On average, the gestation period or length-of-pregnancy of a cow is 285 days long. This is similar to the pregnancy period of a woman, which is closer to around 9 months or ~260 days.

However, actual gestation period of a cow can range from 270 days to 295 days, depending primarily on breed[s], age, body condition and nutritional health. Gestation period is also controlled by genetics, but not rate of maturity. The rate of maturity is more to do with the age a bovine reaches when it starts to put fat down, not muscle, and has very little to nothing to do with reproductive characteristics including length of gestation.

Here are some rules of thumb to remember when trying to figure out how long your cows or heifers will be pregnant for:

  • Heifers that are pregnant for the first time will most likely have a little longer gestation period than older, mature cows. This is typically because heifers are still growing themselves and have to put energy into growing a calf AND their own bodies, including the formation and maturation of their udder.
  • Cows with poorer fertility (or have a tougher time getting bred again after giving birth) may have a longer gestation period than those with good fertility (or those that have settled during the first part of the breeding season after a 45 to 60 day rest period).
  • Usually small cows have a shorter gestation period than big cows, but not always. For instance, Texas Longhorns have a longer gestation period than South Devons, but TL's are smaller in size and lighter in weight than SD's. However, this might be applicable if comparing Jerseys with Charolais or moderate-framed Angus with Chianina.
  • Thin cows may have a shorter gestation than normal-condition cows, and fat cows may have a longer gestation than normal-conditioned cows.
  • Females that have more masculine characteristics may have a longer gestation than those females that are more feminine in conformation.

Do all cows have the same gestation period?

Not really. On average they are similar (around 285 days) but NEVER the EXACT same. For instance, a Jersey cow will have a shorter gestation period than a Charolais cow, and a thin Angus heifer will have a longer pregnancy than a normally-conditioned cow of the same breed. How long a cow's gestation period depends on breeding, health, conformation and age. See the related question below for more information on this.
