Haylage is often fed to horses around the world and may be an appealing forage choice for certain horses due to its low dust content and lower NSC content when compared with hay of comparable species and maturity. The objective of this study was to determine if there were differences in digestibility and glycemic response […]

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 […]

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 […]

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 […]

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 […]

Joe D. Pagan, Ashlee Hauss, Alyx Swanhall, Emma Ford, Erica Rugg, Aline Bouquet, and Abby Pritchard Kentucky Equine Research, Versailles, Kentucky, USA   Water, hay, and feed intake was measured in 6 Thoroughbred racehorses (age 3.3 ± 0.5 y) (BW 468 ± 14.1 kg) for 56 d at a training center in Lexington, Kentucky, during […]

C. Whitehouse, J.D. Pagan, R.J. Coleman, Responses in fecal pH from low to high starch intakes in healthy horses. Journal of Equine Veterinary Science. Volume 33, Issue 5, Pages 358-359. (Proceedings of the 2013 Equine Science Society Symposium) Fecal pH is often used as an indicator of the hindgut environment. The relationship between cecal, colon […]

James, The effect of soaking or steaming timothy hay on voluntary intake and digestibility by Thoroughbreds. Journal of Equine Veterinary Science. Volume 33, Issue 5, Page 350. (Proceedings of the 2013 Equine Science Society Symposium) Three mature Thoroughbred geldings were […]

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 […]

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 […]
