Environmental Benefits of Using A Hay Steamer for Horses

hay steamer for horses

Horses are exceptionally sensitive to dust and mold particles found in their bedding and hay. Consistent exposure can cause horses to develop respiratory problems and even skin allergies. As a horse owner, you should do all that you can to ensure your horses are happy and healthy. Using a hay steamer is one way you can help reduce the risk of respiratory problems in your horses.

But what is hay steaming? How does it work and what are the environmental benefits?

What is Hay Steaming?

Hay steaming is a technique used to reduce airborne dust and mold that can cause respiratory issues in horses (and humans). The process is a simple one:

  • A steam generator creates steam
  • The steam travels through a hose connected to a closed container that holds the hay

With the right setup, the hay can reach over 212°F (100°C), a temperature that has been proven to kill mold, bacteria, and fungal spores. When successful, the process can reduce airborne dust by up to 98%.

Hay steaming is already popular in Europe, and now, it’s gaining traction in the United States. But it’s not the only method you can use to reduce airborne dust and mold. Soaking is another way to accomplish the same goal.

Steaming vs Soaking Hay

Steaming and soaking can both reduce airborne dust and mold in hay. Long before steamers were commercially available, horse owners would soak hay for anywhere from 10 minutes to 12 hours before draining.

Soaking has also been shown to reduce airborne dust by a significant amount – up to 90%. Dampening the hay makes dust less likely to be inhaled.

While cost-effective and simple, soaking hay does have its drawbacks.

  • It’s not as effective as steaming at reducing airborne dust particles.
  • Soaking can increase bacteria levels by up to fivefold.
  • Soaking reduces the nutritional value of the hay, as protein, minerals and carbohydrates leach out into the water.
  • The post-soak liquid is considered a pollutant. In fact, lengthy soaks can produce a liquid that’s nine times more polluting than sewage.

Generally, horses find soaked hay less palatable compared to their steamed or dry counterparts.

While both methods can achieve similar outcomes, steaming is the preferred technique for reducing airborne mold and dust in hay. Apart from being overall better for the horse, steamed hay is better for the environment. The post-soak liquid can’t be dumped down drains and must be disposed of responsibly.

What are the Benefits of Using a Hay Steamer?

Steamed hay offers a number of benefits for horses and the environment.

Less Water Consumption

One big environmental benefit of steaming hay is that it uses less water than soaking. It takes 50-250 liters of water to fill a container for hay soaking.

Along with increasing water bills, soaking hay regularly can take a toll on the environment.

Respiratory and Skin Benefits

As you already know, steaming hay has respiratory benefits for horses. It reduces airborne mold and dust by over 90%.

Steaming can also help reduce bacterial contaminants that cause skin allergies.

Improved Digestive Health and Hydration

Untreated hay can contain microbial contaminants that cause digestive issues in horses. These contaminants disrupt the horse’s natural microbial balance, leading to dysbiosis and conditions like colic.

Steaming raises the hay’s temperature high enough to kill bacteria that causes digestive issues.

Along with supporting healthy digestion, steaming can also help horses stay hydrated. Untreated hay contains just 10-20% water. Steaming adds moisture to support hydration and makes it easier for horses to chew.

Preserves Nutrients

One big disadvantage of soaking hay is that the water-soluble protein, carbohydrates and minerals leach out into the water. The hay then becomes less nutrient-dense.

Research has shown that mineral and protein levels were unaltered from steaming. As a result, horses enjoy more nutrient-rich hay that’s more palatable and enticing – even for picky eaters.
