Soaking versus steaming
Soaking or steaming? - the data speaks for itself
Even the best hay and haylage contains many respirable particles such as bacteria, mold, yeast and fungal spores.
These unwanted particles, which can cause mild to severe respiratory and digestive issues, wont be eliminated by soaking, watering, rinsing or wetting the hay.
There are also a number of other downsides to soaking your hay - check out the chart.

5 Reasons to stop soaking by Dr Moore-Colyer
1. Soaking increases bacteria content by 150%
2. Soaking reduces palatability
3. Soaking compromises hygiene
4. Soaking doesn't effectively prevent asthma
5. Soaking is hard on the environment
Haygain Steamers - what do they do differently?
Haygain's patented technology is the only scientifically proven way to eliminate all the unwanted particles that can't be removed through soaking.
Steaming reduces bacteria and mold whereas soaking increase this dramatically.
Steaming has 6 main benefits - respiratory health, digestive health, palatability, performance and skin conditions.
What about home made steamers?
With a homemade steamer the steam is going from the outside-in and most of the heat will be lost through the non-insulated walls (especially during winter). Without fully penetrating the hay and steaming it at a temperature of at least 194ºF for a minimum of 10 minutes, the hay will become an incubator of pathogenic bacteria, yeast, mold and fungi.
Haygain's patented and proven manifold spike system was designed to inject steam from the inside-out, and ensures that all of the hay is steamed evenly. Its insulated hay chest is attached to a purpose-built steam generator that steams the hay for 60 minutes at temperatures that reach 212ºF. This effectively eliminates harmful mold, fungal spores, bacteria and dust mites.
