Here is the guaranteed analysis of the Evo Chicken canned:
Crude Protein (min) 9 %
Crude Fat (min) 10 %
Crude Fiber (max) 1 %
Moisture (max) 78 %
Carbohydrates NFE (max) 0.46 %
Vitamin E (min) 100 IU/kg
Calorie Content:
1,349.8 kcal/kg
38 kcal/oz
The moisture is 78%, so the recipracol of the moisture is 22.
The fat divided by the recipracol of the moisture (10 divided by 22) equals .45. Move the decimal point two places to the right and you have 45% fat.
You can do this for kibble also but the results aren't much different from what is on the bag. |
Crystal you AMAZE me! how do you know so much??
