When I have enough available I pile it between my plants so thick it acts as a mulch to smother weeds between my veggies. I have yet to have any burning from it. A bonus is that you will see more worms under it than you ever saw before.
One of the reasons I got into rabbits was for the pellets, my garden just loves them! Straight from the catch bucket to the garden plants. I have great hopes for my garlic this year, it is totally mulched with bunny stuff....
