Horse Pain and its Impact on Reproduction

A broodmare battling chronic laminitis, a stallion with recurrent uveitis, and a maiden mare with persistent tendinitis: While these horses and their conditions are each distinct, the animals do share the potential for exhibiting pain-related fertility problems. A University of Florida (UF) veterinarian described how equine pain might influence reproducti...

Oviduct Issues in Mares

When many breeders consider mare fertility issues, most don't consider that the oviduct—the slender channel through which eggs travel from ovary to uterus—could be causing problems. While oviduct-related fertility issues are rare in horses, breeders should be aware of what can go wrong with this important structure.

Prostaglandins for Controlling Mares' Estrous Cycles

Breeders always appreciate ways to help improve their mares' chances of becoming pregnant, and one way veterinarians can help is by administering prostaglandins. At the 2013 Society for Theriogenology Conference, held Aug. 7-10 in Louisville, Ky., Carlos R. F. Pinto, MedVet, PhD, Dipl. ACT, presented a lecture on using prostaglandin F2? (PGF) to contr...

Equine Placentitis Update

What's the most common cause of late-term abortion in horses and remains challenging for veterinarians to diagnose and treat, despite ongoing research? If you said placentitis, you're right. To bring attendees of the 2013 Society for Theriogenology Conference, held Aug. 7-10 in Louisville, Ky., up to speed on the latest research on the complex top...

Top Foal-Related Studies of 2012-'13

Even though they're small in stature, foals can have some big health problems. And researchers around the world are continually working to better understand these health problems and find more effective ways to treat them. At the 2013 Society for Theriogenology Conference, held Aug. 7-10 in Louisville, Ky., Chris Sanchez, DVM, PhD, Dipl. ACVIM, associ...

Botulism in Horses: An Update

Rising hay prices and the financial crunch caused by 2009's Great Recession drove many horse owners to seek less expensive forage sources, including large round bales, haylage, and silage. But according to Amy Johnson, DVM, Dipl. ACVIM, compromising on hay quality and feeding from half-ton bales led to a larger problem: an uptick in reported cases of ...

Commentary: Avoiding the Edge

Eric Mitchell, editorial director and editor-in-chief of The Blood-Horse, shares his thoughts on the recent Texas ruling about registration of cloned foals for the American Quarter Horse Association and how that might impact the Thoroughbred industry.

Zinc's Role in Young Horses' Immunity

Young horses require specific levels of amino acids, vitamins, and minerals for proper development, and researchers know that zinc, in particular, is vital for growing horses' enzyme and immune function. However, there's been little research done in horses evaluating the relationship between zinc and the equine immune system. So researchers from A...

Equine Immunodeficiencies Reviewed

A strong immune system is crucial to a horse's overall health status, as a weakened immune system can leave the animal at increased disease risk. And although they're uncommon in horses, immunodeficiencies can have serious consequences for affected animals.

Can Fatty Acid Supplementation Help IR Horses?

Equine insulin resistance—a condition in which cells fail to respond normally to the hormone insulin—requires careful dietary management to prevent laminitis and other complications from developing. So it's no surprise that both veterinarians and horse owners are on the lookout for new ways to help manage this disorder.

Equine Emerging Diseases Reviewed

Tracking emerging and re-emerging equine diseases helps the horse world attempt to stay a step ahead of economically devastating and deadly outbreaks. For that reason, equine veterinarians and industry members gathered on June 14, for Merck Animal Health’s "Equine Emerging and Re-emerging Disease Luncheon" at the 2013 American College of V...

Fetal Consciousness' Impact on Equine Neonatal Health

Somewhere between when the birthing process begins and when the long-legged foal takes his first wobbly steps, he transitions from an unconscious fetus to a conscious horse. And while owners might just be happy to see their new arrival waking up to the world, researchers now believe that the fetal consciousness transition could have a significant impact o...

Equine Postoperative Ileus Insights

When an owner sends a horse under the knife for colic surgery, he or she is first and foremost hoping the horse survives the operation. But just because he makes it through the procedure doesn't mean he's out of the woods: Many horses develop a dangerous complication called postoperative ileus—a lack of gut motility after surgery.

Osteochondrosis Field Evaluation Protocol Developed

It's common knowledge that osteochondrosis—a developmental orthopedic disease that results from a disruption in the growth of articular cartilage located in specific joints—can cause problems for young horses, but how common is it? How are different breeds affected? Where are the most common lesion sites? And, of course, what’s the m...

Equine Collapse Reviewed

There are few things more frightening for an owner than watching their horse collapse without warning or apparent cause. By the same token, unraveling the cause behind an equine collapse often presents veterinarians with a diagnostic challenge, and in many cases the root cause of a horse's collapse can't be determined.

Snakebite in Horses

With warm weather comes the increased risk of snakebite. The major venomous snakes in the United States are the pit vipers, including rattlesnakes, water moccasins, and copperheads. Pit vipers are named after the heat-detecting holes, or pits, on each side of the head that help the snake locate prey. Pit vipers can be differentiated from other snakes by t...

Turnout Time's Impact on Grass Consumption and Fecal pH

Many a horse or pony owner has restricted their overweight equid's turnout time in an effort to help him shed pounds. And while researchers know weight loss helps improve horses' overall health, until now they haven't known exactly what impact restricted grazing has on the equine gastrointestinal health or calorie intake. A group of North Caro...

Feed Delivery Methods' Effects on Glucose, Insulin Response

There are a number of ways to help prevent insulin resistance (IR) or associated conditions like laminitis in horses, but did you know that how you feed your horse could be one of them? According to recently published study results, feeding methods that slow horses’ feed consumption rate can also reduce their insulin and glucose responses directly a...

Study: Broodmares on Pasture Don't Always Need Grain

Horse owners are continually looking for ways to reduce feed costs without disturbing their horses' health, and a group of French equine nutritionists have some good news in this department: According to recent study results, lactating saddle horse mares on good quality pasture didn’t need to be fed grain to maintain their weight or their foals&...

Management's Impact on Osteochondral Lesion Development

Do you bed your young horses down in stalls in the winter? How smooth and flat are your pastures? When you’re trying to raise good bones and joints, these questions are worth considering. Because, according to French researchers, how you manage your young stock can have a direct effect on how osteochondral lesions evolve—for better or for worse.

Headshaking Supplement Efficacy Tested

Sure, many horse owners add feed supplements to their horses' diets to help maintain joints, hooves, and hair coats. But what about to stifle headshaking? Researchers at the University of Liverpool in England recently tested the efficacy of a feed supplement designed to alleviate this behavior in a trial involving 32 horses previously diagnosed with c...

Feed Choices Can Mean Cost Savings for Horse Owners

Few horse owners have remained unchallenged by the intractable recession. Rising fuel and feed costs have pushed horse ownership expenses skyward.
