INTRODUCTION OF MATERIAL IN EGGS DURING EARLY EMBRYOUS DEVELOPMENT.

摘要

A method of introducing a substance (14) into a bird's egg through its wrapper comprises the steps of applying a gasket (10) to the outside of the wrapping, inserting an injection device (11) through the gasket ( 10) and into the egg, inject the substance (4) through the injection device (11) and into the interior of the egg, and remove the injection device (11) from the egg through the joint (10). The procedure is particularly advantageous for injecting substances into the albumin during the first quarter of the incubation through the bottom of the egg when the small end (8) of the hole is oriented downwards to prevent the introduction of air bubbles through opening formed in the envelope by the injection device.
