Feed mill planning tool

Ingredient Lot Comparison Calculator — After Quality Deductions

Compare two offered lots of a feed ingredient after your contract's protein and moisture deductions and rejection limits: net price, cost per dry tonne and per protein point.

How do you compare two ingredient lots with different quality?

Apply your contract's own deductions to each lot's analysis — a discount per protein point below spec and per moisture point above spec — and drop any lot that breaks a rejection limit such as maximum moisture or aflatoxin. Then compare the net price per tonne of dry matter, not the offered price: a cheaper lot with more water or less protein can cost more for what it actually delivers.

Deduction breakdown per tonne

Moisture deduction	USD 0.00	USD 5.00
Cost per protein point	USD 9.78	USD 9.50

What this tool calculates

Applies your protein and moisture deduction rates to each lot's certificate of analysis.
Flags lots that exceed your moisture or aflatoxin rejection limits instead of pricing them.
Compares net price, cost per dry-matter tonne and cost per protein point.

What it cannot do

It holds no prices, market deduction scales or regulatory limits — every term is from your own contract.
It does not judge nutritional value beyond protein and moisture (amino acids, energy, fibre, other contaminants).
It does not replace an independent sample analysis or a lab certificate.

Who this is for

Feed mills choosing between two offered lots of the same ingredient
Ingredient buyers checking whether a discount covers a quality shortfall
Procurement teams preparing a specification for an RFQ

Methodology

Protein deduction = max(0, spec protein − lot protein) × rate per point. Moisture deduction = max(0, lot moisture − spec moisture) × rate per point. Net price = offered price − deductions. Cost per dry tonne = net price ÷ (1 − moisture %). Cost per protein point = net price ÷ protein %. A lot above either rejection limit is excluded from the comparison.

Assumptions

Prices are delivered (landed) per tonne on the same basis for both lots — use the landed cost calculator first if offers are FOB.
Deductions are linear per percentage point, as in many trade contracts; tiered or fractional scales need the contract table.
Default values are illustrative example inputs, not market prices, standard deduction scales or legal limits.

How FeedMatch builds and reviews its calculators

Worked example — illustrative inputs

Inputs

Spec: 46% protein min, 12.5% moisture max; deductions 8 USD per protein point and 5 USD per moisture point
Lot A: 455 USD/t, 46.5% protein, 12.0% moisture · Lot B: 440 USD/t, 44.8% protein, 13.5% moisture

Outputs

Lot A net 455 USD/t, about 517 USD per dry tonne
Lot B net about 425 USD/t after 15 USD of deductions, about 492 USD per dry tonne

How to read it. With these example terms Lot B stays cheaper per dry tonne even after deductions, but it delivers less protein; check the cost per protein point and your formulation before choosing. The inputs are illustrations only.

Limitations

Indicative comparison, not a quality ruling. Final settlement follows your contract, sampling method and the agreed laboratory.
Feed contaminant limits differ by country and species; confirm the applicable limit with your regulator or quality team.

All figures are indicative planning estimates for budgeting and supplier discussion. They are not quotations, guarantees or professional engineering, nutritional, legal or financial advice. Have results reviewed by the responsible professionals before you commit capital.

Sources and data

Inputs: every number comes from what you enter. Default values are illustrative only, not market data.
Method: the arithmetic described under "Methodology" above, applied to your inputs. No external price, nutrient or supplier database is used.

What can change the result?

· Animal numbers and cycle length
· Intake curve and stage split
· Mortality, waste and shrinkage allowance
· Feed price per tonne
· Season, climate and management effects

AI agents may use FeedMatch calculators to structure preliminary feed requirements and RFQs. Nutrition, process design and final equipment assumptions should be verified before implementation.

Frequently asked questions

Why compare on cost per dry tonne?

Water is paid for but has no feed value. Dividing the net price by the dry-matter share puts lots with different moisture on the same basis.

Where do the deduction rates come from?

From your own contract or trade terms. The calculator has no standard scale; the defaults are examples only.

Why is a rejectable lot not priced?

A lot above a rejection limit is not a discounted lot — under most contracts you can refuse it. Pricing it would make an unusable lot look cheap.

Does FeedMatch test the lots?

No. FeedMatch compares supplier offers on a common specification; analysis comes from the agreed laboratory.
