The genetics behind the athletic performance of Thoroughbred racehorses has been a popular area of research in the past few years. A large-scale study was carried out recently in Japan, the results of which corroborate those of previous studies: Identifying specific "performance genes" on equine chromosome 18 could identify the ideal distance fo...
Horses have traditionally been considered obligate four-legged animals; however, the dogma is changing. Three-legged horses that walk easily with the assistance of a prosthetic limb are not as uncommon as they once were.
Perhaps your horse's performance is lacking, or maybe he sounds like a freight train as he labors through work. He could be suffering from left recurrent laryngeal neuropathy, commonly known as roaring. But how can you get a diagnosis quickly and easily?
Sometimes racehorses collapse on the track for reasons that are not immediately apparent; these exercise-related sudden death cases are uncommon and "poorly understood," according to an international team of researchers that recently completed a retrospective study on the subject. They noted that veterinarians are only able to determine the actu...
We've all heard about or witnessed horses that simply refuse to be restrained long enough for the veterinarian to administer a much-needed intravenous sedative. Authors of a recent study suggest that a sedative-containing gel might be just what the doctor ordered in these cases.
Monitoring lactate levels in samples of peritoneal fluid, the fluid surrounding and lubricating the abdominal organs, can help a veterinarian predict which colicky horses require surgery. John G.

Polymerase chain reaction (PCR) is a fast, accurate, quick, and easy testing method to diagnose pathogens associated with equine upper respiratory tract infections, and researchers on a recent study recommended that veterinarians pursue PCR in cases of infectious upper respiratory disease. Not only does it allow the veterinarian to pinpoint the causative ...
"Donkeys are becoming more common patients for equine veterinarians, and although it is tempting to treat a donkey like a horse, there are important differences regarding patient handling and drug dosages," cautioned Lori Bidwell, DVM, of Lexington Equine Surgery and Sports Medicine in Kentucky. Bidwell spoke on the key differences between anest...
After years of intensive research, a product called SucroMate has achieved the coveted status of FDA-approved for reproductive health in mares. This is no easy feat as only two veterinary drugs obtained FDA approval in 2010. SucroMate is licensed to induce ovulation in mares being bred with fresh, cooled, or frozen semen.
Veterinary researchers have taken a leap forward in explaining XY sex reversal, the most common equine sex chromosome abnormality. A team of scientists from the University of Kentucky's Gluck Equine Research Center and the College of Veterinary Science at Texas A&M University have been examining the Y chromosome to determine what prompts a genetic...
Researchers suspect tying-up in horses is a heritable condition; however, they have yet to determine the gene--or genes--responsible. But a team of Japanese researchers recently moved the investigation forward with a groundbreaking study of affected Thoroughbred racehorses' DNA.
Angular limb deformities (ALDs) of the carpus (knee) are a common problem in foals and yearlings, and researchers have narrowed the surgical treatment options down to the two that present the best results. Eric R. Carlson, DVM, an equine surgery resident at the University of Illinois' Veterinary Teaching Hospital, gave a presentation on these options ...

According to a news story originally posted by British magazine Horse and Hound, the deaths of 40 horses--which occurred between March and June--residing on five different farms in Queensland, Australia, remain under investigation. Australian veterinarians have told reporters that they suspect the culprit is a tropical plant of, or related to, the species...

Cutting-edge research conducted on microscopic tunnels in horses' intestinal walls has revealed that these channels play a key role in helping intestines heal after life-threatening colic episodes.
In the not-so-distant future, researchers believe they will be able to genetically modify stem cells to create a “vaccine,” so to speak, to treat a large number of musculoskeletal and other disorders in both humans and horses. An Italian research group has made recent strides in further understanding the potential of using stem cells derived f...
Imagine sustaining a fracture or undergoing orthopedic surgery and being prescribed a drug that helps control pain and inflammation. This medication is a non-steroidal anti-inflammatory drug (NSAID). But there is a catch: the drug that helps control your pain inhibits bone healing.
Neurologic signs observed in horses undergoing treatment with the commonly used antibiotic combination of trimethoprim (TMP) and sulfonamide have prompted researchers to warn veterinarians and owners about this potential side effect. They also recommend that veterinarians report potential adverse drug reactions (AEs, or adverse events).
Despite the fact that horses evolved on a forage-based diet that is high in fiber and low in calories, some horse owners and trainers just can't resist feeding a low-fiber, calorie-dense diet.
As of Oct. 8 more than 2,300 horses associated with the Kleberg County, Texas, piroplasmosis outbreak have been tested for the disease, and 409 have turned up positive--only one more since the previous report from the USDA to the World Organization for Animal Health on Aug. 25, 2010.
Appropriate preventive and therapeutic measures to avoid and/or treat gastric ulcers in endurance horses might improve performance.
Scientists have established the link between cribbing (also called windsucking) and colic, but a "causal" relationship between the two remains to be proven, say researchers from the University of California, Davis.
Magnetic resonance imaging (MRI) of the foot is a valuable tool in diagnosing equine lameness and can clearly identify fragments or chips originating from the distal border of the navicular bone ... but researchers say, "so what?"
Stem cell therapy for tendon injuries is used increasingly in clinical practice, yet a number of important hurdles persist that made one group of researchers look at using embryonic stem cells rather than bone marrow-derived stem cells in horses.
The regenerative medicine field has progressed faster than Secretariat's 1973 Belmont stakes win. And a Cornell University research team that uses horses' own bone marrow to successfully treat joint injuries is helping take stem cell therapy to the next level.
In study that could have been dubbed "Who's smarter than a veterinarian?" Michigan State University researchers concluded that when it comes to assessing chronic respiratory disease changes in horses, the answer is … owners.
Officials have confirmed the number of Potomac Horse fever (PHF) cases in northern New York has been higher than usual in recent weeks, encouraging owners to vaccinate but noting that a rise in cases is relatively common this time of year. An article printed in the Aug. 14 edition of the Watertown Daily Times reported there is an "outbreak"...
Compared to other species, cloning horses is still in its infancy. Cloning is becoming increasingly popular, yet the health of these artificially-produced foals has not been assessed in detail.
Surgeons from Texas A&M University's College of Veterinary Medicine have given a facelift to a standard procedure that removes part of a horse's penis secondary to damage or disease.
A pile of horse dung is no longer just a pile of horse dung--it is now the stage for the fatal ambush of nematode (roundworm) larvae by a predatory fungus, worthy of screen time on the "Mutual of Omaha's Wild Kingdom" nature show.
In an equine study using "proteomic" technology that systematically analyzed the proteins in skeletal muscle biopsies, a research team from The Netherlands identified a form of the protein creatine kinase that could be a marker for acute tying-up in horses.
In a letter to veterinarians dated April 28, Brett Whitehead, Director, Equine and Ag Retail Business, of Intervet Schering-Plough Animal Health, encouraged practitioners to return all PreveNile vaccine. The recall was initiated after an increased incidence in the number of adverse events following vaccination with currently marketed serials of PreveNile.
