Abstract: The present invention relates to an automatic egg examining device for differentiating between fertilized eggs and unfertilized eggs, comprising emission means (3), which comprise, for each egg to be examined, at least one coherent laser source forming a coherent optical beam (31) directed at an egg (9) to be examined, reception means (4), which receive the light flux passing through the egg, and data processing means (7), which process the light flux received by said reception means in order to determine the state—fertilized or unfertilized—of the egg.

Abstract: The invention relates to a device for injecting at least one fluid substance into an egg, of the type that comprises an injector body equipped with a protruding piercing needle for injecting said substance into the amniotic liquid of said egg and/or into the embryo contained therein, the body being connected with external means for supplying said substance, characterized in that drivable means are integrated in the body for expelling towards said needle one or more adjustable variable and parametered amounts of substance from said supply means. The invention also relates to equipment including a plurality of such devices.
