The storage telemetry system ETHOSYS can be applied to measure daily patterns of activity and grazing in larger mammals over complete years. The application of this system will be described and practically demonstrated.

Movements of a body or single extremities can be recorded by a the three-dimensional acceleration measurement system WAS in humans and animals. From the three dimensional accelerations, the resulting force can be computed with a high temporal resolution. The possibilities of the system will be demonstrated and compared to ETHOSYS.

From both systems, time series are produced. Like these time series can be analysed by frequency analysis, will be demonstrated based on the program TIME. The results of frequency analyses can be used to distinguish normal and disturbed time patterns on a daily to hourly scale for behaviour patterns as well as on a scale of milliseconds for movements. It will be demonstrated, how welfare, different diseases, or stress can be detected and distinguished. From the WAS data, a lameness detection procedure will be demonstrated. The visitor will be trained in the application of the measurement systems and the software for biorhythmic analysis. Users will learn for which kind of behaviour analysis the two systems can be applied.
