The Effect of Long-Chain Omega-3 Supplementation on Blood Serum Gamma-Glutamyl Transferase (GGT) Levels and Inflammation Post-Exercise in Thoroughbred Racehorses

Horses supplemented with EO-3™ had significantly lower (p<0.05) GGT levels 2 and 4 hours post-exercise compared to the control horses. This may have resulted from a reduction in inflammation observed post-exercise in the horses fed EO-3. Open Technical Bulletin

Mineral and Vitamin Supplementation Including Marine-Derived Calcium Increases Bone Density in Thoroughbreds

Bone quality is important for the long-term health and soundness of performance horses. In racehorses, insufficient bone density is associated with shin soreness, an important cause of lost training time and reduced starts, as well as other aspects of bone fatigue. Risks of injury during training are associated with insufficient bone density. Research has previously […]

Effect of Omeprazole and Calcium Sources on Calcium Digestibility in Thoroughbred Horses

Equine gastric ulcer syndrome (EGUS) is very common, with a prevalence estimated from 53% to 93%. A major contributor to its pathogenesis is excessive gastric acid. Omeprazole (OM) is a proton pump inhibitor (PPI) that inhibits gastric acid secretion in horses and is the most popular treatment for EGUS. PPIs are also widely used in […]

A Marine-Derived Calcium Supplement Increases Bone Density in Thoroughbred Racehorses

Bone density and strength are important for the long-term health and soundness of performance horses.  Marine-derived calcium mineral complexes have been shown to improve bone density and strength in laboratory animals and humans. This study evaluated the effect of a supplement containing marine-derived calcium (Triacton™) (TA) on bone density in Thoroughbred racehorses.  Thirteen horses (average […]

Form of Alpha-Tocopherol Affects Vitamin E Bioavailability in Thoroughbred Horses

Vitamin E can be obtained from natural or synthetic sources, but the chemical structure of each is different. The following studies were conducted to determine if synthetic and natural-source vitamin E have similar bioavailabilities when administered at equal IU doses and to determine if water-dispersible forms of vitamin E are more bioavailable than lipid-soluble forms. […]

Fish Oil and Corn Oil Supplementation Affect Red Blood Cell and Serum Eicosapentaenoic Acid (EPA) and Docosahexaenoic Acid (DHA) Concentrations in Thoroughbred Horses

Horses require both omega-3 and omega-6 fatty acids in their diets. Long-chain omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are intermediate in the formation of eicosanoids that have been shown to reduce inflammatory responses, support immune function, and enhance fertility. This study was conducted to compare the effect of supplementation with oil […]
