METHOD OF CLOSING DEFECT OF FERTILIZED EGG WHEN CREATING EXPERIMENTAL MODEL Russian patent published in 2020 - IPC A01K45/00 G01N33/08 

FIELD: poultry farming.

SUBSTANCE: invention relates to poultry farming, in particular to a method for treatment of a fertilized egg. Method of closing a hole of a fertilized egg when creating an experimental model involves placing an egg horizontally with an embryo upwards. Performing the hole in the side on the germ side. Subsequent analysis and/or treatment of nucleating agent and closing of a hole in a shell. According to the invention, a shell hole fragment is used to close an opening of the shell. Donor egg is treated with a disinfectant. From the shell of the donor egg, a fragment larger than the size of the hole in the experimental egg is cut out. Egg-donor shell fragment is cut out together with the sub-shell. After the experiment on a chicken embryo, a hole of the egg shell is closed with a donor fragment and sealed, for example, by softened wax.

EFFECT: invention provides achieving the technical result consisting in improving the quality of studies by eliminating the risk of developing anaerobic bacterial infection, preserving the possibility of rotating the egg, eliminating the loss of choroid-allotopic fluid and enabling the parameters of natural incubation conditions to be achieved.
