Thanks so much
@Marje and Gracie ! Wow they are higher than I thought! I haven't tried the venison yet and Boomer isn't fond of the lamb or the rabbit. Of course he would decide to like the higher carb ones.

If you could give me the formula I could calculate some of the other foods we're trying?
You're welcome!
You'll want the as-feds or DMB values for protein, fat, carbs, ash, fiber, moisture. Sometimes they don't have carbs so you add all the others together and then subtract from 100 to get carbs. When all totaled, they should equal about 100.
Then take the protein, fat, and carbs values, drop the %, and do this:
Multiply protein and carbs each separately, by 3.5
Multiply fats by 8.5
Total the above numbers (add the values for P,C, F together)
For each one, divide the value you got for the specific macronutrient by the total.
For example, let's say the DMB for carbs was 10, protein was 30, and fat was 20:
C: 10 x 3.5 =35
P: 30 x 3.5 = 105
F: 20 x 8.5 = 170
Total: 35+105+170=310
%calories from carbs = 35/310= .11 or 11%
