A total of 1032 pigs, fattened and slaughtered in commercial conditions, were identified with five different identification devices: plastic button ear tags (CC), half-duplex (CH) and full-duplex B (CF) electronic button ear tag; and, half-duplex (IH, 32 mm) and full-duplex (IF, 34 mm) intraperitoneally injected transponders; button ear tags had different security systems (A: open, y C: closed). Afterwards the identification, the tracking of identification devices was made without no negative effects on animal health. Readability was checked by using full-ISO handheld transceivers. On farm and transport results showed differences in losses between CH-C (5.7%) and IH (1.3%); 0,7% electronic failures were observed in CF. Observer slaughterhouse losses were 1.7%, 4.4% and 5.7% for CC, CH and CF respectively; and, a 1.5% of electronic failures was checked. The better traceability was obtained with IH (98.7%) and IF (97.9%); and it not differed from CC-C (97.3%). The lowest traceability was obtained with half-duplex (90.6%) and full-duplex (88.6%) electronic ear tags. Pig identification by using intraperitoneally injected transponders appears to be a reliable identification system for improving pig traceability in practice. Likewise, the combined use of conventional and electronic procedures of identification may be a good strategy tus contributing in a simultaneous manner for improving herd management and treacibility of pork chain.
