Genetically Speaking

Ireland is not a big country. It covers only 32,599 square miles, making it about the same size as Indiana. But Ireland plays a large and important role in the Thoroughbred industry. Some of the best runners in the world are raised on its limestone-enriched pastures. Two Irish-bred standouts-High Chaparral and Domedriver-won races at the 2002 Breeders'...

Genetic Compatibility

AAEP 2002 Racehorse Medication Table Topic

Horse racing has far more stringent medication regulations than most other equine disciplines, and this was reflected in the Racehorse Medications Table Topic discussion at the American Association of Equine Practitioners (AAEP) convention on Friday, Dec. 6. The majority of the discussion revolved around the legality of using various medications and their...

Juvenile Bowed Tendons and Racing Prognosis

“Juvenile bowed tendons, or ‘baby bows,’ are not uncommon in yearlings and weanlings,” said Johanna Reimer, VMD, Dipl. ACVIM, Dipl. ACVC (cardiology), of the Rood and Riddle Equine Hospital in Lexington, Ky., at the 2002 American Association of Equine Practitioners convention. In her presentation “Enlarged Superficial Digital Flexor Tendons in Immature Th...

Feed for Speed

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, 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.

Racing Toward Injury

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...

Radiographs and Selecting Racehorses

Veterinarians should select racehorses at auction, not "radiographically clean horses," Thoroughbred farm Three Chimneys' resident veterinarian Jim Morehead, DVM, told Australia's leading equine veterinarians at a yearling radiographic seminar Aug. 18 at Sydney University.

Preliminary Results Find Caterpillars Cause Late-Term Abortions

The University of Kentucky College of Agriculture has released preliminary results from a collaborative project involving the UK Livestock Disease Diagnostic Center, the UK Department of Veterinary Science, and the Hagyard Davidson McGee Equine Hospital. This project investigated the potential of Eastern tent caterpillars (ETC) to cause fetal loss when administered to mares in the late stages of pregnancy.

TRPB Part of Horse ID Seminar

One of the identification agencies that will be presenting information at the National Equine Identification Symposium in Chicago, Ill., July 28-Aug. 1, is the Thoroughbred Racing Protective Bureau (TRPB). The TRPB is a national investigative agency formed in 1946. One of its functions is the lip-tattooing of Thoroughbreds for the purpose of racetrack ide...

Fatigue in Racehorses

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...

Yearling Colt in Kentucky Dies Of West Nile Virus

A Thoroughbred yearling from the Lexington area has died of West Nile Virus. It is the first time this year West Nile has been identified in a horse in Kentucky, according to the state Department of Agriculture's office of the state veterinarian.

Laryngeal Paralysis

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...
