FIELD: agriculture.
SUBSTANCE: present invention relates to a method of administration of medicinal agent in egg and to the injection head to implement this method. The said method comprises the step of puncturing the shell and at least put amen by the moving needle, and then the step of inserting through the said needle of medicinal agent; at that the said step of puncturing includes the first movement of needle (22) to puncture the shell (91) under the influence of force of the first puncture, and then the second movement of the needle to puncture at least put amen (92) under the influence of force of the second puncture, less than the force of the first puncture. The injection head for administration of at least one medicinal agent in the egg comprises: a syringe holder designed to be placed over the eggs to be processed, at least one syringe mounted on a syringe holder and containing the syringe housing, the injection needle mounted on the housing with ability of filling with at least one substance for injection, and an individual means of movement made with the ability to move the housing of the syringe between the raised position and the position in which the injection is performed, also contains a fixed mounting plate (5), to which the said syringe holder (4) is movably mounted, and the main unit of movement (6), made with the ability to move the syringe holder between the upper position and the lower position, and the injection head can be controlled by the main unit of movement, to move this syringe holder from its upper position to the lower position to puncture the shell (92) of the egg (9a, 9b, 9c) with the needle (24) of the syringe housing (21) in the raised position with activation of the force of the first puncture, and then movement of the syringe housing from its raised position to the injection position, for puncturing with this needle of put amen of the egg with the force of the second puncture which is less than the force of the first puncture, for administration of the medicinal agent into the egg.
EFFECT: use of this invention enables to prevent the inevitable injuries of embryo.
