What is the longest gestation period of a cow?

The longest gestation period recorded in cows is held by the African elephant, not cows themselves. African elephants have a gestation period of approximately 22 months. In comparison, the gestation period of a cow typically ranges from 279 to 290 days, depending on the breed. It's important to note that the gestation period can vary slightly among individual cows, but it generally falls within this timeframe. Proper monitoring and care during pregnancy are essential to ensure the health and well-being of both the cow and the developing calf.
