ABSTRACT:
The present invention provides a non-invasive method and apparatus (44) for sexing members of the avian species in the egg (26). Further, the present invention when in combination with an egg sorter (28) provides an automated method for sexing and sorting members of the avian species in the egg which is rapid and reliable. In particular, the method uses nuclear magnetic resonance to determine whether the live embryo within an egg contains male or female sex organs. The invention further provides an apparatus for sexing members of the avian species in the egg which comprises a conveyor (24) that transports a plurality of eggs through the apparatus (44) wherein the sex of the embryo is determined. Then the egg is transferred to the egg sorter which sorts the eggs into a first group comprising eggs containing male embryos and a second group comprising eggs containing female embryos. The present invention can further sort eggs into a third group comprising eggs which are unusable.
