Joint
health is such a concern these days, especially for owners of performance
horses, that it deserves some serious attention. In this issue,
we'll be discussing ways to create and maintain good joint health
in young horses. While many horse owners now consider it normal
and acceptable to give joint injections to 4 and 5 year old horses,
my clinical experience shows me that horses should not need this
kind of support, if at all, until much later in life. With excellent
management and nutritional support, it's possible for even hard
working performance horses to have strong healthy joints for many
years.
What Causes Joint Problems? To understand how to create
and maintain good joint health, you have to understand the causes
of joint problems. Basically, if the joint fluid stays thick, it
can properly lubricate the joint and keep the cartilage healthy.
It's when the joint fluid becomes thin that joint problems develop.
What causes joint fluid to become thin? Lack of antioxidants.
Horses start developing joint problems (whether they are noticeable
yet or not) when they begin training or exercising hard. When horses
exercise hard, their bodies create more free radicals, which then
uses up their supply of natural antioxidants at a faster rate. When
the body has more free radicals than it has antioxidants, one area
that suffers is the joint fluid, which changes in consistency and
becomes thin. At this point, the joint fluid can't properly lubricate
the joint, causing wear and tear on the cartilage. As the cartilage
wears down, the joint becomes less and less stable. To compensate,
the body lays bone down around the joint the stabilize it. At this
point, the joint develops calcium deposits and you can see structural
changes on X-rays.
Creating Joint Health from the Beginning
One
of the best ways to create a foundation for joint health is to start
before the foal is even born. Make sure that the pregnant mare has
plenty of vitamins, minerals, and trace minerals throughout the
pregnancy so that the foal is develops good bones and joints. Once
the foal is born it is more difficult to supplement trace minerals
as he is nursing and mare's milk contains mainly macro minerals
like calcium. Be sure and start the foals on good micromineral supplements
as soon as they start to eat some grain especially if good quality
grass is not available.
One of the best and easiest ways to ensure that mare and foal
get all the micro nutrients they need is to feed blue green algae
because it's balanced in calcium and phosphorous. You can also feed
the pregnant mare some alfalfa for its micro nutrient and calcium
content, but don't feed alfalfa to young foals since it's not balanced
in terms of calcium and phosphorous.
Joint Health in Growing Horses
To keep joints healthy in young horses, feed plenty of micro
nutrients (from blue green algae, for instance), and avoid overloading
the diet with too many calories. Studies have linked diets high
in carbohydrates with developmental bone problems like OCD (Osteo
Chondrosis Dissecans). Plus, overfed young horses that are too fat
will overstress their joints with the extra weight. As a general
rule, on young horses I like to be able to feel ribs but not see
them. You'll also want to monitor their exercise regimen carefully.
Young horses are not fully developed until they are 4 years of age.
While you can certainly start working them earlier, they are not
strong enough to handle heavy work until age 4.
Joint Health in Horses Ages 4 to 6
At this age, horses are able to handle a full training schedule
and start exercising heavily. To support this transition, feed plenty
of good quality micro and macro nutrients, along with minerals and
trace minerals. Since your horse is exercising hard, you'll also
want to add in antioxidants to neutralize the free radicals being
produced from the heavy exercise. Good antioxidants include blue
green algae (which has beta carotene), Tahitian noni juice, super
oxide dismutase (found in Cell Tech's Super Blue Green Algae), coenzyme
Q10, grape seed extract, omega-3 fatty acids, and certain minerals
such as sulphur (found in the supplement MSM). Stick with natural
antioxidant supplements (i.e., those in their natural form) as much
as possible since the body can use naturally occurring antioxidants
more efficiently than synthetic ones.
At this point in your horse's life you want to focus on good
nutrition and antioxidants to prevent cartilage damage. Feeding
joint supplements like glucosamine, which is a single component
of the cartilage, is not as helpful. It will not prevent cartilage
damage-antioxidants do a much better job of it. In fact, you want
to delay the use of joint supplements as long as possible using
the methods discussed above. Please note that it is not normal for
horses to develop joint problems at this age. Joint problems at
this age indicate a lack of nutrition, specifically antioxidants.
There is an intravenous injection that supports the joints called
Legend, which is hyaluronic acid. Hyaluronic acid can also be injected
into the joints and is one substance that can be used to prevent
cartilage damage and reduce inflammation after a joint has already
been damaged. Hyaluronic acid will thicken the joint fluid and decrease
inflammation in the joint (which is the result of free radicals
and can thin the joint fluid). If your horse a little sore after
a particularly hard workout or show, you may want to consider giving
him Legend instead of going immediately to a joint injection. Remember
that you can only give your horse so many joint injections in his
lifetime, and that each injection increases the chances of introducing
infection. Overall, if you have the choice, use excellent nutrition
and antioxidants before resorting to joint injections.
