How the dates are worked out
- Bred on = the preg-check date − days bred, or the date bred you enter.
- Calves on = bred on + gestation.
- For a calf: bred on = born on − gestation.
- Gestation starts at 283 days. It varies from cow to cow and by sire, so treat every date here as a guide.
- Your last entries and gestation are remembered in this browser. The preg-check date starts at today each visit.
