Consider Trotting Speed when Diagnosing Subtle Lameness

Most horse owners are familiar with a typical lameness exam: The veterinarian observes the horse trotting briskly in a straight line, watching for signs of uneven movement. But if the patient is harboring a mild lameness, that brisk trot could be masking clinical signs, according to British researchers, whose recent study results indicate that evaluating ...

Researchers Review Equine Sarcoidosis Cases

While still rare, equine sarcoidosis—not to be confused with sarcoid tumors, an unrelated skin condition—can appear in even the healthiest of horses. But don’t be too quick to treat sarcoidosis-associated hair loss, scaly and flaking skin, and crusting with creams, ointments, and lotions. According to Dutch researchers, it’s better...

Researchers Developing Equine Welfare Assessment Protocol

Do you know how to recognize equine welfare issues? While some signs of poor welfare are obvious, others are more subtle and possibly evident right in your own stable. According to Swedish researchers, there's a great need for research-based welfare assessments that take the guesswork out of judging equine well-being. And they've been busy develop...

Hoof Angles' Impact on Lameness Examined

Get out your protractors: New research shows that the various angles of the outer and inner hoof are directly linked to various kinds of lameness, and knowing the angles could help determine which kind of lameness a horse has or is likely to get.

'Limited Resource Test' to Measure Equine Social Hierarchies

As scientists discover more about the way a horse's social life affects his behavior and, possibly, training, researchers find themselves in need of a reliable, efficient way to measure social hierarchy. Danish behavior scientists appear to have found the solution through a "limited resource test."

Music Genre's Effect on Horse Behavior Evaluated

Ever thought of "jazzing" up your stables? Or getting your horses to "rock 'n' roll" in the stall? Better reconsider your music choices. According to British researchers, classical and country sounds are probably best for equine welfare.

Study Evaluates Cribbers' Sleeping Habits

Is worrying about your horse's cribbing habit keeping you up at night? It turns out that cribbing might keep your horse up at night, too. New research has revealed that the stereotypy could be related to a lack of certain kinds of sleep. Specifically, British researchers say, horses that crib spend less time in "standing sleep" mode than hor...

Advances and Challenges in Equitation Science Technology

Twenty-first century technology brings us into the once-science fiction world described by fantasy writers in the 1950s. We've got retina screens, hybrid vehicles, and a million different apps (not short for "Appaloosas," in this case). We can video chat with people on the other side of the planet in real time, and we can carry 50,000 photog...

Researcher: Work Objectively to Understand Equine Behavior

Think we're getting close to finally figuring horses out completely? Well, we're not. But the good news is that by working entirely objectively, equitation scientists are beginning to enter into a new dimension of understanding equine behavior. And that, according to a leading equitation scientist, will lead us into a "Golden Age" of hor...

Heart Rate Variability to Detect Equine Transport Stress

A fear of flying can lead to such extreme stress that many people find themselves unable to board an airplane. While horses aren't likely to show a true "fear of flying," they are undoubtedly stressed by air travel, according to a recently completed study of in-flight horses.

It also doesn't make them more or less severe, and it doesn't change the sites on the joint where they show up. In...

Genomic Research for Equine Performance Indicators

There's been a lot of excitement about equine genomic research over the past couple years, but horse buyers and breeders are still waiting for practical performance applications. The good news is that a team of French researchers might be hot on the trail to genomic evaluation of performance--even if that trail seems slow and winding--one researcher s...

Heart Rate's Effect on Equine Performance

A new show ring and a new environment can equate to stress--and even poor performance--for your horse. Because according to Danish equitation scientists, the faster a horse's heart rate in a new environment, the more likely he is to perform poorly.

Can Horses 'Watch and Learn'?

Watch and learn. It sure seems that horses can do it. One of them figures out how to open the gate to get to your not-so-well-hidden stock of carrots, and then before you know it, they're all getting orange in the muzzle. So can they really learn from each other? Maybe, according to a group of Danish equestrian scientists, but there's nothing cert...

Association Between Racehorse Purchase Price and Earnings

Thoroughbred racehorses have to run a pretty fast race to keep up with the money spent to get them to the track, according to a new study by Australian researchers. But it turns out that, at least up to a certain point, buyers are getting the value they're paying for--although it's still a great risk.

Behavioral Differences Between Colts and Fillies Examined

Many riders have a distinct preference when it comes to working with mares--they either love the girls or would rather avoid them. In some cases this choice is related to hormonal behavioral changes in mares during their heat cycles. But perhaps these behavioral differences are not just related to reproduction hormones. What if there was a fundamental dif...

Cooled Shipped Semen Quality Impacted by Collection Centers

When it comes to the quality of cooled shipped semen for artificial insemination (AI), all semen collection centers are not equal.

Researchers: Selenium's Value is in the Sperm, Not the Blood

The trace element selenium appears to reinforce sperm quality and thus maintain a stallion's fertility. When selenium is lacking, motility drops, sperm membranes break down, and the sperm's acrosome (which covers the head) can deform. But according to a new study by German scientists, feeding your stallion more selenium won’t necessarily imp...

Saddle Tree Types and Pressure Distribution

Modern saddles provide new options for tree type, with the goal of sparing a horse pain from localized saddle pressure. But new Swiss research suggests that, at least when a horse trots, tree type makes little difference in pressure distribution along the horse's back.

Racehorse Training Injuries Vary by Stable in New Study

Which kind of injury is most common to a racehorse? That all depends on who trains it and at which track, according to a group of British researchers.
