Definitions

  • the invention relates to a greater extent to the sphere of poultry breeding and, in particular, to processes of egg selection for the incubation and egg incubation itself.
  • the poultry breeding industry faces a number of problems related to improvement of the production process efficiency, product quality and environmental friendliness of the production.
  • the incubation process is an essential and a determining production stage, in which case the market requirements need to be taken into account. For example, what the market demands most is a higher production of hens, i.e. females. Selection of males after hatching requires extermination of a substantial portion of chicks. Christian Schmidt, the FRG Minister of Agriculture, stated in his speech that up to 45 million chicks were exterminated annually just because they have a different gender.
  • the most credible methods include the DNA analysis in embryonic fluid, for example, by using nuclear magnetic resonance and spectral resonance methods, including IR Raman spectroscopy, fluorescent spectroscopy and other methods (WO 2014021715 A2 Gender, Viability and/or Developmental Staged Termination of Avian Embryos in Ovo,).
  • IR Raman spectroscopy IR Raman spectroscopy
  • fluorescent spectroscopy fluorescent spectroscopy
  • Most nondestructive methods are designed to obtain spectra of embryos by irradiating them by different types of radiation of which IR irradiation is most frequently used (US 2013/0044210 HYPERSPECTRAL IDENTIFICATION OF EGG FERTILITY AND GENDER) and to compare these spectra with earlier obtained reference spectra.
  • the same problems relate to the method of egg candling in order to obtain images of embryos and their internal structure and to determine their sexual character based on this.
  • the gender of the to-be-incubated chicks needs to be identified prior to setting the eggs in the incubator.
  • the objective of the invention is to accurately identify the egg's gender before setting and also to monitor the embryo development process during the entire incubation period.
  • Another objective of the invention is to assess productivity and developmental potency and also to obtain a healthy animal.
  • An additional objective of the invention is to control the incubation process and identify the eggs in which the embryo development is stopped or delays or specific developmental abnormalities, diseases, damages, etc. occur.
  • identification of the state of eggs includes passive recording of the dynamic electromagnetic spectrum on an egg surface, wavelet spectrum transform and spectral-dynamic analysis of correspondence of the transformed spectrum to reference markers corresponding to male or female gender of the future animal.
  • the dynamic spectrum is recorded periodically at the incubation stage, the spectrum is compared with reference markers of the corresponding development stages and then the eggs which are not suitable for further incubation are removed and discarded.
  • the essence of the claimed method resides in the use of the method of spectral-dynamic analysis of the spectra of an electromagnetic signal recorded on the egg surface using a passive electrode, i.e. without subjecting an egg to exposure of any character.
  • the method of spectral-dynamic diagnosis is known as one of the methods of medical diagnostics (the Ukraine Patent UA 34389 A, S.M. Zakirov, I.V. Orzhelsky, Bull. No. 1, 15.02.2001. The Method of Diagnosing and Correcting Wave Characteristics of the Study Objects and a Device for Implementing the Same).
  • the accuracy of this method may be improved according to the Eurasian Patent (EA 017369 THE METHOD OF IDENTIFYING AND TESTING SUB-PROCESSES IN A COMPLEX WAVE FIELD OF AN OBJECT, V.N. Rostovtsev, A.O. Lukyanov).
  • a method of forming reference markers for identifying the state of eggs which includes recording electromagnetic spectra of a control batch of eggs, processing thereof and isolating reference markers, characterized in that the dynamic electromagnetic spectra on the egg surface are passively recorded at different stages prior to and in the process of incubation, wavelet transform of spectra, spectral dynamic analysis thereof are conducted and reference markers of practically significant states for each stage are formed and the obtained markers are verified based on respective characters of the hatched chicks after completion of the incubation.
  • a sexual character embedded on chromosomes is also available among multiple markers.
  • this method is used to monitor a complete cycle of development from an egg to a chick with prominent sexual characters and isolate reference markers of the male and female gender identity and also specific stages of the embryo development, for example, formation of a nervous, a blood- vascular system and other systems.
  • individual spectra of eggs are recorded successively in the process of conveying eggs to the incubator.
  • the obtained results are used for selecting and sorting eggs based on characters of suitability for further incubation (to discard dead and defective eggs) and based on sexual characters.
  • a passive electrode successively contacts the surface of each egg or is disposed in immediate proximity to the egg surface within a specific period of time required for recording the signal.
  • An optimal time for recording a wave signal is from 3 to 30 seconds. In this case, a longer recording interval allows spectral data to be accumulated to statistically correct them and improve credibility of assessment of egg states or identify the gender.
  • the dynamic spectra of eggs are recorded simultaneously by multiple passive electrodes for multiple eggs orderly arranged, for example, in lines or matrixes. Then, the recorded spectra are converted and analyzed to compare them with reference markers. Further, eggs are sorted by discarding and removing substandard eggs.
  • Another advantage of this method is the controllability of the incubation process and timely sorting out the eggs in which abnormalities are detected.
  • the database of reference markers may also include markers of various infections, diseases and carriers of these infections and diseases. They may be timely recognized and eliminated.

Abstract

L'invention concerne des procédés de sélection d'œuf destiné à être incubé et l'incubation de l'œuf lui-même. L'objectif de l'invention est d'identifier avec précision le sexe de l'œuf avant la couvée et également de surveiller le processus de développement de l'embryon pendant toute la période d'incubation. L'identification de l'état des œufs comprend l'enregistrement passif du spectre électromagnétique dynamique sur une surface d'œuf, d'une transformée de spectre d'ondelettes et d'une analyse spectrale-dynamique de la correspondance du spectre transformé avec des marqueurs de référence correspondant au genre mâle ou femelle du futur animal. En outre, la productivité et les étapes de développement sont comparées à des marqueurs de référence. Il est tout à fait essentiel que le spectre dynamique soit enregistré avant incubation et comparé à des marqueurs de référence du genre et/ou de la productivité, puis que les œufs à incuber soient sélectionnés.
