Reconcile same-cohort feed disappearance and live-weight gain for one completed period on an entered dry-matter basis.
A quick decision brief for this specific tool
Average animals and days for one completed period, as-fed feed offered/refused, representative entered dry-matter percentage, and aligned cohort live-weight gain
As-fed and dry-matter disappearance, animal-days, neutral DM-to-gain and gain-to-DM ratios, and per-animal-day records
Converts measured disappearance to the entered DM basis and divides by aligned recorded gain; it applies no species-independent Excellent/Good/Average/Poor thresholds
Choose your path
Reconcile same-cohort feed disappearance and live-weight gain on an entered dry-matter basis without universal performance grades.
Align animals, days, feed offered/refused and scale-record gain.
Use one completed cohort period and enter each measurement on the labeled basis.
Can reproduce the ratio and spot a mismatched period or refusal record.
Separate as-fed water weight from dry-matter disappearance.
Enter representative feed-analysis DM% and compare only populations, diets and methods that match.
Avoids ranking incompatible records with arbitrary Excellent/Good/Poor thresholds.
Keep diagnosis and ration decisions outside a single ratio.
Review feed loss, sorting, cohort movement/deaths, health, environment, diet and scale calibration with qualified professionals.
Does not change a ration or treatment from generic calculator output alone.
Outputs and checklists are planning aids. Review the linked current authorities and the records, terms, instructions, and requirements that apply to your exact situation before a consequential decision.

Average animals, observation days, feed offered/refused, dry-matter analysis, and live-weight gain must describe the same completed cohort period.
As-fed disappearance equals offered minus refused feed. Multiplying by the entered dry-matter percentage removes water weight before dividing by aligned live-weight gain.
The tool reports DM per pound gain, gain per pound DM, and per-animal-day records without Excellent/Good/Average/Poor grades, ration advice, diagnosis, or future-performance claims.
Updated: August 2026
Reconcile measured feed offered/refused and scale-record live-weight gain for one completed group and period.
Convert as-fed disappearance with representative analysis before comparing truly like diets, populations, stages, and methods.
Expose zero or inconsistent disappearance records and document movements, deaths, feed loss, sorting, shrink, and scale limitations separately.
Enter measured offered and refused feed on the same as-fed basis plus a representative dry-matter percentage for the period.
Align cohort, dates, production stage, diet, measurements, transfers/deaths and scale basis. Interpret differences with qualified nutrition and veterinary guidance.
Turn one completed cohort record into transparent as-fed disappearance, dry-matter disappearance, animal-days, and neutral feed/gain ratios. The worksheet deliberately avoids species-independent performance labels and ration or health recommendations.
