Abstract: A distribution system for distributing dosed amounts of a treatment substance to a plurality of injectors of an egg injection device, and to an injection device equipped with such a distribution system. The distribution system comprises at least one syringe pump comprising an actuator for actuating the piston of a syringe, a discharge tube connected to the outlet orifice of the syringe, feed tubes connected in parallel to the discharge tube via a valve system, each feed tube being intended to be connected to an injector, and a controller capable of controlling the actuator and the valve system for distributing dosed amount of substance contained in the chamber through the feed tubes, to injectors.

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: An injector for injecting at least one substance into eggs, comprising an injection body that can be moved between a raised position and an injection position, and equipped with an injection conduit, an injection needle, a guiding and protection tube of the needle subject to elastic stress by elastic means to an idle position and capable of being moved towards a retracted position by pressing its distal end against an egg when the injector is in the injection position. The injector is equipped with control means for controlling the supply of said injection conduit with at least one substance, said tube cooperating with said control means to disable the supply of said injection conduit when said tube is in the idle position and to enable the supply of said conduit when said tube is in the retracted position.

Abstract: An injection method for injecting a substance into eggs, and an injection head for implementing said method. The method generally includes piercing the shell and at least the shell membrane of an egg by moving a needle, and then injecting the treatment substance via said needle, said piercing step comprising a first movement of the needle to pierce the shell with a first penetration force and then a second movement of the needle to pierce at least the shell membrane with a second penetration force lower than the first penetration force.

Abstract: A living animals conveying device for sorting animals with respect to a characteristic such as color, size, gender, or weight. In the case of chicks, an embodiment of the invention includes a section for conveying chicks with chicks positioned in buckets with their wings spread out, and an automatic chicks sexing system. A first endless bucket conveyor comprising pre-positioning buckets able to individually receive and transport a living animal, is oriented with respect to a second endless bucket conveyor, comprising sorting buckets able to individually receive and transport a living animal, the first conveyor and the second conveyor being arranged in such a way that each pre-positioned living animal in a pre-positioning bucket falls from the pre-positioning bucket into a sorting bucket arranged below the pre-positioning bucket.
