GENDER VIABILITY AND/OR DEVELOPMENTAL STAGE DETERMINATION OF AVIAN EMBRYOS IN OVO

摘要

The present invention relates to a process for the non destructive determination of gender developmental stage and/or viability of an avian embryo in an egg comprising (a) detecting at least a first developmental marker compound selected from sugars and/or amino acids precursors and metabolites thereof in an egg at a time period of from the beginning of the incubation of the egg until the hatching;(b) measuring the amount of the at least first detected developmental marker compound and(c) comparing the amount to a base line established for male and female developmental stage of the embryo and/or alive and deceased or non developed embryo to determine whether the embryo is viable male and/or female and/or the developmental stage of the embryo.
