For decades, horse owners followed routine rotational deworming schedules. That approach fueled drug resistance in equine parasites, leaving fewer effective options today. Smarter management now relies on testing, timing, and targeted treatment.

In this episode of Equine Innovators Dr. Martin Nielsen, professor of equine clinical sciences at Aarhus University, in Denmark, shares insights from decades of research that shaped modern parasite control. He explains why elimination of equine internal parasites is not possible, what mistakes owners still make, and how veterinarians and farm managers can adapt their programs.

From tapeworms in adult horses to ascarids in foals, Nielsen outlines today’s biggest concerns and the evidence-based strategies that help preserve drug efficacy for the future. He also previews emerging diagnostic tools that could transform parasite management in the years ahead.

Tune in to learn how science-driven parasite control protects horses’ health and keeps deworming drugs effective for the next generation

In this episode of Equine Innovators, host Stephanie Church talks with Dr. Lori Bidwell—board-certified veterinary anesthesiologist and co-founder of East West Equine Sports Medicine—about how veterinarians use sedation to keep horses and handlers safe during procedures. Bidwell explains the difference between sedation and general anesthesia, offers examples of standing surgeries that once required full anesthesia, and shares how Dormosedan Gel has changed how owners manage stressful situations such as clipping or fireworks. She also offers practical tips on safety, storage, and monitoring, and describes recent innovations and where sedation practices are headed in the years to come.

As horse owners, we might not think about how research in humans can help horses, and vice versa. Carrie Shaffer, PhD, of the University of Kentucky ’s (UK) Department of Veterinary Sciences and the Gluck Equine Research Center, is working at the interface of human and equine medicine, creating tiny models of horses’ body systems to better understand how we can prevent and fight equine disease, and help body processes such as wound repair and tissue healing.

About the Expert: Carrie L. Shaffer, PhD, is an assistant professor in the University of Kentucky’s (UK) Department of Veterinary Sciences and the Gluck Equine Research Center. She holds joint faculty appointments in the UK College of Medicine (Department of Microbiology, Immunology, and Molecular Genetics) and the UK College of Pharmacy (Department of Pharmaceutical Sciences). Shaffer is a graduate of the UK College of Agriculture (BSc) and Vanderbilt University (PhD), and she completed National-Institutes-of-Health-funded postdoctoral fellowships at Vanderbilt University Medical Center and the California Institute of Technology. An expert in host-pathogen interactions and microbial pathogenesis, her research interests include understanding mechanisms underlying equine infectious disease using novel in vitro biomimetic models. One major focus of the Shaffer Lab is developing an innovative “horse-on-a-chip” microfluidic platform and diverse equine organoid model systems to enable investigations that address fundamental questions in equine infectious disease, therapeutic and vaccine development, allergic and immune-modulated conditions, tissue remodeling in response to injury, developmental and reproductive biology, and the identification of genetic factors that determine disease outcome in the horse.

As horse owners, we have our rhythms and routines around the barn. But why do we do farm chores the way we do them, and could we—and our horses—benefit from changing our approaches? Steve Higgins, PhD, the director of Animal and Environmental Compliance for the University of Kentucky’s (UK) Agricultural Experiment Station, in Lexington, describes ways horse farm owners and managers can optimize daily horse farm tasks for efficiency, cost-savings, and environmental soundness.
