Benefits of hay steaming

For your horse, you and the environment

For your horse

A recent study showed that 88% of horses examined suffered from Inflammatory Airway Disease (IAD). One of the main causes of IAD is respirable dust and a major source of this is hay. IAD can limit an athletic horse’s performance. 

Haygain hay steamers are the only scientifically proven method to dramatically reduce respirable dust in hay and kill mould, fungal spores and bacteria that can cause IAD. The above study found that steaming hay with a Haygain hay steamer reduced the risk of your horse developing IAD by 65%. Read the research.

For you

Studies highlight the need to review horse care activities and implement dust-reducing stable management regimes to reduce the incidence of respiratory disorders in people working with horses. 

25% of people working with horses have a diagnosed respiratory condition such as asthma, not to mention all the hay fever suffers. 

Steamed hay effectively reduces these incidences.

For the environment

Steaming hay drastically reduces water consumption. Filling a container for soaking hay typically uses 50 - 250 litres. The sheer volume of water used has an impact not just on water bills, but also on the environment. 

Post-soak water is contaminated with bacteria, mould, WSC, proteins and minerals which leach out of the hay, making it an environmental pollutant which must not be disposed of in storm drains. Haygain steamers only use about 4 ½ litres of water per cycle and produce no environmental pollutants.

For your wallet

An epidemiological study found respiratory problems in racehorses to be the second highest reason for lost training days. 

A dusty stable environment can have financial implications; not just in lost training days but vet bills.
