  1. Administering Hyaluronic Acid to Performance Horses Karey L. McPhee December 4, 2008 ANSC 590

  2. Performance Horses • Racing, endurance, cutting, rodeo, etc… • Susceptible to joint issues like any athlete • Weight vs. Joint Size • Success administering H.A. for joint problems • Essential for joint health • Bodies produce less H.A. after 4 years old (Engstrom-Laurent, 1989) • OCD, DJD, Epiphisitis, Arthritis

  3. Healthy Joints

  4. Hyaluronic Acid • Ubiquitous in vertebrates • Naturally occurring • Sodium Hyaluronate • Combined with blood plasma  synovial fluid (Nizolek and White, 1981) • Lubricates joints • Highly viscous • Provides nutrients to cartilage and surrounding tissues

  5. Three Common Administration Methods

  6. Direct Injection • Draw out existing fluid and inject: • HA • Legend (Bayer) • Cortisone • Polysulfated Glycosaminoglycans (PSGAGs) • Adequan (Luitpold) • Invasive • Downtime • Expensive • Destructive? (Treiber, 2007) • Masks problem • Pierce, 2003 suggests HA goes elsewhere

  7. Intravenous Injection • Maintenance practice • Distributed via blood • Circulating H.A. lasts 2-3 days (Pierce, 2003) • Painful • Invasive • Expensive • IV Legend $25/shot • Not as effective as oral H.A. to increase H.A. serum levels (Pierce, 2003)

  8. Oral Administration • Several Forms • Powder • Easiest to administer • Gel • Cost effective • Nutraceutical/mineral package • 1-3 days as needed • Non-invasive • More effective method for maintaining H.A. serum levels (Pierce, 2003)

  9. Prevention!!!!! • More cost effective to prevent joint issues rather than treat • Best way to prevent • Oral H.A. • Consistent • Increase performance • Horses “protect” themselves • Pain decreases performance • Maximize days in training • Less days out due to soreness • On average 5 more days in training (Pierce, 2003) • Extend competitive career • Sound horses last longer!
