Separate formulation value from performance assumptions
The reformulated diet cost represents the diet cost at 100% of the matrix you choose to evaluate. The utilization control then stress-tests that formulation saving at 25%, 50%, 75%, 100%, or any custom value. An expected FCR can be entered separately; leaving it equal to the current FCR models formulation economics only.
How matrix credits are handled
Optional phosphorus and calcium credits are entered as percentage points and displayed as kilograms of nutrient credit per metric tonne at the selected matrix utilization. Optional energy credit is displayed in kcal/kg. These audit values do not independently change diet cost; the entered reformulated diet cost is the economic formulation input, avoiding double-counting.
Frequently asked questions
Does this calculator recommend an enzyme dose or matrix?
No. Dose, matrix values, diet cost changes, and performance expectations come from the user or a source the user trusts.
Why enter reformulated diet cost instead of automatically removing phosphate or other ingredients?
A complete formulation has multiple nutrient and ingredient constraints. Until the least-cost formulation engine is added, entering the reformulated cost from qualified formulation software is the more defensible approach.
