The Swiss Agroscope Institute, part of the Federal Office of Agriculture, is a driving force for sustainable development in the fields of agriculture, food and the environment, providing the scientific and technological basis for agricultural and environmental policy decisions as well as for the implementation of regulations.

As a collaborative representative of the Agroscope Institute, MSR has developed products that have been used in a variety of research, animal monitoring including breathing, walking, standing, lying and sleep behavior monitoring.

Cows expect to be well cared for. Are the cows in good condition? Are all the cows healthy? Are they kept in optimal conditions? In order to confirm the health status of the animals based on objective facts, the Agroscope Institute's Agrotechnology Department in Switzerland, together with the MSR team, equips the cows with the sealed and rugged MSR145 data logger.

How do I remember to chew?

The device is fixed to the hind legs of each cow and its three-axis accelerometer records the cow's movements. This method ensures that the animal's activity can be accurately monitored, allowing conclusions to be drawn about the cow's state of health, condition of life and the associated effects on milk production levels. Evaluation of the data can be carried out easily by computer.

About Regurgitation

Regurgitation[1]Recognized as an important, non-invasive, measurable parameter for early detection of ruminant metabolic disorders[2]The traditional ruminant sensors have some disadvantages when used in barn areas. Traditional ruminant sensors have had some drawbacks when used in barn areas. The new ART Ruminal Sensor consists of a nasal strip sensor, a liquid filled tube, a pressure sensor, a data logger and software for analysis.

The MSR data logger records the chewing movements of the cow and transfers the data to a computer via a USB interface. The R language based learning software combines the individual's mandibular movements[3]The ART ruminant sensors are suitable for research and consultation purposes. The results of the validation show that these devices are very reliable and the agreement between optical and automatic evaluation is very high. ART ruminant sensors are suitable for research and consulting purposes.
