Today, we are focusing on how much a horse should eat.

Horses should not eat continuously, but determining the right amount of food and finding the right balance between enough and too much can be complicated, particularly for horses with insulin resistance or metabolic issues.

Metabolic and Insulin-Resistant Horses

Feeding horses with metabolic issues and insulin-resistance the correct amount can often be the missing piece once their exercise and nutrition are optimized. Some horses can self-regulate easily, while others need careful management to avoid overeating.

Feeding the Right Amount of Hay

A widely accepted guideline is to feed horses between 1.5% and 3% of their body weight in hay per day. That is not a hard and fast rule, however, as hard keepers and some thoroughbreds may require more, while easy keepers and metabolic horses may need less. The key is to adjust the quantity according to the individual needs of each horse.

Finding the Right Balance 

Horses can usually cope with three to four hours without food, but extended gaps should be avoided, especially within a 12-hour window. Feeding them too much can increase weight gain and metabolic issues, while over restricting can slow their metabolic rate, raise their stress levels, compromise their immunity, delay healing, and increase the risk of ulcers. 

Factors That Matter

The needs of horses vary according to their breed, body condition, health status, and even past experiences with food scarcity or starvation. Herd dynamics can also influence intake, as dominant horses often consume more than their share, leaving others with less. Noticing which horse controls access to the hay and how it interacts with its herd mates can reveal any hidden imbalances in feeding.

Managing Intake 

Slowing their eating tends to be more effective than feeding horses less. Using small-hole slow-feed nets, providing smaller portions often, and placing hay in different locations can help owners control their food intake. Owners should also encourage their horses to move by using track systems, ponying them, or taking short walks, as that supports their metabolism, increases satiety, and reduces the urge to graze constantly. The increased muscle mass will also increase the metabolic rate of a horse, helping to manage its weight more effectively.

Special Considerations 

Horses with insulin resistance or other metabolic issues tend to become hungry more often, as blood sugar fluctuations affect their satiety hormones. Owners should provide those horses with a low-glycemic forage and high-quality nutrition. They should also ensure they exercise regularly, using track systems, ponying them, or taking short walks to support their metabolism, increase satiety, and reduce the urge to graze constantly. As their nutrition improves, those horses may even naturally reduce their eating to play and interact with other horses.

Practical Feeding Adjustments

When horses have free access to food, it can be challenging to know exactly how much they eat, so observing their behavior is often the best way to gauge their intake. It is also essential to consider pasture consumption, especially when the grass is abundant, to prevent calorie overload. Proper storage and presentation of hay will reduce waste, which sometimes means holding off on topping up until the horse has finished eating.

Planning Strategically 

Horses train their humans to feed them on cue, so when owners become strategic about their feeding times, it helps to maintain a healthy balance between satisfaction and overfeeding.

This week, we are focusing on dosing.

In this episode, I explain the concept of the minimum effective dose, which is the smallest dosage required for the body to respond to or benefit from. The same principle applies to horses when adjusting their nutrition or adding supplements. The aim is to provide just enough to see a positive response, without going so far that it causes unwanted or harmful effects.

Dosing Principles 

In pharmacology, the ideal dosing range lies between the minimum effective dose and the maximum tolerated dose. That principle also applies to nutritional supplementation in horses, where exceeding the minimum effective dose could lead to side effects or adverse reactions. The goal is always to use the smallest amount that elicits a benefit, minimizing waste and risk.

Why Less Is More

Once a supplement starts to work, increasing it will not necessarily improve the results. It will likely reduce the effectiveness and strain the body. So, always start with just enough to be effective.

Individual Tolerance and Sensitivity

Every horse responds differently to supplements. Factors like breed, health history, and immune strength all play a role. One horse may tolerate pasture or a supplement easily, while another may react badly to the same thing. Sensitivity varies widely, so dosing should be based on the individual horse rather than generalized standards.

Understanding the Modern Horse

Today, horses are often nutrient-deficient due to poor food quality, high toxicity levels, and chronic stress. Those factors increase sensitivity and reduce nutrient absorption, leading to horses with leaky gut, immune disorders, or genetic diseases that require a more individualized approach to their supplementation.

Start Low 

Many people tend to overdo supplementation, thinking more is better. That mindset could be harmful for sensitive animals like horses. When starting with a low dosage, you allow room to adjust upward if necessary and can avoid overloading the body. High doses can cause intolerance and side effects that could be mistaken for a problem with the supplement itself.

Special Considerations 

The form and bioavailability of nutrients are the keys to determining whether or not a horse can absorb and benefit from them. For horses with inflammation, metabolic issues, or digestive stress, gentle and minimal intervention is always better. By avoiding multivitamins and using single, targeted nutrients instead, horse owners can support more precise and effective recovery. 

Form Matters

Nutrient forms differ in their bioavailability. For example, magnesium oxide is less bioavailable than magnesium citrate or magnesium glycinate. When absorption is poor, you may need higher doses to see results, which can push the dose closer to the maximum tolerated limit without any real benefit. Choosing well-absorbed, high-quality forms helps ensure the horse benefits without adding stress to the body.  

Watch for Absorption Issues

Stress and chronic health conditions can impair nutrient absorption. Even the best supplement will not help if the horse cannot digest or utilize it. Bloodwork is helpful, but if levels do not improve with supplementation, the issue may be poor absorption rather than insufficient dosing.

Over-Supplementing and Nutrient Competition

Supplements with too many ingredients can cause nutrients to compete for absorption, reducing their effectiveness. For example, copper and zinc interfere with each other when given together. Complex formulas can overwhelm the body, adding to its load. In many cases, simplifying the diet is more effective than increasing supplementation.

Reset and Rebuild

In cases of toxicity or poor liver function, the best course may be to remove all supplements, leaving the horse on only hay and water. That helps the body reset, reduces inflammation, and reveals whether or not a supplement is causing harm. Recovery should always begin with the basics. Only add nutrients and supplements once the horse can handle them.

Quotes:

"Always start low with dosage."

"Over-supplementing creates more problems than it solves."

"Watch the horse, not the label."

"Use high-quality nutrients with proven bioavailability.”

"If you are not seeing improvement, pull back and reassess."

"Sometimes the best thing to do is nothing but hay and water."

"Do not assume more is better."

"Form matters more than quantity."

We are exploring glucosamine today.

About a decade ago, glucosamine was marketed and sold as a joint supplement for horses. It is still available for joint support in dogs and humans, but seldom as a supplement for horses. 

In this episode, I discuss my experience with glucosamine, sharing its origin and clarifying some of the holistic principles it breaks.

Nutrients vs. Nutraceuticals

Nutrients are the vitamins, minerals, and essential fatty acids that are essential for life and must come from food. Glucosamine is a nutraceutical, a non-essential compound found naturally in cartilage that can help manage joint inflammation. It is not a dietary requirement, and it does not address deficiencies.

Doubt Around Glucosamine

Glucosamine was once widely used in equine joint supplements, often combined with MSM or chondroitin. However, many horse owners and practitioners saw no real benefits. Its popularity was due to marketing and general concerns about joint health and mobility in horses.

Inflammation 

Supplements alone cannot cure joint inflammation. Often, underlying factors (stress, poor diet, and excessive sugar) play a role. If those issues go unaddressed, even the best supplements will be inneffective.

Insulin-Resistant Horses

Glucosamine is an amino sugar that contains a glucose molecule, which raises red flags for insulin-resistant horses or those with a sluggish, congested liver. Those horses are already prone to inflammation and joint pain, and adding glucosamine may further burden their liver’s ability to metabolize.

Long-Term Supplementation

Long-term use of glucosamine without addressing nutrient deficiencies may do more harm than good. The liver metabolizes everything that enters the body, so long-term supplementation could overburden it, especially if the supplement is unnecessary or of low quality.

Source Matters

Most glucosamine gets sourced from shellfish, which violates holistic principles for horses, as they are strict herbivores. Using animal-based ingredients for horses is not considered species-appropriate and should always be avoided unless the supplement is truly effective.

Glucosamine Forms and Sulfur Sensitivity

Glucosamine comes in different forms- either glucosamine sulfate or glucosamine HCl. As the sulfate version can cause sensitivities, like hives or respiratory issues, glucosamine HCl may be a safer option for horses with sulfur sensitivity.

Evaluating Supplement Effectiveness

To assess whether a supplement is truly helping, always consider whether mobility is improving and inflammation is decreasing. If you cannot see or measure any benefit, reconsider its use. Addressing nutrient deficiencies will likely lead to more effective and lasting results.

Study Limitations 

Scientific studies on glucosamine are inconclusive and often based on other species (like rats, mice, or humans), so they may not reflect the realities of insulin-resistant or metabolically compromised horses. Ultimately, the individual history and response of the horse should guide your decisions.

Final Considerations

Although glucosamine is not inherently harmful, its long-term use should be questioned, especially for horses with insulin resistance. Glucosamine is not an essential nutrient, and it may place unnecessary strain on the body. 

Always prioritize foundational nutrition before turning to nutraceuticals.
