to the animal like a commercial identification tag. Thus, identification is possible without much effort. It can also be used to collect data such as medical history or relocation can be recorded. Additionally, this allows, for example, the preservation of groups in which a stable hierarchy has been established. Currently, once the animals are pregnant, they are placed in individual pens and then randomly grouped again. This has the consequence animals fight among themselves and are exposed to massive stress over a long period of time. This affects the ability to give birth to offspring, reduces the lifespan or general health and feed conversion. In addition, more effective climate regulation can occur by regulating by body temperature rather than room temperature. Energy savings are possible and technical problems are immediately identified. Moreover, we are currently working on predictions for optimal fertilization times and births. Fertilization timing is essential because even with successful fertilization, optimal timing results in a larger litter.

Births are additionally an important event where intervention is occasionally needed. In case of complications, interventions by barn workers are necessary, but in practice they are rarely take place, since observation is possible only by physical presence. Our system as a whole offers an easy-to-install/plug-and-play platform that requires almost no user input. An ear tag has to be tagged with an NFC-enabled device via our APP with any ID, for example the internal ID system can be used – nothing more is needed. The assignment to the user takes place exclusively in the background. All this data and sensor data is displayed in our app and can also be shared with external providers such as the usual management systems via API. Our sensor brand has already been tested hundreds of times and is in the third revision, which reduces the lifetime and failure rate massively improved. We are already at a practical application of over a year with our oldest customers/innovators.
