Subject: Can humans digest bone from livestock, poultry?

I know digesting fish bone is easily done, but I can't seem to find any info 
regarding what happens if bones from say, deer, cow, chicken, turkey, etc are 
ingested. I'm curious because I find deer antlers (bone) in the woods & field 
by our house always chewn-on and our dog just eats bone from leftover steaks. I 
wonder why animals can do this, yet humans don't. Is it because there are 
easier ways for humans to get the nutrients that bones provide, or because we 
simply can't digest it. In this case, will it simply linger in our stomach 
for...ever?
