Make a Difference for a Horse in Your Life - Take the 2014 CEH Survey on Performance Horse Management Practices

horseThe Center for Equine Health has developed a survey to better understand performance horse management practices and how they relate to musculoskeletal health and performance. If you are an owner of a performance horse (all disciplines), you can play a crucial role in this project by taking 10 minutes to complete this anonymous survey online. Once we identify trends in management practices and correlate them with health, injury and performance, we will target research to fill gaps in knowledge and establish science-based recommendations for equine athletes.
