Oregon State University (OSU) researchers announced last month that they linked vesiviruses to abortions seen during Central Kentucky's bout with mare reproductive loss syndrome in 2001 and concluded that vesivirus-specific reagents should be included in the diagnostic panel for aborting mares. A University of Kentucky researcher disagrees with the findin...
Doctors at New Bolton Center's George D. Widener Hospital on Monday changed the cast on the hind right leg of Barbaro for the second time since the winner of the Kentucky Derby Presented by Yum! Brands (gr. I) was injured in the Preakness Stakes (gr. I) on May 20.
It's commonly known that racehorses endure extreme physical and mental stresses preparing for a racing career, which can lead to injuries and illnesses. In a University of Cambridge study, researchers sought to quantify ailments endured by today's racehorses.
The study followed 1,022 Thoroughbreds from conception to age four. Of those, 562 entered tr...
An outbreak of Equine Viral Arteritis has been confirmed at a New Mexico Quarter Horse farm, according to a release from the Reference Laboratory for Equine Viral Arteritis at the University of Kentucky College of Agriculture's Maxwell H. Gluck Equine Research Center.
A farm in northern New Jersey experienced high abortion rates in early June in fields where there were Eastern tent caterpillars.
University of Kentucky researchers studying Mare Reproductive Loss Syndrome are concerned that the results of a study by Oregon State University linking vesiviruses, which can affect a wide variety of mammals, to MRLS can be misconstrued.
A new study by veterinary researchers at Oregon State University has linked a major epidemic of abortion a few years ago in Kentucky Thoroughbred mares to infection with vesivirus, the first time the virus has been suggested to cause this type of problem in horses.
The excitement of the upcoming third jewel of the Triple Crown highlights the shining careers of Thoroughbreds in their prime, but also conjures up the tender subject of what might happen to those runners once their careers have ended.
Barbaro, winner of the Kentucky Derby Presented by Yum! Brands (gr. I), continues to improve daily as he recovers from a shattered hind leg sustained at the Preakness on May 20. "I'm very pleased with the progress Barbaro is making," said chief of surgery Dean W. Richardson. "Everything is fine."
With their shaggy manes and stocky bodies, they look like children's pets. They are the kind of animals that make people coo and exclaim, "How cute!" But the semi-feral ponies that roam the spacious pasture at the University of Pennsylvania's New Bolton Center (NBC) are the subjects of serious scientific research.
"A lot of the equipment you see on the television show 'ER' we have here," says Dr. Jon Palmer, an associate professor of medicine and the director of the center's neonatal program. "We have respirators, heart monitoring equipment, blood pressure monitoring equipment, and equipment that monitors exhaled gasses. We even have a defibrillator. I only wish I could get blood gasses as fast as they do on 'ER.' "
As mentioned in previous articles, Barbaro may be susceptible to other complications during his recovery because of the severity of his injury. According to veterinary surgeon Dean Richardson, horses in his case are particularly vulnerable to laminitis or other problems in the opposite foot.
Dr. Rick Arthur has been named equine medical director for the California Horse Racing Board and will advise the board on all matters relating to equine health and welfare and drug testing.
At its annual board meeting May 13, Thoroughbred Charities of America (TCA) approved grants of $1,750,000 to 136 non-profits, representing equine rescue/retraining, backstretch/jockey, research, education scholarships, and therapeutic riding facilities in 35 states.
In October 1987, Walmac International and its veterinarians went to extensive lengths to save the life of stallion Nureyev. Those efforts paid off, adding 14 years to the horse's life. When the son of Northern Dancer died this past Oct. 29 at age 24, he had been represented by 130 stakes winners. This article detailing how Nureyev was saved in 1987 was originally published in the Oct. 10, 1987 Blood-Horse.
Britain's Levy Board has committed 1,780,000 pounds over the next three years to veterinary research projects, including new studies into a greater understanding of the causes of joint injuries and fractures.

Musculoskeletal injury is the main cause of wastage in Thoroughbred racehorses worldwide, with nearly 30% of all fractures being pelvic and tibial stress fractures. California studies in the late 1990s suggested fast work increased the risk of injuries, while Kentucky studies implied high-speed exercise was protective. K.L.P. Verheyen, DVM, MSc, PhD, M...
Your horse's feet are some of the most important structures contributing to his performance ability, and most people do what they can to keep them healthy. Unfortunately, things can and do go wrong with your horse that can cause hoof cracks to form. Maybe he pulled a shoe in the pasture or grabbed his heel during a competition. Perhaps conditions have...

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...
