Comparison of Skeletal Muscle Citrate Synthase Activity Across Equine Breeds
Skeletal muscle citrate synthase (CS) activity serves as a marker for muscle oxidative capacity. CS activity was compared among Quarter Horses (QH), Arabians (AR), Thoroughbreds (TB), Standardbreds and Warmbloods at various ages and stages of training. Gluteus medius muscle biopsies were obtained at ages 6–23 m (n = 10), 2 y (n = 37), 3 […]
Feeding Performance Horses with Myopathies
In combination with exercise, nutrition is an essential component of managing horses with myopathies. The optimal feeding program for an individual is tailored to the diagnosis of a specific underlying myopathy. Exertional myopathies are defined by muscle pain and impaired performance during or after exercise. Exertional rhabdomyolysis (ER) represents a subset of exertional myopathies characterized […]
Heart Rate, Speed and Lactate During the Cross-Country Phase of an Advanced and CCI*** Three-Day Event
Performance in three-day event horses is influenced by the horse’s innate ability combined with its level of fitness. Heart rate (HR) and blood lactate have been routinely measured in laboratory settings to evaluate fitness and/or ability in horses. To investigate whether these measurements are useful in assessing performance during competition, 11 horses competing at the […]
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 […]
Nutritional Management and Feeding of Sick and Hospitalized Horses
When a horse arrives at a veterinary hospital, several nutritional or feeding challenges may be encountered. Feeding programs should aim to avoid weight loss, unless it is required for a specific condition (e.g., equine metabolic syndrome). Negative energy balance can lead changed intestinal microbiota, reduced immunity, and increased incisional complications. Some horses with peracute or […]
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 […]
