GENDER, VIABILITY AND / OR DEVELOPMENTAL STAGE DETERMINATION OF AVIAN EMBRYOS IN EGG Russian patent published in 2019 - IPC G01N33/50 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, namely a method for controlling the incubation of an avian embryo in an egg to obtain a sample of eggs by determining the gender, developmental stage and / or viability of an avian embryo. In order to determine the gender of an avian embryo, the level of glucose, choline and / or valine is measured in the period from the start of incubation of the egg to hatching, followed by comparing this number with the base value set for the male and female embryo. To determine the developmental stage or viability of the avian embryo in the egg, the level of trimethylglycine, aspartate, arginine, glutamate, glutamine or proline is measured in the period from the start of incubation of the egg to hatching, and then this amount is compared to the base value set for the developmental stage of the embryo, either alive or dead, or an undeveloped embryo to determine if the embryo is viable or the stage of development of the embryo.

EFFECT: invention provides for the determination of the viability of avian embryos, the control of their development, and the separation of male and female eggs for further use.
