It might be a good idea to observe what the rabbits in your chosen hunting area are eating.
I'm harvesting squirrels in an area with berries and nuts instead of just acorns and I believe this is showing up in the taste. I'm getting some very tasty squirrels! I've also seen comments on the various boards about this animal and that animal and what they are eating and how they taste.
Good eating & good luck!
