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 […]

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 […]

The aim of this study was to gather information on feeding practices and to identify nutrient imbalances of racehorses in Turkey. A total of 134 racehorses who visited the Turkish Jockey Club Racecourse Equine Hospital in Istanbul were referred for professional nutritional advice in 2013. Each horse was examined, and body weight (BW), body condition […]

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 […]

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 […]
