Sulfur Over Supplementation in Horses

Why is Sulfur Important for Horses?

The connective tissues of all mammals are rich in the mineral sulfur. The skin, hair, ligaments, tendons, cartilage, and hooves of horses are composed of connective tissue. Collagen is the protein of connective tissue, and is the most abundant protein in the mammalian body. Sulfur, an important component of collagen, is required for both joint health and, in horses, healthy hooves. One dietary source of sulfur is methionine. Methionine is an essential amino acid that the body can convert to another “sulfur-containing” amino acid called cysteine.

Farrier Hot Shoeing Horse
*Sulfur is abundant in the hoof. The “rotten egg” odor produced during hot-shoeing is the smell of sulfur gas resulting from burning the sulfur – rich connective tissue proteins of the hoof.

Once converted, cysteine provides the sulfur “welds,” or crosslinks, necessary for healthy collagen and, thus, a strong connective tissue infrastructure. The lack of sulfur, or methionine, in a horse’s diet is known to lead to structural weakness in the:

  • Ligaments
  • Tendons
  • Bones
  • Joints
  • Hooves

However, too much sulfur in a horse’s diet can lead to over-supplementation, weaken joint strength, and affect hoof quality.

How does Over-Supplementation Occur?

Many hoof supplements contain sulfur in the form of the amino acid methionine. The added methionine balances the relative deficiency of methionine in the typical equine pasture and hay diet. Most equine joint supplements contain MSM, or methylsulfonylmethane, which contains around 34% sulfur. Sulfur over-supplementation can result from feeding a hoof supplement with methionine along with a joint supplement containing MSM. Excess sulfur in the diet has been shown to impair the proper absorption of copper. Copper, along with vitamin C, is necessary for collagen formation and the development of healthy connective tissue for strong hooves and joints.

Equine Sulfur Over Supplementation

How can Over-Supplementation be Avoided?

There are other negative effects of over-supplementation, and it is generally not a good idea to give more than one vitamin/mineral supplement to a horse. If the horse has joint problems in addition to hoof problems, joint supplements without additional sulfur can be given in addition to the hoof supplement. Avoiding supplements that duplicate nutrients is key to reducing the risk of over-supplementation. Providing a single balanced supplement, backed by research and years of proven effectiveness, is recommended and can lead to a healthier, happier horse.

Feeding for Hoof Health

Nutrition’s Role in Hoof Care

In this article, we want to focus on the role that nutrition plays in hoof health.

Consider the following scenario, where two horses are:
1. In the same environment and barn
2. Fed the same diet
3. Working at the same level
4. Competing in the same discipline
5. Trimmed by the same Farrier
6. Cared by the same person
However, one has healthy feet, and the other has poor-quality hooves.

Dietary Factors

In the case above, since all factors are the same, we may want to take a closer look at nutrition. Even though both horses are receiving the same diet, their genetic makeup plays a big role in how nutrients are absorbed and utilized.

When horses have poor feet due to dietary factors, it can be hard to determine the exact cause. However, you can assume that your horse is: 

  • Not receiving the correct nutrients
  • Absorbing nutrients insufficiently
  • Another dietary factor is interfering with nutrient utilization

It is of great importance to maintain correct ratios between all nutrients to prevent one nutrient from interfering with the absorption and utilization of another. When balancing diets it is just as important to prevent excesses as it is to correct deficiencies.

Hoof problems? Where should you start?

1. Provide hay and/or pasture as the basic diet
2. Provide a quality hoof supplement
3. Provide free-choice loose salt
4. Allow access to fresh, clean water

If your horse does have a noticeable hoof problem, and you begin a nutritional program to solve it, you should see a positive difference emerging from the coronary band within 8 to 10 weeks. If not, you should re-examine your nutrition and management program immediately with the help of an equine nutritionist.

Recommended Hoof Supplement: Farrier’s Formula® Double Strength

What should you avoid?

1) Avoid using several supplements
o Most supplements, when fed in conjunction with others, can lead to over-supplementation, nutrient interferences, and even create toxic levels of some ingested nutrients. Ask your veterinarian if it’s safe to feed one supplement with another.

2) Avoid high-bran diets
o Wheat, rice or other grains

3) In the vast majority of cases biotin alone is not enough to correct poor hoof quality.
o There are many other nutrients that affect hoof quality.

The key is fortifying hoof health without producing nutrient excesses or deficiencies. When choosing a hoof supplement, ask your farrier which one does he or she recommends. Chances are, it’ll be Farrier’s Formula®: the #1 recommended hoof supplement by Farriers in the United States.

Case Report: Laminitis

Summary

A 13-year-old Quarter Horse gelding was treated for severe laminitis with Animalintex poultices, Farrier’s Formula®, Pegasus Laser Therapy, and Soft-Ride Boots, which allowed for the growth of new hoof walls after the old hoof walls had rotated away and sloughed off. These therapies to increase circulation and provide nutrition to the hooves were successful in returning the gelding soundly to his previous level of work after 18 months.

Punctured
Right Hind Sole 07/02/2012

Introduction

Laminitis in its most simple definition is inflammation of the sensitive laminae of the hoof wall. The cause however can vary from trauma, to grain overload, to toxins, and beyond. This case study is meant to show that even the most severe of cases have a chance of survival and return to work if we attempt to help the body heal itself rather than use our traditional treatment regimes. However, the key to success relies on the presence of a willing and diligent owner, veterinarian, farrier, and above all a patient that is willing to be treated.

Left Fore Medial
Left Fore Medial 07/18/2012

Nutrition

In conjunction with antibiotic treatments, he received daily Probios. Free-choice grass hay was available at all times. Daily ration consisted of ½ cup Life Data® Forage Balancer. Hoof supplement consisted of 1/2cup Farrier’s Formula® Double Strength. Fresh water was also available at all times.

Hoof Resection
Right Hind Wall Resection 8/20/2012

Results

  • Hooves remained intact and grew at an increased rate.
  • The hoof wall that was present at the onset of the laminitic episode rotated away from P3 on each hoof. (see Left Fore Medial 7.18.2012).
  • The dead soles were removed at the beginning of the 3rd month of treatment. (see Right Hind Sole 7.2.2012).
  • The outer hoof walls detached at 4.5 months of treatment. (see Right Hind Wall Resection 8.20.2012).
  • New hoof wall grew in at the correct angle and did not associate with the old hoof wall. Hooves continued to grow and at 11 months all hooves had grown to touch the ground. (see Right Hind Lateral 3.30.2013). He remained tender on the front hooves but was able to have his back boots removed at that time.
  • At 18 months aluminum Natural Balance shoes were applied to his front hooves and he was able to trot off sound.

Discussion

The combination of Animalintex poultices, Farrier’s Formula®, Pegasus Laser therapy, and Soft-Ride Boots led to a full recovery of a horse that should not have survived. Animalintex poultices allowed for debris and waste products to be removed from the body without the need to recirculate through the body. Farrier’s Formula® provided the nutrition needed for increased hoof growth. Pegasus laser therapy allowed for increased circulation to get the nutrients where they were needed most, as well as provide pain relief from standing in the “founder stance”. Soft-Ride Boots provided support and protection to the bandaged hooves as well as increasing circulation during the times he did choose to stand.

Nutrients that Influence Hoof Health

Modern Horses Grazing

The nutritional demands of domesticated modern horses are much different than the nutritional demands of wild horses. A myriad of feedstuffs and supplements have been developed and marketed in reaction to these changing needs. While proper supplementation can provide numerous benefits, insufficient or excessive supplementation of any nutrient can be detrimental for hoof health.

Amino acids

Methionine, proline, glycine, and glutamine are some of the amino acids that are major protein building blocks of healthy connective tissue (hooves are primarily composed of connective tissue). An imbalance of the amino acid ratio leads to inefficient protein production.

Tyrosine and Iodine
The amino acid tyrosine and the mineral iodine are components of thyroid hormone. A deficiency of either of these nutrients can lead to low thyroid function, obesity, and poor hair coat and hoof quality. The relationship between tyrosine, iodine, hoof problems, and obesity is very strong.

Methionine
Methionine is important for the proper utilization of lipids and for building the sulfur crosslinks that add strength to connective tissue. Methionine is a sulfur-containing amino acid that is commonly deficient in grasses and grains.

Vitamins

Vitamins are necessary for many metabolic processes and the general health of the horse and the hooves.

Vitamin A
Either an excess or deficiency of vitamin A can result in poor hoof quality and predispose the invasion of microorganisms into the hoof wall, creating a hoof defect pattern in which the outer hoof wall flakes off. Hair-like projections emerging from the hoof wall or the sole of a horse’s hoof is also an indicator of Vitamin A excess or deficiency.

Vitamin A Deficiency in the Hoof

Vitamin C
Vitamin C, along with copper, serves as a catalyst in the formation of strong and healthy horn. Supplementation of vitamin C, or ascorbic acid, is traditionally believed to be unnecessary in horses. However, research conducted by Dr. Frank Gravlee, founder of Life Data Labs, established that stabled or stressed horses often have minimal blood levels of ascorbic acid and can therefore benefit from vitamin C supplementation.

Biotin
Biotin is necessary as a coenzyme for a multitude of metabolic functions, and is significantly important in the proper growth and strength of connective tissue. Supplementation of biotin is safe because it is a water soluble vitamin, which means biotin is not stored in the body in any significant amounts. Biotin is found naturally in pasture grasses and in many feedstuffs fed to horses. Hindgut microbes normally manufacture sufficient biotin to meet the horse’s daily requirement.

Minerals

Minerals are responsible for the structural integrity of the body, energy production, immune health, and perform other functions such as co-factors for enzymatic and metabolic reactions.

Copper
Copper is a mineral that is an important component of a multitude of metabolic functions. A copper deficiency leads to a number of abnormal conditions, including defects in the pigmentation and strength of the hooves. Forages can be copper deficient, especially if grown in high rainfall areas.

Zinc
Zinc is a mineral required for the healthy maturing of keratin – a major component of the outer layers of dermal tissue. Proper keratin formation is important for wound healing, skin health, and hoof structure. Zinc can be present in less than ideal levels in forages.

Calcium and Phosphorus
Calcium provides the adhesive “welds” between cells. Excess phosphorus in the diet can interfere with calcium absorption. In the presence of hoof problems, bran should not be fed. Whether it’s from wheat, rice, oats or other grains, bran contains phytates. Phytates block the absorption of calcium predisposing the horse to a calcium deficiency and other mineral imbalances. Calcium deficiency results in crumbly hoof horn.

Sulfur
Sulfur is required to build the strong cross links necessary for healthy hoof horn. However, excessive sulfur interferes with copper metabolism leading to weak connective tissue structure and poor hoof quality.

Selenium
We are unaware of a selenium deficiency causing poor hoof quality. A selenium deficiency in horses will lead to other problems, such as muscle deterioration, long before any effects could potentially develop in the hooves. However, horses supplemented with excessive selenium develop a lack of structure in the hoof horn. The excess selenium replaces the stronger sulfur bonds, resulting in weak hoof horn. As selenium toxicity progresses, the outer hoof wall becomes brittle, noticeable horizontal rings appear, pain develops at the coronary band, and the outer hoof wall may slough.

Selenium Toxicity in the Hoof

Fatty Acids and Phospholipids

Fatty acids and phospholipids (phosphatidylcholine) add strength and pliability to connective tissues of the hooves, are critical for healthy moisture balance, and are necessary for a healthy, shiny coat. Phospholipids are important for healthy cell membranes.

We are faced with the nutrition challenge to fortify the horse’s hoof health without producing nutrient excesses and/or deficiencies. When choosing a hoof supplement, ask your farrier which one they recommend. Chances are it’ll be Farrier’s Formula®, the #1 recommended hoof supplement by Farriers in the USA.

Amino Acids in the Equine Diet: Methionine and Cystine

There are twenty amino acids known that make up the building blocks for mammalian body protein. Approximately one-half of the amino acids are essential (this means the body is unable to make those nutrients; therefore, the nutrients must be ingested). Methionine is an essential amino acid that can be converted to cystine by the body.

Cystine and the Horse

Cystine is important because it furnishes the sulfur crosslinks that are necessary for healthy collagen, thus strong hoof infrastructure (hoof, skin, hair, ligaments, tendons, and cartilage). A certain quantity of essential amino acids can be manufactured by the micro organisms in the hind gut of the equine.

Methionine

Most hoof supplements containing methionine is the DL-methionine form. L-methionine is the biologically active form amounting to approximately 50% of the total DL-methionine. A supplement containing 6,000 milligrams of DL-methionine would contain 3,000 milligrams of the biologically active L form. There is no data on the equine requirements of methionine; however, the average requirements for other species converted to the metabolic size of a horse amounts to approximately 3,000 milligrams of L-methionine per day.

Because methionine is readily converted to cystine by the liver in mammals it is necessary to supplement only methionine to fulfill the methionine/cystine requirement.

Forage Balancers: Fortifying the Equine Forage-Based Diet

What is a Forage Balancer
What is a Forage Balancer?

What is a Forage Balancer?

A forage balancer is a supplement that fortifies a horse’s forage-based diet with essential nutrients. It helps provide a balanced nutritional profile for your horse by supplying vitamins, minerals, amino acids, and fatty acids that are often lacking in most equine diets. A true Forage Balancer does not contain added calories, sugars, or carbohydrates. It acts as the feeding program for the horse, eliminating the need to feed compound feeds. This gives horse owners more control of calorie intake without risk of over- or under-supplementation. With a Forage Balancer, horse owners can feed horses individually and adjust calorie intake to meet the energy requirements of each horse.

What Type of Horses Can Be Fed a Forage Balancer?

Any Horse Can Utilize a Forage Balancer
A Forage Balancer Can Be Utilized For Any Horse

A Forage Balancer can be utilized for any horse, regardless of age, breed, or activity level. Easy Keepers, Hard Keepers, backyard leisure horses, and Performance Horses would all receive the nutritional benefits of a quality Forage Balancer. Forage Balancers are especially recommended for easy and hard keepers to help maintain body condition.

Mares and Growing Horses require additional nutritional support compared to the average horse. Feeding a Forage Balancer formulated specifically to support Broodmares and Foals is recommended to help support fetal growth, lactation, and weight management. The unborn foal also receives nutritional benefits when fed to the Broodmare.

Horses with Metabolic Issues, such as Insulin Resistance, Cushing’s Disease, and/or Laminitis, do not need a Forage Balancer. Specialized formulas are available for these horses. These formulas replace a forage balancer to provide nutritional support for these Metabolic issues.

Complete Feeds VS Forage Balancer

No forage provides every nutrient your horse needs. For example, wild horses must roam long distances to meet nutritional requirements through grazing. The domesticated horse is limited and only receives nutrients from the pastures and forages that horse owners provide. This is where a Forage Balancer comes into play, fulfilling the nutritional gaps in the natural equine diet.

Equine Complete Feeds
Complete Feeds May Contain Excess Fats and Sugar

Many horse owners utilize Complete Feeds or products that combine a complete feed with a Forage Balancer in their feeding programs. Complete Feeds are easy to use, affordable, and provide energy for the horse. However, they may contain excess fats and sugar and often lead to a diet rich in fats and carbohydrates. Complete feeds also adhere to the “all-in-one” concept, tethering calories and nutrients together. This creates opportunities for over- or under-supplementation, when horse owners adjust feeding levels to manage body condition. This most commonly occurs when feeding Easy Keepers and Hard Keepers.

A true Forage Balancer does not tether nutrients and calories, making it easier to maintain body condition. The average backyard horse and Easy Keeper can be sustained alone on Forage and a quality Forage Balancer. Whole oats, copra, beet pulp, and/or vegetable oil can be added for horses requiring additional calories, such as Hard Keepers and Performance Horses. 

Benefits of a Forage Balancer:

  • Brings the Horse Back to its “Basic” Forage Diet
  • Separates Calories from Nutrients
  • Low in Calories, Starches, and Carbohydrates
  • Reduces the Risk of Metabolic Disorders
  • Increases Feed Utilization of Hay and Pasture
  • Helps Maintain Proper Body Condition Score
  • Helps Manage Calorie Consumption
  • Eliminates Feeding Complete Feeds

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.

Clinical Signs of Equine Insulin Resistance

Overweight Horse
Horse with a Body Condition Score of 8

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.

Correlations Between Equine Hoof and Joint Health: PART 1

Equine Hoof and Joints

Have you ever considered the substantial influence the health of our horse’s hooves and joints have on one another? For example, can poor hoof quality negatively impact joint health? Can a joint injury add extra strain to the hoof? It is easy to look at our horse’s health from a narrow perspective, only considering the problem at hand. When it comes to the longevity and comfort of the horse, we need to look at the whole picture. The horse’s joints and hooves function together in its movement and balance. When one is afflicted, the other is often affected as well.

Effects from offloading, poor nutrition, hoof balance, terrain, and body condition accumulate over time, weakening the horse’s extremities and creating real problems in the horse’s locomotion. These influences become even more important for older horses, who are more susceptible to joint pain, arthritis, and hoof problems such as laminitis. In part one of this blog, we will discuss the impact that body condition and nutrition have on the health of the hooves and joints.

Overweight Body Condition

Obesity continues to be a growing problem in the horse community. Approximately 50% of the horse population in the United States is considered overweight. It is almost guaranteed that an obese horse will eventually develop hoof and/or joint problems. The additional weight increases the strain and pressure heaped onto the hooves and joints. The excess weight will also boost the risk of problems developing when combined with unbalanced hooves, frequent exposure to hard terrain, and offloading. In addition, most of these horses also do not receive enough exercise or balanced diets. This sedentary lifestyle does not provide the needed exercise to maintain joint strength and quality. Providing an imbalanced diet only adds to the problem. Nutrient and caloric excesses in the diet are typical in overweight horses and can have many consequences on the health of the hooves and joints. Common problems that can occur in obese horses are:

  • Laminitis
  • Hoof “pancaking”
  • Joint inflammation
  • Hoof Abscesses
  • Joint related injuries
  • White line separation
  • Arthritis
  • Poor hoof and joint quality
  • Sore joints
Horse with Body Condition Score of 8
Overweight Horse with a Body Condition Score of 8

Overweight Body Condition: What to Do?

The most impactful move horse owners can make to reduce their horse’s body weight is to return to the “basic diet” of the horse. Remove all complete feeds, sweet feeds, and treats from the horse’s diet. Utilize grass and hay as the cornerstone of your horse’s feeding program. We also recommend including a quality hay and pasture balancer, such as Barn Bag®, for nutritional support. This approach allows horse owners to control the number of calories their horses receive while still providing the essential nutrients the horse requires. Adding regular exercise to the horse’s daily regime is also extremely important. Start slow and allow the horse to build up to the new activities. The last thing you want to do is cause an injury by pushing your horse too hard and too fast.

Nutrition & Supplementation

The health and quality of your horse’s hooves and joints are reliant on proper nutrition and a balanced diet. In fact, poor hoof quality is one of the first signs of poor nutrition. The hooves, skin, hair coat, and ligaments supporting the joints are all made of connective tissue. If the hooves are impacted by poor nutrition, all other connective tissues of the horse will suffer, including the joints. Although nutrient imbalances can develop in any horse, overweight horses are highly susceptible to imbalances and the resulting hoof and joint issues.

Nutrient deficiencies and excesses in the diet will hinder the development of hoof and joint quality. One example is a deficiency in Vitamin A which creates a hoof wall defect where the hoof wall “flakes” away. Another perfect example is sulfur. A deficiency of sulfur-containing amino acids could lead to structural weakness of the ligaments, tendons, joints, and hooves. However, too much sulfur in the diet can have a negative effect on connective tissue strength. When hoof and joint quality are poorly affected by nutrition, we can expect:

  • Higher risks of thrush, white line disease, and microbial invasions
  • Hoof abscesses
  • Laminitis
  • Deteriorating joint health
  • Joint inflammation
  • Variations of poor hoof quality
  • Risks of injury
  • Hoof defects and deformities
  • Arthritis

Nutrition & Supplementation: What to Do?

Providing a balanced diet supported with essential nutrients will have one of the most significant impacts on your horse’s hooves and joints. Adding a quality hoof supplement to your horse’s feeding program will also benefit all dermal tissue of the horse, including the hoof and the connective tissue of the joint. A hoof supplement will build, improve, and support hoof quality to make it more resilient to many hoof problems.

Horse owners can also utilize a joint supplement to support joint health further. Although, feeding a hoof supplement with a separate joint supplement can have risks of sulfur over-supplementation. To avoid over-supplementing, utilizing a combo product to support hoof and joint health, such as Farrier’s Formula® DS Plus Joint, is highly recommended. Farrier’s Formula® DS Plus Joint is balanced to support the hoof and joint without the risk of over-supplementation. Starting horses on Farrier’s Formula® DS Plus Joint from an early age is also a great preventive measure.

Prevention Versus Treatment

Preventing a problem is always better than treating a problem. Protecting and building quality hooves and joints begins at conception. Waiting to tackle a problem until there is a problem can be time-consuming, costly, and have lasting effects on your horse’s health. The key to prevention and extending the longevity of your horse begins with:

Although nutrition and weight management are major factors in hoof and joint health, there are other factors that still need to be considered. In part 2 of “Correlations Between Equine Hoof and Joint Health,” we will dive further into this subject to discuss offloading, terrain, and unbalanced hooves. Contact us if you have any questions about this article or the supplements mentioned. Consult with your farrier and veterinarian immediately if you believe your horse has a hoof or joint problem.

Anhidrosis in Horses. What Can be Done?

Horse with Anhidrosis

What is Anhidrosis in Horses?

Anhidrosis in horses can be described as the inability or reduced capacity to sweat. Horses regulate their body temperature, much like we do, primarily through the evaporation of sweat. Anhidrosis can tremendously affect the horse’s ability to work, perform, and function. Without the full capacity to sweat, the horse is in danger of:

  • Overheating and having a heat stroke
  • Organ and muscle damage
  • Death

Is Your Horse at Risk?

The prevalence of anhidrosis in horses has been estimated to be between 2% to 6% of horses. All breeds, ages, sexes and coat colors are at risk. Interestingly, the birth and growth of a foal in a hot and humid climate does not reduce the risk of developing anhidrosis.

Due to varying degrees of sweating between affected horses, anhidrosis can be difficult to recognize by the horse owner or veterinarian. The incidence and potential severity of anhidrosis are higher in hot and humid climates, although anhidrosis can also be an issue in cooler dry areas. Chronic anhidrosis has been linked to atrophy of the sweat glands leading to a permanent loss of sweating ability.

Recognizing Equine Anhidrosis

Anhidrosis affects horses in different degrees, making recognizing and diagnosing the problem more difficult. For example, one horse may completely stop while other horses might only have a slight reduction in sweating capacity. Only certain body areas of the horse may sweat while others are dry – the horse may still sweat under the mane and under the saddle pad.

Brushing Horse Coat

Here are a few key symptoms of equine anhidrosis:

  • Heavy or labored breathing
  • Flared nostrils
  • Horse begins to pant with an open mouth
  • Body temperature over 104 degrees Fahrenheit
  • Increased heart rate and blood pressure
  • Noticeable lack of sweat – other horses may be
    sweating profusely
  • Lack of energy
  • Refusal to work
  • Desire to seek and remain in the shade
  • Coat is dry to the touch
  • Dry or itchy skin (chronic anhidrosis)

What Causes Anhidrosis in Horses?

Unfortunately, the mechanisms are unknown, and research into the cause continues. Many researchers and veterinarians believe the cause is attributed to:

    • A genetic condition has been implicated – research is currently in progress at the University of Florida Large Animal Hospital
    • Some horses may be born with a reduced number of functional sweat glands
  • Nutrition and Diet
    • Excesses and deficiencies of nutrients can affect the skin and hair coat. Many of these nutritional-related issues may also contribute to anhidrosis.  

Treating Equine Anhidrosis

If your horse is becoming overheated or exhausted, there are short-term steps you can immediately take to help cool down the body temperature:

  • Move horse to a shady area or ventilated stall
  • Use portable fans or air conditioning
  • Hose down horse with cold water
  • Provide plenty of cold water to drink

No cure has been discovered for anhidrosis. Products available on the market may help enhance the horse’s ability to sweat. Life Data® Sweat Formula contains active ingredients that have produced positive results in most horses with anhidrosis.

Life Data® Sweat Formula is a new product developed from several years of anhidrosis research at Life Data Labs, Inc. The in-house Life Data® research lab utilizes blood tests and a sophisticated software program to determine the relationship between blood work results and specific conditions in horses. Equipment in the lab analyzes macro and trace mineral content of whole blood in horses to discover any correlations between certain minerals and specific conditions. Through this current research, Life Data® has discovered several consistent correlations between blood test deficiencies and excesses within a group of horses diagnosed with anhidrosis.

Life Data® Sweat Formula

Life Data® used this research to develop an anhidrosis formula for non-sweating horses. This formula delivers a combination of essential fatty acids, amino acids, vitamins, and minerals to balance the deficiencies and excesses in the typical anhidrotic horse. The active ingredients will help improve skin and sweat gland condition to help regenerate the horse’s ability to sweat. For example, the fatty acids delivered in Life Data® Sweat Formula helps restore the lipids of the sweat gland membranes, which may help the transfer of fluids out of the sweat glands.

Depending on the individual horse the product may require daily administration for a period of several weeks prior to achieving the desired results.

If you believe your horse has anhidrosis it is important to consult with your veterinarian and regulate your horse’s activities. If you have any questions, feel free to email us at cservice@lifedatalabs.com or telephone at 256-370-7555.

Understanding the Horse’s Digestive System

Horse's Digestion System Blog Photo

Whether it is an animal, plant or other living organism, all living things must have a genetic code and chemical process to maintain life. All living organisms have nutrient requirements that are basically the same at the metabolic level. The difference is how these requirements are absorbed to provide nutrients and energy to live.

For example, plants can manufacture the nutrients and energy they need by staying in one place. They can do this by using the energy from sunlight, along with water, oxygen and nutrients from the soil. In essence, they are self-sufficient.  Unlike animal life, plants do not depend on other living things to survive except for the soil microbiome at their roots.

The Horse vs Other Mammals

Although horses belong to the same animal class as humans and other mammals, they are metabolically smarter than most other mammals. The nutrient requirements between horses and other mammals are the same at the metabolic level; however the horse’s ability to manufacture nutrients is far more advanced.

Humans, for example, must obtain most nutrients they need directly from what they consume. The food and nutrients are delivered to the digestive tract, broken down, and provided to the rest of the body. A horse’s digestion process is much more complex than this. This is in large part due to the hindgut (including cecum and large intestine) of the horse.

The Horse’s Digestion System

The cecum is a large organ within the digestive tract that houses microorganisms. These microorganisms break down the fiber and cellulose the horse consumes and converts the cellulose into additional nutrients and energy that the horse needs to survive. So unlike humans and other monogastric mammals which eat and drink to consume nutrients that are ultimately absorbed, horses not only eat and drink to absorb nutrients but also to feed the microorganism factory within their cecum.

To simplify this process, we can think of the cecum as a “garden” for the horse. This garden enables horses to be mobile in order to consume the nutrients they need. Horses fertilize the garden with the energy and nutrients needed to thrive by providing it with the cellulose of the plants consumed. The garden then produces the “fruits”, or additional nutrients, the horse requires.

The Wild Horse

Before the domestication of horses they were naturally roamers. They would roam, graze, and find the proper nutrition they needed to fully provide for the hindgut microorganisms. Today, we have restricted the horse’s ability to do this by enclosing them in pastures, paddocks, and barns. We have also increased their natural calorie needs by demanding more of them through riding, training, athletics, and work.

The Modern Horse

Modern feeding practices have altered the natural diet of the horse.  Many complete feeds contain excess fats and sugars (molasses), and are also fortified with additional nutrients. This “all-in-one” concept tethers calories and nutrients together; therefore hard keepers and working horses must consume large amounts of the fortified feed to maintain body weight.

This often results in over-supplementation of nutrients, and a diet too rich in fats and carbohydrates. On the other hand, easy keepers are often under-supplemented using this method of feeding. Also note that horses do not have gallbladders. Without a gallbladder the horse is unable to break down and digest the excess fat in many of the modern complete feeds, leading to diarrhea, gas and digestive upset.

Horse Eating

Horses Must Chew

Chewing is instrumental to the horse’s digestion because the grinding serves two purposes, to grind the feed down to small particles and to generate salivation. In a horse, salivation is not initiated from smell or taste, but by the physical action of grinding the teeth. For proper digestion and utilization by the hindgut microbes the feedstuffs must be properly chewed and ground down into fine particles.

For the horse to achieve suitable grinding dental health must be maintained with proper floating. “Over floating” the teeth will inhibit the horse’s ability to grind. The teeth must have rough opposing surfaces for the horse to be capable of proper grinding – if the teeth are too smooth it would be like trying to grind feedstuffs between two pieces of glass.

The horse’s salivation is also important because it coats and moisturizes the food particles in digestive enzymes to kick start the digestive process and help deliver the particles to the GI tract. Most compound and textured feeds that we are using to replace the natural diet of the horse are “pre-chewed”, meaning that the feed has been ground already. The reduced chewing time restricts the amount of salivation, thus interfering with and bypassing an important part of the horse’s digestion.

Proper Care for the “Garden”

If you do not properly care and provide for your garden at home it will not produce healthy fruit, but only weeds and grass. The same goes for your horse. If you do not feed your horse naturally, the garden within your horse will not provide the proper nutrition your horse needs. This can create health issues for your horse.

But, like your garden at home, these weeds can be picked. It is never too late to provide your horse with a natural diet. Remove the fatty foods, the complete feeds, and provide your horse with the diet nature intended it to have. Natural grazing and feeding hay will provide the horse with most of the calories and nutrients the horse needs. Any additional calories needed to maintain body condition should be separated from any additional nutrient intake.

Life Data Forage Balancer

If additional calories are needed, oats, beet pulp, or copra can be fed to meet these increased demands. Proper supplementation with a hay and pasture balancer is also important to replace the nutrients the horse may not be finding in the modern restrained lifestyle.
