Cow Gestation Period

An average, cow gestation period (length of cow pregnancy) lasts about 283 days, however, this period varies based on the breed of the cow and the sex of the calf. That's about 9 months.

If you're breeding cattle it's important to know when the calves might come. Depending on the age of the cow, the breed of cattle, how healthy the cow is, the sire, and other considerations this will change the date of the birth.


Often, cattle operations will calculate the cow's due date by adding 283 days to the breeding date. If you have a rough guess when that was you can count back. If you need a gestation calculator you're in luck, you can find that below.


Average Cow Gestation Period

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 pregnancies may last 10 days less. So, the typical gestation period for cattle ranges from 279 to 287 days (up to 291 for Brahman cattle).


Check out the gestation table for cattle below to estimate your cow's due date based on their date of service.


Pregnancy management starts by keeping accurate cattle records to know when the cow was exposed to the bull. Then as the date gets closer make sure you're prepared for calving by keeping a close eye on your herd, and needed supplies close at hand.


You can also use our Free Cow Gestation Calculator to estimate for you or print this downloadable cattle gestation period table to help you find the gestation period for your cows.
