Method of introducing material into eggs during early embryonic development

摘要

A method of introducing a substance (14) into a bird egg through the shell thereof comprises the steps of applying a seal (10) to the exterior of the shell, inserting an injection device (11) through the seal (10) and into the egg, injecting the substance (14) through the injection device (11) and into the interior of the egg, and withdrawing the injection device (11) from the egg through the seal (10). The method is particularly preferred for injecting substances into the albumin during the first quarter of incubation through the bottom of the egg when the small end (8) of the egg is oriented downward to prevent the introduction of air bubbles through the opening formed in the shell by the injection device (11).
