Modelling the Long-Term Consequences of Implementing Hormone-Free Reproductive Management on the Sustainability of a Dairy Sheep Farm

•A multi-agent dairy sheep farm simulation model, called REPRIN’OV, is proposed.•REPRIN’OV simulates impacts of hormone-free (HF) reproduction in dairy sheep farms.•Several indicators of farm sustainability are specifically simulated by REPRIN’OV.•HF scenarios were tested for a conventional farm and simulation results analysed.•REPRIN'OV is a tool to design new sustainable HF strategies for dairy sheep farms.
