Horse grass nuts?

Got asked to ask if they are ok for buns :? ive never heard of them

Far as I can tell they're pellets made out of grass for horses. Since they're made from grass they should be safe (though you'd have to check the exact ingredients of each brand). But I wouldnt have thought they'd be a particularly good food to give in large quantities because the rabbits wont wear their teeth down enough on them. Pretty much like standard pellets really in that respect. Far better of sticking with hay or dried grass really.

This is the example I was looking at:
