Agriculture Feed Conversion Ratio

A livestock efficiency KPI. Distinct from Healthcare ops tools.

FCR = feed ÷ gain (lower is more efficient).

Tip: Keep “Feed Intake” and “Weight Gain” on the same basis (period, units, and population) before calculating Agriculture Feed Conversion Ratio.

Feed conversion ratio (FCR) divides feed intake by live-weight gain over the same period.

Enter feed and gain in matching mass units.

Understanding Agriculture Feed Conversion Ratio

How we calculate. FCR = feed ÷ gain (lower is more efficient). The form uses the same arithmetic as the worked examples on this page. See our methodology and accuracy policy.

Real-world scenario: A typical Agriculture Feed Conversion Ratio case uses feed intake 300 and weight gain 100. Enter the same figures below to reproduce the worked path.

What is Agriculture Feed Conversion Ratio?

A livestock efficiency KPI. Distinct from Healthcare ops tools.

  • Same period
  • Matching mass units
  • Gain > 0

The Formula

Feed Conversion Ratio
FCR = Feed intake ÷ Weight gain

Worked Example

Scenario: Feed 300 kg; gain 100 kg.
Step 1: 300 ÷ 100 = 3
Answer: FCR is 3.0.

Common Use Cases

  • Homework: animal science
  • Farm: batch performance
  • Study: efficiency tracking

Pro Tips

  • Freeze as-fed vs dry-matter
  • Lower FCR = better
  • Not veterinary advice

Limitations: Agriculture Feed Conversion Ratio results are educational agriculture and farm-planning aids—not agronomic prescriptions, pesticide labels, veterinary advice, or legal compliance. Confirm units and recommendations with your extension service, agronomist, or instructor.

FAQ

Is lower better?

Yes for classic FCR—less feed per unit gain.

Same as crop yield?

No. FCR is feed÷gain for livestock; yield is crop production÷area.
