Description
Calculate supplied feed-refusal fraction and nominal consumed mass.
Animal records distinguish measurements, count-time exposure, mass fractions, percentages and nominal feed differences. Offered-minus-refused mass does not verify ingestion, and live-weight loss does not identify its cause. Source labels and scalar rates preserve supplied observations without assessing health or suitable care.
Calculate supplied feed-refusal fraction and nominal consumed mass.
When to use this tool
Use Feed Ration Refusal Share Actual when you already have offeredMass, refusedMass and need to calculate supplied feed-refusal fraction and nominal consumed mass.
How to use the tool and how it works
- Enter offeredMass, refusedMass. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read refusalFraction, consumedMass. Use the output convention below.
Require offeredMass>0 and refusedMass in [0,offered]; return refused/offered and offered-refused.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| offeredMass | Offered Mass | Required. Finite number; strictly above 0. |
| refusedMass | Refused Mass | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| refusalFraction | Refusal Fraction | Required. Finite number. |
| consumedMass | offeredMass-refusedMass; nominal disappearance, not verified ingestion or loss separation. | Required. Finite number. |

}Limitations and assumptions
- ConsumedMass is a difference, not verified ingestion; losses and wastage are not separately known. No nutritional adequacy or suitable feeding is assessed.
- 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
Review original animal, feed, weighing and observation records with the complete professional assessment. Check sampling scope, calibration and welfare context before interpreting local fractions or count balances as management or clinical conclusions.
