There is some variation in gestation period for different breeds of cows, but not much. An all-breed average is about 283 days, with the breed-specific averages ranging from approximately 279-292 days. Individual animals may vary, however, and it is not unusual for a cow to deliver anytime between a couple of weeks before her due date to a couple of weeks after.
Good question! On average, cows of all breeds have an average gestation period of approximately 274.9 days.

Gestation periods for different breeds of dogs only vary slightly. The average gestation period for dogs is nine to ten weeks.
The following breeds have a short gestation period (note that not all breeds with short gestation periods will be listed here):AngusDexterGuernseyJerseyMeuse Rhine IsselRed AngusSpeckle ParkIt was originally believed that rate of maturity was correlated with rate of gestation. This is now not the case. Rate of maturity is simply carcass maturity, or the time when an animal starts to lay down fat, and has nothing to do with age of puberty nor gestation length.
The length of gestation of a Nguni is quite variable depending on where it's raised and the producer raising them. According to the Nguni Cattle Breeders' Society By-laws, Nguni cattle are allowed to have a minimum gestation period of 266 days and a maximum period of 308 days. See the related link below.
Since Simmentals are typically those that are later maturing than other breeds, the gestation is usually 286 to 293 days in length.
63 DaysThe gestation period is the same in all breeds of dogs. Anywhere from 58 to 63 days.
The gestation period of a Chauri cow (which is a cross between a yak and a domestic bovine of Bos primigenius indicusbreeding) is around 9 to 10 months in length, which translates to around 290 to 315 days in length.
The Okapis gestation period is about 458 days on average
There is no such cattle breed as a "Dutch Bleed", so the question has no merit.
The average gestation period for a bison is around 9 months.
The average duration of the human gestation period is about 9 months.
