An average cow gestation period (length of pregnancy) lasts on about 283 days, however this period does vary based on the breed of the cow and the sex of the calf.
While the average cow gestation period is 283 days, calving for older and larger cows usually happens 10 days later. Smaller and younger cow’s pregnancy may last 10 days less. The typical gestation period for cattle ranges from 279 to 287 days (up to 291 for Brahman cattle).
