Einsatz eines UHF-Transponders zur Simultanerfassung von Mastschweinen

Currently used low frequency RFID systems for electronic animal identification can only identify animals separately rather than several animals simultaneously. Ultra high frequency systems (UHF) provide simultaneous identification. However, UHF systems are susceptible to disturbances prevailing in animal housing systems. In this field trial the suitability of a UHF system for identification of fattening pigs was examined. 22 fattening pigs were tagged with UHF transponders in the growing period. The trials showed an identification rate of 73.9 % in the finishing period. No losses or malfunctions of transponders were observed during the trial.
