Geneticists have disclosed the findings of a six-year study which, as well as discovering discrepancies in the stud book, for the first time details a direct correlation between specific genes and aspects of racing performance in Thoroughbreds.
An Arabian mare in Marion County, Florida, aborted a 310-day gestation (the foal was born dead) on March 13 that was confirmed as having mare reproductive loss syndrome (MRLS), according to Dr. Dana Zimmel, of the University of Florida's College of Veterinary Medicine.
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.
In an effort to control the spread of Equine Herpes Virus Type 1 (EHV-1) after consulting with the Kentucky State Veterinary Office and the Kentucky Horse Racing Authority, Keeneland will require several conditions to be met for a horse to enter its stable areas.
The Delaware Thoroughbred Racing Commission endorsed a plan Friday to implement testing for the presence of alkalizing agents - or "milkshakes" - in racehorses during the 2006 Delaware Park season.
The Maryland Department of Agriculture has lifted the hold order on Barn A at Pimlico Race Course after 21 of the 25 horses in the barn tested negative for equine herpesvirus.
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...
Exercise-induced pulmonary hemorrhage (EIPH), or bleeding in the lungs after exercise, costs the United States horse racing industry a great deal--estimated at up to $260 million per year by Kenneth W. Hinchcliff, BVSc, MS, PhD, Dipl. ACVIM, of The Ohio State University. During his presentation at the American Association of Equine Practitioners Conventio...
Maryland officials reported Wednesday that a horse which tested positive for equine herpesvirus type-1at Fair Hill Training Center in Cecil County, Md., last week, has recovered from its fever and has shown no signs of neurologic illness.
A Colorado State University (CSU) researcher recently reported that he and his colleagues have found significant patterns of six different signals of damage or "biomarkers" in the serum of racehorses with certain musculoskeletal diseases. This means veterinarians are much closer to being able to anticipate the injuries or problems a horse might ...
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...
An Australian researcher reported 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 normal fast gallop training routines. David Evans, BVSc, PhD, associate professor in the Faculty of Veterinary Science at the University of Sydney...
The Kentucky Horse Racing Authority, acting on advice from the Equine Drug Research Council, unanimously approved medication withdrawal guidelines and threshold levels at a special meeting Feb. 10.
In light of recent outbreaks of the equineherpes virus (EHV-1) and the Feb. 13 opening of most Central Kentucky breeding sheds, the Kentucky Thoroughbred Farm Managers Club held a discussion at its Feb. 9 meeting on how best to prevent the spread of the virus.
