Abstract
The agroecological transition of livestock systems, by turning its back on the simplification and artificialisation of practices and by relying on natural processes that are more complex to manage, requires the integration of a more extensive range of information than in conventional management methods. Consequently, the agroecological transition of livestock systems requires the development of devices (equipment, platforms, etc.) that allow practitioners to be better informed to support decision-making. This section presents work on devices invented in laboratories and research stations, not all of which were a priori intended to become an innovation. This work focuses mainly on the first stages of the path from invention to innovation, from the design of prototypes and the definition of their use by end users to a finished product, sometimes accompanied by a patent application
