Electronic identification in rabbits: two body sites of injectable transponder

AbstractIdentification and monitoring of farm animals are effective tools for traceability. Actual livestock identification systems (ear-tags, tattoos, etc.) are not completely efficient and offer some inconveniences. The use of injectable transponders might be a reliable method for individual identification, allowing the improvement of the data recording and the farm management. The aim of this experiment was to evaluate the applicability of injectable transponder in live rabbits. A total of 40 fattening rabbits of 55 days old were injected with 23 mm passive FDX-B transponders (Datamars, Switzerland), preloaded into a needle in a sterilised packaged and applied by using a transponder injector (Planet ID, Germany). Two body locations for transponder’s injection were studied: laterally to the neck (n=20) and armpit (n=20). Readings of the transponders were performed using portable ISO transceiver, before injection, after injection, the day after, after one week, after one month, before the slaughtering pr...
