If you have loads you can apparently dry them like hay for bedding.
We tried this and do not recommend it. It makes something softer to lie on than cement, but is not at all absorbent, and the stock won't eat it when freshly spread either. So no use for fodder nor for keeping them dry. And doesn't compost like hay or straw either (presumeably partly because it isn't absorbent), so if you deep litter it gets quite horrible.
When we have a 'reshy bale' of silage, BH tries to use it outside, so that the cattle pick out the grassy stuff that they like, and leave the reshy parts that they don't, which then spread and blow around, rather than have the rejected fodder indoors, needing scraping up and putting on the muck heap.
We did think about using small bale reshes for shelter for lambs, but they don't hang together well so the strings come off, don't weigh enough so blow about - altogether, we couldn't find a way of using them. Except on muddy ground - precisely because reshes are not absorbent and don't rot properly, I've used them in front of the pig ark to keep it a little less knee-deep. They might also be useful for scattering in chicken runs for the same purpose.
