Abstract

The present invention relates to a method for spectroscopical in-ovo gender determination of fertilized and incubated bird eggs comprising the steps of: a. providing a number of passages in an egg shell of an egg for allowing entrance into an interior of the egg and/or exit from the interior of the egg of electromagnetic waves suitable for spectroscopy, b. introducing electromagnetic waves into the interior of the egg; c. detecting electromagnetic waves exiting the egg; d. analysing, by spectroscopy, of the exiting electromagnetic waves at least one passage of the number of passages; and e. determining the gender of a chicken embryo.

Abstract

The present invention relates to a method for sampling an egg, the method comprising; a) fluid coupling an interior of the egg to a source of pressure, b) controlling the pressure in the interior of the egg by the source of pressure, c) expelling an amount of fluid, in particular allantoic fluid, from the interior of the egg to the exterior of the egg as a result of the pressure in the interior of the egg, and d) collecting at least a portion of the amount of fluid at the exterior surface of the egg.

Abstract

The present invention relates to an egg carrier (1) for holding an egg in an egg handling system (2), the egg carrier (1) comprising: - an egg accommodation (3), - an egg clamping system (4) moveable between an egg securing position and an egg release position, - an operating system (5) for moving the clamping system (4) between the two positions, wherein the operating system (5) comprises an operating member (6) that is operable externally from the egg carrier (1). An assembly (16) of a number of such interlinked egg carriers (1) is further disclosed. A tray (17) comprising a tray interior accommodating such an assembly (16) is also disclosed, wherein operating members (6) are coupled or connectable for joint operation of interlinked egg carriers (1). An egg processing system is also disclosed comprising an egg conveyor tray (2), and such an egg carrier (1), wherein the egg conveyer comprises a first cam profile (19) for contacting the pair of spaced operating members in order to operate the egg clamping system (4) between the egg securing position and the egg release position. Use of an egg processing system according to the invention comprises securing an egg in the accommodation space (3) in a predetermined sampling position with respect to the egg carrier (1), tilting the egg carrier (1) around an horizontal axis into a tilted position, maintaining the egg in the predetermined tilted during a settling time, prior to taking an allantoic fluid sample from the egg.

Abstract

ABSTRACT The invention relates to an egg-examining device, comprising a sampling device (3), by means of which a liquid sample to be taken can be taken from an egg (18) of a rack (13) loaded with eggs, comprising a feeding device (1) for feeding the rack (13) loaded with eggs to the sampling device (3), and comprising a control unit (6), by means of which the feeding device (1) and the sampling device (3) can be controlled. The problem addressed by the invention is that of specifying more accurate sampling of eggs. This problem is solved in that the feeding device (1) is designed in such a way that the feeding device feeds the rack (13) to the sampling device (3) at an oblique angle of between 200 and 80 to a plane perpendicular to the direction of gravity. A lifting-out device (2) is provided, by means of which the egg (18) can be lifted out of the rack (13) and by means of which the egg (18) can be put into a sampling position, in which the liquid amount to be taken can be taken from the egg (18) by means of the sampling device (3), wherein the lifting-out device (2) can be controlled by means of the control unit (6).
