Veterinarians and researchers trying to pinpoint the cause of mare reproductive loss syndrome (MRLS) have joined together to create an MRLS “think tank,” the progress and goals of which were discussed April 1 at a joint meeting of the Kentucky Thoroughbred Farm Managers’ Club and the Kentucky Association of Equine Practitioners (KAEP) in Lexington.

An outbreak of African horse sickness detected last week in South Africa has killed 300 horses, according to a Pro-Med report. African horse sickness is a lethal virus spread by the Culicoides bolitinos midge, a species of small fly. Although African horse sickness is endemic to all parts of Africa, except the Western Cape, rain in the region has increased the midge population.

Keeneland, which opens for its spring meet April 4, is requiring all horses that enter the grounds to have a health certificate written within 72 hours of arrival.

River Downs in Ohio implemented a similar policy in the wake of the detection of equineherpes virus at Turfway Park in mid-March. The virus was contained through quarantine procedures, and horses in the affected barn are

Advanced reproductive technologies that can be used in horses are expanding every year. Geography is no longer a limiting factor in choosing a mate for your mare, as fresh cooled semen can be shipped across North America with ease. Frozen semen also means stallions from other continents can be used.

Amber is a 30-year-old Arabian mare which was slowly starving to death because her owners had run out of money to care for her. Because of her age and lack of potential and worth, Amber’s owners allowed her to be pushed out of food and veterinary care in their herd of 35 horses.

Whether it is the increased stress of daily life or the baby-boomer generation wanting to experience the roots of their pioneer forefathers, more and more people are setting out to see the country from horseback. As a result, equestrian campgrounds have multiplied throughout the country and the design of horse trailers has changed drastically to cater to the comfort of weekend or week-long

University of Florida (UF) research has shown that any exercise above a walk could force acidic gastric juices up into sensitive areas of the equine stomach, which could be why ulcers develop or worsen in horses in training (affecting more than 80% of performance horses in some studies).

Alfred Merritt, DVM, MS; and Mireia Lorenzo-Figueras, DVM, have found that gastric tension changes

The long-awaited reference Diagnosis and Management of Lameness in the Horse was recently released by Elsevier Science. The book was co-authored by Mike W. Ross, DVM, Dipl. ACVS, of the University of Pennsylvania’s school of veterinary medicine; and Sue J. Dyson, FRCVS, of the Center for Equine Studies at the Animal Health Trust in the United Kingdom. Ross and Dyson offer comprehensive

A question has been raised whether the increased number of West Nile virus (WNV) cases in Kentucky in late summer and fall 2002 contributed to a rise in fall abortions. A retrospective study by the University of Kentucky’s Livestock Disease and Diagnostic Center (LDDC), from July of 2002 through early 2003, looked at 400 equine abortions for evidence of WNV. Their findings were “surprising,”

A new Horse/Human Age Relationship Chart was recently released that seeks to better explain the relationship between the stages of life for humans and horses. This information reveals that, beginning at birth, horses age 6.5 years for each human year until puberty. Once a horse reaches age four, that rate slows to 2.5 years for each human year.

The Age Relationship Chart, created by

While Ohio veterinarians are busy fighting what seems to be an especially aggressive strain of equine herpesvirus type 1 (EHV-1), two horses were euthanized due to illness from the virus at Penn National Race Course in Grantville, Penn., in an outbreak that appears to be a more typical, sporadic episode. Additionally, at least two Iowa horses have been euthanized after battling what officials

Ohio and Pennsylvania have confirmed or reported cases of the neurologic form of equine herpesvirus type 1 (EHV-1, see Pennsylvania information on page 15). But the worst problems reported thus far have occurred in Ohio, where 12 horses died in an outbreak at the University of Findlay (see article #4127 at www.TheHorse.com) and three other Ohio horses die

By the time this magazine is in your hands, the Thoroughbred Retirement Foundation (TRF) will have released a report they commissioned to answer some of the questions raised in the industry about horse slaughter. The TRF is, of course, strictly a Thoroughbred rescue group. However, the issue of slaughter is one that touches every horse owner, so the information they provide is important to

What is the best feeding practice for horses before competition exercise or a hard training session? There is no real consensus on this issue and, similar to the field of human performance nutrition, there are many opinions on what is best. Some trainers will withhold all feed, some will decrease the amount of hay fed, and others will increase the amount of grain or other high-energy feed
