Miriam Engel, an agricultural sciences student at Christian-Albrechts-Universität zu Kiel, is currently writing her Bachelor’s thesis at the Institute of Animal Breeding and Husbandry in collaboration with the Holsteiner Verband. The thesis focuses on the information resources available to Holsteiner horse breeders when making mating decisions. At the heart of the thesis is a survey specifically aimed at Holsteiner horse breeders. Active participation is essential for the subsequent analysis. The survey takes approximately 5–10 minutes to complete. You can access the survey via the following link: https://www.survio.com/survey/d/C5K4S7G6D5O1K7R4C
