Yes, cows do get pregnant, and their pregnancy lasts for a specific duration.
A cow's gestation period, or pregnancy, is approximately 9 months and 10 days (around 283 days). During this time, the calf develops inside the cow's uterus. After the gestation period, the cow gives birth to a calf. Typically, a newborn calf weighs about 45 pounds and is able to stand and walk relatively soon after birth, often within an hour.
