  • Health of the Cow: The overall health and nutrition of the cow can affect the length of the gestation period.
  • Environmental Conditions: Stressful or adverse environmental conditions can impact the gestation period.
  • Sex of the Calf: The sex of the calf can also play a role, with some studies suggesting that male calves may have a slightly longer gestation period than female calves 3.
