The future of equine health is being shaped by research that not only aims to improve the lives of horses but also contributes to a broader understanding of human health. At the University of Surrey, this work is guided by a One Health, One Medicine approach, which recognises the close relationship between animal health, animal welfare and human wellbeing.
Researchers believe that studying diseases, disorders and injuries in animals can provide valuable insights that help improve healthcare for people. Equine health has become a particularly important area in demonstrating how this approach can deliver benefits across species.
Understanding Equine Heart Health
One area receiving significant attention is equine cardiology. Researchers are investigating heart conditions in horses, including cardiac arrhythmias, to better understand why some racehorses collapse during or after races.
Exercise-associated sudden death in racing horses remains difficult to predict and has serious consequences for both the animals and the racing industry. Current research seeks to identify cardiac factors linked to these incidents and to develop methods for recognising horses that may be at risk.
The findings could have wider significance beyond equine medicine. Although sudden heart-related collapses in elite human athletes are uncommon, horses provide a valuable model for understanding how highly trained hearts respond to intense physical demands. Greater knowledge of equine rhythm disturbances may help researchers improve understanding of similar conditions in people.
Using Technology to Advance Research
A major milestone was achieved when a horse named Ted's Friend became the first horse to wear a heart monitor during a race on a British racecourse. Working in partnership with the British Horseracing Authority, researchers collected real-time cardiovascular data during competition.
The information gathered is helping researchers better understand factors associated with exercise-associated sudden death. The project also highlights the importance of collaboration between academic researchers and industry partners.
Researchers have also explored the use of artificial intelligence in equine health. A newly developed tool can identify horses that may be at risk of developing atrial fibrillation, a common heart rhythm abnormality.
This work builds upon an earlier machine-learning innovation that analyses electrocardiograms from horses and detects heart rhythm disorders. The technology has the potential to be incorporated into veterinary ECG devices and may also offer future applications in human healthcare.
Exploring the Genetics of the Equine Heart
Research is also examining the genetic foundations of cardiac function in horses. Scientists are mapping genes and proteins involved in controlling heart rhythm in both healthy and diseased hearts.
By studying differences in gene and protein expression across heart chambers, researchers aim to better understand the biological mechanisms responsible for electrical conduction and muscle contraction.
International collaboration has enabled the collection of samples and clinical data from multiple countries, helping to expand the research programme. These genetic studies complement ongoing investigations into how horse hearts adapt to extreme exercise.
Because horses can tolerate a wide range of heart rates and share similarities with humans in certain heart conditions, this research may eventually contribute to improved screening and prevention strategies for sudden cardiac death in human athletes.
The work has already attracted further support, allowing researchers to extend aspects of their investigations from horses to human patients.
The Importance of Gut Health in Foals
Alongside heart research, gut health has become another major focus within equine health studies.
Research involving Thoroughbred foals examined how bacterial diversity in the gut during early life relates to later health and racing performance. Scientists analysed 438 faecal samples collected from 52 foals and monitored their health from birth until three years of age.
The study considered respiratory, gastrointestinal, orthopaedic and soft-tissue conditions alongside race performance indicators such as finishing positions, official ratings and prize money.
The findings showed that foals with more diverse bacterial populations at one month of age generally experienced fewer health problems and achieved stronger racing outcomes later in life. Specific bacterial groups were also associated with improved race performance measures.
The Impact of Early Antibiotic Use
Researchers also investigated the effects of antibiotics administered during the first month of life.
Foals that received antibiotics showed lower levels of bacterial diversity and later earned less prize money. They were also found to have a greater likelihood of developing respiratory disease as they matured.
These results highlighted the importance of maintaining healthy gut bacterial communities during early development and demonstrated how early-life factors can influence future health and performance.
Future Developments in Equine Health Research
Building on these findings, work is underway to develop probiotics designed to support gut health in foals. Researchers are also seeking ways to use antibiotics while minimising their impact on beneficial bacterial populations.
Further studies are examining relationships between gut bacteria and the respiratory tract, as well as investigating biomarkers linked to equine grass sickness, a severe neurodegenerative disease that predominantly affects grazing horses.
These projects form part of a broader effort to improve horse health, welfare and long-term outcomes through evidence-based research.
Looking Ahead
The future of equine health is being shaped by advances in heart monitoring, artificial intelligence, genetics and microbiome research. Together, these developments are helping researchers better understand disease, improve animal welfare and enhance veterinary care.
At the same time, the knowledge gained from studying horses is contributing to a wider understanding of human health. Through the One Health, One Medicine approach, equine health research continues to demonstrate how progress in veterinary science can benefit both animals and people.
As research continues to evolve, the future of equine health remains focused on improving the lives of horses while generating insights that may influence healthcare far beyond the stable.
