Endoscopic exams the upper respiratory tract (URT) are often standard procedure when veterinarians evaluate Thoroughbred yearlings possibly destined for the racetrack. These exams, which evaluate URT function, can satisfy sale conditions and assess a horse's suitability for racing.
Tuesday, May 07, 2013Covering broodmares during the first month postpartum, often on the first postpartum estrus (termed "foal heat"), is routine practice at many dedicated breeding operations to ensure mares foal at roughly the same time each year. A mare that fails to conceive shortly after foaling continues to have subsequently later foaling dates, eventually mis...
Monday, April 01, 2013A team of researchers at Michigan State University's (MSU) McPhail Equine Performance Center offers hope to horse owners facing underrun heel and flat-footed woes with a 16-month study examining the short-term and long-term effects of a specific barefoot trimming technique on hoof conformation.
Thursday, January 03, 2013A team of researchers from the University of California, Davis (UC Davis), recently tested if idiopathic headshaking in horses could be similar to a condition in humans--trigeminal nerve pain caused by the reactivation of a latent virus.
Friday, November 30, 2012Breeding racing mares as early in the season as possible offers a financial incentive to breeders. Doing so means foals born early in the season, and the physical maturity of larger, early foals is in often in greater demand at yearling sales and in 2-year-old races than their later-born counterparts. Early in the breeding season, however, mares are ...
Saturday, October 13, 2012Post-and-board, vinyl constructed plank, braided tape, coated high-tensile wire, pipe: Many effective equine fencing options are available. However, there are no hard-and-fast rules as to which is the best choice, explained Bob Coleman, PhD, Equine Extension professor in the University of Kentucky's Department of Animal Sciences.
Saturday, September 22, 2012Clenbuterol, a beta-2-adrenoceptor agonist and the only FDA-approved medication for horses with reversible bronchospasm, is commonly used to treat horses with inflammatory airway disease (IAD) and recurrent airway obstruction (RAO, commonly known as heaves). Although it is often regularly administered to racehorses throughout the racing season, the long-t...
Wednesday, September 05, 2012You’ve seen it plenty of times: bare pasture grazed down to the nub. Who wouldn’t rather look out of the stable to see happy horses grazing on healthy pastures? One solution lies in rotational grazing, a simple management technique that subdivides pasture areas, which allows forage an opportunity to regrow after it's been grazed. By fencin...
Friday, August 03, 2012Breeders who utilize live cover can breathe a sigh of relief: While live cover breeding facilities sometimes face pathogenic bacteria outbreaks, results from a study led by University of Kentucky PhD student Katheryn Cerny, MS, demonstrated bacteria on stallions' external genitalia does not affect stallion or mare fertility.
Saturday, June 16, 2012Equine Sarcoids (ES), a common form of semi-malignant skin tumor, has long been recognized as having a genetic component, but how it's passed to offspring wasn't fully understood. Recently, a team of researchers conducting a whole-genome scan successfully located chromosomal regions associated with ES, bringing us one step closer to understanding ...
Tuesday, May 22, 2012While vaccination to control equine influenza (EI) in endemic areas is common practice, little is known about the use of early vaccination to eradicate the disease during an outbreak. Researchers recently examined the effect of early vaccination during an outbreak, using the 2007 EI outbreak in Australia, which had previously been free of EI, as a model.
Saturday, May 19, 2012Researchers at the Federal University of Pelotas, Brazil, recently completed a study identifying circulating cell-free fetal DNA (ccffDNA) to determine fetal gender in pregnant mares. While ccffDNA has already been explored in humans, this is the first study to successfully demonstrate its presence ccffDNA--and thus aid in sex determination--in horses.
Monday, March 05, 2012Prior to August 2007, there had been no reported cases of equine influenza in Australia; the 2007 equine influenza outbreak that ravaged New South Wales (NSW) resulted in a four-month epidemic, infecting approximately 70,000 horses before eradication was achieved.
Monday, February 20, 2012Cases of equine proliferative enteropathy (EPE), an intestinal disease that principally affects weanlings between four and seven months, have been on the rise in recent years. As Nicola Pusterla, DVM, PhD, Dipl. ACVIM, of the University of California, Davis, explained, EPE, caused by the bacterium Lawsonia intracellularis, is an emerging disease; it remai...
Monday, February 20, 2012Every horse owner is familiar with the ubiquitous flexion test, which veterinarians regularly employ to exacerbate baseline lameness and reveal unknown internal issues in horses. No standard duration, however, dictates how long veterinarians should hold the limb in the flexed position. Researchers recently tested the results of comparative full hind limb ...
Sunday, November 13, 2011Owners who keep their horses at boarding facilities or travel to events are likely familiar with their horses' risk of exposure to the respiratory disease strangles. This highly contagious disease is spread by horses shedding the Streptococcus equi bacterium while ill and for up to six weeks after clinical signs dissipate. Some horse owners choose to ...
