This study aims at assessing the socio-economic impacts of alternative practices to control Gastro-Intestinal Nematodes (GIN) in French dairy goat farms based on a farm modelling and a participatory approach. The Structured-Decision-Making approach (SDM) was used to guide focus group discussions with farmers and technical advisers. We observed an increased gross margin of €41 per dairy goat when implementing the alternative GIN control practices, which was mainly due to a decrease in the milk withdrawal cost. The adoption of more targeted and strategic treatments was positively linked to the ease of implementation, the manager’s experience, as well as alignment with core beliefs
