Time for soaking hay

[Birker2020]

We have run out of haylage on our yard and I am using the yard hay which is very dusty. I am soaking it but only for about 5 mins, 10 mins max. Does anyone know what research has been done which says what the ideal soaking time is for hay.
Many thanks.

20 - 30 mins for dust thats what the vet told me, longer for lami sufferers
