Pig Feed Feed Conversion Calculator

Use this pig feed feed conversion to turn farm records and planning assumptions into a clear working estimate. Enter values on a consistent weight and moisture basis, then review the main result, supporting totals, and gap against your plan. The calculator runs entirely in your browser and is intended for budgeting and operational planning; actual needs can vary with animals, weather, feed quality, equipment, and management.

Calculator

Farm planning inputs
lb
Feed actually consumed during the period.
lb
Measured liveweight gain on the same period.
$/lb
Average cost of feed consumed.
lb/lb
Feed units expected per output unit.

How to use this calculator

  1. Enter current farm values using the units shown.
  2. Keep all feed weights on the same as-fed or dry-matter basis.
  3. Select Calculate and review the main estimate.
  4. Check the supporting results for capacity, cost, loss, or target gap.
  5. Reset the form before testing a different scenario.

Formula

Feed conversion ratio = feed consumed ÷ useful output
Feed cost per output unit = feed consumed × feed price ÷ output

What the result means

A lower ratio means less feed was used per unit of measured output. Compare only periods using the same feed and output definitions.

Planning estimate only. Validate assumptions against current records and professional guidance.

Example calculation

With 5,000 lb feed and 2,800 lb gain, FCR is 1.79:1. At $0.18/lb feed, feed cost is about $0.32 per pound of gain; versus a 1.70 target, feed use is 240 lb high.

Tips for better results

  • Use recent scale tickets, invoices, or meter readings instead of memory.
  • Keep time periods and weight bases consistent.
  • Run a conservative case for loss, weather, or performance.
  • Compare the estimate with actual records during the period.
  • Update inputs when prices, rations, group size, or conditions change.

Frequently asked questions

Which records should I use for this pig feed feed conversion?

Use records from the same group and time period, and keep all weights and concentrations on one consistent basis.

Can I use kilograms instead of pounds?

Yes. Ratio-based results work with any consistent weight unit; any displayed lb label should be read as your chosen unit.

How should I handle dry matter versus as-fed values?

Do not mix them. Convert every feed quantity and concentration to either dry matter or as-fed values before calculating.

Why might the actual result differ from this estimate?

Weather, feed analysis, wastage, health, equipment, and measurement timing can all change actual performance.

Is this result a feeding recommendation?

No. It is a planning estimate. Confirm rations, nutrient targets, and animal needs with a qualified nutrition or livestock professional.
