Full Answer

The ideal gestation for each heifer is one calf every year. Gestation periods vary depending on breed, however, as reported in a 2013 issue of the Angus Beef Bulletin. Breeders document gestation lengths according to whether the breeding is natural or through artificial insemination, which is why a nine-month average is considered the median gestation period for all cattle.
