The purpose of this study was to determine the perception of sustainability among horse owners in the Netherlands and their willingness to switch to more sustainable feeding practices. A survey was distributed to a target group of horse owners in the Netherlands via social media channels. Data (n=338 valid responses) were stratified based on yard type and size (small (<20), medium (20-50), and large (>50 horses). Most of the yards were livery yards (68%) and they were small in size (66%). The term most commonly associated with sustainability was low environmental impact (61.8%). All participants (338/338) indicated that they were willing to switch to more sustainable feeding practices. Of the six options offered, the most popular was the use of plastic-free packaging products (60.5%). This study identified that numerically the greatest change in behavior for the Dutch equestrian community would be achieved by small livery yards (P < 0.001). The potential to modify certain practices might be limited by the size of the equestrian operation, such as the available land for altering pasture management, and the financial aspects of the enterprise. Future research should investigate how the scale and economic considerations of the equestrian business influence its capacity and willingness to adopt more sustainable feeding practices.
