Three methods for feeding visit construction out of HF RFID registrations were tested.
- class="label">•
The best method was a bout criterion equal to 10 s for two RFID tags per pig.
- class="label">•
Sensitivity was 83%, specificity 98%, accuracy 97% and precision was 75%.
- class="label">•
Performance tended to be lower when using one tag per pig.
- class="label">•
Observed feeding duration was well-correlated with RFID-based duration of visits.
