Metabolic Stability Through Slow Feeding

How extended forage time supports weight, insulin, and digestive balance

Metabolic health in horses is influenced by far more than the type of feed offered. How a horse eats — and how often — plays a critical role in maintaining stable insulin levels, digestive function, and overall wellbeing.

Horses evolved as continuous grazers, producing gastric acid around the clock and relying on steady fibre intake to buffer the stomach, support hindgut fermentation, and regulate endocrine responses. When forage is consumed too quickly or restricted for long periods, metabolic balance is disrupted.

🌾 Why Eating Pattern Matters

When horses consume large volumes of forage quickly, they often experience prolonged periods without feed. These fasting intervals are associated with:

• Increased gastric acidity

• Heightened cortisol (stress hormone)

• Post-feeding insulin spikes

• Disruption of hindgut fermentation

• Increased risk of gastric ulceration

• Behavioural agitation and food-seeking behaviours

Slow feeding addresses these issues by regulating intake rate without reducing total forage allowance.

“Metabolic regulation is achieved through consistency, not restriction.”

🔬 What the Research Shows

Veterinary and nutritional research consistently demonstrates that slow-feeding systems:

• Extend eating time and chewing duration

• Increase saliva production, buffering gastric acid

• Moderate glucose and insulin fluctuations

• Support more stable hindgut microbial populations

• Improve behavioural calmness in metabolically sensitive horses

By slowing the rate of intake, horses experience a more physiologically appropriate feeding rhythm.

🧠 Metabolic Benefits in Practice

✔ Weight management without hunger stress

Slow feeding allows calorie control while reducing the stress associated with restricted diets.

✔ Support for insulin dysregulation

Moderated intake helps prevent sharp post-prandial insulin responses.

✔ Improved digestive comfort

Steady fibre flow supports motility and microbial health.

✔ Reduced risk of secondary complications

Lower stress levels help reduce ulcer risk and behavioural issues commonly seen in metabolically challenged horses.

🌿 How The Ground Grazer Supports Metabolic Health

The Ground Grazer is designed to promote slow, consistent forage consumption in a natural head-down posture, without frustration or feed wastage.

By combining:

• Ground-level feeding

• Controlled intake through a grid system

• Clean, contained forage presentation

The Ground Grazer supports metabolic health while keeping horses calm, occupied, and physiologically balanced.

“Slow feeding is not deprivation — it is therapeutic regulation.”

🐴 Practical Management Considerations

Slow feeding is particularly beneficial for:

• Easy-keeper horses

• Horses with insulin dysregulation

• Horses prone to laminitis

• Horses on restricted grazing

• Performance horses during spells or reduced work

Best results are achieved when slow feeding is combined with appropriate forage selection, routine exercise, and consistent daily management.

Supporting Metabolic Health From the Ground Up

Feeding strategies should support long-term health, not just short-term intake control.
