Long-Term Measurement of Piglet Activity Using Passive Infrared Detectors

摘要

The activity of weaned piglets on a commercial farm was measured using passive infrared detectors during six breeding cycles. Highly heterogeneous daily behaviors were observed. A high level of movement was detected immediately after weaning, followed by a sudden drop and a subsequent stabilization throughout the cycle. The real series were best characterized by models with a single peak of activity.
