Abstract: Method and device for injecting at least one product in an egg for treating the embryo. The method includes perforating a shell and an outer shell membrane on a large end of the egg, and injecting the product into an air chamber of the egg under pressure sufficient for the product to reach the amniotic fluid after passing with pressure through an inner shell membrane.

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.

Abstract: System for separating newly hatched chicks from hatching debris is provided with comprising at least one movable belt constituted of rollers arranged parallel with respect to each other, but perpendicularly with respect to their direction of displacement, and above which the chicks and the debris to be sorted are brought, with the chicks being adapted to pass between the rollers. There is further included at least one support arm which is rotationally mounted above the belt about an axis substantially parallel to the rollers of the movable belt, and that comprises means for maintaining at least one basket in which the chicks and debris to be sorted are placed.

Abstract: The invention relates to an apparatus for counting objects, which includes a light emitting system intended to form an emission zone, a light receiving system forming a plurality of substantially aligned reception points, a passage between the emission zone and the reception points to allow the conveying of objects to be counted substantially perpendicularly to the alignment of reception points, and a counting system provided to determine the number of conveyed objects as a function of the variations of light received at the reception points, which variations are due to the interpositioning of objects between the emission zone and the reception points.

Abstract: The automatic sorter ovoscope of the invention is characterized in that it comprises a light box (6) arranged under a candling head (1) which is provided with at least one suction cup (9) intended to take by suction eggs, one by one, and which is provided with vacuum means and with light sensitive means, while a device for controlling the vacuum means allows to apply by suction each suction cup to an egg to be candled and to appreciate its transparency as a function of the light intensity coming from the light box (6) and reaching the light sensitive means, the control device being servo-controlled by the signal from said light sensitive means so that the suction cup may retain by suction the egg when the signal from the light sensitive means indicates that a predetermined transparency of the egg is exceeded.
