Thoroughbred Racehorses in Hong Kong Require Vitamin D Supplementation to Mitigate the Risk of Low Vitamin D Status
Vitamin D biology in equids is unique and poorly understood. Naturally managed (grazing) horses rely on dietary vitamin D2 (ergocalciferol) to provide adequate vitamin D, because endogenous ultraviolet radiation-mediated synthesis of vitamin D3 (cholecalciferol) is ineffective in this species. To test the hypothesis that the management of stabled, nongrazing racehorses is a risk factor for […]
Omeprazole Reduces Calcium Digestibility in Thoroughbred Horses
Proton pump inhibitors like omeprazole reduce nutrient digestibility in humans. This study determined the effect of omeprazole on the digestibility of diets containing limestone or marine-derived calcium (BMC) and to assess changes in blood parameters associated with gastric acid production and calcium status in horses. Thoroughbreds were used to evaluate the digestibility of diets containing […]
A Supplement Containing Marine-Derived Minerals Increases Bone Density in Thoroughbred Racehorses in Early Training
Bone density and strength are important for the long-term health and soundness of performance horses. Marine-derived mineral complexes improve bone density and strength in laboratory animals and humans. Additionally, nutrients without established requirements in horses, such as boron, silicon and vitamin C, may affect bone health. This study evaluated the effect of feeding a supplement […]
Omeprazole Reduces Calcium Digestibility in Thoroughbred Horses
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 humans to treat acid-related conditions and have been associated with a reduction in the digestibility of several nutrients, including protein, fat, calcium (Ca) and iron. This […]
A Comparison of the Nutrient Composition of European Feeds Used at the 2010 and 2018 FEI World Equestrian Games
Held every four years since 1990, the FEI World Equestrian Games (WEG) are the major international championship for eight equestrian disciplines. Although the 2010 and 2018 editions of WEG took place in the U.S., the majority of the horses competing came from Europe and were fed feeds made by European manufacturers. In 2010, Kentucky Equine […]
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 […]
Nutrient Content of Australian Horse Pastures—Effect of Season
Most Australian horses rely on pasture for some of their nutrient intake, and many are just on pasture without supplementary feed for some part of the year. To determine the nutrient intake of horses on pasture for comparison with recommended daily allowances, nutritionists need to know not only the pasture intake but also the nutrient […]
Nutrient Content of Australian Horse Pastures—Nutrient Intakes Compared to Requirements
Most Australian horses rely on pasture for some of their nutrient intake, and many are just on pasture without supplementary feed for some part of the year. To determine the nutrient intake of horses on pasture for comparison with recommended daily allowances, nutritionists need to know not only the pasture intake but also the nutrient […]
Dextrose Does Not Affect Rate of Absorption or Retention of Electrolytes in Idle Thoroughbreds
Two studies were conducted to evaluate the effects of dextrose or corn starch on uptake and retention of electrolytes and water in idle horses. In study 1, four Thoroughbreds (age: 6.25 ± 2.25 y; BW: 574.4 ± 82.4 kg) were used in a 4×4 Latin square trial. The horses were dosed with 92 g of […]
Furosemide Administration Affects Mineral Excretion and Balance in Non-Exercised and Exercised Thoroughbreds
Two studies were conducted to measure the effect of furosemide on 72-hour digestibility and urinary excretion of calcium (Ca), phosphorus (P), magnesium (Mg), sodium (Na), potassium (K), and chloride (Cl) in nonexercised and exercised mature Thoroughbred geldings. In study 1, total fecal and urinary mineral excretion was measured in three unexercised Thoroughbred geldings for 72 […]
