Dry Matter Basis Calculator
This calculator will help you find out how much protein your cat is really eating & compare it to the amount in other cat foods. As cats are carnivores, it is vital that they are fed a high protein diet to have a long and healthy life.
Dry Matter Basis (DMB or DM) removes the water from the equation. When foods are considered on a dry matter basis, they can be directly compared to one another. In other words, you can compare a canned food with 78% water, to a dry food that contains 11%, or compare two wet foods with different moisture contents. See the example below:-
At first glance, it appears that dry food has more protein than canned food. However, the canned food on a dry matter basis, contains 45% protein, as opposed to the dry food, which contains only 40% protein, when calculated.
The calculator will give you the true content of protein for any of our products once the moisture has been extracted. You will also be able to do some comparisons with commercial wet and dry foods and other raw foods.
Protein = 36%
Moisture = 11%
100% (dry and wet) – 11% (wet) = 89% dry
(36% Protein / 89% dry) x 100 = 40% Protein DMB in dry food
Protein = 10%
Moisture = 78%
100% (dry and wet) – 78% (wet) = 22% dry
(10% Protein / 22% dry) x 100 = 45% Protein DMB in canned food
