has anyone heard of freeze dried grass

[michellemuffin]

I brought a hugh bale in Jollyes last week and it is actual grass still green but hard, my pigs enjoyed it and I use it as an added treat rather then bedding as some might do, they eat it but i would'nt say they are over the top about it,
my hay man a farmer called Mick said its quite possibly been imported from France cant see on sticker if it is, has anyone else used it?

have heard of it and seen it but I don't get any.. It has less nutritional value than fresh grass, and my lot prefer the fresh stuff too.
