Dry Matter Calculator

Convert an as-fed nutrient to a dry-matter basis.

Nutrient (dry-matter basis) (%) 40

Dry matter (%) 25

Formula: DM basis = as-fed % ÷ (1 − moisture/100)

Step-by-step with your numbers:

1. Values used:

2. Nutrient (as fed) = 10 %

3. Moisture = 75 %

5. Nutrient (dry-matter basis) = 40%

6. Dry matter = 25%

Did we solve your problem today?

Compare feeds fairly by removing the effect of water content.

The math behind it

dry matter = 100 − moisture. Nutrient on a dry-matter basis = as-fed nutrient ÷ (dry matter ÷ 100).

10% protein at 75% moisture → 40% on a DM basis.

Why convert?

Wet and dry feeds can't be compared as-fed because water dilutes the numbers.
