Soaking your Hay

“Before I was introduced to Haygain, I was soaking hay for Brentina to make sure that it was more palatable and dust free. Then I found Haygain and not just Brentina but every horse in our barn is so happy. Now after our horses are fed the only sound you hear are the horses chewing. I no longer hear sneezing or coughing due to dust or mold spores. Once you have fed Haygain you will never go back!”Debbie McDonald, Team USA US Equestrian Dressage Team Chef d’Equipe Olympic medallist, two World Cup medals, two Pan American Games medals, World Champion


“We had been soaking our hay and that was a real nightmare. They love not having to do that anymore and the horses are happy and healthy.”Liz Halliday-Sharp, Team USA Ambition to become first woman to win the 24 Hours of Le Mans race and ride for Team USA

Some people believe that by watering, wetting, rinsing or soaking their hay they are removing the airborne dust and solving the problem of irritation and respiratory inflammation. Unfortunately, soaking comes with a number of downsides.

Problems with Soaking

It has been shown that if you spray hay you can reduce airborne respirable dust by 43%, but if you completely submerse hay for 10 minutes you can increase this to 90%.

But it creates problems:

  • Soaking only dampens down the respirable particles and only by 90%; and the bacteria, mold and fungal spores are ingested and can elicit an inflammatory response

  • Soaking increases the bacterial content - a 10 minute soak increases bacteria by 150%

  • Soaking reduces the palatability

  • Significant levels of nutrients are lost

  • Produces a post-soak liquid that is 9x more polluting than raw sewage

  • Uses 60-100 litres of water

  • Is messy and difficult to handle

The Solution? Haygain Hay Steamers

  • Reduce respirable particles by 98%

  • Dramatically reduce bacteria and mold content

  • Improve palatability

  • Retain nutrients

  • No effluent

  • Only uses 4 litres of water

  • Clean and easy to use

“The difference between soaking and steaming is chalk and cheese... soaking does a lot of negative things to your hay"
