How to calculate protein gms in wild game?

I can figure out how much protein in things like beef, pork and chicken (just look at the label, LOL).  But how do you figure out protein on wild game, like deer, squirell, rabbit or wild hog?

For instance, I made gumbo, with brown rice, rabbit , shrimp and okra.  How do I tell how much protein I got? 

I'd go to some place like  caloriecount.about.com 

I use it a lot. All you do is put in the ounces of what ever you're using, the serving size and then hit "analyze"

you can put anything in there.  Also, you can google or yahoo it as a question and see what you get.

I found it on myfitnesspal.com.  Stewed wild rabbit has 50 calories and about 6 gms of protein per ounce.
