Abstract: The management of hormone-free reproduction in small dairy ruminant farming is a lever to be mobilized to respond to the challenges of agro-ecology and the evolution of societal demands. The Alpha-D® automated heat detector system remains to this day the only operational tool in sheep farms that allows artificial insemination without the use of hormonal synchronization. The introduction of such new tools implies change processes for the farms concerned. These changes may include biotechnical processes, at the herd level and/or surface management level. The objective of this thesis is double. On the one hand, it is a question of characterizing the processes by which conventional and organic farmers integrate the Alpha-D® device into their system and the implementation methods, taking into account changes in associated practices. On the other hand, the work aims to assess the sustainability of a diversity of systems (conventional and organic) that no longer use hormone treatments in their reproductive management. The comparison of the simulation results with the actors will make it possible to validate the most appropriate scenarios for implementing hormone-free reproduction according to the sectors and breeding systems tested within the Rayon of Roquefort area.
