What is Agriculture Average Daily Gain?

A livestock growth KPI. Complements Wave 1 FCR (feed÷gain).

  • Same period
  • Days > 0
  • Matching mass units

The Formula

Average Daily Gain
ADG = Weight gain ÷ Days

Worked Example

Scenario: Gain 90 kg; days 100.
Step 1: 90 ÷ 100 = 0.9
Answer: ADG is 0.9 per day.

Common Use Cases

  • Homework: animal growth
  • Farm: trial summaries
  • Study: pair with FCR

Pro Tips

  • Use live-weight gain
  • Not veterinary advice
  • Pair with Wave 1 FCR

Limitations: Agriculture Average Daily Gain 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.

  • Rounding too early: Carry extra decimal places through multi-step work before rounding the final percent.
  • Mixing percent and decimal forms: Enter rates in the format the calculator labels expect.
