which in a first step at least one fertilized bird egg incubated between 3 and 9 days is provided, in which the lime shell has an opening in the area of the pointed or blunt pole is generated.
- the blood of at least one component of the developed extra-embryonic cardiovascular system of the embryo is emit- ted through the opening in the calcareous shell with at least two light sources Laser beam sources irradiated.
- the blood is irradiated by means of at least two laser beams with different frequencies and thus different excitation wavelengths.
- the excitation of the blood is carried out with at least two different excitation wavelengths in the range from >400 nm to 1064 nm is realized.
- At least two laser beam sources with laser beams of different excitation wavelengths are used. This ensures that the blood of the embryo is excited in the same volume fraction, which causes fluorescence and Raman scattering as a function of the excitation wavelengths, and as a result at least two different, complementary spectra are obtained.
- complementary spectra should be understood to mean such intensity spectra of fluorescence and Raman scattering that lead to a reversal of the imaged spectra of male and female spectral regions due to different excitation wavelengths.
- the complementary spectra are information about sex-specific molecule concentrations, which are obtained from the components of the blood, namely hemoglobin and protoporphyrin become.
- the spectra of two different biochemical molecules or molecular structural units are selected whose relative concentrations with regard to sex are inversely complementary. Referring to Figure 6, one biochemical compound is present at a higher concentration in female embryos relative to male embryos and, complementarily, another biochemical compound is present at a lower concentration in female embryos relative to male embryos.
- the inversely complementary present concentrations of the biochemical molecules with regard to gender advantageously lead to an amplification of the gender-specific signals and can at the same time be used for intrinsic referencing.
- laser beam sources are used to irradiate the blood of the embryo, in which the excitation wavelengths of the at least two laser beams differ from one another by at least 0.3 eV.
- the fluorescence scattering of the blood of female embryos showed a higher intensity compared to the fluorescence scattering of the blood of male embryos.
- the intensity of the fluorescence scattering is lower than the intensity of the fluorescence scattering of the blood of male embryos and the complementary spectra and their intensity maxima are thus reversed in a gender-specific manner behave.
- the profile of the fluorescence intensities as well as the Raman spectra show gender-specific molecular signals that can be used for evaluation and gender recognition.
- the detection of the fluorescence and Raman scattering excited in the blood takes place using at least one detector device, with the subsequent processing of the complementary spectra taking place using an evaluation unit taking into account at least one intrinsic referencing and one or more computationally determined intrinsic referencing variables or referencing functions.
- intrinsic referencing is to be understood as a procedure for processing and evaluating the fluorescence and Raman scattering obtained, in which process parameters that deviate and possibly influence the results or varying gender-unspecific signals are compensated for or normalized, and the result of the intensity spectra is thus normalized by absolute fluctuations the intensities or other internal or external influences is adjusted.
- a freely definable internal standard value or an isobestic point to be designated in analogy to absorption spectroscopy can be determined. In this way, in particular, a better comparability of the registered intensity spectra and a higher prediction accuracy in gender determination is achieved.
- the recorded and processed intensity spectra of the fluorescence and Raman scattering are output from the complementary spectra assigned to the different excitation wavelengths.
- the sex of the embryo is subsequently determined from the complementary spectra obtained by determining a classification value using algebraic, univariate, multivariate and/or logical linking.
- the classification value can be determined by algebraic arithmetic operations of the respective intensity maxima of the different excitation wavelengths associated complementary spectra of fluorescence and Raman scattering is determined. This procedure offers the advantage of a quick, simple and cost-effective determination of the classification value in the gender-specific determination using one or more cost-effective detector devices, such as one or more diodes.
- a data evaluation and classification of the intensity spectra of the fluorescence and Raman scattering can be done, for example, by classifying the fluorescence and Raman spectra of the excitation wavelength Xi and fluorescence and Raman spectra of the excitation wavelength X2 using classifiers in a first step, with the classification values being determined for both classes .
- classifiers in a first step, with the classification values being determined for both classes .
- two classification values for the classes "male” and "female” are determined from the determined classification values.
- a further algorithm converts these classification values into a definition and output of the gender, with the gender assignment being able to be output either singularly or in binary with an indication of the probability.
- the binary output has the advantage that less clear sex statements can be evaluated from a hatchery economic point of view.
- the classification value is determined taking into account predetermined spectral ranges which are assigned to the complementary spectra of the respective different excitation wavelengths.
- the classification value determined can be classified via comparison operations of the classification value using a predetermined training set, formation of intensity ratios and/or neural networks be realized, which result in a threshold value for gender determination.
- the temperature of the blood in the extra-embryonic cardiovascular system of the embryo has a significant influence on the metabolic function and on the intensity of the excited fluorescence and Raman scattering after irradiation with laser beams.
- the temperature of the fertilized and incubated bird egg is set to between 35°C and 38°C during the implementation of the method.
- a significantly improved and compact arrangement is proposed according to the invention, which has at least one egg storage unit on which at least one fertilized bird egg incubated for 3 to 9 days is arranged in a secured position.
- it is proposed to use at least two light-emitting laser beam sources whose laser beams are superposed in different ways to one another
- the blood can be irradiated by the at least two lasers with different excitation wavelengths.
- the irradiation can take place at different positions in the cardiovascular system, provided that it is ensured that volume components of the blood are irradiated.
- a complex positioning device and detection of the extra-embryonic cardiovascular system can be omitted, which leads to a cost-effective arrangement.
- the arrangement according to the invention also has at least one device for positioning the laser focus, with advantageously the position of the focus of the at least two laser beams in the xyz direction and/or the beam waist in the essentially set the same.
- the arrangement according to the invention has at least two beam splitter devices with which the excited fluorescence and Raman scattering can be separated depending on the excitation wavelength.
- the proposed beam splitter devices consist of excitation wavelength-dependent reflection and transmission devices and enable a quick and easy separation and thus targeted forwarding of the excited fluorescence and Raman scattering for a time-saving and quick sex determination with the information obtained.

- an egg storage unit not shown.
- An illumination device 20 with an illumination fiber 21 for illuminating the interior of the egg and an additional camera 19 are arranged in the immediate vicinity of the opening of the bird's egg.
- the excited fluorescence and Raman scattering, which is dependent on the different excitation wavelengths, and the illumination beams of the illumination device 20 are separated via the beam splitter devices 9 (single edge 514 nm), 10 and 11 (T 813.5 - 1100 nm), and are detected by the detector devices 14 and 17 depending on the wavelength forwarded to an evaluation unit (not shown).
- FIG. 2 shows the mean values of the evaluated intensity spectra on incubation day 3.5, 5.5 and 6.5 for female and male embryos.
- the spectra clearly show the differences in intensity of the complementary spectra at the excitation wavelengths Ai and A2 both with regard to sex and regarding the incubation day. A decrease in the relative intensity differences between female and male embryos with increasing incubation duration can also be seen.
- the spectra in Figure 2 also illustrate the complementary character of the spectra, ie the different, inversely behaving intensities at the excitation wavelengths Ai and A2.
- the intensity spectra Isi and Is2 of the fluorescence and Raman scattering which are dependent on the excitation wavelengths Ai and A2, are obtained for evaluation and sex determination.
- the spectra Isi and Is2 are subjected to an algebraic, univariate, multivariate and/or logical combination in the logic unit 201 .
- the calculated intensity spectrum with intrinsic referencing (IIR) is subsequently subjected to the classification algorithm 202, the classification algorithm outputting probabilities for belonging to the “female” and “male” classes.
- the probabilities of class membership are passed as classification values for the class "female” (S$) and for the class "male” (Sj) to an evaluation unit with an algorithm for determining and outputting sex 203 .
- exemplary embodiment 3 presents a further possibility for evaluating and classifying the spectra.
- An arrangement for in-ovo gender determination is provided and the method steps according to exemplary embodiment 1 are carried out.
- the fluorescence and Raman spectra Isi of the excitation wavelength Xi and the fluorescence and Raman spectra Is2 of the excitation wavelength A2 are classified independently of one another using the classifiers 202a and 202b, with the classification values S?i S ⁇ ji and S?2 S ⁇ j2 can be determined for both classes.
- two classification values S 1 and 8 2 for the classes “male” and “female” are determined from the 4 classification values S 1 S ⁇ ji S 2 S ⁇ j2. These classification values are compared by a further algorithm 204 and converted into a gender definition and output.
- the comparison algorithm advantageously outputs probabilities for belonging to the “female” and “male” classes.
- the probabilities of class membership are passed as classification values for the class "female” (S$) and for the class "male” (Sj) to an evaluation unit with an algorithm for determining and outputting sex 203 .
- This also advantageously allows the sensitivity and/or specificity of the gender determination to be adjusted for each class. This allows, for example, a very precise determination of female or male eggs, which can be adjusted according to business criteria. However, it is also possible to carry out the gender assignment singularly
- Figure 6 shows schematically the energetic states in sex specific molecules or molecular groups.
- the energetic excitation takes place with the excitation wavelength Xi 301 and the excitation wavelength X2 401.
- the energy bands of the excited energy level 302 and 402 are separated by at least 0.3 eV. This ensures that the energetic overlap of the fluorescence transitions 303 and 403 is only insignificant.
