At Horseman’s Day at the 50th annual American Association of Equine Practitioners (AAEP) Convention in Denver, Colo., Dec. 4-8, 2004, Sally Vivrette, DVM, PhD, Dipl. ACVIM, of Triangle Equine Veterinary Services in Cary, N.C., discussed strategies for keeping the performance horse healthy and fit.

“Maintaining a performance or pleasure horse represents a substantial investment of time and

“I used to think I knew how to evaluate a horse’s movement for lameness, until I started to look more carefully. Two different highly experienced practitioners can evaluate a lame horse, and come up with different [lame] legs,” said Kevin Keegan, DVM, MS, Dipl. ACVS, associate professor of veterinary medicine and surgery at the University of Missouri, in his presentation on lameness

Hudson found that embryo recovery can be enhanced by slight modifications of the standard embryo flush technique, and embryo transfer success can be improved by verifying that the embryo was not retained in the tip of the sheath with which the veterinarian performs the embryo transfer.

The hock, or tarsus, is a complex collection of joints in the horse. Identifying lameness in one or more of those joints, and treating the problem, can be challenging. However, Alberto Serena, DMV, MRCVS, of Auburn University, and colleagues have found that injecting medication into one joint can treat an adjacent joint as well.

Swor and her co-authors from Texas A&M University (TAMU) found out that deep digital flexor tendonitis (DDFT) is more common than previously thought, and it is found more often in the hind limb than the forelimb. Additionally, horses with hind limb DDFT are more likely to make a full recovery than horses with forelimb DDFT.

Christy Malazdrewich, DVM, MVSc, PhD, Dipl. ACVIM, assistant clinical professor at the University of Minnesota, discussed metabolic problems at Horseman’s Day at the 50th annual American Association of Equine Practitioners (AAEP) Convention in Denver, Colo., Dec. 4-8, 2004. She gave clear-cut descriptions of two baffling conditions–Cushing’s disease and metabolic syndrome. She opened with this

“We had heard several anecdotal reports of intra-articular administration of liquid silicone being used as a lubricant in equine joints (to treat osteoarthritis),” began Daniel Burba, DVM, Dipl. ACVS, professor of equine surgery at Louisiana State University, at the 50th annual American Association of Equine Practitioners (AAEP) Convention in Denver, Colo., Dec. 4-8, 2004. “It sounded kind of

Dyson and her colleagues discovered in a recent study that there were no significant differences in the angles of the distal phalanx (P3, or the coffin bone) between horses of mixed breeds, with and without DDFT injury. However, they found that when Thoroughbreds were considered separately from the other breeds, horses with DDFT lesions were more likely to have a more acute P3 angle.

Ken Bedell, DVM, of Cornell University, addressed one of the newer maladies that has shown up in the horse world–equine motor neuron disease–at Horseman’s Day at the 50th annual American Association of Equine Practitioners (AAEP) Convention in Denver, Colo., Dec. 4-8, 2004. He characterized the affliction as any disease that targets the nerves that coordinate the muscle structure, such as

While a large part of microscopic semen evaluation centers around motility (directional sperm movement) and morphology (sperm structure), some reproductive specialists think there’s more to the story. In an attempt to better understand stallion fertility, Steven P. Brinsko, DVM, MS, PhD, Dipl. ACT, associate professor of theriogenology at Texas A&M University, presented the results of

Performance horse veterinarians treat everything from the cutting horse to the dressage mount, but when it comes to issues pertinent to their practice, they are much alike. The problems of online and traveling pharmacies, clients’ administering medications, drug testing at shows, and compounding were discussed at the performance forum at the 2004 convention of the American Association of

Following the release of human clinical trial data demonstrating the link between pain-relieving medications known as COX-2 inhibitors and an increased risk of heart attack and stroke, the U.S. Food and Drug Administration recently issued a public health advisory recommending limited use of the drugs. The advisory, which also covers various non-steroidal anti-inflammatory drugs (NSAIDs)

Managing a mare’s estrous cycle is an integral part of breeding management, and human chorionic gonadotropin (hCG) is one hormone option for doing just that. Patrick McCue, DVM, PhD, Dipl. ACT, associate professor of equine science at Colorado State University, discussed the use of hCG to manage ovulation.

“Most of us have used hCG throughout our practice lifetimes,” he began. “It’s used to

The American Association of Equine Practitioners (AAEP) has added the welfare of unwanted horses in the United States to its priority list for the foreseeable future, according to AAEP leaders during the annual convention Dec. 5-8, 2004, in Denver, Colo.

While the AAEP’s stand against the national bill that bans slaughter of horses has been seen as a negative by many horse owners,

Septicemia is loosely defined as bacteria or bacterial components in the bloodstream. In foals, septicemia is the most common cause of death in the first week of life, noted Simon Peek, BVSc, MRCVS, PhD, Dipl. ACVIM, clinical associate professor of large animal internal medicine, theriogenology, and infectious diseases at the University of Wisconsin’s School of Veterinary Medicine, at the 50th
