In her presentation “Enlarged Superficial Digital Flexor Tendons in Immature Th...
The number of 2002 foals nominated to the Breeders' Cup program is down 8% from last year, largely due to mare reproductive loss syndrome, which resulted in the loss of nearly 20% of the pregnancies of Kentucky-based mares when it swept through the region in the spring of 2001.
By Jenny Taylor -- The culprit for MRLS was an unseasonable weather-induced pasture change, which caused pregnant mares to have an acute nitrogen overload, and subsequent ammonia-induced abortions.

Few dispute that nutrition is important for athletic performance in racehorses. However, I'd wager that there is much less agreement among horse owners, nutritionists, and veterinarians when asked to expound upon the "nitty gritty" of what works (and what doesn't) when feeding a horse in race training. Some focus on the virtues of the latest fad supple...
Magic Weisner, who burst onto the national stage after finishing just three-quarters of a length behind War Emblem in the Preakness Stakes (gr. I) is back at the track and could return to training within the next three weeks after contracting the West Nile virus.

Magic Weisner, the Preakness runner-up recovering from West Nile virus, was to have been released Thursday, Sept. 12, from the New Bolton Center in Pennsylvania. But veterinarians at New Bolton decided to keep the 3-year-old gelding a couple of more days, according to Dr. Bob Vallance, the horse's Maryland veterinarian.
Magic Weisner, the popular gelding who finished second at long odds in the Preakness, was diagnosed Monday with West Nile Virus, said Dr. Bob Vallance, a Maryland veterinarian.
Magic Weisner, the Preakness and Haskell Invititational runner-up, continues to show improvement from treatments he is receiving at the University of Pennsylvania's New Bolton Center. The 3-year-old is being treated with anti-inflammatory medications for the signs of encephalitis.
There seems to be little doubt that musculoskeletal injury--including injury to bones, joints, tendons, and ligaments--is a major problem for Thoroughbred racehorses. This impression has been borne out by studies of "wastage" in the racing industry, where wastage describes the losses that occur during the training and racing of a horse. In some studies...
The scientific community wrapped up a two-day workshop at the University of Kentucky's Gluck Equine Research Center Aug. 28 with a thorough review of research into mare reproductive loss syndrome, and some ideas on how to proceed in 2003.
Many Marion County, Fla., horse farm owners took the advice of their veterinarians seriously and vaccinated their horses against the vector-borne West Nile virus last autumn. It has resulted in a decrease in the number of cases in 2002.
Officials with the Jefferson County, Ky. Health Department said that at least one mosquito infected with West Nile Virus has been found at Churchill Downs.
The Kentucky Department of Agriculture announced late on Wednesday, Aug. 21, that six more horses had been confirmed positive for West Nile Virus (WNV) in the state. None had been vaccinated. Five of the horses are alive and one was euthanized on Aug. 19. This brings the total number of confirmed horses in the state to 25.

Surgery on a fractured shin in Proud Citizen's left front leg has been delayed. Dr. Stephen Selway postponed the operation, which was scheduled for July 1, because of several tiny fractures located near the main injury.
While visibly obvious, fatigue is hard to quantify. Electromyography (EMG) measures conduction along nerves in a particular muscle group--as muscle fibers fatigue, EMG signals shift from high to low. Taking EMG readings during galloping is unreliable, however, because signals are susceptible to inaccuracies from lead changes. Kinematics is another eval...

Partial paralysis of the larynx prevents maximal opening of the equine trachea. Affected horses can move air, but breathing noises occur, especially during exercise. The most common form of laryngeal paralysis is recurrent laryngeal neuropathy (RLN), which involves degeneration of the recurrent laryngeal nerve. The cause of RLN is unknown, but it seems...
Grayson-Jockey Club Research Foundation is funding a new project with the Kentucky Association of Equine Practitioners to seek critical information on Mare Reproductive Loss Syndrome (MRLS).
A research project begins well before the experiment starts. That was the case of the recently completed collaborative effort at the University of Kentucky that associated the Eastern tent caterpillar and its frass (excrement) and Mare Reproductive Loss Syndrome (MRLS). Work on that project began last fall, even before funding was finalized.
Reports from Central Kentucky and Ohio note that many farms are seeing no cases of early fetal loss, late-term abortions, or term births of compromised foals.
According to Dr. Richard Holder, a practitioner with the Lexington, Ky., firm of Hagyard-Davidson-McGee who specializes in mare reproduction and fetal sexing, early fetal loss is occurring this year as it did last year, just at a much lower rate.
Thoroughbred foals with symptoms similar to those associated with last year's Mare Reproductive Loss Syndrome are being brought to veterinary clinics in Central Kentucky, officials said Monday.
