Flock Nocturnal Activity: Is There a Rotative Guard?

Animal activity during the night period is of enormous importance, since it represents approximately half animals’ lives, and monitoring this makes possible to detect problems related well-being safety, allows us infer energy expenditure on basis their level. The present study analyzes a sheep dataset created validate non-invasive techniques that can be used at abnormal nocturnal activity. allowed cyclic changes in period, which composed inactive active periods, identify lying positions. analysis joint flock perceive time lag rest cycles, consisted periods ewes undone between elements flock. Although does not allow components inactivity, method monitor brain activity, results confirm cyclical character has been reported literature, as well typical posture when down. an exploratory application with very small number animals, similarity obtained documented existing have mostly using invasive methods, encouraging, suggests rely processes based inertial sensors.
