It was demonstrated in several driving experiments with cattle and pigs that flexible UHF transponder ear tags are generally suitable for use in simultaneous detection of transponders in cattle and pigs.
Furthermore, it could be proved that driving experiments are suitable and necessary to test UHF transponder ear tags in practice.
and durable UHF transponder ear tags were found in the cattle experiments. Regarding the further development of the transponder ear tag types, it was shown that thecorrect de tuning of a transponder results in a clear improvement in the results and an improvement in the detection reliability.
A reading rate of 100% could be reached in the pig experiments, but the transponder ear tags need to be reduced in size and improved in robustness and durability to keep their functionality during the whole lifetime of the pigs.
The label and antenna material is a decisive factor for the success of the grouting process of the ear tag.
Since the grouting directly in fluence the protection of the transponder by the ear tag material, the durability of the ear tag also depends on the foil material which has to be chosen carefully. In the present experiments, polyimide foil seems promising
