The bunny devours it whole. Even if you throw it in the grass, it will dig to find it to eat. It may need a little attention not to give it too much because no matter how much you give, it will eat it, so it might not eat enough grass afterward. We put a handful of this and a handful of Oxbow pellets every day for a bunny a little over half a kilo in weight. It disappears all of this in 5 minutes, and it eats the Oxbow pellets slowly throughout the rest of the day. There is also a version for rabbits over 1 year old with slightly lower concentrations of vitamins and nutrients.
