What the worksheet does not knowAssumptions to check
  • Use dated project weights from your own scale tickets or project notes.
  • Target weight and target date are optional for basic ADG. When you use them, take those values from your fair book, show office, advisor, ag teacher, or Extension office.
  • This calculator compares weight pace only. It does not give nutrition, veterinary, withdrawal, health, sale, eligibility, or fair-rule advice.
  • If dates are blank, you may enter day counts directly. Dates must move forward for gain calculations to run.
