Animal phenotyping has undergone profound evolution in recent years with the development of high-throughput equipment, increasingly non-invasive sensors, the rise of ”omics” technologies, and the use of artificial intelli- gence for image or sound analysis. The Phenotool platform has been developed with a twofold objective: 1) to present all the phenotyping equipment available within the LIPH4SAS research infrastructure; 2) to present the most important phenotyping tools available or under development for key traits related to the agroecological transition of livestock farming, mapped as part of a working group of the GIS Avenir Elevages, a French Think Tank dedicated to the future of livestock production Phenotool consists of a web interface (www.phenotool.fr), developed under WordPress CMS, which allows online consultation of a database containing the main informa- tion available on phenotyping equipment. It offers an advanced search system allowing users to filter equipment according to the species investigated, the traits to be measured, or the geographical location. It also provides detailed information on each instrument listed, such as its description, technical specifications, and specific training materials for each instrument. Phenotool aims to facilitate access to information in the rapidly developing field of livestock phenotyping. By promoting the sharing of resources and knowledge, it should contribute to the emergence of new collaborations and innovative projects.
