Musculoskeletal injury is the main cause of wastage in Thoroughbred racehorses worldwide, with nearly 30% of all fractures being pelvic and tibial stress fractures. Studies in California in the late 1990s suggested fast work increased the risk of injuries, while other studies in Kentucky implied high-speed exercise was protective. K.L.P. Verheyen, DVM, MS...
A study that will research the efficacy of aminocaproic acid and conjugated estrogens as treatments for the prevention of exercise-induced pulmonary hemorrhage (EIPH) in horses has been selected to receive a one-year, $75,000 grant.
An Australian researcher says he's found a reliable way for trainers to monitor Thoroughbred racehorse fitness using global positioning system (GPS) technology measurements of velocity and heart rate during fast gallop training routines. He presented the study at the 2005 American Association of Equine Practitioners Convention, held Dec. 3-7, 2005, in Sea...
University of Wisconsin researchers found certain forelimb characteristics in growing Thoroughbreds are associated with higher birth weights, and their carpal (knee) conformation is associated with the parents'. Both genetics and environment affect forelimb conformation.
An Australian survey found that euthanasia for catastrophic forelimb injury was the most common Thoroughbred racehorse fatality. Also, sudden death (not as the result of euthanasia) contributed more to racing fatalities than previously thought. Analyzing point-of-death blood samples could help scientists better pinpoint the triggers of sudden deaths.

Inconsistencies in racetrack surfaces account for a large number of lamenesses in racehorses, said Jeff Blea, DVM, of the Southern California Equine Foundation in Arcadia, Calif., during the Lameness in Racehorses Forum held at the 51st Annual AAEP Convention, in Seattle, Wash., Dec. 3-7, 2005. "Even though they are at the same track, the consistency of t...
A racehorse running at top speed breathes about 120 times per minute, moving about 12-15 liters of air per breath or 1,400-1,800 liters per minute. With this amount of airflow, it's not hard to imagine that any amount of airway inflammation can significantly affect performance. Unfortunately, the problem is common in horses, said Susan J. Holcombe, VMD, P...

Straight conformation in the forelimb doesn't necessarily beget a more successful racehorse. This is what a research group from the University of Wisconsin's School of Veterinary Medicine discovered in a recent study. However, the group also determined that certain forelimb deviations have a negative effect only on horses' 2-year-old race records.
University of Wisconsin researchers have shown that certain forelimb characteristics in the growing foal are associated with higher birth weights, and a foal's carpal (knee) conformation is associated with the carpal conformation of both of its parents. Additionally, they implicate both genetics and the environment in the forelimb conformation of a Thorou...
