Artificial intelligence on the one hand and animal welfare on the other are two very topical, forward-looking areas of research. At the IASP, we have been researching how to link the two areas for several years. Smart, sensor-based animal monitoring is a key technology for future-proof, sustainable animal husbandry in Germany. As part of a research contract, we have now developed innovative neural network structures for our corporate partner ESYS GmbH. The aim of this service was to make existing AI tools far more energy-efficient and faster by optimising and modernising them. This development now makes it possible to implement the calculation routines for evaluating animal welfare - based on physiological measurement data collected for each individual animal - directly on the microcontrollers of the animal sensors developed by the company.
