Abstract: A system for the surveillance of animals includes identification and measuring elements attached to the animals, as well as at least one local level information system (115), wirelessly connected to the identification and measuring elements of a certain group of animals for saving animal-specific measuring results into the information network. Aiming to provide a new kind of a surveillance system for domestic husbandry that enables different interest groups to monitor the kind of a group of animals they wish, the system includes at least one higher level information system, connected to the chosen local level system through a communications network for the reception of animal-specific measuring results from at the minimum one local system, and at least one software application using the data gathered in the higher level system to produce information about the animals to at the minimum one higher level information system by processing the collected data.
