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 […]

Journal of Equine Veterinary Science. Volume 33, Issue 5, Pages 328–329. (Proceedings of the 2013 Equine Science Society Symposium.) Six fit Thoroughbred geldings (age 6.8 ± 1.2 y, […]

(International Conference on Equine Exercise Physiology 2014) Furosemide is widely administered to Thoroughbred and Standardbred racehorses to reduce the incidence and severity of EIPH. The magnitude and duration of mineral loss […]

Mesquita, V., Pagan, J., Valberg, S., Waldridge, B. and Whitehouse, C. (2014), Effect of Non-Structural Carbohydrate, Fat and Fiber Intake on Glycogen Repletion Following Intense Exercise. Equine Veterinary Journal, 46: 33. (International Conference on Equine Exercise Physiology 2014) Muscle glycogen is a potentially limiting substrate for horses during intense exercise. Low-starch, high-fat concentrates have become popular […]

In the process of extracting starch from corn for food manufacturing, the co-product corn germ dehydrated (AAFCO 48.32) is produced. This fraction is known commercially as Golden Max (GM). A study was conducted to investigate the nutritional value of GM for horses and compare it to the typical forms of processed corn commonly fed to […]

Muscle glycogen is a potentially limiting substrate for horses during intense exercise. Low-starch, high-fat concentrates have become popular for performance horses, but their effect on muscle glycogen usage and repletion is unclear. This study was conducted to evaluate the effect of nonstructural carbohydrate (NSC) intake on substrate utilization and glycogen repletion in Thoroughbreds during training […]

Commercial electrolyte products often contain dextrose, which is purported to improve electrolyte uptake in horses. Studies conducted at Kentucky Equine Research suggest that adding dextrose or starch to electrolyte mixes does not increase rate of absorption or retention of electrolytes, Dextrose may still have some value in improving the palatability of electrolyte mixes, but the […]

The aim of this study was to investigate the glucose dynamics in horses fed a high fat or moderate carbohydrate diet and to investigate if fish oil moderated these effects.

Low-carbohydrate diets are often recommended for horses with metabolic syndrome and high-fat diets are useful for managing horses suffering from RER and PSSM. It is questionable whether these types of diets are appropriate for normal, non-obese horses. This study was conducted to determine whether a moderate daily intake of carbohydrate from oats or a high […]
