“…Thomas et al (2006) reported that the overall loss of e-ETs was 9.9 % for sheep in 4.5 months and 19.2 % for lambs in about 3 months, and these lost rates were unacceptably high for official use. Elec- tronic and visual ear tag losses observed in the study were lower than those reported in the literature (Caja et al, 1999;Conill et al, 2002;Rusk, 2002;Ghirardi et al, 2006;Thomas et al, 2006). …”

Abstract. The objective of this study was to evaluate the effectiveness of electronic and visual ear tags in animal traceability, and to investigate the effect of placement site on ear-tag retention in Akkaraman lambs under rural conditions. A total of 380 lambs were identified with electronic and visual ear tags. Electronic and visual ear tags displayed 98.9 and 98.7 % readability at the end of 7 months, and 98.0 and 98.0 % readability at the end of the first year after tagging, respectively. Regarding the placement site, it was observed that there was more loss in ear tags placed on the mid-point part of the ear than the first-quarter part from the head side, but the difference was not statistically significant (P > 0.05). Breakages and electronic failures were not recorded during this study. In conclusion, electronic and visual ear tags demonstrated similar on-farm efficiency for the identification of Akkaraman lambs and fulfilled the minimum efficiency of 98 % required by the International Committee for Animal Recording (ICAR) for an official animal identification device at the end of the first year after tagging. Based on the findings of the study, placement of the ear tag in a cranial position and near the base of the ear would be advised.

“…The retention of e-ETs and v-ETs in lambs has shown remarkable variability, ranging from 85.4 to 100 % in e-ETs (Thomas et al, 2006) and 91.7 to 100 % in v-ETs (Caja et al, 1999Conill et al, 2002;Ghirardi et al, 2007). In addition, the tagging site on the animal's ear is critical for its retention (Caja et al, 2004).…”

“…The back scapular position was chosen as being the applied method in dogs, cats and horses, and with previous research on transponder injection in rabbits (Climent et al, 2000). The armpit site has been previously studied in sheep, goats and cattle (Caja et al 1998, Conill et al, 2000Conill et al, 2002). Fattening rabbits were weighed before injection, one week and one month after injection, and before slaughter.…”

Identification and monitoring of farm animals are effective tools for traceability. Current livestock identification systems are not 100% efficient and present certain disadvantages such as losses, breakages and an unreadable identification code. The use of injectable transponders may be a reliable method for individual identification, providing an improvement in data recording and farm management. The aim of this experiment was to evaluate the practical aspects concerning injection technique, readability and retrieval of injectable transponders in live rabbits. A total of 60 rabbits (40 fatteners and 20 does) were injected with 23x3mm passive FDX-B transponders (Datamars, Switzerland), inserted into a needle, wrapped in a sterilised package and applied by a specific injector (Planet ID, Germany). Two different body sites were evaluated: back scapular (n=30) and armpit (n=30) position. The readings of the transponders were performed by using an i-max plus portable reader (Datamars, Switzerland) at different times: before and after injection, one day, one week and one month after injection. Does were read monthly during 1 year, while fatteners before the slaughtering process. To evaluate the effect on productive performance, fattening rabbits were compared to a control group. The readability of transponders injected in fatteners until slaughter and in does until 1 year after injection was 100%. No harmful effects were observed and no significant difference in weight was found in the two injection groups, compared with the control group. The retrieval was performed by a single operator at skinning, with 100% of transponders recovered. The site of the injection did not affect the migration rate, although it was high in both cases. The feasibility of subcutaneous transponder injection in live rabbits is recommended in the two body positions analysed. However, specific training and operator experience are necessary to improve the efficiency of this identification system.

“…The system structure of complete traceability from farm to consumer is shown in Fig. 1. Tracking cattle from the farm to the processing plant with RFID RFiD is beginning to be widely used for tracking cattle from birth to the processing plant (Conill et al 2002). The program is designed to track the animal from birth to the plant.…”

Radio frequency identification (RFID) technology is an automatic identification and data capture (AIDC) technique and it is the representative technology for handling beef traceability. In this paper we offer a complete solution including: frequency, identifier information system, information system, data organisation, tag reclaimation and control technology, from three segments of the beef production process in China. From the farm to the slaughterhouse, electronic identification ear tag technology was used to identify the individual animal. From the slaughterhouse to the processing plant, gambrel identification was used to transfer the carcass information from the "old ear tag" to a "new ear tag". Last, gambrel RFID was converted to UCC/EAN-128 barcode labelling with a wireless electronic scale. The whole solution was evaluated successfully in Beijing.
