Calculator guide
What this calculator helps you solve
Convert dry-matter intake to the as-fed quantity required from a feed with a known dry-matter percentage.
Inputs explained
- Dry matter intake — enter the value that applies to your operation or scenario.
- Feed dry matter (%) — enter the value that applies to your operation or scenario.
Formula and methodology
Worked example
A dry-matter intake target of 24 lb from a feed that is 42% dry matter requires about 57.14 lb as-fed.
How to interpret the result
Use this conversion when mixing or feeding ingredients measured as-fed while nutritional targets are expressed on a dry-matter basis.
What to keep in mind
- Use current moisture/dry-matter test values when feeds vary materially over time.
- This calculation converts basis only; it does not establish an appropriate intake target.
Review approach
This calculator uses deterministic arithmetic and performs the calculation locally in your browser. It is designed to combine operational inputs into a decision-oriented result rather than return a one-line conversion.

Frequently asked questions
What decision can this calculator support?
Use this conversion when mixing or feeding ingredients measured as-fed while nutritional targets are expressed on a dry-matter basis.
How is the result calculated?
As-Fed Intake = Dry Matter Intake ÷ (Feed Dry Matter % ÷ 100).
Are the assumptions universal?
No. Operational, regulatory, technical, and industry assumptions vary. Use values that apply to your situation and verify professional or regulatory requirements where relevant.
Does CalculateMeasure store the values I enter?
The calculation runs in your browser and does not require sending the entered calculator values to a server to produce the result.
