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...
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...
Cervical vertebral malformation (CVM) is considered, by some, a diagnosis that leaves a horse with little hope of an athletic career. But according to recent study results, some carefully managed CVM horses could have a productive future ahead of them, after all.
Inflammatory conditions of the pastern will be appearing with increasing frequency during the summer season. But as a diagnosis, “pastern dermatitis” leaves much to be desired. When this alone is noted on a biopsy report, it leaves the clinician and client with little useful knowledge.
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...

But researchers have recently found that the same is true when the stress comes after the training session. Recent studies by French behavior scientists have revealed that when it comes to helping your horse retain what he learns during t...
Some veterinarians hypothesize that overactive immune responses in mares can cause early pregnancy loss, and new research results show that a reduction in a certain kind of immune system cell could be a red flag for diagnosing equine miscarriage.
Many horse owners have their hay-buying ritual down to a science. But from time to time, owners might find themselves rethinking their ritual, possibly due to drought, floods, or other factors that limit the forage supply in their area.
It's common knowledge that horses' individual personalities play a role in how they behave. Scientists have even developed various equine personality tests—most of which use objective criteria in a scoring system—to determine personality type. But researchers have recently developed a new subjective personality test designed to help us...
The Ontario Racing Commission (ORC) announced June 12 that there have been five confirmed reports of the neurologic equine herpesvirus-1 (EHV-1) in Thoroughbreds residing in Barn 1 at Woodbine Racetrack in Toronto, Ontario, Canada.
Many horse owners understand the important role nutritional building blocks, such as protein and minerals, play in young horses’ growth, but they might not consider the endocrine or metabolic consequences of their feed choices.

All horses'—from young to old, high-performance to sedentary, rescued to syndicated, and everywhere in between—gastrointestinal (GI) tracts function in the same manner. And owners of all types of horses should take the same steps to help keep their animals' GI systems functioning optimally.
Many people employ aromatherapy as a natural stress reliever, but could the same approach be used to calm stressed or nervous horses? According to study results from one research team, aromatherapy might have a place in the barn, after all.
Considering thermography to evaluate a horse's legs? Better move that patient inside and shut the doors. Austrian researchers recently learned that wind and air drafts can affect themographic readings of horses’ front legs—very quickly, in fact—potentially leading to false positive or negative results.
Although castrations are routine procedures for many equine practitioners, the risk for complications remains. And while most complications are generally mild, some have life-threatening implications. To better understand these complications, a University of California, Davis (UC Davis), research team recently took a closer look at their prevalence and ou...
A study conducted at Kentucky Equine Research indicates that 72 hours after being administered Salix (furosemide, also commonly called Lasix), active horses had difficulty replenishing calcium levels.
Approximately 20,000 mares are bred in Kentucky each year, which means that it is literally “raining foals” in the spring, as long as things go as planned. Unfortunately, late-term abortions and even abortion storms can occur, resulting in massive economic and emotional mayhem.
Many fractures once deemed inoperable can now be surgically repaired successfully, but management approaches during the critical post-fracture window can have a major impact on outcomes. One equine practitioner reported that veterinarians must be prepared with the appropriate knowledge and equipment to help save these patients' lives.
Raising a child takes a village, notes one African proverb; the collective experiences of a community forming the individual person. Similarly, a growing foal takes its cues from his dam, surrounding herd, and handlers, and care approaches become particularly important when the foal is orphaned. One of the key aspects handlers must consider when raising a...
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 ...
