When is this year’s hay safe to feed to your horse?

With the recent fine weather, horse owners across the UK have been stocking up on this year’s freshly baled hay — but when is it safe to feed it? Rachel Fraser speaks to Tim Moxon and Annabel Wells, of TM Agri Services Ltd, to find out.

As many faced shortages of hay coming out of spring, owners may be tempted to open fresh bales early in place of using up leftovers from last year. But when is it safe to feed this year’s hay?

Ask seasoned horse owners and the response varies from “straight away” to “after eight weeks”.

In perfect conditions — where the hay has been baled at less than 12% moisture and is very dry — it is safe to feed straight away, but this isn’t often the case, Tim explains: “The main reason for allowing a period of anywhere between two and eight weeks before feeding freshly made hay is to allow for a process called curing to take place.

“This basically allows the sugars and fermentation process to settle to a safe level before feeding so as not to cause colic.

“If the hay has been baled very dry at less than 12% moisture, this shouldn’t be necessary as it shouldn’t need to go through the fermentation process.”

However, guaranteeing that the hay has been baled this dry is tricky and can be a risky strategy to take.

Annabel advises: “Although in theory very dry hay is safe, there is always the risk that there could be damp inside the bale so I would never recommend feeding freshly baled hay straight away.

“Some yards do feed it immediately, but in my opinion it’s always better to be safe than sorry.”

Asking your supplier for their recommendations, erring on the side of caution and waiting longer if in doubt should minimise the risks of feeding new season hay to your horse.
