Insulin Resistance: Variation in Blood Test Levels 
A blood sample is usually a key step in diagnosing a horse as insulin resistant. But a recent study showed that one sample might not give enough information because the horse’s blood sugar and insulin fluctuates daily.

Researchers Track Body Condition, Metabolic Conditions by Discipline 
The sport in which horses participate often dictates the body condition in which they are maintained. Polo ponies are typically sleek and trim, their fitness evident in a tight, tucked-up appearance. The same can be said of most racehorses. Pleasure horses, those mounts used to poke around trails and forests, are sometimes softer and less muscular, ...

Metformin a Therapy in Progress for Equine Insulin Resistance

Metformin is an oral antihyperglycemic drug used to treat type-2 diabetes mellitus in humans. It also appears to increase insulin sensitivity ...

Fiber in Hay: What's the Magic Number? 
Horses evolved to eat a lot of fiber, spending up to 17 hours a day grazing various forage plants. But not all fiber is created equal, especially when it comes to hay.
Hay carries a few challenges compared to living forages. One, compared to fresh forage, dry hay lacks the moisture needed to move fiber along the digestive tract. Unlimited access ...

Slimming Down 
In this age of plenty, it is not uncommon to see horses carrying too much body fat. Such an individual exceeds what we might call pleasingly plump; in other words, he is fat. When running your hands across the horse's sides, you won't feel any ribs beneath his flesh. Often a fat horse has developed a cresty neck, and if you can stand on a fence ...

A Better Weigh 
We've all seen horses around the barn, on neighboring farms, or quite possibly in our own barn that are a little, shall we say--heavy. But what exactly is heavy? For that matter, what determines if a horse is thin? Sure, it's easy to point out those horses at either of the extremes, but for those in between there can be gray areas.
In the early 1980s, ...

Feeding Horses With Laminitis 
What do you feed a horse with laminitis? Nothing, plus a bit of hay is a common diet. Does it work? Yes, and no. Expert opinions and modern research are showing that, in some cases, nothing might be the wrong answer when it comes to feedstuffs, and that simple flake of hay might not be as harmless as you think.

Obesity and Cushing's Disease 
Cushing's disease has been around for a long time in people, horses, and other animals.

Deep Down Clean 
Have you ever watched two horses in a pasture or paddock, contentedly scratching each others' withers or rumps with their teeth? They do this because it feels good. If scratching each other with their teeth makes them feel good, it stands to reason that massaging their skin with a brush will also make them feel good.

At Home On The Range: Dude Horses 
While many of our horses do some kind of work for a living, the work usually consists of a couple of hours a day, three to five days a week. Many of our horses are ridden far less than that, and we don't really think of them as "working" for their living as did horses of yesteryear. But there are horses out there which do put in a full day, whether ...

Weighing In 
Accepted wisdom in the horse world tells us that an "average" light horse weighs about 1,000 pounds, or 450 kg. A draft horse, upwards of double that. But does that rather arbitrary figure really mean anything? After all, what is an "average" horse? To a dressage competitor, it might be a 17-hand warmblood, while to a cutting horse enthusiast, it might ...
