Bone density and strength are important for the long-term health and soundness of performance horses.  Marine-derived calcium mineral complexes have been shown to improve bone density and strength in laboratory animals and humans. This study evaluated the effect of a supplement containing marine-derived calcium (Triacton™) (TA) on bone density in Thoroughbred racehorses.  Thirteen horses (average […]

Pagan1, Peter Kazakevicius2, Alyx Swanhall1, Emma Ford1, and Abby Pritchard1 1Kentucky Equine Research, Versailles, Kentucky, USA; 2 Ocala, Florida, USA Radiographic photodensitometry to estimate bone density in horses was originally developed using conventional analog film radiography. Today, most researchers have switched to digital radiography (DR) to make these measurements. One important feature of […]

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 […]

Joe D. Pagan1, Emma Mulvey1, Kathleen O’Neill1, Natalie Ireland1 and Mike Davies2, 1Kentucky Equine Research, Versailles, Kentucky, USA; 2ClockItEQ, Ltd., Perth, Western Australia Nutrient requirements for performance horses are dependent on the intensity and duration of exercise during training and competition. Differences between racehorses and upper-level event horses have not been previously defined. This study […]

Joe D. Pagan1, Kathleen O’Neill1, Natalie Ireland1, and Mike Davies2 1Kentucky Equine Research, Versailles, Kentucky, USA; 2ClockItEQ, Ltd., Perth, Western Australia Presented 25th Symposium of the Equine Science Society, 2017 Training protocols should be designed taking into account the intensity and duration of exercise during competition. This study measured heart rate (HR), duration, speed, and […]

Genetically modified (GM) crops represent an important segment of worldwide agriculture, as evidenced by the amount of land used to cultivate them and their widespread use in both human and animal industries. Genetic modification allows desirable traits to be imparted to plants, primary of which are insect resistance (Bt technology) and herbicide tolerance (Ht or […]

(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 […]

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 […]
