Method and device for automatically detecting mating of animals

A device for automated detection of attempts to mate a first, female animal by a second, detecting animal, said device comprising:

• an electronic tag configured to be placed in or fixed at an organ of the female animal, the electronic tag being a passive tag without any source of energy and generating a signal only upon detector-activation, the electronic tag not generating signals until being detector-activated by the detecting animal making a mounting attempt on the female animal by the detecting animal being on top of the female animal;
• a detector configured for emitting an electromagnetic field activating said electronic tag when said electronic tag is located in or fixed at the organ of the female animal and said detector is attached on the detecting animal,
• the electronic tag being detector-activated by the detecting animal being on top of the female animal so that the detector establishes a communication with the electronic tag worn by the female animal, wherein upon being activated, said electronic tag emits an identification of said female animal in an identifying signal modulating the electromagnetic field and picked up by the detector, said detector comprising an identifier configured for identifying said passive electronic tag based on the identification within the identifying signal emitted by the electronic tag;
• and
• a fastener configured for attaching said detector on the detecting animal in a position to ascertain that the mounting attempt occurred.
