Insulin Resistance in Horses

Insulin Resistance in Horses Blog

What is Equine Insulin Resistance?

The most basic explanation when discussing Insulin Resistance in horses is that we are dealing with an insulin problem within the horse. When a horse consumes carbohydrates, the pancreas is triggered to produce and release insulin. Insulin regulates and lowers glucose levels in the bloodstream by assisting the transport of glucose into the cells. When we have an Insulin Resistance problem, the cells become resistant to the action of insulin. As blood sugar levels rise, the pancreas secretes more insulin in the attempt to regulate blood sugar. Blood glucose levels begin to rise along with insulin levels when the pancreas reaches the limit of insulin production. 

Horses at Risk of Insulin Resistance

Although all horses are at risk of developing insulin resistance, factors such as age, diet, exercise, and genetics can increase the risk. For example, certain breeds are more conducive to developing insulin resistance. These breeds include:

  • Morgans
  • Pasa Finos
  • Andalusians
  • Arabians
  • Peruvian Pasos
  • Mustangs
  • Ponies
  • Minis
  • Donkeys

Another example is the average age of these horses. If we look at the correlation between age and Insulin Resistance, horses in the 5-15 age range are predisposed to the development of Insulin Resistance. Insulin Resistance is a metabolic issue, so diet and weight also play a significant factor. Horses that are overweight with a body condition score (BCS) between 7 and 9 or who receive diets rich in sugar and carbs have a higher risk of developing Insulin Resistance than a horse who receives regular exercise and a balanced diet.

Since Insulin Resistance is a metabolic problem occurring within the horse, it may be difficult to see the signs of a problem. A common warning sign that can be associated with the development of Insulin Resistance is an obese horse.  Other signs we can look at include:

  • Fast weight gain
  • Inability to lose weight
  • Fatty deposits on the body of the horse
  • Development of a “cresty” neck
  • Loss of topline
  • Increased appetite
  • Excessive thirst and urination
  • Inflammation
  • Frequent bouts of laminitis

Laminitis & Insulin Resistance

Most Insulin Resistant horses are prone to bouts of laminitis. This can be attributed to the abundance of fat tissue, which is extremely common in insulin-resistant horses. In overweight horses, research has uncovered evidence that there is an “insulin resistance” hormone factor produced by the excessive adipose (fat) tissue that contributes to the cells’ inability to uptake glucose from the bloodstream. Adipose tissue may also contribute to higher cortisol levels.  The high glucose and cortisol levels are inflammatory and therefore predispose the horse to laminitis. We highly recommend including a quality hoof supplement in the diet of these Insulin Resistant horses

Preventing Insulin Resistance in Horses

The first ten years of your horse’s life often sets the stage for the development of metabolic conditions. Horse owners should start providing the correct nutrients and a balanced diet to the horse at conception. This balanced diet must be continued throughout the horse’s life to maintain health and prevent future metabolic problems. Other factors that can help prevent the development of Insulin Resistance:

  • Regular work and/or exercise
  • Maintaining a healthy body condition score
  • Feeding grass/hay with a quality hay balancer
  • Refraining from feeding “sweet” feeds or treats

Caring for the Insulin Resistant Horse

There is no cure for Insulin Resistance, but we can help make the life of these horses as comfortable as possible. The first step in this process is to examine the horse’s current diet and develop a feeding plan that will assist the horse in dropping excess weight. This new diet will be focused on reducing the number of sugars and carbs the horse consumes daily. This means no sweet feeds, limited treats, and no grasses with high fructan. Grasses likely to have high fructan content include:

  • Fertilized and growing pastures
  • Pastures stressed from drought or frosts
  • Grazing in the afternoon and evening
  • Tall fescue and ryegrass

Monitored grazing, dry lotting, and grazing muzzles may also be necessary depending on the horse and pasture.

Adding exercise to the horse’s daily routine is the next step. If the horse is not accustomed to exercise, it should be introduced slowly, 2-3 times a week, and built up over time. Eventually, we want the horse to exercise daily with body condition steadily improving.

Supplementation for Insulin Resistance

Supplementation is vital for horses with Insulin Resistance, especially when we begin cutting calories from the diet. We want to cut calories without cutting the horse’s required daily nutrients. If the horse’s diet is not balanced nutritionally, we are not providing the support needed to maintain our horse’s health.

As mentioned above, a quality hoof supplement is essential for insulin-resistant horses to help improve hoof wall density. A denser hoof wall is more resilient to the effects of laminitis and may reduce the risk of founder. One good option is to utilize a hay and pasture balancer alongside a hoof supplement to replace the missing nutrients from the low-calorie diet. Another option is to use a quality hoof supplement and a supplement specifically formulated to support horses with Insulin Resistance.

Does My Horse Need A Joint Supplement?

Farrier Supporting Horse's JointSome of you may already be asking yourself the question, “Should I be providing my horse a joint supplement or formula ?” Maybe you’re noticing that your once energetic horse is slowing down and seems to be stiff and not as nimble. Perhaps your award-winning steed is now taking longer to recover after a competition or a long ride. Maybe your horse is young and thriving and you want to prolong its life and career.

We all want to see our horses live a long, healthy, and enjoyable life, but can a joint supplement really make a difference? Would your horse benefit from receiving this form of joint support?

What is a Joint Problem?

Before we go on any further, we first need to establish what is a joint problem. To make the joint work, it takes the collaboration of tendons, cartilage, bone, soft tissue, and fluid. Any number of these working parts can develop problems and create discomfort in the joint. Some of you may not consider a joint problem an issue until it’s just that – an issue, but a joint problem begins at the first signs of discomfort in the joint. If you ignore the first signs of a problem, it will likely bring more discomfort and develop more issues for you and your horse. If you pay close attention, you can catch the signs of joint discomfort before it develops into something worse or creates irreversible damage.

Does Your Horse Have a Joint Problem?

So, how do we know a problem is there? As the horse owner, you will spend more time with your horse than anyone. You are familiar with your horse’s personality, habits, the way it walks, and so on. You are the first person in a line of checks and balances concerning the health and well being of your horse. Watch the way your horse walks and runs. Keep an eye out for any changes to it’s gate or any initial signs of discomfort. 

These signs of discomfort can especially be seen when you pick up the foot to clean and pick the hoof. Also discuss your horse’s health with your farrier. If you’re regularly maintaining your horse’s hooves, your farrier will be working with your horse’s feet and legs on a regular basis. Your farrier will see the signs of discomfort in the joints as they watch your horse walk or pick up the foot to work on the hoof. Your veterinarian can also assist you in determining if there is an actual problem.Horse Jumping

Preventing Joint Issues and Injuries

It is also important to note that it is much easier to prevent a joint issue than to try and fix one. Prevention is all about protecting the joint before a problem can develop and extending the life and durability of your horse’s joints. Prevention is especially important for horse owners that are regularly using their horse for competition or for work. Competing with your horse in the form of racing, jumping, dressage, three-day eventing, reining, roping, barrel racing, or other athletic competitions and training will regularly apply stress to the joints of your horse. These horses are at the highest risk of developing joint issues or suffering from a joint injury.

Just think of a human athlete. How many NBA, MLB, or NFL stars have we seen fall early in their careers due to an injury involving a joint? Today, these stars are taking precautions to extend the life of their careers. Eating healthier, stretching, taking supplements and staying in shape. It is an investment for them to prolong the life of their careers. We can do the same thing for our athletic horse and extend the life of their athletic careers through their diets, training, and supplementation.

Providing a joint formula like Farrier’s Formula® DS Plus Joint will deliver the ingredients important for the health of the joints and will make the joints more flexible and less prone to injury. These ingredients will also help your horse recover more quickly after a competition and compete at its peak performance. By providing a joint formula early you’re not only preventing future problems but investing in the longevity of your horse.

Joint Supplement for Horses

Supplementing will also help relieve discomfort and pain for a horse that has already developed joint issues. If you have an athletic horse that developed an injury during competition or training, the ingredients in a joint formula will help rebuild and strengthen the connective tissue within the joint. Providing a joint supplement or formula will also support relief to the problem areas, allowing your horse to regain movement that was once too painful to make. This is especially important for the older horse who may be arthritic or have problems due to the build up of past injuries. This will prolong the longevity of your horse, strengthen the joints, and help prevent issues from worsening.

Factors that affect horse joints

You may not be jumping hurdles or taking your horse on week long rides, but it doesn’t mean problems can’t occur. Providing a joint supplement or formula is never a bad idea, especially if you are seeking to extend your horse’s ability to work and compete or wish to address issues developed from injury or age. If you are looking for joint support, we recommend Farrier’s Formula DS Plus Joint.

Farrier’s Formula® DS Plus Joint strengthens the connective tissues of the joints, tendons and ligaments and contains ingredients to promote lubrication of the joints. The inclusion of proline, ornithine, and manganese provide targeted joint support. This product contains the sulfur needed for joint health in the form of the amino acids methionine and cysteine. Farrier’s Formula® DS Plus Joint also provides ingredients important for hoof growth and joint repair without the concern of over supplementation that could occur from feeding a separate hoof and joint supplement. If you have any questions on Farrier’s Formula® DS Plus Joint, proper supplementation, or on joint health please call us at 1-800-624-1873.

How Important are Well Balanced Hooves?

If you own a horse or grew up around horses, you have probably heard the saying “No Hoof, No Horse.” Many of us horse lovers take this statement to heart. Without healthy feet, a horse is unable to be a horse. Running, working, riding – all these activities become a chore; a painful chore at that.

The importance of a healthy hoof is well established, but what about a balanced hoof? Can an imbalanced hoof create hoof related issues? If so, what issues can arise from an imbalanced foot?

Farrier’s on Balanced Hooves

We took this question to Darren Owen, a professional farrier, and asked, “Is a balanced hoof important to hoof health?” Here is what he had to say:

“In my opinion the answer would be yes. The imbalanced foot may become predisposed to the invasion of Thrush or White Line Disease. When the hoof of the horse has greater weight responsibilities placed upon it in an uneven fashion it may distort.

This distortion will promote the separation of the wall from the sole and allow for bacterial / fungal invasion. I recently had an opportunity to speak with a number of farriers on the topic of “Hoof wall separation.” While this conversation was taking place, imbalance and distortion were discussed as a cause of the wall separations that harbor tremendous bacterial / fungal invasions.”

We took the same question to Dave Giza, another professional farrier, and asked him about his experience with imbalanced hooves.

“When I trim and shoe a horse, I always pay very close attention to the placement/balance of the heels, how deep the cleft split of the frogs are (the groove/split that starts in the back of the central sulcus of the frog that transitions up the back of the heels and between the heel bulbs), and to the movement of the heel bulbs themselves. 

If a horse has well balanced feet, with both heels contacting the ground at the same time, there will be very little independent movement of the heel bulbs, frog cleft/split will be shallow, and the horse will be sound.  If the trim is out of balance, with the medial side hitting first and then the lateral side or vice versa, there will be independent heel bulb movement and separation that will cause lameness issues.

Separation of Heel Bulbs

If you look at the hoof from the back and visualize a triangle (the base of the triangle having points at the medial and lateral side of the hoof and the top of the triangle at the apex of the frog cleft), this will present a better picture of what is actually happening.

When the base of the triangle hits evenly on the ground, there is no movement at the top of the triangle, just compression as the bulbs move as one unit.  However, if the triangle base hits the ground, one side first followed by the other, the top of the cleft will be forced to move from right to left or vice versa.

This imbalance will cause tearing and or shearing of the soft tissues between the heels, and deep heel splits that cause the heel bulbs to gap open and allow debris to enter into the cleft gap.  Now the stage has been set for infected/swollen sheared heels.  The debris that is lodged deep into the frog cleft becomes Thrush, the constant independent movement of each heel bulb and shearing causes the heel bulbs to become irritated and swell closed, the developing thrush is entrapped, and the result is a very sore heeled, lame horse.”

“I recently drove 700 miles to treat a horse named Cody diagnosed with equine Canker; however, Cody was misdiagnosed and rather suffered from infected, sheared heels.  Without a doubt, Cody’s issues were caused by improper trimming.

Upon examination, I found that the heels of each hoof were out of balance, causing heel bulb displacement with deep frog clefts penetrating up into the hairline and entrapping infection.  The infection not only compromised the heel bulbs, but had also started to compromise each frog.  I trimmed, balanced, thoroughly cleaned and treated each sheared/split heel on Cody’s hooves.”

Farrier Conclusion

Both farriers agree, balanced hooves are important to hoof health. As a farrier, it is extremely important to properly trim and balance each hoof. If this is not done correctly, more issues can arise and create further problems for you down the road. Horse owners must also pay close attention to this detail and do their part in picking and cleaning the feet on a regular basis. If you believe your horse’s hooves are imbalanced, do not be afraid to bring it up to your farrier or to seek the opinion of another farrier or veterinarian. If your horse’s hooves were trimmed improperly, it is important to have this fixed as soon as possible. A hoof supplement combined with a safe anti-microbial hoof clay and liquid will help the hooves recover from cracks, splits or other hoof related issues that arise from the hoof imbalance. Using a hoof supplement will also promote the health of the hoof and increase its growth rate.

Hoof Care Doesn’t Stop in the Winter.

Worse walking in snow

Winter is in full force and Jack Frost is blanketing many of our pastures with snow, freezing rain, and ice. Many of us are now concentrated on keeping our horses healthy, while maintaining body condition through this cold spell. We all have different routines we practice to keep our beloved horses as comfortable as possible during these months. We can debate all day between blankets VS a horse’s natural coat, or even more barn time VS more pasture time – but the one thing we cannot argue about is that proper hoof care doesn’t stop in the winter. Providing a balanced diet, staying on top of any hoof problems caused by the environment, and routine farrier work is a year-round effort.

Worse walking in snow

How Winter Affects the Hoof

It doesn’t take an expert to see that any amount of snow is going to leave our pastures wet and muddy, and as we have discussed in previous articles, wet and muddy conditions can create the perfect environment for “hoof eating” microbes to thrive. Prolonged exposure to water can soften the hoof capsule, leading to stretching and separation of the white line area. Regardless of how much pasture time you are allocating to your horse during the winter, ensure to properly clean and dry the hooves before moving your horse back into the barn.

Even if your horse is not spending a lot of time out in the cold environment, it is still important to regularly clean your horse’s hooves. Some horse owner’s may choose to restrict pasture time due to the freezing weather. Extended periods of time in a stall might keep your horse warmer, but this confinement can create hoof problems as well. While stalled, your horse will be standing in its own waste. This exposes the hooves to different bacteria that will affect the health of the hooves. Regularly cleaning your horse’s hooves and maintaining a clean environment for your horse can help prevent problems, but issues such as Thrush or White Line Disease can develop if left unchecked.

Hoof Maintenance in the Winter

Farrier Applying Hoof Topical for Thrush

Even with regular cleaning, sometimes you may need a little extra help maintaining the health of your horse’s hooves. Regularly feeding a quality hoof supplement, such as Farrier’s Formula®, will provide the nutrients your horse needs to promote stronger and healthier hooves. These stronger hooves will be more resilient to problems such as White Line Disease and will help prevent the softening of the hoof capsule. Using non-caustic antimicrobials, like Farrier’s Finish® and Life Data® Hoof Clay®, may be applied after cleanings to help fight and kill any “hoof-eating” microbes. These products will also help maintain hoof quality, and are non-caustic to you and your horse. We also recommended talking with your farrier and veterinarian to create a plan to properly care and maintain your horse’s hooves. Regular farrier and veterinarian visits are always recommended. Farrier visits should not be eliminated because of the winter season.
