Despite the range of oral joint supplements available, there has been very limited research into their efficacy.
Aim: To determine effect of an oral joint supplement on orthopaedic, physiotherapy and handler evaluation in horses.
Methods: 24 mature horses were included in the study. Horses were excluded if they were in poor body condition, had health problems or greater than 2/5 lameness. Supplement Sa (containing chondroitin sulphate 1.62g/100kg, glucosamine 1.9g/100kg, vitamin C 0.8g/100kg, methyl sulphonyl methane 2.56g/100kg, DHA 0.66g/100kg), EPA 0.34g/100kg or placebo P (carrier/flavours only) were given to horses in their feed for 21 days each in a triple-blind crossover design; all horses received supplement and placebo in random order. Horses were evaluated at day 0 (baseline), 21 (after first treatment) and 42 (after second treatment). Assessments included: Clinical orthopaedic evaluation for straight line and lunging circle (walk and trot), and during ridden exercise (walk, trot and canter); Handler field evaluation, during groundwork and while ridden, grading specific criteria; Grading of range of motion (ROM) and muscle tone based on standardised physiotherapy criteria. All evaluators were blinded to treatment. Significance indicates P <0.05.
Results: S was associated with significantly lower lameness grade in a straight line and circle than either P or baseline. Both S and P were associated with significantly improved ROM and muscle tone over baseline. Handler scores for ridden and groundwork were significantly higher with S compared to P or baseline. After S, horses were graded significantly higher for field ‘ease-of-movement’ compared with P or baseline.
Conclusions and Practical Significance: Oral administration of this supplement was associated with less lameness, improved ridden/groundwork scores and improved ‘ease-of-movement’ in the field. Improvement in physiotherapy assessment with both treatments over time suggests effects of ongoing training on ROM and muscle tone. Acknowledgements: World Horse Welfare.
