The Equine Science Program at Tarleton State University is dedicated to advancing knowledge across a broad range of equine-related disciplines. Faculty and students engage in research on topics including reproductive physiology, assisted reproductive technologies, nutrition, stress physiology, equine assisted services, exercise physiology, and other key areas impacting equine health and performance. The program emphasizes applied research and frequently collaborates with industry partners to ensure its work addresses real-world challenges in the equine industry. Through these efforts, the program contributes to both scientific discovery and the practical improvement of equine care and management.
