About cattle gestation

The average gestation period for a cow is 283 days (around 9 months and 10 days), though it can range from 279 to 287 days depending on breed and individual animal. Knowing the expected calving date helps you plan dry-off, nutrition, vaccinations and calving pen preparation.

  • Dry off dairy cows ~60 days before calving.
  • Increase energy and protein in the final trimester.
  • Move cows to a clean calving area 1–2 weeks before the due date.
