Myth-Busting Without Being a Jerk

The Thrive Feed Myth-Busting Series

Myth-Buster #1

“Dusty Hay Is Normal”

One of the most common things horse owners hear is, “A little dust is just part of hay.”

It is said casually, passed around barns, and often accepted as unavoidable.

But here is the truth.

Dusty hay is not normal, and it is not harmless.

Why People Believe This Myth

Hay is a natural product. It is dried, baled, stored, and handled repeatedly. So it makes sense that people assume dust is simply part of the process.

And many horses appear to tolerate it for years, until they don’t.

That is why the myth persists.

What That Dust Actually Is

What looks like “dust” is rarely just dry grass particles.

It often contains:

• Mould spores

• Fungal fragments

• Bacteria

• Soil particles

• Storage debris

In other words, it is not just mess. It is an airborne respiratory load.

Why Horses Are So Sensitive

Horses were designed to graze fresh forage outdoors with moving air.

Their respiratory system is highly reactive, and repeated exposure to dusty forage can contribute to:

• Chronic coughing

• Nasal discharge

• Reduced stamina

• Inflammatory airway disease

• Equine asthma (heaves)

Some horses show obvious signs quickly. Others develop problems slowly over time.

“My Horse Eats It Fine”

A horse continuing to eat dusty hay does not mean it is safe.

Horses will often keep eating because forage is their primary drive, even when the airways are being irritated.

The damage is often gradual and silent until performance drops or coughing becomes constant.

The Practical Takeaway

Good hay should smell clean, look clean, and produce minimal airborne dust when shaken out.

If a bale creates a visible dust cloud, that is a warning sign, not a normal feature.

And while soaking or steaming may reduce dust in some cases, it does not make compromised hay “safe” if mould is present.

Thrive Feed Principle

At Thrive Feed, we return to fundamentals.

No feeding program can out-perform poor forage quality.

Clean hay is not a luxury, it is the foundation of respiratory health, digestive stability, and long-term soundness.

If you would not want to breathe it, your horse should not have to eat it.
