Description
Return feed cost per dry-matter mass.
Animal feed, milk and scaling terms require explicit dry-matter, energy, component and body-size bases. Empirical coefficients and caller-supplied prices are not universal biological laws. An intake or cost estimate does not select a diet, predict health or establish an appropriate intervention.
Return feed cost per dry-matter mass.
When to use this tool
Use Feed Dry Matter Cost Factor when checking the stated intake, composition, cost or allometric convention.
How to use the tool and how it works
- Enter asFedPricePerMass, dryFraction. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read costPerDryMass. Use the output convention below.
Return feed cost per dry-matter mass. Require asFedPricePerMass >= 0 and dryFraction in (0,1]; costPerDryMass = asFedPricePerMass/dryFraction.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| asFedPricePerMass | As Fed Price Per Mass | Required. Finite number; minimum 0. |
| dryFraction | Dry Fraction | Required. Finite number; maximum 1; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| costPerDryMass | Cost Per Dry Mass | Required. Finite number. |

}Limitations and assumptions
- Price and dry matter are supplied; no actual market quote, feed quality, financial suitability or nutritional recommendation is provided.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use verified animal/feed measurements, the intended validated model and qualified veterinary/nutrition advice for care or feeding decisions.
