Laurel Park Horse Tests Positive for Equine Herpesvirus

Hey Ralphy, a filly trained by Rodney Jenkins at Laurel Park, was infected by equine herpesvirus (EHV-1), according to the Maryland Department of Agriculture. The 3-year-old was euthanized Jan 26 with a suspected pelvic injury. A Hold Order has been placed on Barn 9, where the filly was stabled, at the central Maryland track.

Breeding Specialists

The equine breeding industry has evolved dramatically with the introduction of artificial insemination programs and advanced assisted reproductive techniques. While live cover breeding pro-grams are still a mainstay for specific breeds, many breed associations now accept foals conceived through the use of cooled and frozen semen, embryo transfer, and adva...

ReRun Using Stickers to Protect Thoroughbreds

ReRun Inc., the national Thoroughbred adoption group, has created stickers for use on a foal or horse's Jockey Club certificate to provide a contact for a subsequent owner who is unable or unwilling to provide a retirement for a Thoroughbred at the end of its racing or breeding career.

British Researchers Plan to Extract DNA From Three Racing Greats

Researchers from the Royal Veterinary College (RVC) in Hatfield and Cambridge University in England plan to extract DNA from the bones of three of history's greatest Thoroughbred racehorses -- Eclipse, Hermit, and St. Simon. Details of the proposed study were presented at the British Association Festival of Science held at Trinity College in Dublin, Ireland, in September.

RMTC Addresses Withdrawal Guidelines

The Board of Directors of the Racing Medication and Testing Consortium (RMTC) commissioned Dr. Rick Sams of Ohio State to develop an action plan, timeline, and research priorities to establish guidelines for withdrawal times for therapeutic medications commonly used by racetrack veterinarians.

South African Bleeders Study Begins

An international collaboration of researchers launched a study in July to examine the prevalence and severity of exercise-induced pulmonary hemorrhage (EIPH) in more than 800 South African Thoroughbreds. The group from the University of Pretoria, The Ohio State University (OSU), and the University of Kentucky (UK) also will examine the effect of altitu...

Bigger Thoroughbreds Sell Better

2005 EQUINE SCIENCE SOCIETY SYMPOSIUM, TUCSON, ARIZ., MAY 31-JUNE 3

"Pedigree, conformation, and the racing performance of siblings are the main selection criteria utilized by buyers to evaluate the athletic potential of Thoroughbred yearlings," said Joe Pagan, PhD, president of Kentucky Equine Research in Versailles, Ky. He also ...

Preventing Bucked Shins

Shin soreness, or bucked shins, in Thoroughbred racehorses is a partly preventable condition according to a recent Australian study. Horses with shin soreness display signs of pain on the front of the shins between the knee and fetlock, said David Evans, BVSc, PhD, associate professor of veterinary science at the University of Sydney and one of the resear...

Puberty in Thoroughbreds

Puberty is a transitional period for horses, from a time of reproductive immaturity to a time where sexual behavior is demonstrated and sperm is ready for release in the colt, and the filly starts to cycle. Unfortunately, very little information is available about puberty in horses, including at what age and what weight most horses reach this important li...

Study Shows Bigger Yearlings Bring Higher Prices

While pedigree, conformation, and the racing performance of siblings are the main selection criteria utilized by buyers to evaluate the athletic potential of Thoroughbred yearlings, there is also a positive correlation between size of a yearling and selling price at the Keeneland September yearling sales, according to Dr. Joe Pagan.

Mothers to Be

While the socialization process of transforming fillies and mares from racetrack careers into broodmares might be easier than it is for stallions, biologically it is significantly more complex for distaffers to begin their reproductive duties.

Conformation of Racehorses

"Forelimb conformation receives lots of attention because of perceived predisposition to injury (with various conformational problems)," began Liz Santschi, DVM, Dipl. ACVS, clinical associate professor at the University of Wisconsin-Madison, at the Western Veterinary Conference held Feb. 20-25 in Las Vegas, Nev.

Cold Air and Lung Health

Researchers at Oklahoma State University (OSU) recently completed a study on airway cooling and mucosal injury during cold weather exercise. Using the Thoroughbred racehorse as a model, scientists found that even cantering in sub-freezing temperatures can induce airway obstruction (bronchoconstriction, or airway contraction). The research appeared in the ...

CHRB Issues Policy on Florida Shippers

Responding to the presence of the bacterial infection strangles among racehorses in Florida, the California Horse Racing Board, in conjunction with the state's racetracks, has established a policy setting health requirements for horses being shipped from Florida to California.

Breeding Efficiency in Kentucky Thoroughbred Mares

Management and veterinary care are important factors that contribute to the overall pregnancy rate of the Thoroughbred mare, said Karin Bosh, a graduate research assistant in the University of Kentucky's Department of Veterinary Science. Bosh presented research supporting the link at the university's Gluck Equine Research Center on Feb. 8.
