Retirement Benefits for Racehorses: Understanding and Supporting Gut Health in Retirement
Start date
January 2026End date
January 2030Overview
British horseracing is committed to ensuring that racehorses can have a healthy retirement and second careers after their racing careers are over. Ensuring a healthy retirement is an important part of the sport’s social licence to operate. We know that in humans the gut microbiome changes significantly with age and can have a range of influences on health and quality of life. This project is designed to evaluate how the gut microbiome of racehorses changes with age and how this affects their welfare and their retraining for second careers. As part of this project, we will evaluate the potential impact of probiotic supplementation on gut health and on horse welfare.
Aims and objectives
- Characterise changes in the gut microbiome of retired racehorses up to 30 years old
- Describe associations between the welfare of horses undergoing retraining their gut microbiome
- Evaluate the effect of dietary probiotics on the gut microbiome and welfare of retired racehorses.

Professor Christopher Proudman
Professor of Veterinary Clinical Science
Biography
Chris Proudman graduated from Cambridge University Vet School in 1988 and was awarded a PhD in Equine Epidemiology from University of Liverpool in 1996. His academic career has embraced teaching equine medicine and surgery, equine intestinal disease research and various leadership roles at the University of Liverpool.
He has a long-standing involvement with the horseracing industry, including veterinary work on racecourses in Northwest England and membership of the Horserace Betting Levy Board's veterinary advisory committee.
Appointed as Head of the University of Surrey's new Vet School in 2013, he leads the development and delivery of a 21st century curriculum focussed on graduate confidence and competence, and on innovation in animal health.

Co-investigator
Professor Roberto La Ragione
Interim Pro-Vice Chancellor and Executive Dean for the Faculty of Health and Medical Sciences (FHMS), Professor of Veterinary Microbiology and Pathology
Biography
Roberto graduated in 1995 and then went on to study for a post graduate degree in veterinary microbiology at the Royal Veterinary College (University of London). In 1996 he moved to the government's Veterinary Laboratories Agency (VLA) to undertake a PhD on the pathogenesis of E. coli in poultry. On completion of his PhD studies, Roberto commenced a post-doctoral position at Royal Holloway, University of London, studying E. coli virulence factors and vaccine development.
Since 2001 his work has focused largely on the analysis of the colonisation, shedding and transmission of E. coli O157:H7 by all farmed animal species and he has led a number of commercial, Defra, research council (BBSRC, MRC, EPSRC, AHRC, Innovate) and EU projects in this area. He has published extensively in the area of host-microbe interaction with a particular emphasis on E. coli and Salmonella.
His current research interests focus on the pathogenesis of food-borne pathogens with a particular interest on AMR and the development of intervention strategies including vaccination, pre and probiotics for the control of bacterial pathogens such as Salmonella, Brachyspira and E. coli in food producing animals.
In 2005, Roberto was appointed Head of Pathogenesis and Control at the AHVLA and in 2010 he was appointed Professor of Veterinary Microbiology and Pathology at the University of Surrey. He gained the FRCPath in 2010 and in 2012 was appointed the Associate Dean for Veterinary Strategy in the new School of Veterinary Medicine at the University of Surrey. In 2014 he was appointed to the position of Head of the Department of Pathology and Infectious Diseases and Director of the Veterinary Pathology Centre. In 2019 he was appointed Deputy Head of the School of Veterinary Medicine at the University of Surrey. In 2021 he was appointed Head of the School of Biosciences and In 2024 Interim Pro-Vice-Chancellor and Executive Dean for the Faculty of Health and Medical Sciences.
He is the past president of the Med-Vet-Net Association and the Veterinary Research Club, the current Chair of the Humanimal Trust, a Trustee of the Houghton Trust, a member of the APHA Science Advisory Board, a member of the FSA ACMSF AMR sub-committee and the Chair of the Royal College of Pathologists Veterinary Pathology SAC. Roberto is an Associate member of the European College of Veterinary Microbiology and in 2020 he was awarded Honorary Associateship of the Royal College of Veterinary Surgeons. In 2023, Roberto was awarded the RCPath College Medal.
