UPDATE: Hold Order on Barn 16 at Bowie has been lifted

BALTIMORE, 09-24-13---Blood samples on the Bowie Training Center-based horse that was humanely euthanized by the Maryland Department of Agriculture Saturday morning were negative for equine herpesvirus (EHV-1).

The Hold Order on Barn 16 at Bowie has been lifted, meaning the 27 horses stabled in the barn will be allowed to train beginning Wednesday morning, Sept. 25.

Efficacy of cyclo-oxygenase inhibition by two commercially available firocoxib products in horses

Article first published online: 16 JUL 2013 Equine Veterinary Journal

Results

In the control group, there was no significant change in LPS-induced PGE₂ over time. In contrast, immediately prior to and 1 h after treatment on Day 7, the mean LPS-induced PGE₂ concentration decreased significantly compared to Day 0 values in all treated horses. There was no difference in PGE₂ or plasma firocoxib concentrations between firocoxib treatment groups.

Conclusion

In this model, the canine chewable preparation of firocoxib was as effective as the equine paste formulation at reducing LPS-induced PGE₂ synthesis.

Potential relevance

The canine chewable preparation of firocoxib may be a suitable alternative to the paste formulation in horses for situations where extra-label drug use can be legally justified.

Is Your Horse Too Fat? There's an App for That

Is Your Horse Too Fat? There's an App for That

By: University of Kentucky College of Agriculture        Aug 22, 2013

A recent collaborative project between equine researchers from the University of Minnesota and the University of Kentucky has resulted in an app that helps horse owners better determine their horse’s body weight.

Knowing the weight of a horse relative to the ideal weight of his breed can help owners better determine their horse's nutritional needs and medication dosage.

Born from collaborations between UK and University of Minnesota over the past several years on equine metabolic studies, the two sets of university researchers often discussed how the industry needed a way to more easily measure a horse’s body weight.

“We wanted to come up with a better way to determine a horse’s body weight and provide something similar to the BMI (body mass index) measurement currently used in humans,” said Bob Coleman, PhD, PAS, associate professor in UK’s Department of Animal and Food Sciences and extension horse specialist. “We also wanted a scoring system that wasn’t going to be as impacted by the adiposity (fat deposits) of a horse as the current method of using girth measurement to determine a horse’s body weight.”

Asked if researchers were successful in developing that something, Coleman’s short answer was yes.

“The big thing is that it gets people talking about where they are with their horse instead of guessing. If they want to use technology to do that, they can,” Coleman said. “We found that horse owners were excited to give us the data and more excited when they found out how it could help them manage their horses.”

Morphometric measurements collected on 629 horses in Minnesota, including height at the third thoracic vertebra (A), neck circumference located half way between the poll and withers (B), girth circumference at the base of the mane hairs (C), and body length from the point of shoulder to a line that was perpendicular to the point of the buttock (D).

Coleman helped collect data on 629 horses at the Minnesota State 4-H Horse Show and Western Saddle Club Association Championship Show. Owners volunteered their horses for measurement and for those figures to be used as part of the data.

The app, called the Healthy Horse App, is marketed by the University of Minnesota and currently available only on the Apple app store, with plans for compatibility with android devices soon. It currently costs $1.99, and according to Coleman, proceeds will be used to help improve the app's functionality in the future.

The app currently works for adult Arabian horses, Miniature horses, ponies, saddle horses (defined as Morgan, Mustang, Paso Fino, Saddlebreds, Tennessee Walking Horses), and stock horses (Appaloosas, Appendix, Paint Horses, Quarter Horses, and Thoroughbreds).

When using the app, Coleman said owners provide measurements, in inches, for their horse’s girth circumference, neck circumference, body length (with diagrams showing how to measure from the shoulder to the hindquarters), and height at the top point of the withers. Those measurements are then calculated through formulas developed by university researchers to provide the horse’s weight. A comparison ideal weight of that breed is also given, which lets owners see if their horse is over or under the ideal weight for that breed.

The project’s team included Coleman; Molly McCue, DVM, Dipl. ACVIM, PhD, associate professor at the University of Minnesota’s Veterinary Diagnostic Laboratory; Krishona Martinson, PhD, associate professor at the University of Minnesota Department of Animal Science; Nicol Schultz, DVM, graduate student at the University of Minnesota Department of Animal Science; Aaron Rendahl, of the University of Minnesota School of Statistics; and Krishna Natarajan, graduate student in Computer Science at the University of Minnesota.

Eastern Equine Encephalitis Confirmed in Maryland Horse

Eastern Equine Encephalitis Confirmed in Maryland Horse;
Marylanders Urged to Take Precautions; Horse Owners Encouraged to Vaccinate

BALTIMORE (August 16, 2013) – A case of Eastern equine encephalitis (EEE) has been confirmed in a horse in Worcester County.  The horse tested positive for EEE which, like West Nile virus, is spread by mosquitoes. Officials remind Marylanders to take precautions to protect themselves and their families from mosquito bites to prevent mosquito-borne diseases.

EEE is spread by the bite of an infected mosquito and can cause a swelling of the brain (encephalitis). The disease is rare in humans, but can occur when an infected mosquito bites a person. EEE disease occurs primarily in areas close to swamps and marshes with high mosquito populations. The last confirmed human case in Maryland was in 1989, and prior to that there were two cases in 1982. The last confirmed case in a horse in Maryland was in 2009 in Wicomico County.

Although EEE occurs in humans less frequently than West Nile virus (WNV), it can be more serious. Only a subset of people infected with either virus develop neurological illness, however of those who develop neurological illness, approximately one-third of all EEE-infected persons may die compared to fewer than 10 percent who die following WNV neurological illness. EEE survivors can have long-term damage to the nervous system.

Typical symptoms of EEE in humans include fever, headache, mental confusion, nausea, vomiting, muscle aches, joint pain, and sometimes seizures and coma. Individuals reporting these symptoms should be referred to their health care provider. Symptoms usually occur four to 10 days after exposure to a mosquito carrying the virus. There is neither a specific treatment nor a vaccine available for use in humans infected with EEE virus.

In horses, EEE is a serious disease that can be fatal; however, well vaccinated horses are generally safe from the disease. The Maryland Department of Agriculture (MDA) encourages all horse owners to consult with their veterinarian to discuss the best vaccination program for their horse and its circumstances.  The horse in Worcester County had not been vaccinated. Infected horses show a range of clinical signs that often progress over two to three days, including depression, altered mental status, circling, problems with balance, weakness, aimless wandering, impaired vision, walking (gait) abnormalities, head pressing, paralysis, convulsions and death. Horses that survive serious disease often have permanent nervous system deficits.

MDA, working with Worcester County officials, has mapped out a 6,000 acre area in the Whaleyville area where air spraying for mosquitoes will be conducted tonight, beginning at 5 p.m.  MDA generally checks mosquito populations in the area every week and conducts ground spraying according to its findings. As a result of the EEE discovery, MDA will increase ground spraying activities to approximately every 5 to 7 days over the next two weeks. Spraying will take place between dusk and dawn.

Measures people can take to protect themselves from diseases spread by mosquitoes include:
•       Avoid areas of high mosquito activity
•       Avoid unnecessary outdoor activities at dawn and dusk when mosquitoes are most active
•       Wear long pants, long-sleeved shirts and hats to reduce mosquito exposure
•       Use an EPA-registered insect repellent according to package directions
