Peripheral Cushing’s syndrome (PCS) is seen in middle-aged horses with obesity-associated laminitis. These horses tend to accumulate fat in the crest of the neck, over the rump, and in the sheath of male horses. Researchers are trying to understand this recently named syndrome. It was first proposed that classic Cushing’s disease–a disorder of the pituitary gland that leads to excessive

The introduction of antimicrobial drugs to veterinary medicine has made a dramatic improvement in the health of our horses, but it’s alarming when infections do not respond to these drugs. “It is not a new phenomenon, but there has been ever-growing concern about antimicrobial resistance,” said Josie Traub-Dargatz, DVM, MS, Dipl. ACVIM, of Colorado State University, in her presentation at the

As post-performance drug testing methods become more sensitive, racehorse and show horse owners, veterinarians, handlers, and trainers have become more aware that positive drug tests could be the result of inadvertent contamination of the horse with chemicals present in the environment. Cynthia Kollias-Baker, DVM, PhD, director of the Racing Laboratory at the University of Florida, recently

Internal parasites can be a very serious problem for horses. Even though most owners are aware that deworming is a necessary part of an overall good health program for their horses, the veterinarian is sometimes left out of that loop. Because deworming agents are available over-the-counter, many–if not most–horse owners deworm their own horses without their veterinarian’s advice or

The American Association of Equine Practitioners (AAEP) has recently revised and redesigned 21 client education brochures with the support of Bayer Animal Health and Purina Mills.

Some natural and man-made compounds in the environment can disrupt the delicate reproduction hormone balance in many species, possibly including horses. Her suggestion was that although this cause of reproductive dysfunction had not been studied in horses, it should be considered in cases of reproductive abnormalities with no apparent cause.

Since the beginning of the mare reproductive loss syndrome (MRLS) in 2001, there have been many theories as to the cause of the problems. Honing in on the extreme number of Eastern tent caterpillars (ETC) in 2001 and 2002, studies have shown that early fetal loss can be caused by feeding ETC to pregnant mares. It also has been shown that freezing the caterpillars does not destroy whatever

Morris Animal Foundation (MAF) has announced funding for eight new 2003 equine studies. Research topics include laminitis, endotoxemia, colic, genetics, immunology, and foal diseases. Nine continuing projects focus on similar issues as well as tying-up, equine infectious anemia, and neurological disease.
