Many herbivores chew on bones and antlers that they find of dead animals
out in the wild.  Any skulls, turtles shells, bones left out in the wild
have plenty of chew marks on them from this gnawing, especially from
rodents.  Herbivores also can get calcium from the soil, or limestone. 
There is a photograph documenting a deer eating the chicks of a
ground-nesting bird, presumably for the calcium in their bones!
