Disease management in animal production is essential and requires comprehensive data integration. An ontology is a means of organizing knowledge and represents a set of concepts with logical relationships between them. The Animal Health Ontology for Livestock (AHOL), developed by INRAE, provides a standardized framework for organizing farm animal health traits. AHOL categorizes diseases, symptoms, affected species and pathogens, promoting interoperability and facilitating knowledge sharing. This article presents the development of AHOL and its possible application in the rabbit sector. AHOL offers a valuable resource accessible on its website with data on 60 rabbit diseases, their symptoms and pathogens: https://www.umrh.inrae.fr/ontologies/visualisation/public/ahol/diseases/show. Each of these elements is classified in a tree structure to facilitate the search and organization of information. Ongoing evolution and collaborative efforts are essential to the continuous improvement of AHOL and the extension of its application to animal health management. This tool can be used by professionals or students in animal health, as well as by all scientists or professionals working with farm animals.
