The present invention relates to a method for determining a characteristic of one or more eggs in an automated manner, comprising the steps of: a. extracting a sample from one or more eggs in an automated manner; i. holding and transferring the sample through one or more instruments to a unit for holding one or more samples; ii. ejecting an aliquot from the sample by applying sound or light energy to at least an amount of the sample; iii. entraining the ejected aliquot in a gas or liquid stream; and iv. transporting the ejected aliquot to a mass spectrometer using the gas or liquid stream; and b. analyzing the sample or an aliquot thereof in an automated manner in a mass spectrometer for the absence or presence and the amount of one or more molecules, to determine one or more characteristics of the egg.

Proposed is a technique for performing sexing of a fertilized egg with a high sexing rate at a high speed, based on image data obtained by photographing a contour of the egg. In particular, a fertilized egg sexing method, a fertilized egg sexing apparatus and a program for making a female/male judgment of a fertilized egg according to a contour of the fertilized egg by a computer are proposed. The fertilized egg sexing method includes: extracting the contour based on image data obtained by photographing the fertilized egg at different angles, calculating a short radial from the contour, calculating short radial phase differences corresponding to photographing at the angles, and making a female/male judgment using the short radial phase differences.

Disclosed is a device for contactless measuring of an embryo's heart rate in an egg whereby infrared light is sent in the egg by one light source, and the reflection of that light is detected by one or more light sensors and converted into a signal representative for the heart rate, whereby a shield is provided to avoid light that is reflected on the egg shell interfering with the light sensors. The shield is provided at the light source and not at the light sensors, whereby a light tube is provided between the light source and the egg and the light tube is internally dimensioned and positioned such that a focused light spot is directed on the egg, and the light tube is dimensioned and positioned such that light reflected on the surface of the egg on the level of the light spot cannot directly reach the light sensors.

Systems and methods for monitoring poultry house egg production. The system includes: a conveyor for conveying poultry eggs; at least one laser sensor directed in direction of said conveyor for measuring distance of said conveyor's surface and poultry eggs conveyed thereupon; a computer coupled with said at least one lase sensor; wherein, number of poultry eggs passed through said conveyor at a given moment is determined by identifying and analyzing fluctuations in measured distance from said at least one laser sensor.

A method for in-ova fertilisation determination and gender determination on a closed egg. The aim is to specify a method for the in-ovo fertilisation determination and gender determination on a closed egg. This aim is achieved by a method in which a closed egg is positioned, candled and/or illuminated, next an image of the closed egg is recorded, then the captured data are evaluated and the position of the cardiovascular system located in the egg is calculated. A detection unit is adjusted via the calculated position of the cardiovascular system by means of a positioning unit and subsequently the blood is stimulated, then the blood-specific and blood-foreign absorption spectra are detected and selected, the fertilisation is ascertained and then the spectra containing blood-foreign information are compensated by a compensation method and the spectra are classified for sex determination.
