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. Length of gestation is primarily an inherited trait, but has nothing to do with the rate of maturity of a certain breed or an individual animal.
Mature cows weigh between 1,000 and 1,500 pounds, reaching peak physical maturity at 8 to 10 years of age. They can live to be 30 years old or longer. With good management, cows can reproduce every year and can begin breeding at 2 years of age. The normal gestation period is 280 to 285 days.
