Notes: Add weigh-in, fair-book, or advisor questions before printing.

BarnMath checks weight math only. Check rules in your fair book, and take animal-health questions to your advisor or veterinarian.
Review notes
  • Enter starting and current weights before relying on the ADG line.
  • Enter a target weight from your fair book, show office, advisor, ag teacher, or Extension office.

Assumptions

What the worksheet does not know

  • Use dated project weights from your own scale tickets or project notes.
  • Enter a target weight and target date 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.
