Better feed.
Clearer calculations.

Choose your animal and production stage, enter your nutrient targets and local ingredients, and calculate the lowest-cost blend that meets your stated constraints.

RationWise calculates ingredient cost and nutrient balance from your data. Breed selection does not automatically supply nutrient requirements. Results need qualified nutrition and feed-safety review before animal feeding or manufacturing.
FEED FORMULATION

Create a least-cost feed formula

Follow the four steps below. All nutrient targets and ingredient analyses must come from sources appropriate to your animal and production stage.

STEP 01 Set the animal, breed and batch before entering nutritional data.

Your animals & feed batch

Currency is a label only; there is no foreign exchange conversion. Breed, age, weight and production details are recorded for review but DO NOT automatically adjust numeric requirements. Changing the stage clears current nutrient and ingredient inputs. Eleven animal groups (cattle, buffalo, sheep, goats, chickens, turkeys, ducks, geese, quail, fish and pigs). Targets start blank, except where a user elects to copy three explicitly labeled historical poultry-reference preview values. The stage fields are not complete feeding specifications.

Advanced scientific toolsLaboratory import, reference grids, scientific review and additional nutrient models

Import laboratory analysis

Use a long-format lab CSV with one row per ingredient × analyte. Report dry_matter first as percent of as-fed mass, then other analytes with their explicit basis (% / g/kg / mg/kg, or MJ/kg / kcal/kg for energy). Each row needs a sample date, lab/method, evidence ID and use-rights category. Conversions are checked and original values are retained in the editable JSON record. No published database values are bundled.

A laboratory import replaces the ingredient table and never fills unreported nutrients with zero. You must still supply your own local prices and inclusion bounds.

Scientific and safety checklist

Each ingredient has a new hazard/suitability screening field and document identifier in its table row. Mark a pass only if you have supporting test results and local species-specific checks. This preflight identifies known gaps but does not certify animal nutrition or regulatory compliance. Calculations remain usable while feeding/manufacturing release stays separate.

No scientific readiness check run yet.

Reference-based nutrient target estimator

Reference grids contain no bundled numerical anchors. Generate nutrient targets by interpolating documented, species/stage-specific reference points. Enter measurements for the animal, import a licensed reference grid, or create/edit your own. This interpolator never extrapolates beyond measured reference anchors; it does not predict feed intake or replace independent nutritional review.

The stage template represents only eight selected constraints. Interpolated concentrations are not a complete diet requirement model; true adequacy also needs intake, micronutrients, digestibility, hazards, regulations and independent review. Claims entered in a local browser are not verified authentication.

Historical poultry reference preview

Try selected values from a 2020 USDA NRCS poultry technical note, itself based on older NRC 1994 recommendations. The historical reference is included to demonstrate transparent sourcing, conversion and gap analysis, not as a modern commercial diet prescription. Commercial rights for the underlying adapted NRC data have not been cleared.

Only broiler starter/grower/finisher and laying-hen historical examples are preloaded. All other animal/stage requirements remain blank rather than inheriting unrelated species numbers. Missing energy, digestible amino acids, micronutrients and real feed-safety checks must be addressed by a qualified professional. Source values apply to a 90% DM diet and are converted to a DM basis before comparison.

Nutrient profile review records

Create an editable review dossier for each animal and stage. Audit the eight nutrient targets for exact stage match, units, documentary rights, reviewer claims, and outstanding feed-safety checks. This is not a professional review or approval service: no credentials, signatures, permissions or completeness are authenticated here.

Additional scientific and release-evidence checks

A completed audit means only that the entered evidence fields pass structural checks. The 8 selected constraints are not a complete nutrient, safety or intake model. Data is handled locally in your browser. For regulatory use, implement server-side identity, signature, independent review, audit and licensing verification.

PROFILE WORKFLOW · NOT AUTOMATIC FEEDING ADVICE
!
Breed-specific requirements are not yet preloaded. These details help select and assess scientific reference profiles. Breed selection alone does not generate nutritional targets. Local profile exports remain on your device; Secure accounts and Stripe subscriptions are configurable in the account workbench; until connected by the owner, local JSON export remains available.

01 · Location and herd / flock / stock

02 · Actual animal and production measurements

Use only applicable fields. No default body weight, growth, milk yield, or feed intake is invented.

Optional: check the scope of a scientific requirement source

This only checks exact animal-stage, breed and country metadata. It does not authenticate a publication, reviewer, target values, or usage rights.

CALCULATIONS ENABLED · INDEPENDENT NUTRITION REVIEW REQUIRED
!
Numerical requirements are intentionally blank. Enter nutrient constraints only from sources you have rights to use, and ingredient composition from supported laboratory analyses. Calculations are not feeding approval. Other 34 stage templates remain in the original calculator below.

01 · Species, production stage and market

02 · Evidence, commercial rights and external review

03 · Enter nutrient targets, independently established

Targets are stored on a dry-matter basis (unit per kg DM), except when deliberately set to as-fed in imported JSON. Enter an exact document locator for each constraint. Blank = not optimized. Values are never autofilled.

04 · Ingredient analyses, local prices and inclusion limits

All ingredient analytes are measured per kg dry matter; prices are per kg as-fed in your selected currency. Never enter unknown laboratory values as zero. A failed safety screen blocks optimization.

Enter real input values to calculate.

The audit documents gaps; it does not check reviewer credentials, rights authenticity, contamination risks, premix potency, mixing quality, complete animal requirements, or regional feed law. Numerical results are never automatically certified as feeding-ready.

PAYMENT ACTIVATION REQUIRES VERIFIED MERCHANT SETUP
!
No nutritional certification is included with any plan. International payment availability, taxes and local feed requirements depend on the user's country. Do not enter payment cards on this site: all payment entry takes place on Stripe-hosted pages. Pricing below is proposed, and checkout appears only after configuration.
