Is wetting hay good for horses?

Many studies have shown soaking hay can reduce respirable particle concentration by at least 88%. Soaking can also reduce the amount of mold present. Nutrient content Some horse owners soak their hay to reduce the amount of sugars, or nonstructural carbohydrates (NSC), in the forage.

How wet is too wet for hay?

The first thing to keep in mind when dealing with wet hay is that moisture can easily lead to combustion. Twenty percent moisture is about the highest level that bales should reach. Above this, microbes begin to break down plant matter and mold growth occurs.

Round hay bales should not get wet, as the moisture of the average bale should not exceed 20%. If it does, then mould can develop in the bale, preventing you from selling the hay.

Is hay ruined if rained on?

Hay that has been cut and then rained on can lose quality in four ways. These include: 1) leaching of soluble carbohydrates, vitamins and minerals, 2) increased and prolonged plant respiration, 3) leaf shattering, and 4) microbial breakdown of plant tissue.

What happens if you soak hay too long?

Don’t soak the hay longer or you’ll risk leaching beneficial nutrients. Soaking hay to remove sugars that can exacerbate metabolic conditions such as insulin resistance takes more time.

What are the signs of poisoning in a horse?

• Abdominal pain.
• Constipation.
• Diarrhoea.
• Straining.

Can horses get botulism from hay?

Figure 1: Horses eating from round-baled hay are more susceptible to developing botulism, especially if the hay was not baled appropriately or if a dead animal was baled together with the hay. Botulism is a deadly disease caused by the toxins produced by the bacterium Clostridium botulinum.

How can you tell if hay is moldy or dusty?

Do horses like soaked hay?

Soaking hay for horses can be invaluable when feeding a hay that is a little dusty as a result of soil contamination or where it was stored in the barn. Horses that have allergies and are sensitive to the natural dust and particles in hay can benefit significantly from wetting or soaking hay.

How long can you leave soaked hay?

In warmer conditions, soaking hay for more than two hours is also likely to result in the hay starting to ferment and this is not desirable for then feeding to horses. Studies have shown that soaking for longer periods such as 9 hours, also increased the microbial contamination in the hay.

How long does it take wet hay to dry?

Why can’t you put wet hay in a barn?

Actually, wet hay is more likely to lead to spontaneous combustion than dry hay. If wet hay with more than 22% moisture is stored in a barn or stacked then the risk of spontaneous combustion is increased. Further, the wet hay loses in forage quality.
