Decision support tools for grass-based fodder management on Walloon dairy farms: current adoption and perspectives

Description of the subject. Many decision support tools (DSTs) have been developed to help dairy farmers optimally manage the high variability in the quality and availability of grass-based fodder, but their adoption rate remains low. Objectives. The objective was to characterize and understand the adoption rate of DSTs related to using grass-based fodder. Methodology. A sample of 61 Walloon (Belgium) dairy farmers responded to an online survey concerning their current use of 23 DSTs related to using grass-based fodder either directly (pasture or grassland) or indirectly (feeding or techno-economic), as well as barriers to and incentives for adopting them, their current interest in DSTs, and satisfaction with the guidance on using these DSTs. Results. Pasture management DSTs were used the least, even though farmers were the most interested in them. Farmers used simple indicators rather than software or automated tools. Farmers indicated that DSTs were too expensive and time consuming, even if they could ultimately save them time and money. Continuing education is lacking. Four types of users were identified who influence the use of DSTs: high user no grazing (H-NG), high user traditional or technical grazing (H-T/TG), low user traditional grazing (L-TG), and moderate user organic (M-ORG). Conclusions. Communicating with end-users during each step of DST development would help (1) identify the specific needs of a diverse set of dairy farmers and (2) develop DSTs that better correspond to their practices. More long-term guidance is required to inform farmers about existing DSTs and to transfer the knowledge required to use them. Outils d'aide à la décision pour la gestion des fourrages herbagers dans les exploitations laitières wallonnes : adoption et perspectives Description du sujet. Afin d’optimiser la gestion des fourrages herbagers par les éleveurs laitiers, de nombreux outils d'aide à la décision (OAD) ont été développés mais leur taux d'adoption reste faible. Objectifs. L'objectif était de caractériser et comprendre le taux d'adoption des OAD liés à la valorisation des fourrages herbagers. Méthodologie. Un total de 61 éleveurs laitiers wallons (Belgique) ont répondu à une enquête en ligne concernant l’utilisation de 23 OAD en lien avec la valorisation des fourrages herbagers de manière directe (pâturages et prairies) ou indirecte (alimentation et gestion technico-économique) ainsi que sur les freins et les leviers, leurs intérêts et leur satisfaction
