<p>A high speed automated injection system for avian embryos is disclosed which can inject eggs with fluid substances. The device includes suction devices (37) which lift eggs out of engagement with surfaces, rather than pushing them, before injecting them. By providing punches (43) for first forming an opening in the egg shell and separate needles (42) which then inject the avian embryo or the surrounding environment with a fluid substance, the device avoids the undesirable mechanical compromise of using a single needle or punch to both puncture the shell of an egg and deliver fluid substances to the interior of the egg.</p> |
