Hay Intake Percent Bodyweight Calculator
Actual horse actual hay mass/bodymass percent with verified dry-matter conversion. Not a recommended ration, grain/forage safety, complete nutrition or clinical assessment.
Description
Hay mass on an as-fed basis and on a dry-matter basis describes different quantities.
Hay mass on an as-fed basis and on a dry-matter basis describes different quantities.1
Body-mass percentages allow a documented intake comparison after the dry-matter fraction is established.
When to use Hay Intake Percent Bodyweight Calculator
Use this tool to calculate or review the supplied observations under the stated rules. Establish the animal, measurement protocol, units and independently applicable veterinary prescription or reference.
How to use Hay Intake Percent Bodyweight Calculator and understand its results
- Establish the animal, measurement protocol, units and independently applicable veterinary prescription or reference.
- Enter actualDailyFeedAsFedKg, independentlyMeasuredHorseMassKg, verifiedDryMatterFraction, using the field meanings and rules below, then run the tool.
- Read result.observedAsFedPercentBodyMassPerDay, result.observedDryMatterPercentBodyMassPerDay. Use the units and subtraction order below to interpret each value; retain negative differences where returned.
- Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| actualDailyFeedAsFedKg | Actual daily feed as fed kg | number | Required |
| independentlyMeasuredHorseMassKg | Independently measured horse mass kg | number | Required |
| verifiedDryMatterFraction | Verified dry matter fraction | number | Required |
Require nonnegative as-fed mass in kilograms, positive horse body mass in kilograms and a dry-matter fraction in [0,1]. Express the as-fed mass and its dry-matter portion as percentages of body mass. No minimum, maximum or ration prescription is imposed.
asFedPercent=100×asFedKg/bodyMassKg; dryMatterPercent=100×asFedKg×dryMatterFraction/bodyMassKg Use the matching field units and the exact boundary, ordering and reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Qualified observation, conditional calculation or reference | object |
| result.observedAsFedPercentBodyMassPerDay | Recorded as-fed mass as a percent of horse body mass for the declared daily record. | number |
| result.observedDryMatterPercentBodyMassPerDay | Recorded as-fed mass times dry-matter fraction as a percent of body mass. | number |

}Limitations and assumptions
The patient context, observations and applicability of any reference or prescription must be independently established. This result supplies no diagnosis, default dose, treatment selection or assessment of clinical suitability.
Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Extremely large composite outputs are rejected.
Alternative or Complementary methods
For a related step, use Daily Poultry Feed Consumption Calculator: Flock feed accounting separates supplied feed from remaining feed and independently measured spills. For a complementary comparison, use Horse Feed Ratio Bodyweight Calculator: As-fed ration mass includes its moisture, while dry-matter mass removes the measured water fraction.
