11 October 2017 THE HORSE For additional news items, see The 2018 WEVA Congress will take place April 21-23 in Beijing, China. The event, which is being organized in concert with the China Horse Industry Association, is designed to fulfill WEVA's mission of advancing equid health and welfare around the world by pro- moting and offering quality continuing education for equine practitioners, specifically in countries with limited access to high-quality broad-based veterinary continuing education. On the two days preceding the main congress (April 19-20), WEVA will hold wet labs covering: ■ Prepuchase examinations; ■ Preparing for competition; ■ Diagnostic imaging; ■ Lameness examinations; ■ Farriery manage- ment of hoof diseases; and ■ Dentistry. More than 50 lecturers from Australia, Belgium, Chile, China, France, Germany, Hong Kong, India, Ireland, Italy, New Zealand, Switzerland, the Unit- ed Kingdom, and the United States are lined up to present at the Congress. Program co-chairs and WEVA board members Chris Riggs, BVSc, PhD, DEO, Dipl. ECVS, MRCVS, and Henry Tremaine, BVetMed, CertES (Soft Tissue), MPhil, Dipl. ECVS, EVDC, FHEA, MRCVS, are working to assemble an educational program covering many aspects of practical equine veterinary medicine, surgery, and theriogenology (reproduction). Speakers will present on such topics as wound care, hoof care, lameness (including nerve blocks, fracture repair, and cartilage resurfacing), diag- nostic imaging, infectious diseases, respiratory diseases, cardiology, ophthalmology, and den- tistry. Additionally, presenters will cover practical information targeting nonveterinarians; subjects include nutrition, drug testing, equine insurance, biosecurity, and national and international travel.

ACVIM, WEVA President Imagine being able to test show or racehorses for more than a hun- dred drugs at once, automatically, with results in a matter of minutes. No need to imagine it, however, because Hong Kong researchers are doing it. "The short run time enables a high throughput with minimal labor requirements and is especially useful in time-critical operations such as pre-race analysis," said Terence S.M. Wan, PhD, EurChem, CSci, CChem, FRSC, FAORC, FCSFS, head of The Hong Kong Jockey Club racing laboratory and chief racing chemist. Wan and co-authors described the technique in a recent Journal of Chromatography A. This new system uses online solid phase extraction (SPE); SPE is a popular sample preparation technique that essentially isolates dissolved target components (i.e., drugs) from the liquid they're dissolved in (in this case, urine). "Online" means the samples are run automatically through the "line" of analytical equipment without human intervention. The system Wan and colleagues developed runs the enzyme-treated urine samples through online SPE for preparation, then introduces each resulting extract sequentially into the liquid-chromatograph/ high-resolution mass spectrometer to check for the presence of 118 common doping substances. Unlike many current tests, which take one to two days to produce results, Wan's test takes only 16 minutes— including sample cleanup and machine resetting time. The new test is adaptable, even retrospectively, as new drugs are discovered. Wan said scientists can go back to recorded full-scan data later and search for possible evidence of new drugs without retesting the sample. Finally, he added, because it checks for so many drugs simulta- neously with minimal human labor involved, the direct costs would be lower. This test can be used in any laboratory worldwide that has ac- cess to appropriate instrumentation and reference materials, Wan said.

PLEASE NOTE: Travel VISA is required From the Olympic Green, to The Forbid- den City, to The Great Wall, Beijing has charming attractions for every traveler. For more information, please see the official Congress website at Although the breed has been gaining popularity in the dressage arena, the Friesian is no "traditional" sport horse. Neither Warmblood nor draft, researchers have confirmed that Friesians have their own particular set of physical challenges in training. That doesn't make them weaker or inferior to typical Warmblood dressage horses, however, the scientists say. "Friesian horses need to be managed in a different way," said Cathérine Delesalle, DVM, PhD, Dipl. ECEIM, of Ghent University, in Belgium, and a visiting professor at Utrecht University, in the Netherlands. Specifically, Delesalle revealed in the study that Friesians need special exercise regimens and warmup durations because they reach fatigue limits faster than Warmbloods do—something she said she's heard from dressage riders used to spending several hours warming up their Warmbloods. "(Friesians) need short, intensive preparation just before they enter competition," she said. As her team's research advances, she hopes they can contribute not only to the horses' performance and riders' satisfaction with the breed but also to a better-adjusted sports life for the Friesian. "Our main goal is support equine welfare," she said. "It is well-known that improper training and performing competition at a level for which the horse is not ready can lead to sports injuries, as well as poor welfare."
