This is something I've been very interested in, and plant-based nutrition generally. IIRC, a lot of nutrients are absorbed differently from plants and animals (a lot is to do with cell breakdown, GCSE Science tells you that plants have hard-walled cells, animals have soft-walled, as a basic intro). As humans evolved to eat a generally mixed diet, we absorb some things better from animals, some from plants. I would expect (but have no scientific evidence at all, mere speculation) that rabbits could absorb plant-based nutrients better generally, however they might be unable to absorb the 'extra' quantities needed given their propensity to be the sort of animal that's quite fragile, predated and breeds a lot :S
that's very interesting , thanks
