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.
Best Answer: The normal gestation period of ewes is approximately 147 days, ranging from 144 to 152 days. The medium-wool breeds and meat-type breeds ordinarily have a shorter gestation period than do the fine-wool breeds.High temperatures and high nutrition levels may shorten the gestation period two or three days.
